    Situated cognition in clinical visualization: the role of transparency in GammaKnife neurosurgery planning.2009In: Artificial intelligence in medicine, ISSN 1873-2860, Vol. 46, no 2, p. 111-8Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: The aim of this study was to investigate how the clinical use of visualization technology can be advanced by the application of a situated cognition perspective. METHODS AND MATERIALS: The data were collected in the GammaKnife radiosurgery setting and analyzed using qualitative methods. Observations and in-depth interviews with neurosurgeons and physicists were performed at three clinics using the Leksell GammaKnife. RESULT: The users' ability to perform cognitive tasks was found to be reduced each time visualizations incongruent with the particular user's perception of clinical reality were used. The main issue here was a lack of transparency, i.e. a black box problem where machine representations "stood between" users and the cognitive tasks they wanted to perform. For neurosurgeons, transparency meant their previous experience from traditional surgery could be applied, i.e. that they were not forced to perform additional cognitive work. From the view of the physicists, on the other hand, the concept of transparency was associated with mathematical precision and avoiding creating a cognitive distance between basic patient data and what is experienced as clinical reality. The physicists approached clinical visualization technology as though it was a laboratory apparatus--one that required continual adjustment and assessment in order to "capture" a quantitative clinical reality. CONCLUSION: Designers of visualization technology need to compare the cognitive interpretations generated by the new visualization systems to conceptions generated during "traditional" clinical work. This means that the viewpoint of different clinical user groups involved in a given clinical task would have to be taken into account as well. A way forward would be to acknowledge that visualization is a socio-cognitive function that has practice-based antecedents and consequences, and to reconsider what analytical and scientific challenges this presents us with.

    The need for transparency and rationale in automated systems2006In: Interacting with computers, ISSN 0953-5438, E-ISSN 1873-7951, Vol. 18, no 5, p. 1070-1083Article in journal (Refereed)
    Abstract [en]

    As medical devices and information systems become increasingly complex, the issue of how to support users becomes more important. However, many current help systems are often ignored or found to be too complicated to use by clinicians. In this article, we suggest an approach that allows designers to think about user support and automating tasks in ways users find more acceptable. The issue we address in particular is the notion of transparency and to what extent it allows the end-user to understand and critique the advice given. We have found that one central problem with existing support systems is that often the end-user does not understand the differences between the automated parts and the parts that have to be done manually. By taking aspects of transparency and control into account when designing an automated tool it seems that some of the more refractory issues that help systems pose for professional users can be addressed. © 2006 Elsevier B.V.

    Adding value with 3D visualization and haptic forces to radiosurgery - A small theory-based, quasi-experimental study2006In: Journal of medical systems, ISSN 0148-5598, E-ISSN 1573-689X, Vol. 30, no 4, p. 293-301Article in journal (Refereed)
    Abstract [en]

    This study investigates the use of 3D representation and haptic technology in radiosurgery. The users, experienced users of the Leksell GammaKnife, prefer the 3D representation for constructing a first draft of their plan for neurosurgical intervention. When it comes to the final adjustments, however, they still choose the traditional 2D representation and interaction devices. The perceived control over the radiosurgical process is not considered adequate using the 3D interaction methods. Practitioners do not consider the haptic forces implemented in this test system useful. Possible explanations for these findings are discussed in the paper. © Springer Science+Business Media, Inc. 2006.

    Tools and Versioning for GUI text in SDP3: Rakesh Dronamraj2010Independent thesis Advanced level (degree of Master (Two Years)), 30 credits / 45 HE creditsStudent thesis
    Abstract [en]

    Scania, one of the heavy engines manufacturers, produces Scania Diagnos Programmer 3 (SDP3) to facilitate repair process in their workshops. SDP3 is localizable software which challenges to separate User Interface strings (UI strings) during development process and later combine with the localized strings for local user access. The objective of this report is to provide knowledgeable solution for Graphical User Interface (GUI) development, especially with respect to synchronization of UI strings in SDP3.The migration of SDP3 from .NET 3.0v framework to .NET 3.5v framework satisfies modern standards and needs. With regards to migration of SDP3’s localization process, I have attempted to summarize major .NET 3.5v framework methods that can be used for localization of GUI text in SDP3. Experiments show that tools used to facilitate the localization process also lack important features. Although pre-build process and post-build process provide promising solutions for localization, using them along with some proprietary localization tool should result in more features, better and faster production cycle. However, proprietary localization tool have to be used with anyone of the localization methods.

