    The shared priorities measure as a way of assessing team strategic awareness – a bridge between self-assessment and the deep blue sea of field recordings2014In: ECCE '14 Proceedings of the 2014 European Conference on Cognitive Ergonomics / [ed] Stary, Christian, ACM Press, 2014, no 13Conference paper (Refereed)
    Abstract [en]

    Objective, easy to use, easy to comprehend, high face- validity assessment methods for measuring shared awareness in teams are hard to find. This paper describes an experiment where a new measure called Shared Priorities, which is based on ranking of self-generated strategic items, is tested. Trained teams were compared to non-trained teams in a dynamic problem-solving task in terms of performance and shared awareness. The shared priorities measure was used alongside other, well-documented measures of team awareness based on self-rating. The results show that the Shared Priorities measure correlate with performance and could also distinguish between trained and non-trained teams. However, the Shared Priorities measure did not correlate with the other team measures, suggesting that it captures a different quality of team work than the self-rating measures. Further, the shared priorities measure was found to be easily administered and gained a high user acceptance.

    Statistical modelling of team training in a microworld study2014In: Proceedings of the Human Factors and Ergonomics Society Annual Meeting, Sage Publications, 2014, Vol. 58, p. 894-898Conference paper (Refereed)
    Abstract [en]

    A command and control environment is a dynamic and complex setting with complicated technical systems where teams of operators interact to reach shared goals. This study presents an experiment in which we, by means of Structural Equation Modeling (SEM), explain the relations between basic concepts of command and control environments: mental workload, frustration, situational awareness, and performance. This paper reports a LISREL analysis of the Baroutsi, Berggren, Nählinder, & Johansson (2013) data. From that data, a new latent variable “Frustration” emerges, which now can be included in the model.

    Knowledge Carrying and Knowledge Emphasizing Animations: A Useful Distincitions when Developing Educational Software2008In: Proceedings of World Conference on Educational Multimedia, Hypermedia and Telecommunications 2008 / [ed] Joseph Luca & Edgar R. Weippl, Chesapeake, VA: AACE , 2008, p. 1228-1233Conference paper (Refereed)
    Abstract [en]

    Previous research on the usefulness of animations in educational software has not shown any unequivocal advantage of animations. We claim that these conflicting results at least in part stem from not distinguishing between different educational communicative uses of animations. We suggest that it is necessary to distinguish between knowledge carrying and knowledge emphasizing animations, and suggest guidelines for when animations can and cannot be used in educational software. We illustrate our analysis with examples from learners’ responses to educational software for the teaching of optics. Users not familiar with the field were found to have difficulties in understanding when the animation in itself is something to be learned from cases where the purpose of the animation is to draw the users’ attention to something that is to be learned. By adhering to the distinction above, we found no misunderstandings from our users regarding the purpose of the animations.

    Representations of discourse: cognitive and computational aspects1991Doctoral thesis, monograph (Other academic)
    Abstract [en]

    This work is concerned with empirical studies of cognitive and computational aspects of discourse representations. A more specific aim is to contribute to the development of natural language interfaces for interaction with computers, especially the development of representations making possible a continuous interactive dialogue between user and system.

    General issues concerning the relationship between human cognitive and computational aspects of discourse representations are studied through an empirical and theoretical analysis of a psychological theory of discourse coherence, the theory of mental models. The analysis suggests that there are principled limits to what workers in computational linguistics can learn from psychological work on discourse processing.

    As far as the theory of mental models as a psychologica1 theory of discourse is concerned, the effect of previous background knowledge of the domain of discourse on the processing of the types of texts often used in previous work is demonstrated. It is argued that this demonstration does not invalidate any of the basic assumptions of the theory, but should rather be seen as a modification or clarification. An attempt is also made to study the possible existence of different cognitive strategies used by different subjects and in different tasks.While some supporting evidence for this can be seen, it is argued that the results-obtained are not conclusive on this issue.

    Another set of studies use the so-called Wizard-of-Oz method, i.e. dialogues with simulated natural language interfaces. Here the focus of the analysis is on the dialogue structure, and on the use of referring and co-referring expressions in the dialogues. The basic result of thedialogue analysis is that it is possible to describe these kinds of dialogues using a dialogue grammar, the LINDA-model, the basic feature of which is the partitioning of dialogues in a number of initiative-response (IR) units. The study of referring expressions also shows a lack of some of the complexities encountered in human dialogues. The results point to the possibility of using computationally simpler methods than what has hitherto been assumed, both for the dialogue management and for the resolution of anaphoric references.

