Feasibility Test of Virtual Reality Obstacle Detection for Low Vision Walking

Hemianopsia Clinical Trial

Official title: Monocular Visual Confusion for Field Expansion

Status Recruiting

Clinical Trial Summary

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.

Clinical Trial Description

The investigators will develop a new pedestrian hazard detection test and conduct a single arm interventional clinical trial to evaluate simulated low vision assistive devices in a sample of field loss subjects. Pedestrian detection performance with and without field expansion information will be tested and compared. The study will include 1 to 4 visits (each 2 to 4 hours) depending on the number of trials and experimental conditions (e.g., with and without simulated assistive devices) the subject is comfortable completing. The time between visits may vary depending on scheduling constraints and availability. During each visit, the subject will complete a series of simulated collision avoidance trials in VR requiring the detection and natural avoidance of a colliding pedestrian (alongside non-colliding pedestrians) while physically walking through an empty corridor. The study will be considered minimal-risk since there will be no physical obstacles that present actual collision risks. ;
