Are guidelines enough?: an introduction to designing web sites accessible to older people

As the Web becomes more integral to day-to-day life, there is a danger that many older people will be excluded if their access needs are not considered by content designers. Although accessibility guidelines for designers are available, experience shows that these guidelines have not been successful enough in producing Web sites accessible to older people. In this paper, the shortcomings of relying solely on accessibility guidelines are reviewed, and several ideas are proposed for encouraging a more holistic approach to accessibility.

Methodologies for involving older adults in the design process

Older people provide much greater challenges to user-centred design than more traditional user groups. It is also very important to encourage (often young) designers to develop a relationship with, and an empathy for, older users. It is recommended that older users be fully integrated into the design process. Researchers, however, need to take care to be sensitive to the characteristics, sensory and cognitive capabilities, and the attitudes of older people to computers and to being included in research studies. The paper suggests strategies for doing this, together with the more radical approach of using professional actors as surrogates for real older users.

Theatre as an intermediary between users and CHI designers

We have investigated the possibilities of using theatre, including professional actors, scriptwriters and artistic directors, within requirements gathering, and usability testing, and for communicating the results of such work to the design community, or individual designers. The research on which we will report focuses on older people, but we believe that a consideration of the issues involved in designing for this group highlights many of the challenges found in CHI research more generally, and the techniques can apply to usability testing, and to communicating the findings of such research and testing to designers.

Digital switchover or digital divide: a prognosis for usable and accessible interactive digital television in the UK

The move toward digital switchover increases content and introduces interactive services available through the television. UK legislation advocates universal access and equitable provision of services, across all platforms and equipment, particularly for ‘vulnerable’ groups. However, key aspects of usability and accessibility have been overlooked by those responsible for encouraging this new infrastructure’s inclusive development. Aspects of previous interactive television provision and developments in web accessibility appear to have been ignored, along with findings from relevant user-centred research and even from specifically commissioned reports. This paper will identify these issues and discuss their impact on the inclusiveness of DTV.

Factors facilitating or impeding older adults' creative contributions in the collaborative design of a novel DTV-based application

This article describes some of the challenges of supporting older adults’ creative input to the design of an (as yet) undefined digital television application. Focusing on commonly used brainstorming and paper prototyping techniques, constructive insights are gathered from users with limited experience of interactive technology. Encouraging older participants to move beyond what they are familiar with, the research reports on how fragmented conceptual knowledge of familiar technologies can either facilitate or impede the creative development of new ideas. This includes bias or contradictory ideas that can emerge in the elicitation process. As reported, other factors, such as the self-perception of inadequate drawing skills, demonstrate further barriers for some older adults to articulate their visions and aspirations for suitably designed technology.

Modeling the Socially Intelligent Communication of Health Information to a Patient's Personal Social Network

This study examined how emotional proximity and gender affect peoples information requirements when someone that they know is chronically or critically ill. In an online study, participants were asked what information they would want to receive about members of their social network in three categories: someone who was very close, someone who was not so close, and someone who was not close at all. Our results show that the information that people want can be predicted from their gender and emotional proximity to the network member. The closer the relationship with the patient, the more information people want. Women want more information than men. We propose a model for the socially intelligent communication of health information across the social network, and discuss areas for its application.

An Exploratory Study Examining the Appropriateness and Potential Benefit of the Nintendo Wii as a Physical Activity Tool in Adults Aged ≥ 55 Years

This study investigates the physical exertion of playing the Nintendo Wii (R) (Wii) and determines the appropriateness and potential benefit of it as a physical activity tool for older adults. Twenty healthy adults (aged 61 +/- 6 years) took part in a single session using a selection of the Wii Sports and Wii Fit games. During the gameplay session, heart rate and perceived exertion were measured. Pre- and post-session, we investigated mood using the Positive and Negative Affect Schedule (PANAS) and cognitive function (i.e. aptitude, abstract reasoning and problem solving) using the test of non-verbal intelligence (TONI-IQ) and trail B tests. We also gathered subjective feedback from participants using semi-structured interviews and questionnaires. Three of the game activities (hula-hoop, rowing squat and leg extension) were identified to reach a moderate level of heart rate intensity, with one activity (jogging) corresponding to a vigorous level. We identified that post-session PANAS-positive subscale scores were greater than pre-session scores (P < 0.01). There was a reduction in the time to complete the TONI-IQ test from pre- to post-session (P < 0.05). Findings from these data identify that some Wii activities were of an intensity required for health benefits; a single Wii activity session can result in positive mood changes and the Wii interface is generally acceptable and appropriate for this older age adult group. Further randomized controlled and longer term intervention trials are needed to determine the effectiveness of exergame activity programmes.

