    Comparing a multi-linear (STEP) and systemic (FRAM) method for accident analysis2010Inngår i: RELIABILITY ENGINEERING and SYSTEM SAFETY, ISSN 0951-8320, Vol. 95, nr 12, s. 1269-1275Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Accident models and analysis methods affect what accident investigators look for, which contributory factors are found, and which recommendations are issued. This paper contrasts the Sequentially Timed Events Plotting (STEP) method and the Functional Resonance Analysis Method (FRAM) for accident analysis and modelling. The main issue addressed in this paper is the comparison of the established multi-linear method STEP with the new systemic method FRAM and which new insights the latter provides for accident analysis in comparison to the former established multi-linear method. Since STEP and FRAM are based on a different understandings of the nature of accidents, the comparison of the methods focuses on what we can learn from both methods, how, when, and why to apply them. The main finding is that STEP helps to illustrate what happened, involving which actors at what time, whereas FRAM illustrates the dynamic interactions within socio-technical systems and lets the analyst understand the how and why by describing non-linear dependencies, performance conditions, variability, and their resonance across functions.

    A Systematic Literature Review of "Usability Inspection Methods"2013Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    Objective: Usability inspection methods are a class of usability evaluation methods, applied by usability evaluators to assess usability related aspects of different user interfaces. Different usability inspection methods are proposed so far to evaluate user interfaces in a better way. This systematic literature review summarized different usability evaluation methods, with more focus on two widely used inspection methods. The review also summarized the problems with these two methods and probable proposed solution to cope with these problems.

    Method: A systematic review method as described by Kitchenham [3] was followed to carry out this review. The identified problems in the review were structured in a form of questions. The search to find the relevant data that address the identified questions were conducted on the basis of planned search strategies. Papers were selected on the basis of inclusion and exclusion criteria in accordance with the quality checklist; followed by data extraction and synthesis strictly characterized by quality checklist, inclusion and exclusion criteria to attain better results.

    Results and discussion: Despite of its advantages there still exists many weaknesses in Heuristic evaluation (HE) and Cognitive walk-through (CW) methods. Different studies have highlighted different factors that may influence the results. Those factors include number of evaluators, evaluator’s perception and experience, time, environment, cost, indigenous design, the way method applied and acquired software.

    Conclusion: To get better evaluation results, it is best to use different techniques for usability evaluation of single software or optimize existing techniques.

    Comparing machine translation and human translation: A case study2017Inngår i: RANLP 2017 The First Workshop on Human-Informed Translation and Interpreting Technology (HiT-IT) Proceedings of the Workshop, September 7th, 2017 / [ed] Irina Temnikova, Constantin Orasan, Gloria Corpas and Stephan Vogel, Shoumen, Bulgaria: Association for Computational Linguistics , 2017, s. 21-28Konferansepaper (Fagfellevurdert)
    Abstract [en]

    As machine translation technology improves comparisons to human performance are often made in quite general and exaggerated terms. Thus, it is important to be able to account for differences accurately. This paper reports a simple, descriptive scheme for comparing translations and applies it to two translations of a British opinion article published in March, 2017. One is a human translation (HT) into Swedish, and the other a machine translation (MT). While the comparison is limited to one text, the results are indicative of current limitations in MT.

    Converting an English-Swedish Parallel Treebank to Universal Dependencies2015Inngår i: Proceedings of the Third International Conference on Dependency Linguistics (DepLing 2015), Association for Computational Linguistics, 2015, s. 10-19, artikkel-id W15-2103Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The paper reports experiences of automatically converting the dependency analysis of the LinES English-Swedish parallel treebank to universal dependencies (UD). The most tangible result is a version of the treebank that actually employs the relations and parts-of-speech categories required by UD, and no other. It is also more complete in that punctuation marks have received dependencies, which is not the case in the original version. We discuss our method in the light of problems that arise from the desire to keep the syntactic analyses of a parallel treebank internally consistent, while available monolingual UD treebanks for English and Swedish diverge somewhat in their use of UD annotations. Finally, we compare the output from the conversion program with the existing UD treebanks.

    Swedish prepositions are not pure function words2017Inngår i: Proceedings of the NoDaLiDa 2017 Workshop on Universal Dependencies, 22 May, Gothenburg, Sweden / [ed] Marie-Catherine de Marneffe, Joakim Nivre, and Sebastian Schuster, Linköping: Linköping University Electronic Press, 2017, Vol. 135, s. 11-18Konferansepaper (Fagfellevurdert)
    Abstract [en]

    As for any categorial scheme used for annotation, UD abound with borderline cases. The main instruments to resolve them are the UD design principles and, of course, the linguistic facts of the matter. UD makes a fundamental distinction between content words and function words, and a, perhaps less fundamental, distinction between pure function words and the rest. It has been suggested that adpositions are to be included among the pure function words. In this paper I discuss the case of prepositions in Swedish and related languages in the light of these distinctions. It relates to a more general problem: How should we resolve cases where the linguistic intuitions and UD design principles are in conflict?

    Towards a research infrastructure for translation studies.2014Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    In principle the CLARIN research infrastructure provides a good environment to support research on translation. In reality, the progress within CLARIN in this area seems to be fairly slow. In this paper I will give examples of the resources currently available, and suggest what is needed to achieve a relevant research infrastructure for translation studies. Also, I argue that translation studies has more to gain from language technology, and statistical machine translation in particular, than what is generally assumed, and give some examples.