    Web 2.0 Systems Supporting Childhood Chronic Disease Management: Design Guidelines Based on Information Behaviour and Social Learning Theories2010In: JOURNAL OF MEDICAL SYSTEMS, ISSN 0148-5598, Vol. 34, no 2, p. 107-117Article in journal (Refereed)
    Abstract [en]

    Self-directed learning denotes that the individual is in command of what should be learned and why it is important. In this study, guidelines for the design of Web 2.0 systems for supporting diabetic adolescents every day learning needs are examined in light of theories about information behaviour and social learning. A Web 2.0 system was developed to support a community of practice and social learning structures were created to support building of relations between members on several levels in the community. The features of the system included access to participation in the culture of diabetes management practice, entry to information about the community and about what needs to be learned to be a full practitioner or respected member in the community, and free sharing of information, narratives and experience-based knowledge. After integration with the key elements derived from theories of information behaviour, a preliminary design guideline document was formulated.

    Impact of precautionary behaviors during outbreaks of pandemic influenza: modeling of regional differences2009In: AMIA ... Annual Symposium proceedings / AMIA Symposium. AMIA Symposium, ISSN 1942-597X, Vol. 2009, p. 163-167Article in journal (Refereed)
    Abstract [en]

    Using time geographic theory for representation of population mixing, we set out to analyze the relative impact from precautionary behaviors on outbreaks of pandemic influenza in Europe and Asia. We extended an existing simulator environment with behavioral parameters from a population survey to model different behaviors. We found that precautionary behaviors even among a minority of the population can have a decisive effect on the probability of the outbreak to propagate. The results also display that assumptions strongly influences the outcome. Depending on the interpretation of how many "children" are kept from "school", R(0) changes from a range where outbreak progression is possible to a range where it is improbable in both European (R(0)=1.77/1.23) and Asian (R(0)=1.70/1.05) conditions. We conclude that unprompted distancing can have a decisive effect on pandemic propagation. An important response strategy can be to promote voluntary precautionary behavior shown to reduce disease transmission.

    Transparency and documentation in simulations of infectious disease outbreaks: Towards evidence-based public health decisions and communications2009In: Proceedings of the Second International ICST Conference on Electronic Healthcare for the 21st century, 2009, p. 28-34Conference paper (Refereed)
    Abstract [en]

    Computer simulations have emerged as important tools in the preparation for outbreaks of infectious disease. To support the collaborative planning and responding to the outbreaks, reports from simulations need to be transparent (accessible) with regard to the underlying parametric settings. This paper presents a design for generation of simulation reports where the background settings used in the simulation models are automatically visualized. We extended the ontology-management system Protégé to tag different settings into categories, and included these in report generation in parallel to the simulation outcomes. The report generator takes advantage of an XSLT specification and collects the documentation of the particular simulation settings into abridged XMLs including also summarized results. We conclude that even though inclusion of critical background settings in reports may not increase the accuracy of infectious disease simulations, it can prevent misunderstandings and less than optimal public health decisions.

