    Exploring user contexts - a qualitative study of everyday activities2004Rapport (Övrigt vetenskapligt)
    Abstract [en]

    The physical, social, and computational context of people affect their choice of activity, thus also their need for and use of mobile services. It is quite easy to find likely examples of situations where this would be true. For example, a person who is standing on a subway station on the way home from work, waiting for a train that does not appear to be on time, is more likely to feel a need for a subway time table or traffic information than someone who is driving a car. To what degree does context matter is however not easy to answer precisely. Which context parameters matter for which activities, and in which combinations? This report describes a study with the aim to draw a map of user activities and context parameters, as well as combinations of context parameters. The study is based on a qualitative method with only 10 study participants, and thus, no precise answers can be given to any question regarding which context parameters matter more than others when trying to predict what user activity is needed the most for every given situation. However, the intention is that the report will assist in determining which context parameters and user activities are the most interesting to take a closer look at.

    Exploring the importance of context parameters for service use in everyday situations2004Rapport (Övrigt vetenskapligt)
    Abstract [en]

    The work described herein focus on the impact of different context factors in short-term planning situations. We have investigated which services have been used to solve different tasks. The method used in the study was based on scenario descriptions. The participants reported how they would have acted in different situations and they also rated the importance of different context factors in different situations. Analyses were made that revealed relationships between context factors and services used by the participants of the study. A qualitative analysis was also conducted, with the aim to capture context factors not covered in the study design.

    Using VR to improve the design of assembly tasks and increase task efficiency2018Ingår i: Proceedings of NordDesign: Design in the Era of Digitalization, NordDesign 2018, 2018Konferensbidrag (Refereegranskat)
    Abstract [en]

    In this paper we discuss how theories of vision, touch, sound, and learning behavior can form a basis for the development of a testbed through which real-life task performance can be compared with task performance in a Virtual Reality (VR) environment. By taking a multisensory approach, it will be possible to simulate the functionalities of a real training setting in a VR environment. Approaching this problem from a theoretical perspective, we will view it from a new angle and discuss whether we can enhance and nuance feedback in the virtual experience through the use of ambient media like sound, scent, heat, and wind. Sound may hold a great potential here. For visual perception, it is not only crucial that we can see relationships but that we are also able to search for patterns that we recognize. If an object is taken outside its context, its meaning can easily shift. To see is to search for patterns, but vision is also dependent on our experience of other senses. We can imagine how a given surface might feel by looking at a representation of the object, and this is because of previous tactile experiences with similar objects. From a technical perspective, integrating sound in a virtual environment is a straightforward process. Research shows that the process of learning a series of physical actions can be enhanced when it occurs in parallel with verbal or written information. In the literature, this phenomenon is described in terms of enactment or subject-performed tasks. Based on theories regarding vision, touch, sound and learning behavior, we suggest the design of a testbed that can be used in a pilot study aimed at increasing knowledge on how VR and AR can support learning in an assembly or installation context in order to produce guidelines for such an environment.

    Spatial or narrative: a study of the Agneta and Frida system1999Konferensbidrag (Refereegranskat)
    Abstract [en]

    We propose that analysing interviews with subjects who have been exposed to anthropomorphic characters from a metaphorical point of view can provide insights into how characters in the interface are perceived. In a study of the Agneta & Frida system (two characters that comment contents of web pages in an ironic, humorous manner) we found that subjects who used Agneta & Frida used more narrative verbs and adverbs than users who only browsed the web pages. In the latter case, more spatial verbs and adverbs were used. This may imply that normal web browsing is perceived as navigation through a space, while Agneta & Frida provides for a more narrative experience.

    Individual Differences and Navigation in Hypermedia1996Rapport (Övrigt vetenskapligt)
    Abstract [en]

    This study derives from two important observations. First, that navigation in hypermedia is a difficult task, and second, that individual cognitive differences play a role in how well users are able to efficiently use computer systems. We found that of the cognitive abilities tested in our study, only spatial ability could be related to the time spent in completing a set of tasks in a large, hypermedia, information structure. We furthermore found that it was only certain aspects of spatial ability which were related to the ability navigate in hypermedia, namely those related to solving spatial problems mentally rather than solving spatial problems in the physical world.

