Pilot study using an LED version of a depth-based visual aid.
In this short study we tested whether blind and partially-sighted people could use a wide angle (120 degrees) but very low resolution display (96 pixels per eye), to locate and orient towards targets in space as a precursor to walking around independently. We also studied how well controls could learn to use a live depth map on the same low resolution display to navigate a small obstacle course
