A Context-Aware Locomotion Assistance Device for the Blind

Abstract : In this paper, we present a study which aims at designing a locomotion assistance device that can deliver semantic information about its surrounding environment at any time. As a first step towards this goal, we introduce an original model suited for the description of building structure, and we present an algorithm that exploits these descriptions. Then, we explain how it is possible to link semantics to structure. Finally, we expose some research directions for user positioning and human-computer interface design.