    To capture the diverse needs of welfare technology stakeholders – Evaluation of a value matrix2017Ingår i: Third International Conference, ITAP 2017, Held as Part of HCI International 2017, Vancouver, BC, Canada, July 9-14, 2017: Proceedings, Part II, Springer, 2017, 404-419 s., 2017, s. 404-419Konferensbidrag (Refereegranskat)
    Abstract [en]

    Welfare technology (WT) is often developed with a technical perspective, which does not involve important ethical considerations and different values that come up during the development and implementation of WT within elderly care. This paper presents a study where we have applied an ethical value matrix to support systematic ethical assessments of WT intended for personal health monitoring. The matrix consists of values in a checklist and a number of stakeholders and it is possible to analyze which values are emphasized by which stakeholders. The aim was to assess the matrix and find out how the matrix supports identification of values and interests that drive the various stakeholders in the development and implementation of WT. We have realized that several values specified by different actors as especially important were not included in the matrix and that the values in the matrix did not visualize or enable identification of value conflicts.

    A user-centered ethical assessment of welfare technology for elderly2018Ingår i: Lect. Notes Comput. Sci., 2018, s. 59-73Konferensbidrag (Refereegranskat)
    Abstract [en]

    Welfare technology (WT) is often developed with a technical perspective, and little consideration is taken regarding the involvement of important ethical considerations and different values that come up during the development and implementation of WT. Safety, security and privacy are significant, as well as the usability and overall benefit of the tool, but to date assessments often lack a holistic picture of the WT as seen by the users. This paper suggests a user-centered ethical assessment (UCEA) framework for WT to be able to evaluate ethical consequences as a part of the user-centered aspects. Building on established methodologies from research on ethical considerations, as well as the research domain of human-computer interaction, this assessment framework joins knowledge of ethical consequences with aspects affecting the “digitalization with the individual in the center”, e.g. privacy, safety, well-being, dignity, empowerment and usability. The framework was applied during development of an interface for providing symptom information to Parkinson patients. The results showed that the UCEA framework directs the attention to values emphasized by the patients. Thus, functionality of the system was evaluated in the light of values and expected results of the patients, thereby facilitating follow-up of a user-centered assessment. The framework may be further developed and tested, but in this study it served as a working tool for assessing ethical consequences of WT as a part of user-centered aspects.

    On the design of television as a service based on average TV watching2010Rapport (Övrigt vetenskapligt)
    Abstract [en]

    Ten households were interviewed about their TV watching to inform the design of TV services. Our participants were average TV viewers who had Internet access but were not technically advanced or frequent users of the Internet as a source for TV material. We found that the flow of programs that broadcast television brings to viewers was the most important motivation for our participants to turn to the TV on-demand possibilities they had access to. Examples of triggers were social cues from people talking about things seen on TV, or time-shifting issues such as missing all or part of programs in the broadcast flow. Special interests such as sports were also a strong motivation for on-demand behavior. For the viewers, linear and on-demand TV watching was intertwined. We conclude that on-demand services should be integrated with broadcast TV in the design of future TV services.

    Live Broadcasting – The Feeling of Presence and Social Interaction2011Konferensbidrag (Refereegranskat)
    Abstract [en]

    This paper describes user-related aspects in the deployment of a live broadcasting service. Four user studies were conducted, addressing different user groups and different research questions. Participating user groups were the production team that generated content for live broadcasts and the viewers of the broadcasts. The aim of the studies was to investigate to which extent quality affects the experience and which functionality is needed to convey a feeling of presence. Technology and functionality needs were studied regarding the production team. The results showed the importance of a production environment that is easy to use, and providing the opportunity for producers to use the technology in their own creative way. The results related to the viewers supported the assumption that it was important to create a feeling of presence for those watching the matches via the service. Finally, the user groups also had several suggestions for functionalities that could increase the social interaction and feeling of presence.

    An interactive distance solution for stroke rehabilitation in the home setting–A feasibility study2017Ingår i: Informatics for Health and Social Care, ISSN 1753-8157, E-ISSN 1753-8165, Vol. 42, nr 3, s. 303-320Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: In this study an interactive distance solution (called the DISKO tool) was developed to enable home-based motor training after stroke. Objectives: The overall aim was to explore the feasibility and safety of using the DISKO-tool, customized for interactive stroke rehabilitation in the home setting, in different rehabilitation phases after stroke. Methods: Fifteen patients in three different stages in the continuum of rehabilitation after stroke participated in a home-based training program using the DISKO-tool. The program included 15 training sessions with recurrent follow-ups by the integrated application for video communication with a physiotherapist. Safety and feasibility were assessed from patients, physiotherapists, and a technician using logbooks, interviews, and a questionnaire. Qualitative content analysis and descriptive statistics were used in the analysis. Results: Fourteen out of 15 patients finalized the training period with a mean of 19.5 minutes spent on training at each session. The DISKO-tool was found to be useful and safe by patients and physiotherapists. Conclusions: This study demonstrates the feasibility and safety of the DISKO-tool and provides guidance in further development and testing of interactive distance technology for home rehabilitation, to be used by health care professionals and patients in different phases of rehabilitation after stroke. © 2017 Taylor & Francis.

