Les Effets du Rythme sur l'Expérience Utilisateur lors de l'utilisation de Gestes Mid-Air en Réalité Virtuelle

In this work, we examine the effect of mid-air gesture rhythm on user experience in Virtual Reality. In particular, we investigate gesture regularity, speed and highlighting with a sound guide. We measure the effect of these components on the perceived fatigue, presence, difficulty, success and helpfulness. Our findings indicate that an irregular and slow rhythm leads to a lower arm fatigue. We also find that such an irregular rhythm could increase the user perceived difficulty of the task and the absence of a sound guide could decrease the sense of presence.
