LightGuide: Directing Visually Impaired People along a Path Using Light Cues
summary
LightGuide uses a flexible LED strip mounted on a cap to show direction by turning on pixels where the target lies; prototype contains 45 individually-controllable LED pixels and adapts brightness and size to users’ residual vision. Three studies with 12 visually impaired participants compare it to HapticBag and find faster, smoother turns and path following, with a mean steady-state deviation <4°, tighter trajectories on complex routes, and improved indoor navigation safety and efficiency.
