International audienceIn this paper, we present a multi-modal perception based framework to realize a non-intrusive domestic assistive robotic system. It is non-intrusive in that it only starts interaction with a user when it detects the user's intention to do so. All the robot's actions are based on multi-modal perceptions which include user detection based on RGB-D data, user's intention-for-interaction detection with RGB-D and audio data, and communication via user distance mediated speech recognition. The utilization of multi-modal cues in different parts of the robotic activity paves the way to successful robotic runs (94% success rate). Each presented perceptual component is systematically evaluated using appropriate dataset and evaluation metrics. Finally the complete system is fully integrated on the PR2 robotic platform and validated through system sanity check runs and user studies with the help of 17 volunteer elderly participants
Lors de la réalisation d'exercices de rééducation cognitive informatisée pour des patients présentant une maladie d'Alzheimer, nous avons noté une difficulté à reconnaître certains objets. Si nous envisageons de les étiqueter pour favoriser leur reconnaissance, quelles caractéristiques typographiques, au sens large, la police de caractère doitelle avoir pour être lisible ? En éclairant les résultats de la revue de la littérature par notre pratique, il nous semble que la meilleure ergonomie visuelle est obtenue avec la police de caractères Verdana de taille 14 au minimum. Pour citer cette revue : Cah. Année Gérontol. 2 (2010). Mots clés Lisibilité · Troubles cognitifs · Personnes âgées · Police de caractère · Écran d'ordinateurAbstract When using computer-based cognitive rehabilitation, we observed that Alzheimer's disease patients tended to fail in recognizing some objects. If we consider labelling them to help with recognition, then what would be the required typographic features (in the wider acceptation). By a study of the literature along with practical experiments, we found that the Verdana font at a minimum size of 14 points seems to offer the best visual ergonomics.Tocitethisjournal:Cah.
