Navigation with a sensory substitution device in congenitally blind individuals.
Vision allows for obstacle detection and avoidance. The compensatory mechanisms involved in maintaining these functions in blind people using their remaining intact senses are poorly understood. We investigated the ability of congenitally blind participants to detect and avoid obstacles using the tongue display unit, a sensory substitution device that uses the tongue as a portal to the brain. W...

By the use of GPS, outdoor travelling is easier with free maps e.g. Google Maps providing geographic information during navigation. For indoors, indoor spatial information is not much informed by Google Maps and neither do commercial products that a...
متن کاملCombinatorial Graph Creation and Navigation for Blind People
Blind individuals have been deprived of the use of diagrams as a form of knowledge representation and an aid to problem solving as well as a means of communication. Our focus is on providing them with access to a specific type of diagram – the node-link diagram, also known as a combinatorial graph. Graphs figure prominently in computer science and software engineering as well as chemistry and o...
