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)
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)
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)
The study of the potential of haptic channel to convey emotions is very promising for human-machine interaction and mediated communication. However, main researches investigated acted emotions that are not representative of natural and spontaneous behaviors. This paper addresses the issue of expression of spontaneous emotions. In the context of a game(More)
Does it feel the same when you touch an object in Augmented Reality (AR) or in Virtual Reality (VR)? In this paper we study and compare the haptic perception of stiffness of a virtual object in two situations: (1) a purely virtual environment versus (2) a real and augmented environment. We have designed an experimental setup based on a Microsoft HoloLens(More)
Several studies showed the relevance of haptics for conveying emotions to users. These studies usually cover recognition rate of emotions from haptic expressions. Surprisingly, the analysis of features of these haptic expressions is in counterpart often limited to a classical analysis of variance. However, this method suffers of several limitations for the(More)
