Wearable device helps visually impaired avoid collision

(1/1)

kaushik.swe:
 Researchers have developed a wearable device for the visually-challenged people that can help them avoid a collision.

People who have lost some of their peripheral vision, such as those with glaucoma, or brain injury that causes half visual field loss, often face mobility challenges and increased likelihood of falls and collisions.

"We developed this pocket-sized collision warning device, which can predict impending collisions based on time to collision rather than proximity," said paper co-author Shrinivas Pundlik.

The findings are published in Investigative Ophthalmology and Visual Science (IOVS).
