Abstract : With the increase of life expectancy, aging in place is today a major concern for developed and emerging countries. Among the key solutions to explore, gerontechnologies are seen as the most promising. However, their evidence-based efficacy remains to be demonstrated for independent living or even for their usability and acceptance by the targeted old users. In this context, a user-centered conception methodology has been implemented for designing a multi-task and multi-domain (supporting everyday activities, safety, and social participation) assisted living platform targeting frail older adults with functional decline. This platform is named HomeAssist. Based on an analysis of physical, cognitive and fonctional abilities (study 1) and assistive technology needs (study 2) of our sample, HomeAssist has been designed with the originality of providing multi-domain services. Indeed, HomeAssist proposes an activity monitoring system to provide context-aware assistance (study 3), and a unified human-computer interaction system (study 4); while promoting self-determination (study 5). Results underpined the reliability of our activity monitoring system, and reinforced the rationale of our design principles, concerning the unified interaction system and the self-determination support. Notably, positive outcomes in terms of usability and acceptance of the system, as well as benefits concerning users’ feeling of self-determination have been obtained. From this, a last study (study 6) evaluated the benefits from a six-month use of HomeAssist, on functional abilities of frail older adults and caregiver burden. A positive effect of HomeAssist on functional status was obtained (“protective” effect reported by the professional caregivers), as well as a reduction of objective dimension of caregiver burden. Taken together, the results from these pilot studies are encouraging and open numerous research perspectives with high societal impact concerning the promotion of aging in place.
