Hand-Mounted Sonar For the Blind

Posted by samzenpus on from the daredevil-approved dept.

GeekTech.in writes "The Tacit, a wrist-mounted sonar device with haptic feedback, is like strapping a bat to your wrist to help you see. It makes use of two sonar ping sensors to measure the distance to the nearest obstacle. The relative distance to an object is then fed back to the user using two servos which apply pressure to the back of the wrist."

    And it should've, damnit.

    Keep reading for more information, build notes, parts list, schematics, and code. ...

    Important Note #2: The circuit and software is released under a Creative Commons BY-NC-SA license, which I think of as a "Don't be a jerk" license. In short: Make it, learn from it, teach it, improve it, modify it. Just share what you do, give credit, and don't sell any without contacting me first.

    PARTS LIST?!? CIRCUIT INFO?!? WOOOT! Now this looks like a damn fun toy.

    You've obviously never heard of Ben Underwood (http://en.wikipedia.org/wiki/Ben_Underwood#Ben_Underwood), whom is often listed among the top ten contemporary inspirational people. Not only was he able to "see" using echolocation via clicking noises with his tongue, he excelled at tasks such as mountain biking. And he is not the last blind person able to do so.
