“…Most design teams working within assistive technology follow a user-led design methodology [2] and the Bath Institute of Medical Engineering (BIME) had long followed its own version of such methodologies [3], which has been very effective in previous design cases. The methodology is based on the recognition that most of the difficulties and unforeseen circumstances occur with the user-interface aspects of the design rather than the supporting technology.…”

This paper reports on the user requirements analysis, design and evaluation of smart home solutions for people with dementia. In order to be appropriate for people with dementia, smart home technologies should keep interaction with users to a minimum. In the work presented in this paper, discussions with carers, as well as a more formal user-survey, provided a good understanding of the issues that are faced by this group, and useful indications of potential design solutions. This preliminary survey work led to a design approach that used carer emulation, familiarity of appearance, incorporation of verbal prompts and reminders, and careful user-monitoring, to achieve effective devices. This design approach is illustrated through several examples of specific designs. Evaluations of stand-alone systems were carried out prior to smart home installation, and illustrated the complex interface that exists between assistive technology and people with dementia.

“…The latter requires detailed information about the nature of typing errors caused by motor disabilities. A number of specific typing errors related to disability have been noted in the literature [3,7,28,32]. In an earlier study, the author examined the effects of physical disabilities on typing accuracy for a group of 20 keyboard users [31].…”

One common typing error is the overlap error, in which two keys are pressed at once. The existing keyboard accessibility filters do not directly address overlap errors. Several techniques for automatic correction of overlap errors are compared in an offline analysis. Leveraging keystroke timing characteristics is shown to achieve a 50% to 75% reduction in errors for study participants with relatively high error rates. A simple heuristic for estimating the accuracy improvement for an individual using this filter is presented and considerations for live implementation and further work are discussed.

“…However, at the time of the study there was little work available on the application of design techniques for disabled users in practical situations. Whilst some authors present guides to the selection of particular methods [22,20] and some note the problems and issues specific to selecting methods of assessment for people with disabilities [7,19,20], little is discussed with regard to communication disabilities. The designer is therefore faced with a problem: how to uncover and thoroughly understand the perspectives of people with disabilities, along with their needs, wants and aspirations for disability devices.…”

Designing desirability in an augmentative and alternative communication device

This paper discusses work carried in the context of a study addressing the design and development of a wearable communication aid for people who are illiterate and cannot speak. People with such disabilities often depend on electronic augmentative and alternative communication devices for interpersonal communication. A central theme of the paper, however, is that such products, and products intended for people with disabilities more generally, have characteristics that inadequately attend to users' needs-in particular many devices pay insufficient regard to the psychological and sociological impact the devices have upon their users. The paper briefly discusses an empirical case study targeted to design and develop the Portland Communication Aid (PCA). The process of establishing user requirements, and in particular the notion of designerfacilitated participatory design, is discussed. The resulting prototype of the PCA is briefly explained along with a discussion of the importance of product semantics in the design of assistive technology.