    Capturing TV user behaviour in fictional character descriptions2008Rapport (Övrigt vetenskapligt)
    Abstract [en]

    This work is part of the On-demand IPTV project, conducted by Acreo and SICS with financing from Vinnova and active support from an industrial consortium. The main goal of the project is to study the demands on cost-effective, scalable video-on-demand networks that can deliver video with high-quality with minor quality degradations in the transmission. An important issue in understanding this situation is to explore future user behaviour (and the resulting traffic patterns) when user can choose a mix of broadcast TV and a large number of on-demand channels and services. This paper reports on the first steps to develop an understanding of IPTV user behaviour by investigating the current situation using archetypical, fictional character descriptions often referred to as personas. This is an intermediate version; the final version will be the result of Task 4.1: User requirements analysis, part of WP 4: User needs and behaviour.

    How to choose and how to watch: an on-demand perspective on current TV practices2010Rapport (Övrigt vetenskapligt)
    Abstract [en]

    In Sweden, digital TV services have until very recently not been accessible to most people through the TV set. At the same time, TV channels offer more and more content on the web and the majority of the population has access to high-speed internet connections. A web survey aimed at investigating attitudes and behavior related to on-demand TV was distributed in December 2008 to 52 households in an experimental, open (operator neutral) access network in Sweden. Questions were posed on TV arrangements, habits and attitudes; social aspects of TV watching; watching film or TV on-demand; and watching film or TV using the computer. Complementary interviews were also performed with participants that were not part of the experimental environment. Results show that participants in the studies understood and felt a need for time-shift and on-demand TV services: time-shift needs for re-scheduling, catch-up and repeats were expressed as well as on-demand needs for movies and for accessing otherwise unavailable TV content. Support for on-demand TV could also be found in that subjects reported little need for viewing TV content according to a broadcast schedule, with the main exception of news, sports events and other live broadcasts.

    Age-related cognitive decline and navigation in electronic environments2006Doktorsavhandling, monografi (Övrigt vetenskapligt)
    Abstract [en]

    The older population is increasing, as is life expectancy. Technical devices are becoming more widespread and used for many everyday tasks. Knowledge about new technology is important to remain as an active and independent part of the society. However, if an old user group should have equal access to this technology, new demands will be placed on the design of interfaces and devices. With respect to old users it is and will be important to develop technical devices and interfaces that take the age-related decline in physical and cognitive abilities into account. The aim of this work was to investigate to what extent the age-related cognitive decline affects performance on different computer-related tasks and the use of different interfaces. With respect to the use of computer interfaces, two studies were conducted. In the first study, the information was presented with a hierarchical structure. In the second study the information was presented as a 3D-environment, and it was also investigated how an overview map could support navigation. The third study examined the age-related cognitive decline in the use of a small mobile phone display with a hierarchical information structure. The results from the studies showed that the most pronounced age-related difference was found in the use of the 3D-environment. Within this environment, prior experience was found to have the largest impact on performance. Regarding the hierarchical information structures, prior experience seemed to have a larger impact on performance of easy tasks, while age and cognitive abilities had a larger impact on performance of more complex tasks. With respect to navigation aids, the overview map in the 3D-environment did not reduce the age-differences; however, it contributed to a better perceived orientation and reduced the feeling of being lost.

    The effect of age-related cognitive differences, task complexity and prior Internet experience in the use of an online grocery shop2003Ingår i: Spatial Cognition and Computation, ISSN 1387-5868, E-ISSN 1573-9252, Vol. 3, nr 1, s. 61-84Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This study examined navigation and search in an on-line grocery store, and how solving those tasks was related to subjects' age, spatial ability, working memory, computer- and Internet experience. Task complexity was also included in the design of the experiment. In the study 48 subjects participated, there was one group of elderly and one group of younger subjects. The results showed that the elderly subjects needed more time to complete the tasks. Both age groups spent more time to find the items in the complex task, but there were also age differences for the complex task, where the elderly subjects spent more time with the complex task. It turned out that age, spatial visualisation ability and working memory had the strongest impact on performance for the complex task. For the easy task, on the other hand, Internet experience had the strongest impact on performance. Though this may seem discouraging to elderly users, it was also the case that the elderly, less experienced, subjects underestimated the time they spent performing the tasks. Thus, even if it took long time to solve the tasks, these elderly users did not experience it as such. Finally, implications for interface design of on-line grocery stores are discussed.

