Collision Warning Device for Blind and Visually Impaired

Glaucoma Clinical Trial

Official title:
Wearable Collision Warning Device for Blind and Visually Impaired: Clinical Trial (As Part of: 'Development of a Vision Assistive Device for Veterans With Traumatic Brain Injury-Associated Visual Dysfunctions')

Clinical Trial Summary

This study evaluates a novel collision warning device to help people with severe vision impairment or blindness avoid collisions with obstacles. The main hypothesis to be tested is that the device reduces the number of collisions with obstacles in everyday activities.

Clinical Trial Description

Participants with blindness or severe visual field loss (hemianopia or tunnel vision) will be trained to use a collision warning device that alerts them to impending collisions. Participants will use the device at home during everyday mobility for about 1 month. The device is designed to supplement existing mobility devices, such as a long cane or dog guide. The device will provide warnings about potential collisions with mid- or high-level obstacles (which are typically not detected by a long cane). ;
