Abstract

We explore using vibration on a smartphone to provide turn-by-turn walking instructions to people with visual impairments. We present two novel feedback methods called Wand and ScreenEdge and compare them to a third method called Pattern. We built a prototype and conducted a user study where 8 participants walked along a pre-programmed route using the 3 vibration feedback methods and no audio output. Participants interpreted the feedback with an average error rate of just 4 percent. Most preferred the Pattern method, where patterns of vibrations indicate different directions, or the ScreenEdge method, where areas of the screen correspond to directions and touching them may induce vibration.

The Effectiveness of Visual and Audio Wayfinding Guidance on Smartglasses for People with Low Vision
CHI '20: Proceedings of the 2020 CHI Conference on Human Factors in Computing Systems

Wayfinding is a critical but challenging task for people who have low vision, a visual impairment that falls short of blindness. Prior wayfinding systems for people with visual impairments focused on blind people, providing only audio and tactile ...
