As one of the most important non-verbal communication channel, touch plays an essential role in interpersonal affective communication. Although some researchers have started exploring the possibility of using wearable devices for conveying emotional information, most of the existing devices still lack the capability to support affective and dynamic touch in interaction. In this paper, we explore the effect of dynamic visual cues on the emotional perception of vibrotactile signals. For this purpose, we developed Visu-alTouch, a haptic sleeve consisting of a haptic layer and a visual layer. We hypothesized that visual cues would enhance the interpretation of tactile cues when both types of cues are congruent. We first carried out an experiment and selected 4 stimuli producing substantially different responses. Based on that, a second experiment was conducted with 12 participants rating the valence and arousal of 36 stimuli using SAM scales.

Cet article présente une synthèse des résultats de deux études expérimentales menées dans le cadre d'un projet de recherche portant sur la conception et l'évaluation d'un système d'authentification graphique (HSA ® pour Human Semantic Authentication). Les deux expérimentations ont porté sur plusieurs dimensions de l'utilisabilité du système (la performance) et ses exigences au plan cognitif (mémorisation et catégorisation). Les résultats mettent en évidence que si ce type de système présente un intérêt potentiel en termes d'usage lorsque certaines conditions sont remplies, il soulève un ensemble de difficultés d'ordre perceptif et cognitif qui obère son utilisation et nous interroge sur la généralisation de son usage en situation réelle. Le système ayant été principalement imaginé pour renforcer la sécurité, ces résultats illustrent par ailleurs les tensions qui existent entre sécurité et utilisabilité.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