    The semantic-document approach to combining documents and ontologies2007In: International journal of human-computer studies, ISSN 1071-5819, E-ISSN 1095-9300, Vol. 65, no 7, p. 624-639Article in journal (Refereed)
    Abstract [en]

    An ontology is a powerful way of representing knowledge for multiple purposes. There are several ontology languages for describing concepts, properties, objects, and relationships. However, ontologies in information systems are not primarily written for human reading and communication among humans. For many business, government, and scientific purposes, written documents are the primary description and communication media for human knowledge communication. Unfortunately, there is a significant gap between knowledge expressed as textual documents and knowledge represented as ontologies. Semantic documents aim at combining documents and ontologies, and allowing users to access the knowledge in multiple ways. By adding annotations to electronic-document formats and including ontologies in electronic documents, it is possible to reconcile documents and ontologies, and to provide new services, such as ontology-based searches of large document databases. To accomplish this goal, semantic documents require tools that support both complex ontologies and advanced document formats. The Protégé ontology editor, together with a custom-tailored documentation-handling extension, enables developers to create semantic documents by linking preexisting documents to ontologies. © 2007 Elsevier Ltd.

    Abstract [en]

    The JessTab project contributes to the understanding of how ontology editors and performance systems can work together. This understanding includes the mapping from the Protege knowledge representation to the jess representation and the use of Jess definitions as system classes in Protege ontologies. The JessTab also supports the Jess community by allowing the use of Protege as an object-oriented extension to Jess and by providing a tool for using Protege as a graphical front end to Jess.

    Assumptions management in simulation of infectious disease outbreaks2009In: AMIA ... Annual Symposium proceedings / AMIA Symposium, ISSN 1942-597X, Vol. 2009, p. 173-177Article in journal (Refereed)
    Abstract [en]

    Simulation of outbreaks of infectious disease is an important tool for understanding the dynamics of the outbreak process, the impact of disease and population properties, and the potential effect of interventions. However, the interpretation of the simulation results requires a clear understanding of the assumptions made in the underlying model. Typical simulation tasks, such as exploring the space of different scenarios for population and disease properties, require multiple runs with varying model parameters. For such complex tasks, the management of the assumptions made becomes a daunting and potentially error-prone undertaking. We report explicit assumptions management as an approach to capture, model, and document the assumptions for simulator runs. It was found possible to extend ontology-based simulation, which uses an ontological model to parameterize the simulator, to incorporate an assumptions model in the ontology. We conclude that explicit assumptions modeling should be part of any infectious disease simulation architecture from start.

    Ontology based modeling of pandemic simulation2007In: MedINFO 2007,2007, IOS Press, 2007, p. 755-759Conference paper (Refereed)
    Abstract [en]

    Computer-based simulation of influenza outbreaks in local communities can help researchers, epidemiologists, and decision makers better understand the impact of the community structure on the reproduction rate of disease, and the relative benefits of different types of prevention and interventions. The goal of scenario modeling is to develop a description of scenario components, such us the disease, the community and interventions. An ontology-based representation of the scenario model together with a modeling tool, which is based on an extension to Protege assist scenario developers in formulating simulation specifications. This approach allows the exploration of new ideas by rapidly formulating and reconstructing scenarios from novel components.

    A Cloud-Based Simulation Architecture for Pandemic Influenza Simulation2011In: AMIA Annual Symposium Proceedings 2011, Curran , 2011, p. 364-373Conference paper (Refereed)
    Abstract [en]

    High-fidelity simulations of pandemic outbreaks are resource consuming. Cluster-based solutions have been suggested for executing such complex computations. We present a cloud-based simulation architecture that utilizes computing resources both locally available and dynamically rented online. The approach uses the Condor framework for job distribution and management of the Amazon Elastic Computing Cloud (EC2) as well as local resources. The architecture has a web-based user interface that allows users to monitor and control simulation execution. In a benchmark test, the best costadjusted performance was recorded for the EC2 H-CPU Medium instance, while a field trial showed that the job configuration had significant influence on the execution time and that the network capacity of the master node could become a bottleneck. We conclude that it is possible to develop a scalable simulation environment that uses cloud-based solutions, while providing an easy-to-use graphical user interface.

    The potential of smart homes for injury prevention among the elderly2002In: Injury control and safety promotion, ISSN 1566-0974, E-ISSN 1744-4985, Vol. 9, no 2, p. 127-131Article in journal (Refereed)
    Abstract [en]

    Smart homes promise to make the lives of elderly people more comfortable and safe. Today, there is a significant interest from industry and policy makers in developing these technologies. In theory, the emerging technologies make it possible to provide a new range of services. So far, however, the goal has often been to develop new services for young people rather than assisting old people to improve their quality of life. Especially important is the potential for using these technologies to promote safety and prevent injury among old people because this group is at home more than the other age groups. Networked devices can collect data from sensors and aid decision-making on intervention and other measures. Furthermore, these devices can instruct and remind individuals about safety-related issues.

