Abstract
Loss of vision caused by infectious diseases has decreased significantly; however aging will increase the risk that more people acquire vision impairment. Visual information is the basis of most navigation tasks; a person is considered visually impaired when he has no appropriate information on the surrounding environment. With the latest evolution of digital technologies, the assistance provided to visually disabled people during their mobility can be improved. In this context, we propose a system to help the visually impaired move quickly and to know their environment. Indoors, the system uses a stereoscopic camera, a portable computer, and a headset to direct and help visually impaired persons navigate comfortably and securely in familiar and unfamiliar environments. Outdoors, a GPS is used as a positioning method to keep the visually impaired person on the right path; with its dynamic routing and rerouting capabilities, it provides the user with an optimized path. The system can work on an outdoor and indoor environment. A stereoscopic camera is used to detect visual indicators that are used to trace and validate user navigation, provide accurate indoor location measurements, and recognize objects in front of the user. This article is mainly focused on this system and detailed outlines description.
