Abstract

The purpose of this paper is to investigate the viability and potential usefulness of a new method of modeling the open space around a blind person. As an alternative or complement to the usual approaches based on the detection of obstacles, we explore the usefulness of offering information on the temporal evolution of the center of area (CA) of safe navigation in relation to the blind person's position. This approach can be considered ergonomic, egocentric and polar, and easy to learn and use.
