Eliciting user requirements with older adults: Lessons from the design of an interactive domestic alarm system

This paper documents how methodological challenges were addressed when identifying user requirements for an Interactive Domestic Alarm System (IDAS) designed to enable older adults to live independently in their own homes for longer. A novel approach to determine possible IDAS functionality is described, and the results of focus groups conducted with older adults and care workers are reported. The paper identifies some difficulties encountered when using the focus group method with an ageing sample, and highlights the importance of careful preparatory work if this method is to be used successfully in such a context

Simulating naturalistic instruction: the case for a voice mediated interface for assistive technology for cognition

A variety of brain pathologies can result in difficulties performing complex behavioural sequences. Assistive technology for cognition (ATC) attempts support of complex sequences with the aim of reducing disability. Traditional ATCs are cognitively demanding to use and thus have had poor uptake. A more intuitive interface may allow ATCs to reach their potential. Insights from psychological science may be useful to technologists in this area. We propose that an auditory-verbal interface is more intuitive than a visual interface and reduces cognitive demands on users. Two experiments demonstrate a novel ATC, the General User Interface for Disorders of Execution (GUIDE). GUIDE is novel because it simulates normal conversational prompting to support task performance. GUIDE provides verbal prompts and questions and voice recognition allows the user to interact with the GUIDE. Research with non-cognitively impaired participants and a single participant experiment involving a person with vascular dementia provide support for using interactive auditory-verbal interfaces. Suggestions for the future development of auditory-verbal interfaces are discussed

Experimenting with the use of persona in a focus group discussion with older adults in Malaysia

Eliciting user-requirements from older adults -- especially amongst non-users -- can be challenging. This is due to the fact that older adults are varied in term of their functional abilities and experience with technology. The common User-centered design (UCD) techniques such as focus group and interviews were found to be less effective with older adults. Inspired by the benefits of persona in enhancing designer's attention through narrative and storytelling, the study reported in this paper tested persona as a communication tool in a focus group discussion with older adults in Malaysia. The study was carried out to gather Malaysian older adults' needs and requirements for the development of a prototype email application. Findings and feedbacks from the study shows that persona can be a potential technique to be applied in working with older adults. The use of persona in a focus group discussion does not only benefit the researchers and designers but also the participants -- particularly in building interest among non-users to embrace computers

Three case studies on methods of working with older people in the design of new technologies

The proportion of older adults in the population is rapidly increasing and the proportion of younger adults to care for them is decreasing. Part of the solution to support older adults in living independently is to provide them with appropriate assistive technologies. To develop technologies that are effective for older adults we need methodologies that are appropriate for working with this user group. Yet there is little systematic research on how to work with older adults and how to adapt methods already used with younger adults. This paper reports on three case studies which investigated the use focus groups, expert evaluations and user evaluations with older adults. In the case of focus groups, the size of the focus group was investigated; for expert evaluations, an existing set of heuristics for evaluating apps for older adults was investigated; for user evaluations, a low-fidelity prototype design was evaluated using think-aloud protocol

Citizen Participation and engagement in the Design of e-Government Services: The Missing Link in Effective ICT Design and Delivery

Enid Mumford championed an ethical, socio-technical, and participatory approach to the design of ICT systems. In this paper, we focus on the development of e-government as an example of such a system. First, we present an extension of Mumford¡¯s ideas about the benefits and process of participation, based on an analysis of recent citizen engagement initiatives. We then examine the extent to which e-government reflects the principles she espoused. The evidence collated indicates that e-government development is currently characterised by a technocentric approach with minimal engagement of citizens. We discuss the implications arising from this analysis, and explore the benefits that governments could achieve from adoption of a socio-technical, participatory approach to e-government development. The crucial enabling role of capacity building is highlighted. Providing citizens with the necessary skills and capabilities to engage effectively offers the key to the successful development of systems such as e-government which impact our lives in the 21st century Information Society

Cognitive function and assistive technology for cognition: A review

The relationship between assistive technology for cognition (ATC) and cognitive function was examined using a systematic review. A literature search identified 89 publications reporting 91 studies of an ATC intervention in a clinical population. The WHO International Classification of Functioning, Disability and Health (ICF) was used to categorize the cognitive domains being assisted and the tasks being performed. Results show that ATC have been used to effectively support cognitive functions relating to attention, calculation, emotion, experience of self, higher level cognitive functions (planning and time management) and memory. The review makes three contributions: (1) It reviews existing ATC in terms of cognitive function, thus providing a framework for ATC prescription on the basis of a profile of cognitive deficits, (2) it introduces a new classification of ATC based on cognitive function, and (3) it identifies areas for future ATC research and development.
