— Serious Game is considered currently as a new non-medicated measure to the advantage of seniors, allowing to maintain good health in the playful conditions by doing cognitive and physical exercises. However, user's motivation is still a problem that needs to be studied more precisely. Indeed, most of them previously have neither game culture nor knowledge of new technologies (camera, computer). We propose in this paper a system which is able to initiate older people into Serious Games. Consisted of a recognition module and of a communicative interface with an animated avatar, the système accompanies the player in his game experience. 19 participants are recruited during their memory consultation and are tested the functioning of this system. Only 3, having an impaired mobility for the one and the disorders of understanding for 2 others, did not manage to interact with the system. We propose an improvement to bring more advice when the player faces difficulties in the course of the game session.
