Utilization of Human Scale SPIDAR-G in the framework of Assistance to 3D interaction in a semi-immersive AR/VR platform

We have developed a generic assistance paradigm to 3D interaction that uses virtual guides to constrain the output of classical 3D interaction techniques, in order to satisfy the requirements of particular applications. In this article, we present this paradigm and its application to three different projects, dealing with robot teleoperation (constraints over precision and security), complex molecules manipulation (biological constraints over the plausible space configurations) and precise 3D navigation in underwater sites. Within these projects, we have used a human scale SPIDAR-GH in a semi-immersive AR/VR platform for assisted selection, manipulation and navigation tasks. Tracking and force feedback capabilities have been tested and some quantitative and qualitative results are presented.
