Abstract
BACKGROUND: Visually impaired people have been considered only as “receivers” of support; however, few studies have considered them as “givers” of support to sighted people. OBJECTIVE: To support the walking of sighted people using information available specifically to the visually impaired. METHODS: Utilizing white cane usage data of visually impaired people to create inaccessibility maps for sighted people. RESULTS: A user study conducted with elderly people and their stakeholders, who had high accessibility needs found that the maps were generally useful as long as they were within the user’s area of interest. CONCLUSIONS: Although the proposed method should be practically beneficial to users, the information detected by the system should be expanded from white cane use data, its accuracy, and more data collected from visually impaired people.
