ABSTRACT
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.