    Age differences and the acquisition of spatial knowledge in a three-dimensional environment: evaluating the use of an overview map as a navigation aid2005Ingår i: International Journal of Human Computer Studies, Vol. 63, s. 537-564Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This study examined age differences in the use of an electronic three-dimensional (3D) environment, and how the age differences were affected by the use of an overview map as a navigation aid. Task performance and the subjects’ acquisition of configural knowledge of the 3D-environment were assessed. Impact of spatial ability and prior experience on these measurements were also investigated. One group of older subjects (n=24) and one group of younger subjects (n=24) participated. An overall hypothesis for the work presented here was that differences in learning to and performing navigational tasks in the physical world are similar in learning and performing navigational tasks in the virtual world. The results showed that the older participants needed more time to solve the tasks; and similar to navigation in the physical world, the older participants were less likely to create configural knowledge. It could not be established that older participants benefited more from an overview map as cognitive support than younger subjects, except in the subjective sense: the older users felt more secure when the map was there. The map seemed to have supported the older users in creating a feeling of where objects were located within the environment, but it did not make them more efficient. The results have implications for design; in particular, it brings up the difficult issue of balancing design goals such as efficiency in terms of time and functionality, against maintaining a sense of direction and location in navigational situations.

    Perspectives on design of sensor based exergames targeted towards older adults2018Ingår i: Lect. Notes Comput. Sci., 2018, s. 395-414Konferensbidrag (Refereegranskat)
    Abstract [en]

    Serious games are an established field of study, where exergames provide a combination of conducting exercises and playing games. The aim of this work was to identify important features to include in, and design recommendations for exergames using sensor technology. The outcome of this work was two-folded. Firstly, a literature review of design guidelines with respect to older adults as users of exergames resulted in a categorized summary of design guidelines for specific target groups, e.g. people undergoing physical rehabilitation after stroke or injury or users suffering from a chronic disease. Secondly, these guidelines are discussed from various perspectives, based on insights from several years of work in the area. A general design guidelines covered by most of the literature is that exergames should provide a wide range of difficulty levels and be possible to adjust to individual needs. Insights from own work in the area highlight the importance of task and context relevant tools and devices. The result will serve as a starting point for a framework consisting of both general and domain specific design guidelines when designing sensor-based exergames for older adults.

    Using care professionals as proxies in the design process of welfare technology – Perspectives from municipality care2017Konferensbidrag (Refereegranskat)
    Abstract [en]

    Bringing real users into the design process is often seen as a successful way of creating useful IT systems. However, when it comes to designing for elderly, this is not always possible since many elderly suffer from age-related decline, both with respect to physical and cognitive abilities. This paper elaborates on the approach of working with proxies, in this case elderly care personnel. Different groups of people (N = 117) working with elderly and well familiar with needs and contexts around elderly were engaged in this study. Using a questionnaire and a more in-depth workshop we explored with municipality care professionals their experiences as well as the need to create a framework to improve such a proxy approach, and whether a method using care professionals as mediators could be possible to establish in elderly care. The results described in this paper are complementary to ours and others previous knowledge and show promising commitment and willingness to work in accordance with the proposed method.

    An Embodied question answering system for use in the treatment of eating disorders2008Ingår i: Proceedings of The 4th International Workshop on Human-Computer Conversation, 2008, 1, , s. 4Konferensbidrag (Refereegranskat)
    Abstract [en]

    This paper presents work in progress on implementing an embodied question answering system, Dr. Cecilia, in the form of a virtual caregiver, for use in the treatment of eating disorders. The rationale for the system is grounded in one of the few effective treatments for anorexia and bulimia nervosa. The questions and answers database is encoded using natural language, and is easily updatable by human caregivers without any technical expertise. Matching of users' questions with database entries is performed using a weighted and normalized n-gram similarity function. In this paper we give a comprehensive background to and an overview of the system, with a focus on aspects pertaining to natural language processing and user interaction. The system is currently only implemented for Swedish.
