    Towards Dependable Virtual Companions for Later Life2005Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    When we grow older, we become more vulnerable to certain reductions in quality of life. Caregivers can help, however human care is limited, and will become even scarcer in the near future. This thesis addresses the problem by contributing to the development of electronic assistive technology, which has the potential of effectively complementing human support. In particular, we follow the vision of a virtual companion for later life- an interactive computerbased entity capable of assisting its elderly user in multiple situations in everyday life.

    Older adults will only benefit from such technology if they can depend on it and it does not intrude into their lives against their will. Assuming a software engineering view on electronic assistive technology, this thesis thus formulates both dependability requirements and ethical guidelines for designing virtual companions and related technology (such as smart homes).

    By means of an iterative development process (the thesis covers the first iteration), a component-based design framework for defining dependable virtual companions is formed. Personalised applications can be generated efficiently by instantiating our generic architecture with a number of special-purpose interactive software agents. Scenario-based evaluation of a prototype confirmed the basic concepts of the framework, and led to refinements.

    The final part of the thesis concerns the actual framework components and the applications that can be generated from them. From a field study with elders and experts, we construct a functional design space of electronic assistive technology applications. It relates important needs of different older people to appropriate patterns of assistance. As an example application, the feasibility of driving support by vehicular communication is studied in depth.

    Future iterations with real-world experiments will refine our design framework further. If it is found to scale to the dynamic diversity of older adults, then work can begin on the ultimate project goal: a toolkit on the basis of the framework that will allow semi-automatic generation of personalised virtual companions with the involvement of users, caregivers, and experts.

    Abstract [en]

    Frail older people can normally not be given round-the-clock care-giving assistance. During the time there is no other person around they must be independent. Electronic assistive technology (EAT) can increase an older person's independence in everyday life, but to do so it must be dependable. This paper examines issues of dependability for a special class of EAT software, virtual companions for later life. A virtual companion is a personal system of interconnected functions aiming to assist an elderly user by imitating elder-caregiver interaction. In order to provide designers with an aid for defining, designing, and validating virtual companions, the first part of the paper identifies and discusses the special dependability requirements to be put on such software. The second part describes our own approach, and gives suggestions on how to design for dependability.

    Abstract [en]

    Resources in care for frail older people are limited. Electronic assistive technology can help maintain and improve older people's quality of life, however high requirements need to be put on such systems. As part of an iterative design process, this paper evaluates a framework for the design of interactive, multifunctional, and personalised assistive technology - virtual companions - in relation to previously defined dependability requirements. By means of scenario-based testing of a prototype implementation, we refine the first version of the design framework. The paper concludes with a reflection on our method, and outlines the iteration steps to follow.

    Abstract [en]

    More and more people are living to old age, and it is usually a desire among elderly people to sustain mobility. Unfortunately, the crash rate of older adults is much higher than for other drivers. Older drivers are also more likely to sustain serious injuries that lead to disability or death. Therefore, technological contributions for improving traffic safetyand preserving mobility of older people are important. One promising new approach is to use traffic safety systems based on vehicular communication, where vehicles exchange warning messages. This paper evaluates the feasibility of using such vehicular communication for supporting older drivers in road intersections, which is the most common accident setting for older drivers. Using a temporal reasoning system (ECAM) this accident setting is analysed in depth, and the potential foraccident avoidance is quantified, while taking into account several relevant factors such as speed, driver reaction time, and transmission delay for warning messages. The results indicate the high potential of vehicular communication, and highlight requirements on transmission delay.

    Abstract [en]

    An advanced look at smart technology to promote the independence of the elderly and disabled

    Ongoing research and advancements in technology are essential for the continuing independence of elderly and disabled persons. The Engineering Handbook of Smart Technology for Aging, Disability, and Independenceprovides a thorough analysis of these technologies and the needs of the elderly and disabled, including a breakdown of demographics, government spending, growth rate, and much more.

    Each chapter is written by an expert in his or her respective field, and gives readers unparalleled insight into the research and developments in a multitude of important areas, including:

    • User-need analyses, classifications, and policies
    • Assistive devices and systems for people with motor disabilities
    • Assistive devices and systems for people with visual and hearing impairments
    • Human-machine interaction and virtual reality
    • Assistive robotics
    • Technology for user mobility and object manipulation
    • Smart homes as assistant environments
    • A discussion of emerging standards and guidelines to build accessible devices, tools, and environments

    This book is an indispensable resource for researchers and professionals in computer science, rehabilitation science, and clinical engineering. It also serves as a valuable textbook for graduate students in the aforementioned fields.

    User modelling for live help systems2001Ingår i: Proceedings of the Second International Workshop on Electronic Commerce (Welcom'01) / [ed] G. Goos, J. Hartmanis, and J. van Leeuwen, Heidelberg: Springer Verlag , 2001, 1, s. 164-179Konferensbidrag (Refereegranskat)
    Abstract [en]

    We have explored the role of user modelling in live help systems for e-commerce web sites. There are several potential benefits with user modelling in this context: 1) Human assistants can use the personal information in the user models to provide the users with efficient support tailored to their personal needs; 2) Assistants can be more comfortable in their supporting role; 3) Consultation resources can be saved, and thus, financial savings can be made for the e-commerce company. A user modelling approachh as been implemented and deployed in a real web environment as part of a live help system. Following the deployment we have analysed consultation dialogue logs and answers to a questionnaire for participating assistants. This paper elaborates on these results, which show that assistants consider user modelling to be helpful and that consultation dialogues can be an important source for user model data collection. Based on lessons learned from the study, future directions for researchand development are carefully analysed and laid out.

    Originally we used the term web assistant system. However, similar system have recently begun to appear on e-commerce sites, commonly referred to as live help systems. To avoid future confusion we now refer to our work using this newly adopted terminology.
