Researchers Develop $60 Sonar Watch To Aid the Visually Impaired

Taffykay writes Biology and computer science students and professors at Wake Forest University have teamed up to develop a device to assist the visually impaired. Following the principles of echolocation used by bats and moths, the interdisciplinary team has developed a watch-like unit that allows the wearer to navigate their environment using sonar. To make the project even more remarkable, all the parts and materials for the prototype cost less than $60.

Mine's more like a flashlight, and vibrates based on distance. I have an idea for something better, but haven't had time to work on it.