    Natural Language Processing for the Translation Class2013Inngår i: Proceedings of the second workshop on NLP for computer-assisted language learning at NODALIDA 2013: NEALT Proceedings Series 17 / [ed] Elena Volodina, Lars Borin, Hrafn Loftsson, Linköping: Linköping University Electronic Press, 2013, s. 1-10Konferansepaper (Fagfellevurdert)
    Abstract [en]

    We propose a system for use in translation teaching with automatic support for alignment and comparative assessment of different translations. A primary use of this system is for discussion in class and comparison of student translations from a given source text, but it may also be used to study and compare differences between published translations. We describe the intended functions of the system and give suggestions on its design and architecture. We also discuss the degree of automation that can be expected and report results from a small indicative study focused on word alignment performance.

    Translation Class Instruction as Collaboration in the Act of Translation2014Inngår i: Proceedings of The 9th Workshop on Innovative Use of NLP for Building Educational Applications, Baltimore, USA, June 26th, 2014. / [ed] Joel Tetreault, Jill Burstein, Claudia Leacock, The Association for Computational Linguistics , 2014, s. 34-42Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The paper offers an effective way of teacher-student computer-based collabo-ration in translation class. We show how a quantitative-qualitative method of analysis supported by word alignment technology can be applied to student translations for use in the classroom. The combined use of natural-language pro-cessing and manual techniques enables students to ‘co-emerge’ during highly motivated collaborative sessions. Within the advocated approach, students are pro-active seekers for a better translation (grade) in a teacher-centered computer-based peer-assisted translation class.

    Similarity-Based Alignment of Monolingual Corpora for Text Simplification2016Inngår i: CL4LC 2016 - Computational Linguistics for Linguistic Complexity: Proceedings of the Workshop, The COLING 2016 Organizing Committee , 2016, s. 154-163Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Comparable or parallel corpora are beneficial for many NLP tasks.  The automatic collection of corpora enables large-scale resources, even for less-resourced languages, which in turn can be useful for deducing rules and patterns for text rewriting algorithms, a subtask of automatic text simplification. We present two methods for the alignment of Swedish easy-to-read text segments to text segments from a reference corpus.  The first method (M1) was originally developed for the task of text reuse detection, measuring sentence similarity by a modified version of a TF-IDF vector space model. A second method (M2), also accounting for part-of-speech tags, was devel- oped, and the methods were compared.  For evaluation, a crowdsourcing platform was built for human judgement data collection, and preliminary results showed that cosine similarity relates better to human ranks than the Dice coefficient. We also saw a tendency that including syntactic context to the TF-IDF vector space model is beneficial for this kind of paraphrase alignment task.

    DESIGN OF A DISTRIBUTED HUMAN FACTORS LABORATORY FOR FUTURE AIRSYSTEMS2018Inngår i: ICAS congress proceeding, International Council of the Aeronautical Sciences , 2018, artikkel-id ICAS2018_0305Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    This paper presents a rationale for structuring a distributed human factors laboratory for future air systems. The distributed herein refers to two aspects: content and geographic. As for content, the laboratory is structured in two levels, namely, individual, and team. As for geographic, the laboratory infrastructure is distributed in three physically separate facilities, namely, Department of Computer and Information Science (IDA) and Department of Management and Engineering (IEI) from Linköping University – Sweden and the Competence Center in Manufacturing from the Aeronautics Institute of Technology (ITA) – Brazil.

    Engine Failure Induced Task Load Transient for Simulation Based Certification Aiding for Aircraft2018Inngår i: ADVANCES IN HUMAN ASPECTS OF TRANSPORTATION, SPRINGER INTERNATIONAL PUBLISHING AG , 2018, Vol. 597, s. 79-86Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This study is one of a series of studies, researching various aspects that all aim at enhanced simulation based certification aiding for aircraft. An experimental within-group design study was performed with 10 participants ( 5 male, and 5 female). The results showed a significant difference, F(2,16) = 5.11, p = 0.019, in mental workload between an engine failure condition and an normal condition for eye blink frequency. No effect of speed at the engine failure event on mental workload was found.

    Design av en användarvänlig Androidapplikation för trådlös kommunikation med Electronic Control Unit för bil eller testmiljö2015Independent thesis Basic level (university diploma), 10,5 poäng / 16 hpOppgave
    Abstract [sv]

    Det här examensarbetet har utförts inom programmet högskoleingenjör datateknik vid Linköpings Universitet under våren 2015 och utförts på begäran av ArcCore i Linköping. Syftet med det här examensarbetet är att skapa och designa en användarvänlig Androidapplikation som trådlöst kan kommunicera med electronic control units i bil eller testmiljö.

    Androidapplikationen består av fem huvudskärmar, fyra vars uppgift är att skriva ut informationen som åker över CAN bussen. De fem skärmarna är start, felkoder, sensorer, ECU extract och overview. Start tar dig vidare till de andra skärmarna, felkoder skriver ut alla felkoder, sensorer skriver ut alla sensorvärden, ECU extract skriver ut all information och overview visar en virtuell instrumentbräda. Användarutvärderingar har utförts för att ta fram både designen och layouten på applikationen. Utvecklingsprocessen för att få fram applikationen har genomförts med hjälp av utvecklingsmetoden extreme programming och utvärderingar har utförts med traditional usability tests och binary success. Utvärderingarnas feedback har använts för att utveckla både designen och användarvänligheten på applikationen.

