Gestures Interactions for Immersive Communications

Video meeting and presentation systems are more and more widely used. Yet interacting or controlling such video systems is far from easy. Immersive communication aims to enable better interactions between end users and video systems. In this paper we propose an end-to-end study on gesture interactions for a video presentation system starting from the algorithms (i.e. algorithms enabling posture recognition) to the user evaluation (i.e. evaluation by users of gestural interactions). Index Terms-- Immersive Communication, Gesture, Posture, Recognition, Interactions, User Evaluation. 1. INTRODUCTION One of the key challenges of telecommunication industry is to identify the future of communication. Video is identified for long as the future of telecommunication, however use only pure video and audio will not deeply change the current mode of telecommunication. Therefore, we are defining immersive communication as the way to exploit video and multimedia technologies in order to create new relevant and valuable usages. Regarding the immersive communication aspect, our first focus of interest is the enterprise context where immersion can provide a better experience for meeting at distance, presentation at distance. Our approach can solve current issues of existing solutions such as the travel cost for face to face meeting or the cost for current tele-presence solutions [1]. The "Presentation at Distance" use case was chosen for its capability to illustrate numerous facets of the immersive communication model we are building.
