The spatial abilities of the visually impaired are discussed. Former approaches of outdoor navigation systems for the blind are analysed and deemed inappropriate for the purpose of modelling indoor navigation. The proposed routing algorithm for the blind calculates routes based on physical characteristics of travelling with a long cane. The algorithm distinguishes between clues, landmarks, obstacles, and hazards along the feasible paths and selects the optimal route by trading off distance and the number of landmarks and clues along a route. Subsequently, the routes for the blind are compared to routes calculated by the routing algorithm for the sighted. The paper asserts that the proposed indoor routing algorithm leads to more suitable routes for the blind.
