Dynamic electronic map of 3D space representation: an approach to obstacle avoidance of visually impaired

The intelligent glasses system (IGS) ongoing research project at Robotics Laboratory of Paris (LRP), University Paris 6, and Atomic Energy Commission (CEA), is an electronic travel aid (ETA) which provides useful information on the 3D environment structure. The IGS assists users in obstacle avoidance by providing them their nearest environment tactile map where obstacles positions are represented. This work makes an overview of the IGS project and outlines a set of experiments for visuo-tactile man-machine interface validation (HuPer project ; CNRS, Robea program).
