Feasibility Test of Virtual Reality Obstacle Detection for Low Vision Walking

Running, not enrolling · Not applicable

Conditions studied: Hemianopsia, Homonymous Hemianopia, Tunnel Vision, Visual Field Defect, Peripheral, Visual Field Constriction Bilateral, Visual Field Defect Homonymous Bilateral

In brief

The investigators are developing a new test of pedestrian hazard detection in virtual reality (VR) head-mounted display (HMD) headset, which shows virtual oncoming pedestrians in 3D while subjects are walking in real-world environment, for evaluation of visual field expansion to improve mobility in people with visual field loss.

• In sufficiently good health to be able to complete sessions lasting 2-3 hours
• Able to understand English
• Able to give voluntary, informed consent
• Able to independently move short distances
