Conditions of use of a social-link technology by elderly people: psycho-ergonomics issues for home care

Abstract

The objective of this study is to assess the conditions of use of a device for social-link for home care of dependent elderly people. From the assessment of the performance of use (usability) and the intentions of use (acceptability) on two groups of 15 users (seniors and very old people), we show on the one hand, that this environment is not adapted to the characteristics and abilities of older persons and, on the other hand, that does not meet the expectations of these individuals. The difficulties of use destabilize and undermine these people. From these observations, we propose a series of ergonomic recommendations and for accompanying training.
