A comprehensive usability study was conducted to assess the suitability for older adults of the ‘Remote Gateway’ (RG), a prototype portable wireless automated integrated environmental control device. Using a full-scale simulated living room and bedroom, 153 older adults, half of whom had mobility restrictions, participated in a protocol where they were introduced to, observed and experimented with the RG. A subset of the sample (n=79) also performed eight daily living tasks (e.g. answering the telephone, turning lights and TV on/off, and answering a door) both manually (without the RG) and electronically with the RG. Data collected included behavior observations of task times, task-associated problematic behaviors, as well as questionnaire data on several dimensions related to the RG, e.g. aesthetics, cost, advantages and disadvantages, and personal interest in adopting the RG. Results showed, overall, the RG performed well. The seniors executed the daily living tasks with relatively few associated problems, which was reflected in positive self-reports of the overall usability of the device. The mobility restricted seniors felt the RG was more difficult to use and more difficult to hold than the less disabled seniors. The older adults stated a clear preference for the RG to be connected to household items that enhance personal safety, e.g. surveillance cameras. Although the participants clearly perceived the RG to be of benefit to seniors with mobility disabilities, relatively fewer perceived the RG in terms of convenience or as a device that could potentially prevent in-home accidents. Specific design recommendations for the RG are also offered.
