Description
Summary:The aim of this study was to evaluate a range of alternative computer input devices suitable for people with disabilities and to provide comparative data that will enable health care professionals and users to make informed choices when selecting products. Our focus was on the potential advantages and disadvantages of individual product features as they related to the abilities and needs of different users. A sample of 14 alternative keyboards and pointing devices commonly used by people with disabilities were appraised by 35 disabled adults. A multi-disciplinary panel of independent assessors also appraised the products. We identified key factors regarding the set-up, personal acceptability, ease of use, design features, compatibility and potential limitations of each device. We found that difficulties in accessing computers could sometimes be reduced or overcome by adjusting the existing workstation and customizing computer settings rather than through additional technology. However, successful computer access often requires a combined approach, as a single piece of equipment will rarely provide a complete solution. If alternative computer input devices are necessary, it is likely that the hardware settings will need customizing.
