The University of Guelph has expanded its electronic wayfinding system for blind and visually impaired people. The system, called BlindSquare, helps people to navigate around campus using wall-mounted beacons that transmit signals picked up by a dedicated app. When the user moves indoors, the system uses battery-operated Bluetooth signals to help users navigate by telling them where corridors, elevators, stairways, and campus landmarks are. Over 400 GPS-enabled service points have been installed on the main campus, the U of G Arboretum, and the downtown Guelph campus. The system allows students to access multiple layers of information about their location and can be continually updated so that it stays current.
