Indoor Route Following Tool for the Blind

This project develops an effective, indoor low-vision navigation aid, the KBT Indoor Route Following Tool, for individuals with low vision and age-related visual disorders. Individuals who are blind or have low vision can navigate outdoors using a cane, guide dog, or their own low vision as an aid; however, indoor navigation in large or unfamiliar buildings can be very challenging. The use of a GPS-based navigation device is effective outdoors but ineffective in large office buildings where the GPS receiver cannot receive the signal and there are no geographical databases devoted to the landscape of an office building. The KBT Indoor Route Following Tool addresses the problem of wayfinding in a building for the vision impaired.