    Developing a DUI Based Operator Control Station2011In: Distributed User Interfaces: Designing Interfaces for the Distributed Ecosystem / [ed] Jose A. Gallud, Ricardo Tesoriero, and Victor M.R. Penichet, Springer London, 2011, p. 41-49Chapter in book (Other academic)
    Abstract [en]

    Distributed User Interfaces (DUIs) provide new degrees of freedom to the distribution of systems. This work presents a seamless way for developers to handle the event communication structure much in the same way as in traditional applications. Our framework Marve is the externalization experience of developing several DUI systems. To evaluate our framework we developed a DUI system together with SAAB Aerosystem Human-Machine Interaction division. Using our approach to develop the sample application we show that the current model for development of UIs can be extended to incorporate support for DUI development

    The evolution of Protégé: An environment for knowledge-based systems development2003In: International journal of human-computer studies, ISSN 1071-5819, E-ISSN 1095-9300, Vol. 58, no 1, p. 89-123Article in journal (Refereed)
    Abstract [en]

    The Protégé project has come a long way since Mark Musen first built the Protégé meta-tool for knowledge-based systems in 1987. The original tool was a small application, aimed at building knowledge-acquisition tools for a few specialized programs in medical planning. From this initial tool, the Protégé system has evolved into a durable, extensible platform for knowledge-based systems development and research. The current version, Protégé-2000, can be run on a variety of platforms, supports customized user-interface extensions, incorporates the Open Knowledge-Base Connectivity (OKBC) knowledge model, interacts with standard storage formats such as relational databases, XML, and RDF, and has been used by hundreds of individuals and research groups. In this paper, we follow the evolution of the Protégé project through three distinct re-implementations. We describe our overall methodology, our design decisions, and the lessons we have learned over the duration of the project. We believe that our success is one of infrastructure: Protégé is a flexible, well-supported, and robust development environment. Using Protégé, developers and domain experts can easily build effective knowledge-based systems, and researchers can explore ideas in a variety of knowledge-based domains. © 2002 Elsevier Science Ltd.

    Design of interactive health drama built on social realism.2004In: MedInfo, IOS Publishing , 2004, Vol. 11, no Pt 2, p. 879-883Conference paper (Refereed)
    Abstract [en]

    There are many psychosocial aspects of chronic diseases, such as diabetes. Educational multimedia can support patients with chronic diseases and their families by communicating narratives based on social realism. The production of such socio-realistic interactive health dramas requires systematic methods, especially for the identification of significant stories. The aim of this study is to explore the use of self-documentary video in the design of an Interactive Health Drama environment to support diabetic adolescents and their families. In particular, the potential of the self-documentary video for story development in combination with qualitative interviews were explored. The proposed approach, when further developed, is intended to enable all types of chronic disease patients to work with their specific psychosocial problems in a supportive and stimulating environment adapted to their personality and preferences.

Proceedings / [ed] Wijnand A. IJsselsteijn, Yvonne A.W. de Kort, Cees Midden, Berry Eggen and Elise van den Hoven, Springer Berlin/Heidelberg, 2006, p. 167-170Chapter in book (Refereed)
    Abstract [en]

    Heating is a significant expenditure of many households today but the actual power consumption of the heating devices are seldom recognized. To help people understand and reflect upon their domestic energy consumption, we have designed an electrical radiator that emits heat entirely from light bulbs. This appliance responds to temperature changes in the room via sensors. The idea was to combine the product semantics of lamps and radiators and direct focus on the latter neglected product category. We argue that by re-designing domestic appliances adding means to visualize energy consumption in engaging and interesting ways it is possible to make energy utilization less abstract and easier to comprehend.

