Biology students at Wake Forest University have developed a device to help the visually impaired, and it’s largely based on bats. The students studies echolocation, the ability of bats and moths to use their natural sonar capabilities to navigate darkness. 

Then, they tried to come up with a device that would harness that biological sonar.   They invented a wrist watch device, And they asked a schoolmate, Kathryn Webster, who is visually-impaired, to test it out. 

Webster, a sophomore and Wake Forest’s only blind student, says  “I can’t see out of my left eye. I have low vision in my right eye. But it’s not
usable vision. I can see colors, shape, light, dark”
Webster says she lost her vision six years ago, “So once I came to Wake Forest, I knew I had to resort to something. So I decided to get a dog. And I wasn’t a huge dog person prior to getting him, and now I can’t imagine my life without him.”
Kathryn’s black lab guide dog Enzo helps her navigate around the campus.  But this new wrist device is helping, too.  It uses sonar technology to let Webster know when she’s getting close to a fixed object, like a door.  

Jack Janes, part of three student team who created the device, says, “It’s very exciting to be able to produce a device that could have a meaningful difference in somebody’s life.” The student team made it as part of a class project, inspired by a professor who’d spent years studying bats and their ability to echolocate in the dark……
