Abstract

This work falls within the broader framework of visual prostheses conception for blind people suffering from a retina photoreceptor cells degenerative disease. Studies on the issue of informational content of the prosthetic vision propose, in majority, a simple reduction in the resolution of greyscale images from a single camera. Our work proposes a novel approach based on functional vision. This functional vision is dedicated to specific needs in mobility, and is based on a simple analysis and less ambiguous representation of the scene layout. Emphasis is placed on the usefulness of providing access to 3D information combined with the use of an eye tracking device that should greatly improve spatial knowledge acquisition. This work presents extraction and proper formatting of data from optical sensors in order to establish a coherent vision based on the generation of a limited number of phosphenes.
