Abstract : This paper introduces the technical foundations of a system designed to embed a lightweight, faithful and spatially manipulable representation of the user's hand into an otherwise virtual world (aka Augmented Virtuality, AV). A highly intuitive control during pointing-like near space interaction can be provided to the user as well as a very flexible means to experimenters in a variety of non-medical and medical contexts. Our approach essentially relies on stereoscopic video seethrough Augmented Reality (AR) technology and a generic, extendible framework for managing 3D visual hand displacements. Research from human-computer interaction, perception and motor control has contributed to the elaboration of our proposal which combines a) acting in co-location, b) avoiding occlusion violations by assuring a correct scene depth ordering and c) providing a convincing visual feedback of the user's hand. We further present two cases in which this system has already successfully been used and then line out some other applications that we think are promising, for instance, in the fields of neuromotor rehabilitation and experimental neuroscience.