    Androidapplikationen har utvecklats i Android Studio och kommunicerar med ECU:erna med hjälp av en PEAK PCAN wireless gateway som kopplats upp mot Hercules Development Kit TMS570 MCU.

    Resultatet är att vi tydligt kan se att användarvänligheten har ökat under utvecklingsprocessen och att vi nu med hjälp av utvärderingar har en snygg och lättanvändarvänlig Android applikation som kommer kunna användas av alla som vill ta del av informationen som finns på CAN bussen.

    Selenium-Testing as a Service2016Independent thesis Basic level (degree of Bachelor), 10,5 poäng / 16 hpOppgave
    Abstract [en]

    Selenium has been a method to test web applications for over a decade, it is interacting directly with the browser and has gained support from both browsers and the community. With the growing amount of browsers, mobile devices and operating systems which a web application is expected to work with, services providing these systems for testing web applications against has gained interest. These services provide testing as a service (TaaS), and runs Selenium-tests in the cloud. This research tried to compare the different services with each other in regard to flexibility, cost, simplicity and reliability. I have also tried to see differences between running the tests locally and using these services. The results showed that there are some differences between the services, and the one best suited might depend on the web application.

    Mission Experience: How to Model and Capture it to Enable Vicarious Learning2013Licentiatavhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Organizations for humanitarian assistance, disaster response and military activities are characterized by their special role in society to resolve time-constrained and potentially life-threatening situations. The tactical missions that these organizations conduct regularly are significantly dynamic in character, and sometimes impossible to fully comprehend and predict. In these situations, when control becomes opportunistic, the organizations are forced to rely on the collective experience of their personnel to respond effectively to the unfolding threats. Generating such experience through traditional means of training, exercising and apprenticeship, is expensive, time-consuming, and difficult to manage.

    This thesis explores how and why mission experience should be utilized in emergency management and military organizations to improve performance. A multimedia approach for capturing mission experience has further been tested in two case studies to determine how the commanders’ experiences can be externalized to enable vicarious learning. These studies propose a set of technical, methodological, and ethical issues that need to be considered when externalizing mission experience, based on two aforementioned case studies complemented by a literature review. The presented outcomes are (1) a model aligning abilities that tactical organizations need when responding to dynamic situations of different familiarity, (2) a review of the usefulness of several different data sources for externalization of commanders’ experiences from tactical operations, and (3) a review of methodological, technical, and ethical issues to consider when externalizing tactical military and emergency management operations. The results presented in this thesis indicate that multimedia approaches for capturing mission histories can indeed complement training and exercising as a method for generating valuable experience from tactical missions.

    2012 (engelsk)Inngår i: ISCRAM 2012 Conference Proceedings. Book of Papers. 9th International Conference on Information Systems for Crisis Response and Management / [ed] Leon Rothkrantz, Jozef Ristvej and Zeno Franco, ISCRAM , 2012Konferansepaper, Publicerat paper (Fagfellevurdert)
    Abstract [en]

    A tactical organisation can be seen as an adhocracy designed to perform missions in uncertain, ambiguous and complex environments. Flexibility, adaptability, resilience, innovation, creativity and improvisation have all been identified as key skills for successful outcome of these missions. To learn skills associated with such abilities previous research has shown that knowledge acquired through experience plays an important role. It is therefore important that individuals, teams and organisations share and learn from experiences to improve their ability to cope with novel situations. In literature there is a lack of consistency in how these abilities are discussed, we therefore propose the FAIRIC model to help define and differentiate between the concepts. By unravelling some of the similarities and differences we create a common vocabulary to discuss knowledge gained from experience. This can help classify different experiences and provide a more systematic way of gathering knowledge on situational factors that influence the success of different actions and more unified interpretations that can assist design of knowledge representations to share mission experience over boundaries of time and space.

    Abstract [en]

    In this paper we present the Reconstruction and Exploration approach (R&E) and F-REX tool and their applications in a field exercise with the Swedish Rescue Services Agency with the purpose of investigating features needed for a computer supported approach for evaluation of large scale crisis management operations. After the exercise several interviews and one seminar were held to evaluate R&E as a representative for computer supported evaluation approaches for crisis management operations. Initial results indicate that multimedia presentation of key events from an operation can be very valuable not only to stimulate the participants to reflect on their own performance, but also to document and share lessons learned to non-participants.

    Abstract [en]

    This study presents an approach for computer-supported reconstruction and exploration (R&E) of distributed tactical operations. The approach involves several steps for constructing a time-synchronized, event-driven multimedia model of the course of events collected from multiple sources in the operational environment and visualizes this model in the F-REX Studio multimedia suite. In this study, the use of R&E and F-REX is explored in large-scale emergency management exercises. The approach’s possibilities, limitations, and needs for modification are first outlined followed by a comparison to traditional quantitative and qualitative data collection methods applied in the same context. It is found that the R&E approach in combination with F-REX has several advantages in relation to the other methods, in terms of avoiding problems of retrospection and in being able to provide an overview of the entire operation based on multiple perspectives—addressing the question “why” something happened rather than “what happened.” Correctly used, multimedia-supported R&E can thereby be used for more solid evaluations of large-scale emergency management exercises and operations, thus contributing to more effective handling of future crises.