    Distributed Remembering Through Active Structuring of Activities and Environments2013In: Review of Philosophy and Psychology, ISSN 1878-5158, E-ISSN 1878-5166, Vol. 4, no 1, p. 153-165Article in journal (Refereed)
    Abstract [en]

    In this paper, we consider a few actual cases of mnemonic strategies among older subjects (older than 65). The cases are taken from an ethnographic study, examining how elderly adults cope with cognitive decline. We believe that these cases illustrate that the process of remembering in many cases involve a complex distributed web of processes involving both internal or intracranial and external sources. Our cases illustrate that the nature of distributed remembering is shaped by and subordinated to the dynamic characteristics of the on-going activity and to our minds suggest that research on memory and distributed cognition should focus on the process of remembering through detailed descriptions and analysis of naturally occurring situations.

    Two ways of grounding the discussion on extended cognition2011In: Expanding the Space of Cognitive Science: Proceedings of the 33rd Annual Meeting of theCognitive Science Society / [ed] Laura Carlson, Christoph Hoelscher, Thomas F. Shipley, Cognitive Science Society, Inc., 2011, p. 2347-2352Conference paper (Refereed)
    Abstract [en]

    We question two of the basic foundations of the Extended Mind hypothesis originally formulated by Clark and Chalmers, i.e. that all cognition is organism centered and that the important theoretical issues that the debate surrounding the Extended Mind hypothesis can fruitfully be resolved by to a large extent rely on invented examples of cognitive activities as the empirical foundation. We suggest that one way to proceed is to frame the hypothesis within the larger theoretical framework of activity theory, and another is to conduct extensive field studies of extended cognitive processes. We illustrate our position with examples of how these can be used to reformulate some of the aspects of the Extended Mind hypothesis.

    The Effect of a Geographical Information System on Communication in Professional Emergency Response Organizations2010In: ISCRAM 2010, 7th International Conference on Information Systems for Crisis Response and Management, ISCRAM , 2010Conference paper (Refereed)
    Abstract [en]

    This paper describes the basic communication analysis performed in a research project with an ambition to investigate the impact of geographical information system (GIS) on crisis management organizations. The goal is to compare the communication between command and control teams that have access to a GIS with geographical position information (GPS) capability in its command post with teams that only have access to paper maps. The method used is controlled experiments using the C3Fire micro-world. A total of 108 professionals, forming 18 teams, participated in the study. The participating professionals were members of Swedish municipal crisis management organizations. The result shows that the communication pattern connected to giving orders have a different distribution depending on if the teams used GIS or paper maps. The result also shows that the communication volume is reduced if the teams use GIS.

    Driving with a Speech Interaction System: Effect of Personality on Performance and Attitude of Driver2014In: HUMAN-COMPUTER INTERACTION: ADVANCED INTERACTION MODALITIES AND TECHNIQUES, PT II, SPRINGER-VERLAG BERLIN , 2014, Vol. 8511, p. 417-428Conference paper (Refereed)
    Abstract [en]

    Personality has a huge effect on how we communicate and interact with others. This study is one in a series of three that investigates how a speech based in-car system matched with dominant and submissive drivers affects performance and attitude drivers. The study was conducted with 30 participants at Linkoping University in Sweden. Data show that using a voice that combines feature from submissive and dominant speech patterns work well for both dominant and submissive drivers. The voice showed the same performance gain as when matching car voice personality with personality of driver, without the negative attitude ratings associated with the submissive car voice found in previous studies. Drivers assessment of the car system show that even though both dominant and submissive drivers find the system helpful, dominant drivers find the system more annoying and more likely to turn the system off. Design implications of in-vehicle systems are discussed.

    I Can’t Hear You? Driver’s Interacting with Male or Female Voices in Native or Non-Native Language2011In: Universal Access in Human-Computer Interaction. Context Diversity, Part III, Springer Berlin/Heidelberg, 2011, p. 298-305Conference paper (Refereed)
    Abstract [en]

    Many vehicles today are equipped with navigation systems, and all of these systems use speech or a combination of speech and graphics to provide drivers with directions to their destinations. This study investigates the effect of gender of voice when providing driving instructions in English to drivers that are non-native speakers of English. In a 2(native/non-native) by 2(gender of voice) between participant study, 40 participants in age group 18-25 drove in a driving simulator for 25 minutes with navigation information system that gave drivers directions to a set destination. Results show that gender of voice did not affect native English speaking drivers. For non-native speakers, however, a female voice worked better for both female and male drivers. Non-native speakers consistently missed to act on navigational information give by the male voice. Design implications for voice systems are discussed.

