The Intelligent Glasses System (IGS) is an Electronic Travel Aid (ETA) that gives users a simplified representation of the 3D environment. It takes into account the obstacle avoidance task constraints and assists users in obstacle avoidance by providing them a nearest environment tactile map where the obstacles are represented .The originality of this system compared to existing devices is mainly due to an easily interpretable and user adapted representation of 3D space orthogonally projected on a 2D touch stimulating surface. This representation takes care of the most important part of user’s requirements: quick interpretation, global environment dynamic representation, wearable device.
The task of an ETA is to assist blind people in obstacle avoidance. The design of the IGS is motivated by presently available aids’ limitations, by technology progresses on system integration allowing new concept integration to the electronic system and by the progresses on the human perception physiology.
We present an analysis of an obstacle avoidance task and propose an integration of the analysis result into a real system, the Intelligent Glasses System. We propose experiments in order to validate the 3D world edge representation with vibro-tactile stimulation pad. The future works for research related to the Intelligent Glasses System have also been discussed here.
