CANBUS networked sensors use in orientation tools for the visually impaired wired versus wireless technology

An orientation tool called the Controlled Area Network BUS (CANBUS) assistive system was developed at the Dipartimento di Ingegneria Elettrica, Elettronica e dei Sistemi (DIEES) laboratories of the University of Catania. The CANBUS-based sensor network are used for the visually impaired wired and wireless technology. Both wired and wireless have allowed great improvement in the perception of environment. It provide dense sensing close to physical phenomena, process, and communicate this information, and coordinate actions with other nodes. This work has included the application of stochastic resonance theory to enhance tactile perception performance, the development of smart multi-sensor architectures in assisting the visually impaired in orientation and mobility tasks.
