HomeAssist: A Platform for Assistive Living
Participants : Charles Consel [correspondent] , Adrien Carteron, Julien Durand, Lucile Dupuy, Hélène Sauzéon.
The HomeAssist platform proposes a systemic approach to introducing an assistive technological platform for older people. To do so, we formed a trans-disciplinary team that allows (1) to identify the user needs from a gerontological and psychological viewpoint; (2) to propose assistive applications designed by human factors and HCI experts, in collaboration with caregivers and users; (3) to develop and test applications by software engineers; (4) to conduct a field study for assessing the benefits of the platform and assistive applications, in collaboration with caregivers, by deploying the system at the actual home of older adults.
The HomeAssist platform is implemented on top of the DiaSuiteBox platform, using a suite of tools, namely DiaSuite, that have been designed, developed and tested by our research group at Inria. The DiaSuite tools include a dedicated integrated development environment that enables applications to be developed quickly and safely. This technology has been successfully applied to a variety of domains where environments consist of networked objects that need to be orchestrated.
HomeAssist offers an online catalog of applications. Using this catalog, the user and the caregiver determine what and how activities should be assisted by selecting the appropriate assistive applications and configuring them with respect to the user’s requirements and preferences. The resulting set of applications forms a personalized assistive support. Additionally, to respond to evolving needs, our platform allows to stop/remove applications easily and to install new ones from the online catalog.
This platform proposes many applications in three domains of everyday life.

Several entities have been identified to deliver an assistive support. These entities include (1) technological devices: wireless sensors (motion detectors, contact sensors and smart electric switches), and two tablets, and (2) software services (agenda, address book, mail agent, and photo agent) to monitor everyday activities and propose assistive applications. Sensors are placed in relevant rooms in the house: kitchen, bedroom, bathroom, and around the entrance.
A field study is currently being conducted with elderly people. The major purpose of this study is to identify the benefits of using HomeAssist for this population in an ecological framework. We selected 24 elderly people with different levels of autonomy (GIR scores). The HomeAssist technology has been installed in their house during 9 months. Twenty-four non-equipped older adults were also selected to participate to the study, as control participants.
The expected impact of HomeAssist reflects the trans-disciplinary nature of the project. We aim to deliver results in the domain of (1) elderly care, (2) ergonomics and human factors, and (3) pervasive computing.
The major expected results are that HomeAssist (1) prolongs ageing in place, improves well-being of the users, and improves the efficiency of the caregiving environment; (2) is a cognitively low-cost assistive technology, and is well accepted and perceived as useful and usable by the users; (3) is technologically robust, and is a validated assistive platform.
The preliminary results of this field study show that the platform is well adopted (highly accessible and usable) by the older users and their families or caregivers.
Additionally, these results support our claim that DiaSuiteBox is effective in terms of:
Most notably, this pilot project also uses a systemic approach to assistive living as illustrated by (1) its funding sources involving key stakeholders of the caregiving domain, including a territorial agency of Gironde dedicated to ageing, as well as the regional branch of the national public retirement organization (i.e., CARSAT of Aquitaine), (2) their partners operating caregiving services (UDCCAS Gironde), and (3) The regional Chamber of Trades and Crafts to assist the older adults in installing and positioning the devices.
Final results are expected in March 2016.
The HomeAssist platform is being developed with support from the following partners:
