Results & Discussion. – Small robots with some traits between human/animal and machine were appreciated by the participants. As regards
services, cognitive stimulation, reminder and object localization were positively rated. Although the participants considered an assistive robot as
useful, they were not yet ready to adopt it. The expressions of the robot were perceived differently in older and young adults. Thus, a robotic system
dedicated to older adults should be tailored to the specific characteristics of this population. We also identified social signals as indicators of the
user’s engagement level during interaction. Finally, the issue of the added valued of a robotic system in comparison to a laptop was raised by our
participants. Therefore, various issues (technological development, human-robot interaction, social context. . .) are to be explored before testing
the impact of the robot at home.
