Haptic Expression and Perception of Spontaneous Stress
Résumé
Previous studies about kinesthetic expressions of emotions are mainly based on acted expressions of emotions, which can be quite different from spontaneous expressions. This paper describes a study involving a stress induction procedure and stress perception through haptic expressions with Ntotal=41 young men (aged 19−37), all right-handed. We designed a game application to collect spontaneous expressions of stress. This application involved haptic interactions and a stressful event. We observed changes in the haptic behaviors of the participants over different phases: before, during and after the stress induction. In the next step, we investigated how the collected haptic behaviors (both kinematic and force components) were haptically perceived by the other participants. The results suggest the ability of kinesthetic expressions to communicate a spontaneous stress from one person to another.