    Towards second-generation smart card-based authentication in health information systems: the secure server model.2001In: Medinfo, ISSN 1569-6332, Vol. 10, no Pt 2, p. 1257-1261Article in journal (Refereed)
    Abstract [en]

    Conventional smart card-based authentication systems used in health care alleviate some of the security issues in user and system authentication. Existing models still do not cover all security aspects. To enable new protective measures to be developed, an extended model of the authentication process is presented. This model includes a new entity referred to as secure server. Assuming a secure server, a method where the smart card is aware of the status of the terminal integrity verification becomes feasible. The card can then act upon this knowledge and restrict the exposure of sensitive information to the terminal as required in order to minimize the risks. The secure server model can be used to illuminate the weaknesses of current approaches and the need for extensions which alleviate the resulting risks.

    The medical software quality deployment method1999In: Methods of Information in Medicine, ISSN 0026-1270, Vol. 38, no 1, p. 66-73Article in journal (Refereed)
    Abstract [en]

    The objective of this study was to develop a Quality Function Deployment (QFD) model for design of information systems in health-care environments. Consecutive blocked-subject case studies were conducted, based on action research methods. RESULTS: Starting with a QFD model for software development, a model for information system design, the Medical Software Quality Deployment (MSQD) model, was developed. The MSQD model was divided into the pre-study phase, in which the customer categories and their power to influence the design are determined; the data collection phase, in which the voice of customers (VoC) is identified by observations and interviews and quantified by Critical. Incident questionnaires; the need specification phase, where the VoC is specified into ranked customer needs; and the design phase where the customer needs are transformed stepwise to technical requirements and design attributes. QFD showed to be useful for integrating the values of different customer categories in software development for health-care settings. In the later design phases, other quality methods should be used for software implementation and testing.

    A blueprint for using commercial games off the shelf in defence training, education and research simulations2006Licentiate thesis, monograph (Other academic)
    Abstract [en]

    There are two types of simulations, those made for business and those made for pleasure. The underlying technology is usually the same, the difference being how and for what purpose the simulation is used. Often the two purposes can be combined. Nowhere is this more obvious than in the mutual benefit that exists between the military community and the entertainment business. These mutual benefits have only in recent years begun to be seriously explored.

    The objective of this work is to explore how to modify and use commercial video games off the shelf, in defence training, education and research. The work focuses on the process of how and what to consider when modifying commercial off the shelf games for military needs.

    The outlined blueprint is based on studies performed with combatants from the Swedish Army. To facilitate the develop­ment of the blueprint, a great number of commercial games used by military communities around the world are evaluated. These evaluations, in harmony with literature in the area, are used to develop a basic theoretical framework. The basic theoretical framework characterizes the approach and style throughout the work.

    From a general point of view, there are two overall findings; first there is an urgent need for more intuitive, pedagogical and powerful tools for preparation, management and evaluation of game-based simulation, especially since the real learning often takes place during the modification process rather the during the playing session. Second, there is a defective understanding of the differences between and purposes of a defence simulation and a game. Defence simulations focus on actions and events, while video games focus on human reactions to actions and events.

    Use of cultural probes for representation of chronic disease experience: Exploration of an innovative method for design of supportive technologies2005In: Technology and Health Care, ISSN 0928-7329, Vol. 13, no 2, p. 87-95Article in journal (Refereed)
    Abstract [en]

    Chronic diseases do not only manifest themselves as sets of pathophysiological factors. They bring about an equally important psychosocial impact. Unfortunately, it is difficult to account for this impact in the development of supportive technologies. This study describes and explores a method for elicitation of requirements on technologies supporting self-management including emotional aspects. The method takes advantage of a self-documentary media kit for collection of data from the everyday context of chronic disease. The resulting contextual data can contribute new insights to multi-disciplinary teams in the design of supporting technologies.