    Impact of Voice Variation in Speech-Based In-Vehicle Systems on Attitude and Driving Behavior2009In: Human Factors and Ergonomics Society Europe Chapter (HFES), 2009Conference paper (Refereed)
    Abstract [en]

    Automobile manufacturers are making information systems available in all vehicles. Mostsystems are screen based, but increasingly systems are either hybrids (screen/speech) orspeech based. Speech systems in vehicles may have advantages over screen based in-vehiclesystems; literature suggests that speech can be less distracting than screen-based interactions.Nonetheless, using speech systems in the car also introduces social and attitudinal effects.Voices are not neutral! Voices carry socio-economic cues including indicators of gender, age,personality, emotional state, ethniticity, education and social status. Perception ofinformation presented by the voice is influenced by the perception of the voice demographics.This is further complicated by different individuals perceiving voices in different ways. A voicethat is seen as positive by one individual can be perceived negatively by another. We presentresults from a number of driving simulator studies of speech based in-vehicle systems. These studiesshow that speech based in-vehicle systems can affect drivers’ attitude and drivingperformance. Attitude and performance can be improved, but the effect of the voice can also proveharmful for driving behaviour and driving safety. This makes it important to include the voice as adesign parameter of speech-based in-vehicle systems.

    The effects of different voices for speech-based in-vehicle interfaces: Impact of young and old voices on driving performance and attitude2009In: Proceedings of the 10th Annual Conference of the International Speech Communication Association, INTERSPEECH 2009, 2009, p. 2795-2798Conference paper (Refereed)
    Abstract [en]

    This paper investigates how matching age of driver with age of voice in a conversational in-vehicle information system affects attitudes and performance. 36 participants from age groups, 55 -75 and 18 - 25, interacted with a conversational system with young or old voice in a driving simulator. Results show that all drivers rather communicated with a young than old voice in the car. This willingness to communicate had a detrimental effect on driving performance. It is hence important to carefully select voices, since voice properties can have enormous effects on driving safety. Clearly, one voice doesnt fit all.

    Distilling dialogues - A method using natural dialogue corpora for dialogue systems development2000In: Proceedings of 6th Applied Natural Language Processing Conference, Seattle, USA: Association for Computational Linguistics Stroudsburg , 2000, p. 44-51Conference paper (Refereed)
    Abstract [en]

    We report on a method for utilising corpora collected in natural settings. It is based on distilling (re-writing) natural dialogues to elicit the type of dialogue that would occur if one the dialogue participants was a computer instead of a human. The method is a complement to other means such as Wizard of Oz-studies and un-distilled natural dialogues. We present the distilling method and guidelines for distillation. We also illustrate how the method affects a corpus of dialogues and discuss the pros and cons of three approaches in different phases of dialogue systems development.

    Info Touch: An Explorative Multi-Touch Visualization Interface for Tagged Photo Collections2008In: NordiCHI '08 Proceedings of the 5th Nordic conference on Human-computer interaction: building bridges, 2008, p. 491-494Conference paper (Refereed)
    Abstract [en]

    We report on a design exploration into how a large multi-touchtabletop display can be used for information visualization. Wedesigned an interface where users explored a tagged photocollection by bi-manual manipulation of the collections’ tagcloud. User feedback showed that despite the availability ofmulti-touch most of the actual interactions were single-touch.However, some particular natural actions, such as grabbing thetag cloud and partitioning it into two parts, were often carriedwith both hands. Thus our user study indicates that multi-touchcan act as a useful complementary interaction method ininformation visualization interfaces.

