Researchers Develop $60 Sonar Watch To Aid the Visually Impaired

Posted by samzenpus on from the daredevil-watch dept.

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.

  1. Hah, I had the same idea. by bigattichouse · · Score: 3, Interesting

    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.

    Echo location isn't about removing the blind persons need for a cane, even with people who are good at it are still recommended to use a cane because things like grates, poles, or holes do not work well with echo location. As the sound passed threw it and back.
    What it does mean is with the aid of a cane and the watch they will be able to move more quickly with more assurance that there isn't something big going to be in the way.

    If something is so important that you feel the need to post it on the internet... It probably isn't that important.