    Abstract [en]

    In this study, thoughts on ethics of workplace monitoring are being applied to the very special domain of evaluations of tactical operations, such as military or crisis management exercises or operations. I try to find out if there are differences in the way we should regard workplace monitoring when it comes to this domain compared to standard workplaces such as offices, since the purpose of the surveillance is not to enforce discipline, but to evaluate the organizations’ ability to conduct a tactical operation. The study focuses on issues such as privacy and informed consent and the main purpose of the investigation is to structure a consistent ethical standpoint when it comes to operations’ evaluation by making parallels to related theories that I found correct and applicable. I conclude that is indeed reasonable to place other demands on crisis management workers than we would do on other work forces, and that it should therefore be easier to motivate workplace monitoring for the purpose of evaluating distributed tactical operations. I argue however, just as Miller does regarding police work, that upholding privacy can be a real problem when crisis management personnel are exposed to monitoring, even though it is intended for evaluation.

    Evaluation of Crisis Management Operations using Reconstruction and Exploration2008Inngår i: Proceedings of the 5th International ISCRAM Conference, Washington, DC: May 4-7 / [ed] Frank Fiedrich and Bartel Van de Walle, ISCRAM , 2008, s. 118-125Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In this paper we present the Reconstruction and Exploration approach (R&E) and F-REX tool and their applications in a field exercise with the Swedish Rescue Services Agency with the purpose of investigating features needed for a computer supported approach for evaluation of large scale crisis management operations. After the exercise several interviews and one seminar were held to evaluate R&E as a representative for computer supported evaluation approaches for crisis management operations. Initial results indicate that multimedia presentation of key events from an operation can be very valuable not only to stimulate the participants to reflect on their own performance, but also to document and share lessons learned to non-participants.

    Sharing Mission Experience in Tactical Organisations2012Inngår i: ISCRAM 2012 Conference Proceedings. Book of Papers. 9th International Conference on Information Systems for Crisis Response and Management / [ed] Leon Rothkrantz, Jozef Ristvej and Zeno Franco, ISCRAM , 2012Konferansepaper (Fagfellevurdert)
    Abstract [en]

    A tactical organisation can be seen as an adhocracy designed to perform missions in uncertain, ambiguous and complex environments. Flexibility, adaptability, resilience, innovation, creativity and improvisation have all been identified as key skills for successful outcome of these missions. To learn skills associated with such abilities previous research has shown that knowledge acquired through experience plays an important role. It is therefore important that individuals, teams and organisations share and learn from experiences to improve their ability to cope with novel situations. In literature there is a lack of consistency in how these abilities are discussed, we therefore propose the FAIRIC model to help define and differentiate between the concepts. By unravelling some of the similarities and differences we create a common vocabulary to discuss knowledge gained from experience. This can help classify different experiences and provide a more systematic way of gathering knowledge on situational factors that influence the success of different actions and more unified interpretations that can assist design of knowledge representations to share mission experience over boundaries of time and space.

    Approaches to team performance assessment: a comparison of self-assessment reports and behavioral observer scales2017Inngår i: Cognition, Technology & Work, ISSN 1435-5558, E-ISSN 1435-5566, Vol. 19, nr 2-3, s. 517-528Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Human factors research popularly employs perception-based techniques to investigate team performance and its dependency to cognitive processes. Such studies frequently rely upon either observer-based or self-assessment techniques to collect data. In this study, we examined behavioral observer ratings and self-assessment ratings for measuring team performance in virtual teams, with team performance regarded as a combination of task outcome and team cognition. Juxtaposing self-assessments and observer ratings from a quasi-experiment comparing team performance rating techniques reveals that they indeed produce overall similar results, with both singling out teamwork effectiveness ratings as the strongest contributor to overall team performance. However, the comparisons show remarkably low correlation on individual questionnaire items. The most striking difference is that the team members self-assessments of workload are lower than the corresponding observer ratings. In particular, the self-assessments do not correlate at all with overall team performance, whereas the observers workload ratings are more consistent with contemporary research that suggests a strong correlation between workload and team performance, suggesting that observer-based techniques are more reliable than self-assessments for assessing workload. For other ratings, the results show that the two techniques are fairly equal, suggesting that the choice between methods to employ can be deferred to other considerations such as obtrusiveness, accessibility, and resource availability.

    Implementing touch interaction in a casual mobile game2014Independent thesis Basic level (degree of Bachelor), 10,5 poäng / 16 hpOppgave
    Abstract [en]

    This thesis is to help developers in the touch design of casual games. The thesis work was made on the development platform Gideros Mobile and much of the thesis theory and methods will be based on that work. The purpose of the report is to show what one should think about when making a casual game in a touch design perspective, like taking into account that most people are used to one type of input design (like swiping or tapping), that you should design the game with the purpose to reach out to as a large audience as possible (taking into account people with disabilities) and some small notes on what should be avoided so not to deter people from wanting to play the game. It is important to note that this thesis is built for the purpose of mobile casual games, others will probably not find this thesis relevant.

    Assessment and Improvement of Initial Learnability in Complex Systems: A Qualitative Study to Promote Intuitive Software Development2016Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    This Master’s Thesis aimed to assess and propose improvements for initial learnability in Sectra AB’s Picture Archiving Communication System (PACS) by integrating usability engineering and agile software development. Assessing initial learnability and re-designing complex systems is difficult as they have a high skill cap and take longer time to learn in comparison to simpler ones. Further, companies that use agile methodologies often focus on completing small items which might hide the overarching vision of a product that can lead to usability problems. While there are several methods for assessing usability, no research has specifically focused on assessing initial learnability in complex systems. This study however investigates how this may be achieved by combining current methodologies for measuring learnability with usability engineering and agile software development. Initial learnability issues and needs were assessed after evaluating Sectra PACS using 5 participants and analysed using impact mapping as well as conducting a focus group within the organisation that owns the product.