    An Evaluation of Space Time Cube Representation of Spatiotemporal Patterns2009In: IEEE TRANSACTIONS ON VISUALIZATION AND COMPUTER GRAPHICS, ISSN 1077-2626, Vol. 15, no 4, p. 696-702Article in journal (Refereed)
    Abstract [en]

    Space time cube representation is an information visualization technique where spatiotemporal data points are mapped into a cube. Information visualization researchers have previously argued that space time cube representation is beneficial in revealing complex spatiotemporal patterns in a data set to users. The argument is based on the fact that both time and spatial information are displayed simultaneously to users, an effect difficult to achieve in other representations. However, to our knowledge the actual usefulness of space time cube representation in conveying complex spatiotemporal patterns to users has not been empirically validated. To fill this gap, we report on a between-subjects experiment comparing novice users error rates and response times when answering a set of questions using either space time cube or a baseline 2D representation. For some simple questions, the error rates were lower when using the baseline representation. For complex questions where the participants needed an overall understanding of the spatiotemporal structure of the data set, the space time cube representation resulted in on average twice as fast response times with no difference in error rates compared to the baseline. These results provide an empirical foundation for the hypothesis that space time cube representation benefits users analyzing complex spatiotemporal patterns.

    The effect of different delineator post configurations on driver speed in night-time traffic: A driving simulator study2014In: Accident Analysis and Prevention, ISSN 0001-4575, E-ISSN 1879-2057, Vol. 72, p. 341-350Article in journal (Refereed)
    Abstract [en]

    The aim of the study was to investigate how different delineator post configurations affect driver speed in night-time traffic. In addition, the potential speed effect of introducing a secondary task was investigated. The study was carried out in a car simulator on a road stretch including straight road sections as well as curves with different radii. Fourteen drivers participated in the study and the results show that absence of delineator posts leads to reduced speed. However, provided that there are delineator posts continuously present along the road, the overall driver speed is basically the same, regardless of the spacing between the delineator posts. The results also imply that to reduce driver speed in curves with small radius, using more compact spacing of posts in these curves as compared to in curves with a larger radius, could be a potential strategy. Additionally, the speed reducing effect of a secondary task was only prevailing where the task was initiated.

    The Role of Spoken Feedback in Experiencing Multimodal Interfaces as Human-like2003In: Proceedings of ICMI'03, Vancouver, Canada, 2003., 2003, p. 250-257Conference paper (Refereed)
    Abstract [en]

    If user interfaces should be made human-like vs. tool-like has been debated in the HCI field, and this debate affects the development of multimodal interfaces. However, little empirical study has been done to support either view so far. Even if there is evidence that humans interpret media as other humans, this does not mean that humans experience the interfaces as human-like. We studied how people experience a multimodal timetable system with varying degree of human-like spoken feedback in a Wizard-of-Oz study. The results showed that users' views and preferences lean significantly towards anthropomorphism after actually experiencing the multimodal timetable system. The more human-like the spoken feedback is the more participants preferred the system to be human-like. The results also showed that the users experience matched their preferences. This shows that in order to appreciate a human-like interface, the users have to experience it.

    A case study of factor influencing role improvisation in crisis response teams2013In: Cognition, Technology & Work, ISSN 1435-5558, E-ISSN 1435-5566, Vol. 15, no 1, p. 79-93Article in journal (Refereed)
    Abstract [en]

    Common characteristics of crisis situations are ambiguous and unplanned for events. The need for improvised roles can therefore be an imperative factor for the success of an operation. The aim of this study is to deepen the understanding of the processes taking place during improvised work ‘‘as it happens’’. A case study of a crisis management team at work is presented and provides an in-depth analysis of the information and communication flow of persons acting in improvised roles, including con- textual factors influencing the task at hand. The analysis suggests that three main factors lay behind decreased per- formance by the team when some of its members were forced to take on roles for which they lacked professional training; lack of language skills, lack of domain knowledge and insufficient organizational structure of the tasks. Based on the observations from this case study, we suggest three ways of improving a team’s performance and hence resil- ience when forced to improvise due to lack of personnel in one or more required competence areas. These are training to take on the responsibility for tasks or roles outside ones professional area of specialization, developing formal routines for changes in roles and tasks and developing and using tools and routines for information sharing.

    Maps in the Head and Maps in the Hand2012In: Proceedings of the 34th Annual Meeting of the Cognitive Science Society / [ed] Naomi Miyake, David Peebles, Richard P. Cooper, Cognitive Science Society 2012 , 2012, p. 2339-2344Conference paper (Other academic)
    Abstract [en]

    Using the perspective of situated cognition we studied how people interact with a physical map to help them navigate through an unfamiliar environment. The study used a mixture of cognitive ethnography and traditional experimental methods. We found that the difference between high and low performing navigators showed up in the speed they completed their task and also in the way they use maps. High performers plan routes using a survey method whereas low performers use a route strategy. We suggest that when people are given a task that does not match their cognitive style they try to transform the task to better suit their cognitive abilities and cognitive style.

