Bat-inspired technology helps the visually impaired
NORTH CAROLINA (WKOW) -- Students at Wake Forest University are working on a device to help the blind.
They're using bats as a model.
The device, like bats, uses echo location to determine the proximity of objects.
A sensor in the wristband vibrates as the person wearing it approaches an obstacle.
The closer they get, the faster the vibration.
"It's definitely giving me more vision than I would have expected. With just a small little watch. I definitely think any visually impaired person would be able to benefit from it," said Kathryn Webster, a visually impaired tester of the device.
After three prototypes, students got the costs down to about $35 per watch.