    Användarbehov och kontextuella krav för val av mobil interaktionsteknik: Behovs- och användarundersökning i Scanias verkstäder2016Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [sv]

    Mobil informationsteknik har på senaste tiden fått mer uppmärksamhet inom industriella applikationer, inte minst inom underhåll och reparation där teknisk dokumentation förekommer i stor utsträckning. Scania har tagit fram ett nytt koncept för interaktion med teknisk dokumentation i verkstaden där en viktig del av konceptet är mobilitet. Scanias förhoppningar är att en ökad möjlighet till mobilitet ska kunna förbättra användarupplevelsen.

    I detta arbete har en observationsstudie genomförts för att identifiera användarnas behov av mobilitet vid reparation och underhållsarbete samt de kontextuella faktorer som påverkar val av mobil interaktionsteknik.

    Fyra olika behov av mobilitet kunde identifieras efter analysen och till dessa kunde olika krav knytas för att skapa ett underlag för bedömning av olika teknikers potential att uppfylla de aktuella behoven.

    Utveckling av tvådimensionellt online-spel i kategorin action-strategi för smartphones med fokus på spelupplevelse och prestanda2017Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [sv]

    Vid utveckling av spel till smartphones så krävs ofta flera olika implementationer för olika plattformar. Men det finns olika spelmotorer och ramverk till olika programspråk som kan kompilera samma kod till flera olika mobila plattformar. Kivy är ett sådant ramverk för programspråket Python.

    I detta arbete användes prototypdriven utveckling i Kivy för att försöka höja spelupplevelsen av ett tvådimensionellt online-spel i kategorin action-strategi som tidigare fanns implementerat i GameMaker. Olika tekniker för att öka prestandan för spelet testades också. Det visade sig att med den bästa kombinationen av de tekniker som testades så blev prestandan med hög last cirka 29 bilder/s. Användarbarheten, spelbarheten och ljud-estetiken av spelet ökades medan nöjet och den personliga tillfredställelsen från spelet minskade. Totalt sett blev spelupplevelsen i stort sätt oförändrad.

    Bluetooth Low Energy and Smartphones for Proximity-Based Automatic Door Locks2014Independent thesis Basic level (degree of Bachelor), 10,5 poäng / 16 hpOppgave
    Abstract [en]

    Bluetooth Low Energy is becoming increasingly popular in mobile applications due to the possibility of using it for proximity data. Proximity can be estimated by measuring the strength of the Bluetooth signal, and actions can then be performed based on a user's proximity to a certain location or object. One of the most interesting applications of proximity information is automating common tasks; this paper evaluates Bluetooth Low Energy in the context of using smartphones to automatically unlock a door when a user approaches the door. Measurements were performed to determine signal strength reliability, energy consumption and connection latency. The results show that Bluetooth Low Energy is a suitable technology for proximity-based door locks despite the large variance in signal strength.

    Desirability in the development of In-Car Infotainment Systems2011Inngår i: Workshop: User Experience in Cars / [ed] David Wilfinger, 2011Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    This paper describes a workflow for designing experiences whileinteracting with an advanced driver assistant system. Future driver assistancesystems that utilize sensors and Car2X-communication in order to detect threatsin the car environment can help the driver to avoid collisions. To increase theacceptance of such a system, the interaction between the driver and the systemshould be able to generate positive experiences. To generate those experiences,a story-based design workflow was used. Concepts created with this workflowshould be able to address specific psychological needs of the driver. Theimplementation of this workflow revealed different schemes of positiveexperiences during driver interaction in critical situations.

    Mobile application for speech quality measurement2012Independent thesis Basic level (degree of Bachelor), 10,5 poäng / 16 hpOppgave
    Abstract [en]

    This report describes a bachelor thesis in computer science performed at the system department within the product development unit for GSM (Global System for Mobile communication) at Ericsson in Linköping.GSM can be considered a mature technology but it is still updated with new features on a regular basis. This requires that the technology also continuously is being tested. One technique that is used to perform quality tests is called PESQ (Perceptual Evaluation of Speech Quality). PESQ is a standardized algorithm to perform speech quality tests; it gives a score based on how a human would percept speech quality.The purpose of this thesis was to enhance the speech quality analysis process used when testing the GSM network. One goal was to analyze if it was possible to record and inject sound into a phone call and verify the possibility to execute the PESQ algorithm using a smartphone. Another goal was to develop a smartphone application to perform the described tasks.In order to do so an application for Android was developed. The development process included an investigation whether the Android platform supplies the functionality required. The investiga-tion showed that no general solution for recording and injecting audio into a phone call could be found. Recording was possible on some smartphones, but the characteristics of the recorded audio were not as desired. No solution for injecting audio into a phone call could be found for any of the tested smartphones.However, even though no solution for recording and injecting was found, an application was developed. The application was decided to be more of a proof of concept on how an application of this kind would work. It would also be a good foundation for future development. Suggested future work in order to integrate the application into the existing testing environment is to find alternative solutions for recording and injecting, maybe with the help of smartphone manu-facturers.

    Abstract [en]

    As people read more and longer texts on the web, the simple formatting options that exists in todays browsers creates worse results than necessary. On behalf of Opera Software in Linköping, a better algorithm has been implemented in Javascript with the purpose of delivering a visually better experience for the reader. The implementation is first and foremost for mobile devices and therefore a large part of the thesis has been the evaluation and optimization of performance.

