Arduino-based Tacit Project assists visually impaired

The Tacit Project from Grathio Labs is developing a wrist mounted sonar assistive device for the visually impaired. The hardware includes Parallax Ping ultrasonic sensors mounted in the glove which send distance measurements to an Arduino. The Arduino then activates small hobby servos to vibrate in the glove to communicate the relative distance to objects.

You can find the schematic and source code for this developing project at the Grathio Labs website.

  1. Cool!
    I think there was a similar project once, with the ultrasonic sensors on palms and knees, and vibra-motors in both of these places. Made by someone with lots of bat-related projects (bat detectors, bat downsamplers etc.). But the name escapes me…
