Abstract
The U.S. Department of Transportation's Inclusive Design Challenge spurred innovative research promoting accessible technology for people with disabilities in the future of autonomous transportation. This paper presents the user-driven design of the Autonomous Vehicle Assistant (AVA), a winning project of the challenge focused on solutions for people who are blind and visually impaired. Results from an initial survey (n = 90) and series of user interviews (n = 12) informed AVA's novel feature set, which was evaluated through a formal navigation study (n = 10) and participatory design evaluations (n = 6). Aggregate findings suggest that AVA's sensor fusion approach combining computer vision, last-meter assistance, and multisensory alerts provide critical solutions for users poised to benefit most from this emerging transportation technology.