    Distributed User Interfaces for the Web2017Independent thesis Basic level (degree of Bachelor), 10,5 poäng / 16 hpOppgave
    Abstract [en]

    New ways of interaction between users and their computing devices has revealed that users are not only interested in sharing their data, but their user interfaces as well. This calls for an extension of the traditional notion of user interfaces, to a notion where user interfaces span over multiple devices: Distributed User Interfaces (DUIs). The purpose of this thesis is to identify challenges in developing Web based DUIs, and the result is a JavaScript library that aids the development of these types of interfaces. The development has been driven in an explorative fashion, to discover techniques that is appropriate to use, when moving ideas from existing DUI frameworks for the desktop, to the Web. Soundness of the implementation has been evaluated by measuring properties of the library source code that indicates maintainability and extensibility. The conclusion is that the library has the potential of answering the needs for future DUI development targeting the Web.

    Methods for developing visualizations in a non-designer environment: A case study2019Independent thesis Basic level (degree of Bachelor), 10,5 poäng / 16 hpOppgave
    Abstract [en]

    Teams consisting of only software developers will occasionally need to develop products that has to be easy to use. User Centered Design (UCD) is one approach to help increase the ease of use of a product and that can be incorporated into the teams’ traditional workflow when needed. The software developer team followed in this thesis had not tried to incorporate UCD into their current workflow when developing such products. So, this thesis looks at how a product designed with an agile/UCD approach differs from a product developed by the software development team’s traditional approach. The two products were designed to solve the same problem. The results show that the product developed with an agile/UCD-approach gave better usability rankings and better external appeal than the one created with the team’s traditional approach. On the other hand, traditional methods constitute a better choice for quick development of products for more technical user groups within the company for example.

    Abstract [sv]

    Denna studie har som syfte att ta fram ett designförslag på ett ögonrörelsestyrt infotainment-system samt utvärdera detta. Fokusen ligger på den funktionella design och dess för- och nackdelar. Studien tar upp tre olika designförslag varav ett valdes att göra en prototyp av. Prototypen skapades med hjälp av HTML5, Javascript och Python. Detta kopplades sedan samman med ett ögonrörelsesystem tillhörande Smart Eye AB. Prototypen användartestades och utvärderades med hjälp av en bilsimulator. Utvärderingen gjordes med hjälp av en enkät samt SUS-formulär. Enkäten resulterade i en kvalitativ utvärdering av prototypen medan SUS-värdet (69,88) pekar på att förbättringar bör göras för att öka den upplevda användbarheten. Studien innehåller även framtida förbättringsförslag för vidare utveckling.

    Interactive Analytics and Visualization for Data Driven Calculation of Individualized COPD Risk2018Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    Chronic obstructive pulmonary disease (COPD) is a high mortality disease, second to stroke and ischemic heart disease. This non-curable disease progressively exacerbates, leading to high personal and societal economic impact, reduced quality of life and often death. General treatment plans for COPD risk mistreating the individuals’ condition. To be effective, the treatment should be individualized following the practices of precision medicine. The aim of this thesis was to develop a data driven algorithm and system with visualization to assess individual COPD risk. With MRI body composition profile measurements, it is possible to accurately assess propensity of a multitude of metabolic conditions, such as coronary heart disease and type 2 diabetes.  The algorithm and system has been developed using Wolfram Language and R within the Wolfram Mathematica framework. The algorithm calculates individualized virtual control groups metabolically similar to the patient’s body composition and spirometric profile. Using UK Biobank data, our tool was used to assess patient COPD propensity using an individual-specific virtual control group with AUROC 0.778 (female) and 0.758 (men). Additionally, the tool was used to identify new body composition profiles related to COPD and associated comorbid conditions.

    Unmanned Aerial Vehicles (UAVs) have been extensively studied the past years for various applications. In this work, we propose a Markov chain to model the movement of a single FAY deployed for data collection from remote sensors. Furthermore, we introduce a second Markov chain to model the irregularities of the UAVs movement when it is in transit. We investigate the impact of the distance of the FAV from the sensor on the success probability of information transmission. We provide numerical evaluation of the theoretical results.

    Grading in interaction design education using design practitioners conceptions of process quality2012Inngår i: Interacting with computers, ISSN 0953-5438, E-ISSN 1873-7951, Vol. 24, nr 6, s. 472-481Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The designed product is often assessed in interaction design education, but there are also courses that focus on learning the design process. It is then necessary to develop criteria for grading in such courses. To make a successful transfer from theory to practice, students also need to learn the criteria practitioners use, rather than the criteria that academically oriented teachers use. To do this, one approach is to align criteria with the conceptions practicing interaction designers have of process quality in design. Therefore, the research questions for this study are what those conceptions are, and how they can be utilized in grading criteria for interaction design projects in education. Interviews were made with 10 interaction designers. The interviews were qualitatively analyzed. The results demonstrate that practicing interaction designers conceptualize the quality of the design process in three ways: it is good if established methods are used and the design is managed within resource constraints, and within organizational and technological limitations, while also meeting stated objectives; it is even better if the design has a thought-through rationale; and ideally, the design should also be inspirational. These conceptions were transferred to points on a criteria-referenced grading scale which was used to develop course specific grading criteria. The criteria were evaluated in terms of comprehensibility and reliability. The evaluation showed that most of the students who also attended lectures understood the criteria. A high and significant covariation and a high level of agreement between the two teachers who graded the projects were shown. Further, the developed criteria should be generalizable to other process-centered interaction design courses and to assessment in other design disciplines.