iTV as a Platform for Rich Multimedia Reminders for People with Dementia

This paper gives an overview of a reminder system, based on digital television technology, which can present rich multi-media prompting messages in order to help maintain a regular daily schedule for people with mild to moderate dementia. The ongoing development of this application has the aim of supporting busy carers by making it easy to create, adapt and maintain a schedule of reminders to help keep a regular daily routine, relieving some of the burden of care and freeing more time for better human contact and interaction.

Designing computer systems for and with older users

The ageing population in the developed world, and the centrality of computer systems in many aspects of daily life, are factors commonly cited as necessitating the provision of computer technologies appropriate for older users. Much of the research on older people and computer systems is undertaken and presented with a crusading zeal, based on the assumption that computer systems are, of themselves, a positive influence on the lives of older people (Selwyn et al. 2003). We have argued elsewhere that insufficient data exist to determine whether or not computer systems, as they are currently constituted, improve wellbeing among older users (Dickinson and Gregor 2006). In this special issue, we have focused on approaches, techniques and methodologies that support a fuller and more sophisticated analysis of the relationship – or potential relationship – between older adults and computer systems. The seven selected papers published here offer a variety of perspectives on this area, and add both empirical data and theoretical richness to the field. The paper by Convertino and colleagues explores theoretical issues of intergenerational collaborations using computer supported collaborative work (CSCW) in a work environment. The authors persuasively argue the vital point that older workers bring different – not fewer – talents and qualities to intergenerational work relationships. Comparative lack of technical knowledge is offset by valuable and extensive domain expertise and problem-solving skills. To maximize usefulness to industry, where such skills are highly valued, designers of such systems should aim to support these talents and qualities as well as those of younger workers. Another paper which benefits from a strongly theoretical approach is the work by Turner et al. who use ‘learned helplessness’ theory to explore the qualitative and discursive outcomes of a nine month study of older adults learning to use interactive systems. Their analysis of the experiences of the learners, and the ways in which these are described in conversation, provides us with important and rich information on the barriers that older adults perceive to their own computer use. An important theory which informs the paper by Sokoler and Svensson is that of non-stigmatizing technologies and the ways in which these might be developed. The work, based on qualitative field work in residential homes, focuses on the difficulties of inducing people explicitly to recognize and express feelings that might be regarded as stigmatizing, such as loneliness and isolation. Arguing that older adults themselves have various strategies for dealing with such problems in indirect, non-stigmatizing ways, the authors seek to develop technology that enables such strategies, rather than technology that stigmatizes the recipient through defining them as having a problem such as, for example, being ‘lonely’. These theoretical approaches and, in the case of Sokoler and Svensson, the production of a prototype system, are thought-provoking and useful, offering new insights into the issues surrounding older adults’ use – or non-use – of computer systems. Renaud and Ramsay report on the development of an identification and authentication procedure to increase the accessibility of web content to older users, through focusing on strengths which do not change with age, such as recognition of one’s own handwriting, rather than current approaches that demand perfect recall. The system developed provides a number of insights into ways in which designs can be made more widely accessible and in which the seriousness of user errors can be reduced without compromising security. The special issue concludes with three papers focused on methodological strategies for working with older adults. Rice et al. look at the use of requirements gathering techniques adapted from Forum Theatre in working with older adults. These techniques, the authors argue, allow the social and attitudinal implications of potential technologies to be explored with people who may have little technical knowledge, thus overcoming significant communication barriers between older users and designers. They report on sessions carried out with older participants on the topic of interactive television to illustrate the richness of the data gathered with these techniques. In his paper, Hawthorn explores adaptations to user centred design techniques using the example of the development and evaluation of a tutorial program, FileTutor, which teaches older people about file management.
