Postural interaction is of major importance during job interviews. While several prototypes enable users to rehearse for public speaking tasks and job interviews, few of these prototypes support subtle bodily interactions between the user and a virtual agent playing the role of an interviewer. The design of our system is informed by a multimodal co...

The purpose of the present study was to evaluate the impact of four mood conditions (control, positive, negative, aroused) on movement expressivity during a fitness task. Motion capture data from twenty individuals were recorded as they performed a predefined motion sequence. Moods were elicited using task-specific scenarii to keep a valid context....

The present study aimed to examine multidimensional factors that contribute to a poor performance in a public speaking task. An adapted version of the Trier Social Stress Test (TSST) as used to elicit psychosocial stress among 43 university students and multidimensional assessments were involved to investigate acute stress responses by psychologica...

The creation of interactive installations is a process which implies to bring back together phenomenological evaluations of visitors' experiences and motion analyses which inherently highlight the core material of interaction design. In this paper, we present an interactive and immersive work, See me through you, which ambition to provide a rich ex...

Independent and interdependent self-construals are included in individuals’ self-definitions. The 24-item Self-Construal Scale (SCS) was developed by Singelis (1994) as a means of measuring the “two selves” of individual identity, namely the independent self and the interdependent self. It has been translated into a number of different languages in...

L'imagerie médicale révèle l'intérieur du corps humain sans physiquement ouvrir ce dernier. Devenue nécessaire dans l'établissement d'un grand nombre de diagnostics cliniques, l'imagerie médicale donne à voir de différentes façons l'anatomie et la fonction des organes internes. La présence de plus en plus prégnante dans notre quotidien de ces image...

Virtual sport coaches guide users through their physical activity and provide motivational support. Users’ motivation can rapidly decay if the movements of the virtual coach are too stereotyped. Kinematics patterns generated while performing a predefined fitness movement can elicit and help to prolong users’ interaction and interest in training. Hu...

Objectifs de l’étude Analyser les liens entre traits de personnalité et caractéristiques de la latence de la synchronie Tâche de coordination de mouvements fitness entre un coach et son élève Mesure de trois traits à composantes interpersonnelles du Big Five : l’extraversion, l’agréabilité et le névrosisme

Entretien d’embauche: Analyse et modélisation de l’interaction corporelle

With the rapid developments of medical imaging, our personal inner body can be unveiled as never before. Medical images are usually considered as ordinary objects and their potential intimate value is never really considered. In this paper, we present an exploratory installation which anticipates prospective issues when medical and self-images inte...

A dichotomy exists in the way virtual embodiments are currently studied: embodied entities are considered by conversational approaches as other selves whereas avatar approaches study them as users' hosts. Virtual reality applications such as in our case study often propose a different, in between embodiment experience. In the context of a virtual h...

Databases of spontaneous multimodal expressions of affective states occurring during a task are few. This paper presents a protocol for eliciting stress in a public speaking task. Behaviors of 19 participants were recorded via a multimodal setup including speech, video of the facial expressions and body movements, balance via a force plate, and phy...

Postural control is a dynamical process that has been extensively studied in motor control research. Recent experimental work shows a direct impact of affects on human balance. However, few studies on the automatic recognition of affects in full body expressions consider balance variables such as center of gravity displacements. Force plates enable...