    Interaction and Service Design as Offering Perspectives in a Space of Action2014Inngår i: Proceedings of DRS 2014: Design's Big Debates / [ed] Youn-kyung Lim, Kristina Niedderer, Johan Redström, Erik Stolterman, Anna Valtonen, Umeå: Umeå Institute of Design, Umeå University , 2014, s. 7-15Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This paper makes the proposition that interaction and service design can be seen as offering perspectives in a space of action where acting agents grasp a finite perspective depending on objects of concern and equipment, and then reorganize the space. The meaning of this proposition is outlined in the paper, and it also presents a case study of client meetings at banks, which illustrates the proposition. That case show how equipment was used in the background while the clerk attended the client. The clerk made things available for the client in their shared region, directing the client’s perspective on the space of action. It was observed that equipment at times presented too rigid a perspective, not allowing the clerk to restructure it. Still, the clerk could make things available for himself or herself and for others, creating a multi-stable character of the region. Seeing interaction and service design in this way highlight the service moments as they appear to the individual agents who co-create the service throughout an encounter. The region set up by designers offers a frame of possible perspectives and an orientation in the service moment.

    Interaktionsdesign och UX: om att skapa en god användarupplevelse2014 (oppl. 1)Bok (Annet vitenskapelig)
    Abstract [sv]

    Interaktionsdesign och UX handlar om tekniker för att utforma nyskapande interaktiva produkter och tjänster med god användarupplevelse. God användarupplevelse, eller UX (eng. user experience), är det övergripande målet för designarbetet. Den här boken är tänkt som ett praktiskt stöd under hela designprocessen: från initiala insikter och formulerade avsikter, till konceptidéer och test av prototyper. Tyngdpunkten ligger på de tidiga faserna där designens inriktning slås fast.

    Boken vänder sig till yrkesverksamma som vill lära sig nya tekniker och arbetssätt, och till studenter som ska arbeta konkret med design av interaktiva produkter och tjänster.

    The Mediated Action Sheets: A Framework for the Fuzzy Front-End of Interaction and Service Design2013Inngår i: Crafting the Future: Proceedings of the 10th European Academy of Design Conference, 2013, s. 1-14Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The front-end of the design process is where the design work is framed for the first time. It is the early part of the design work where the design team decides what to design rather than how to design something. It is often referred to as fuzzy, since it is very tentative in nature and the design team has yet to develop a sense of direction. In product design, the team, however, already knows that they are to develop some kind of physical product. In graphic design, the team knows that some sort of visual artefact is to be produced. In interaction and service design, the design team has a wider scope, aiming to shape the activities people perform. The problem this paper addresses is what to focus on in the fuzzy front-end of interaction and service design. We propose using the Mediated Action Sheets, which provide a framework based on socio-cultural theories of mediated action to structure the user research and idea generation phases of the design process. The Mediated Action Sheets consist of The Persona Sheet that is a structure for user research and developing personas, and The Concept Design Sheet for thinking concept ideas through in more detail. The paper provides examples of how they can be incorporated into the craftsmanship of interaction and service design.

    A Service Walkthrough in Astrid Lindgren's Footsteps2012Inngår i: Proceedings from ServDes.2012 Conference Proceedings Co-Creating Services, The 3rd Service Design and Service Innovation Conference, 8-10 February, Espoo, Finland, Linköping: Linköping University Electronic Press, 2012, s. 21-29Konferansepaper (Fagfellevurdert)
    Abstract [en]

    How can service prototypes be created and evaluated? This paper describes how methods like bodystorming and experience prototyping can be used in combination with pluralistic walkthrough in an evaluation method we call ‘service walkthrough’. We put the method to test in the development of augmented tourism services at the author Astrid Lindgren's childhood home. After initial design work, a mock-up and roleplay of a treasure hunt in the garden of the childhood home was made. It was evaluated using the service walkthrough method. The most important lesson learned was that a service walkthrough can be used to evaluate service prototypes and that it reveals information about practical as well as experiential issues for users.

    Lifelogging in User Experience Research: Supporting Recall and Improving Data Richness2017Inngår i: Design journal, ISSN 1460-6925, E-ISSN 1756-3062, Vol. 20, s. S3954-S3965Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The purpose of lifelogging is to help users collect data for self-monitoring and reflection. We have in this study explored how lifelogging technology (a camera and a heart rate monitor) can change user experience (UX) research, and we describe a novel approach. Data was collected for three days with four participants, and a 4-6-hours co-creation workshop with stimulated recall interview was held with each of them to create an experience timeline. The timeline includes selfreported key experiences, lifelog stimulated experiences, heart rate, decisions, and valence. The results show that the number of experiences in the timeline that come from data points stimulated by the lifelogging, are as many as the self-reported data points. Lessons learned include that the use of lifelogging produces highly detailed UX research, but it is very time consuming, due to the sheer amount of data.

    Device-orientation is more engaging than drag (at least in mobile computing)2014Inngår i: NordiCHI '14 Proceedings of the 8th Nordic Conference on Human-Computer Interaction: Fun, Fast, Foundational, New York: ACM Press, 2014, s. 939-942Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Does device-orientation-based panning on mobile devices facilitate engagement? 20 users were asked to pan panoramas by turning around and changing the direction of the device, and by swiping with the finger on the touchscreen. The participants were also asked to rate how engaging they found it on the User Engagement Scale. It turned out that device-orientation-based panning was more engaging than drag-based panning. Moving your body to navigate information can pull you into an affective loop.