    Proceedings of the 14th SweCog Conference: Linköping 2018, 11-12 October2018Conference proceedings (editor) (Refereed)
    Abstract [en]

    Welcome to SweCog 2018 in Linköping!

    This booklet contains the program and short papers for oral and poster presentations at SweCog 2018, this year’s edition of the annual conference of the Swedish Cognitive Science Society. Following the SweCog tradition and its aim to support networking among researchers in cognitive science and related areas, contributions cover a wide spectrum of research.

    A trend in recent years, also reflected in this year’s conference program, is an increasing number of contributions that deal with different types of autonomous technologies, such as social robots, virtual agents or automated vehicles, and in particular people’s interaction with such systems. This clearly is a growing research area of high societal relevance, where cognitive science - with its interdisciplinary and human-centered approach - can make significant contributions.

    We look forward to two exciting days in Linköping, and we thank the many people who have contributed to the organization of this year’s SweCog conference, in particular of course all authors and reviewers! The organization of SweCog 2018 has been supported by the Faculty of Arts and Sciences, the Department of Culture Communication (IKK), and the Department of Computer Information Science (IDA) at Linköpping University, as well as Cambio Healthcare Systems and Visual Sweden.

    3D Visualization as a Communicative Aid in Pharmaceutical Advice-Giving over Distance2011In: Journal of Medical Internet Research, ISSN 1438-8871, E-ISSN 1438-8871, Vol. 13, no 3Article in journal (Refereed)
    Abstract [en]

    Background: Medication misuse results in considerable problems for both patient and society. It is a complex problem with many contributing factors, including timely access to product information. less thanbrgreater than less thanbrgreater thanObjective: To investigate the value of 3-dimensional (3D) visualization paired with video conferencing as a tool for pharmaceutical advice over distance in terms of accessibility and ease of use for the advice seeker. less thanbrgreater than less thanbrgreater thanMethods: We created a Web-based communication service called AssistancePlus that allows an advisor to demonstrate the physical handling of a complex pharmaceutical product to an advice seeker with the aid of 3D visualization and audio/video conferencing. AssistancePlus was tested in 2 separate user studies performed in a usability lab, under realistic settings and emulating a real usage situation. In the first study, 10 pharmacy students were assisted by 2 advisors from the Swedish National Co-operation of Pharmacies call centre on the use of an asthma inhaler. The student-advisor interview sessions were filmed on video to qualitatively explore their experience of giving and receiving advice with the aid of 3D visualization. In the second study, 3 advisors from the same call centre instructed 23 participants recruited from the general public on the use of 2 products: (1) an insulin injection pen, and (2) a growth hormone injection syringe. First, participants received advice on one product in an audio-recorded telephone call and for the other product in a video-recorded AssistancePlus session (product order balanced). In conjunction with the AssistancePlus session, participants answered a questionnaire regarding accessibility, perceived expressiveness, and general usefulness of 3D visualization for advice-giving over distance compared with the telephone and were given a short interview focusing on their experience of the 3D features. less thanbrgreater than less thanbrgreater thanResults: In both studies, participants found the AssistancePlus service helpful in providing clear and exact instructions. In the second study, directly comparing AssistancePlus and the telephone, AssistancePlus was judged positively for ease of communication (P = .001), personal contact (P = .001), explanatory power (P andlt;.001), and efficiency (P andlt;.001). Participants in both studies said that they would welcome this type of service as an alternative to the telephone and to face-to-face interaction when a physical meeting is not possible or not convenient. However, although AssistancePlus was considered as easy to use as the telephone, they would choose AssistancePlus over the telephone only when the complexity of the question demanded the higher level of expressiveness it offers. For simpler questions, a simpler service was preferred. less thanbrgreater than less thanbrgreater thanConclusions: 3D visualization paired with video conferencing can be useful for advice-giving over distance, specifically for issues that require a higher level of communicative expressiveness than the telephone can offer. 3D-supported advice-giving can increase the range of issues that can be handled over distance and thus improve access to product information.
