Haptic expression of emotions has received less attention than other modalities. Bonnet et al. [2011] combine visio-haptic modalities to improve the recognition and discrimination of some emotions. However, few works investigated how these modalities complement each other. For instance, Bickmore et al. [2010] highlight some non-significant tendencies of(More)
This paper deals with the haptic affective social interaction during a greeting handshaking between a human and a humanoid robot. The goal of this work is to study how the haptic interaction conveys emotions, and more precisely, how it in'uences the perception of the dimensions of emotions expressed through the facial expressions of the robot. Moreover, we(More)
Several studies have investigated the relevance of haptics to physically convey various types of emotion. However, they use basic analysis approaches to identify the relevant features for an effective communication of emotion. This article presents an advanced analysis approach, based on the clustering technique, that enables the extraction of the general(More)
Exploring virtual environment with immersive metaphor is still largely unexplored, with the costly CAVE exception. This question takes importance in lots of fields, such as fluid mechanics, where space and time resolved dataset become more and more common. For that reason, we present an interaction design study of an window exploration metaphor, for large(More)
Eliciting emotions to collect affective expressions is frequently used in studies about facial, spoken or bodily expressions of emotions. However, recent works in affective hap tics focus mostly on expressions of acted emotions. The expression of spontaneous emotions using the haptic modality remains unexplored. This paper discusses methodological(More)
The use of virtual avatars, through facial or gestural expressions, is considered to be a main support for affective communication. Currently, different works have studied the potential of a kinesthetic channel for conveying such information. However, they still have not investigated the complementarity between visual and kinesthetic feedback to effectively(More)