    Service Design Ways to Value-In-Use2016Inngår i: Service design geographies: Proceedings of the ServDes2016 Conference / [ed] Nicola Morelli, Amalia de Götzen, Francesco Grani, Linköping: Linköping University Electronic Press, 2016, Vol. 125, s. 530-536Konferansepaper (Fagfellevurdert)
    Abstract [en]

    What do we mean if we say that a service design work is an example of good design? This paper presents a provisional typology for the ways in which a service design proposal can contribute to value-in-use. The typology covers instrumentality, technical excellence, usefulness, social significance, mutual advantage, collective welfare, and aesthetic values. Moral implications related to norms, power structures and tensions between stakeholders are also considered. It is argued that the typology can facilitate service designers and researchers in framing and re-framing a design effort and conceptualise a value proposition.

    User Experience Qualities and the Use-Quality Prism2015Inngår i: The fuzzy front end of experience design: Workshop proceedings / [ed] Eija Kaasinen, Hannu Karvonen, Yichen Lu, Jari Varsaluoma, Heli Väätäjä, Espoo: VTT , 2015Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Deciding the desirable user experience qualities, i.e. UX goals, for a future product or service is important but difficult. This case study explores how a set of qualities is articulated in the concept design process. The case is a project aimed at exploring the use of smartphones to augment the childhood home of Astrid Lindgren—the children’s book author—with stories about her life and authorship. The results showed that articulated UX qualities focused the design work. It was also observed that one set of desirable qualities does not fit all phases in a project, and design consequences propagate between aspects of UX quality.

    Know thy users by interpretative phenomenological analysis2018Inngår i: Journal of Interaction Science, E-ISSN 2194-0827, Vol. 6, nr 3Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    One approach to getting to know a user and understanding the user experience (UX) is phenomenology. Currently, there is a lack of clearly defined methods for phenomenological analysis of user experience in design projects. Interpretative Phenomenological Analysis (IPA) is an approach developed in psychology, and in this article, it is adapted to the case of a pro bono design project at a UX design agency supporting a disadvantaged group of people, newly arrived immigrants to Sweden. The design project involved research on how the immigrants experienced a service that introduced them to the job market. The adapted method, UX IPA, contributed to the pro bono project with a focus on both experience and meaning, which is important in design projects that relate to major events in users’ lives. The method was considered less appropriate in UX projects for specific products with highly instrumental use. The method can, in many cases, be too costly. However, costs can possibly be reduced by top-down approaches. In commercial UX projects, the method may be appropriate for the fuzzy front-end of design and innovation, but clients may be unimpressed by the small sample size. This can potentially be alleviated by mixed-methods approaches.

    Transmodal interaction and user experience2016Inngår i: Proceedings of the 12'th SweCog Conference / [ed] Alexander Almér, Robert Lowe, Erik Billing, Skövde: The University of Skövde , 2016, s. 5-5Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    We are in a series of studies, ranging from news production to computer gaming, looking into the intersection of transmodal interaction and user experience. The purpose of this abstract is to outline the theoretical framework for that intersection. The first area we are studying is Transmodal Interaction, which is a concept that refer to a specific aspect of multimodal interaction. Human action is multimodal (Streeck, Goodwin, & LeBaron, 2011), and different sensory modes play an important role in action. However, little attention has been given to the intricate ways in which sensory modalities (seeing – drawing, hearing – saying, moving – touching, etc.) integrate, affect, and transform each other during the course of an activity. There are transformations of meaning in every new materialisation of an idea or a thought, partly depending on the communication potential of the sensory modality. This render what we refer to as a transmodal process where ideas and thoughts materialise action by action in an emergent sequence across relatively long and discontinuous timespans (Murphy, 2012). Over a sequence of actions, the meanings expressed in one modality, dynamically blend and shape what is expressed in other modalities. This produces, according to (Murphy, 2012) “a series of semiotic modulations in which certain core qualities persist, but others are noticeably transformed in the transition from one mode to another. (p. 1969)” We can, in intersemiotic translation (Jakobson, 1959) between modalities, address what is lost, how we introduce distortions, or even introduce perceptions of things that do not exist. A question is then how continuity of meaning and experience is preserved in modality changes. The second area we are studying is User Experience. The term refers to a person's perceptions and responses resulting from the use and/or anticipated use of a product, system or service (ISO, 2010). We employ a three level model of user experience based on Leontiev’s account of consciousness (Kaptelinin & Nardi, 2012; Leont ́ev, 1978), which also relate closely to Norman’s model of emotional design (Norman, 2005). The first level is the sensory fabric of consciousness, Norman refers to this as the visceral level. It is the largely subconscious level of how things feel. The second level is the personal meaning of things, related to what and how we do things action by action. Norman (ibid.) refers to this level as the behavioural level. The third level has to do with meaning, and what Norman refers to as a reflective level. It is the level of cultural meaning and what things mean for us in our socially and historically rooted activities. The intersection of these two areas constitutes our current focus of research. We are, in domains as different as news production and computer gaming, investigating persons’ perceptions and actions resulting from interaction with each other and with materialisations across different sensory modalities that give rise to intersemiotic translation effects.