    Design perspectives2006In: Human-Computer Interaction, ISSN 0737-0024, E-ISSN 1532-7051, Vol. 21, no 1Article in journal (Refereed)
    Abstract [en]

    In this article we argue that a structured use of perspective descriptions can support a design process. A design perspective is a coherent set of values and aspects emphasized by the designer in a given design situation. We present a generic framework for describing 7 dimensions of perspectives concerning user, artifact, context, activities, communication, central relations, and use qualities that we argue are relevant in a design situation. Subsequently we use this metaperspective to describe four perspectives: tool, architectural, usability, and media perspective distilled from literature sources. By conducting two design workshops, we have evaluated the effects of using perspective descriptions to address the problem of idea generation in the early phases of design. Our analysis shows that the perspectives contain values that can have an important impact on the resulting artifact. By guiding the exploration of the design space, they influence both the artifact's conceptual idea and its use qualities. In our design example, a car game, the conceptual idea of the artifact varied from a goal-oriented tool to a media-based communication experience. Use qualities varied from a task-based flow of action to a format-dependent communication experience. The perspectives served as a synthesis of basic assumptions from the literature and as support to generate conceptually different design ideas. Based on the outcome of our study, we propose an approach for working with design perspectives in design practice, and education. We also present an agenda for research on design perspectives.

    Modeling Human Activities for Service Discovery in Pervasive Computing: The Magubi Approach2008In: ICPCA,2008, Piscataway, New Jersey, USA: IEEE Conference Publications Management Group , 2008, p. 735-740Conference paper (Refereed)
    Abstract [en]

    Service discovery is an important part of pervasive computing. Present mainstream service discovery protocols are to a high degree focused on the immediate properties of services and devices, as well as ensuring a high degree of connectivity. As the amount of discovered available services and devices go up, the challenge becomes how to ensure that systems and humans find relevant services, without overloading the systems or humans. Magubi is a model and implementation that is able to not only do advanced standard service discovery, but also, by viewing human tasks and activities as services, is able to expand the realm of service discovery for pervasive computing while addressing the overload challenge. Here, we present the model, and how we model services, humans, and activities. By taking the magubi-approach, service discovery also becomes proactive and is able to assist in a wide range of human endeavors.

    Modelling User Tasks and Intentions for Service Discovery in Ubiquitous Computing2007Licentiate thesis, monograph (Other academic)
    Abstract [en]

    Ubiquitous computing (Ubicomp) increases in proliferation. Multiple and ever growing in numbers, computational devices are now at the users' disposal throughout the physical environment, while simultaneously being effectively invisible. Consequently, a significant challenge is service discovery. Services may for instance be physical, such as printing a document, or virtual, such as communicating information. The existing solutions, such as Bluetooth and UPnP, address part of the issue, specifically low-level physical interconnectivity. Still absent are solutions for high-level challenges, such as connecting users with appropriate services. In order to provide appropriate service offerings, service discovery in Ubicomp must take the users' context, tasks, goals, intentions, and available resources into consideration. It is possible to divide the high-level service-discovery issue into two parts; inadequate service models, and insufficient common-sense models of human activities.

    This thesis contributes to service discovery in Ubicomp, by arguing that in order to meet these high-level challenges, a new layer is required. Furthermore, the thesis presents a prototype implementation of this new service-discovery architecture and model. The architecture consists of hardware, ontology-layer, and common-sense-layer. This work addresses the ontology and common-sense layers. Subsequently, implementation is divided into two parts; Oden and Magubi. Oden addresses the issue of inadequate service models through a combination of service-ontologies in concert with logical reasoning engines, and Magubi addresses the issue of insufficient common-sense models of human activities, by using common sense models in combination with rule engines. The synthesis of these two stages enables the system to reason about services, devices, and user expectations, as well as to make suitable connections to satisfy the users' overall goal.

    Designing common-sense models and service ontologies for a Ubicomp environment is a non-trivial task. Despite this, we believe that if correctly done, it might be possible to reuse at least part of the knowledge in different situations. With the ability to reason about services and human activities it is possible to decide if, how, and where to present the services to the users. The solution is intended to off-load users in diverse Ubicomp environments as well as provide a more relevant service discovery.
