Power seat functions (PSFs) allow power wheelchair users to adjust their posture independently for preventing pressure ulcers, ameliorating other medical conditions, and to assist with daily activities. Use of PSFs requires analysis of current environment, body position, and clinical recommendations, but these can be complex tasks for some users. We are developing an electronic coach system, entitled "Virtual Seating Coach" (VSC), to prompt users to use PSFs appropriately and warn against adverse events from improper use of PSFs. We conducted a survey to understand users' preference for PSF feedback modalities; PSF users and clinicians were recruited. They reviewed modalities with various features using a computer demonstration program, answered a questionnaire, and participated in a face-to-face interview. Trends in preferences for indicator and feedback modalities were identified, but some diversity of opinion also appeared. Findings from this survey study will guide the selection of VSC feedback modalities to accommodate individual differences.
