HALO For The Visually Impaired

Davide GombaFebruary 23rd, 2011

Happy to discover the HALO project actually won the HUMANA Contest. Check out the other winners. HALO (Haptic Assisted Locating of Obstacles) is a solution for visually impaired people to perceive obstacles around them. Here’s a little description:

I recently watched an episode of Stan Lee’s Superhumans which featured a blind
man who used a series of clicks, like a bat, to echo locate his surroundings. I
got to thinking about other blind people and their ability to navigate freely –
without the use of a guide dog or cane. I came up with the idea to use a series
of rangefinders that would take input from sensors and output feedback to pulse
vibration motors placed on a person’s head. As a person gets closer to an object
the intensity and frequency of the vibration would increase – it’s directly
proportional to the distance of an object. If a region was lacking feedback,
then it would be safe to proceed in that direction.

I call my submission the H.A.L.O. – the Haptic Assisted Locating of Obstacles. I
believe this can serve very useful for the visually impaired to have the freedom
to possibily move about hands-free without the assistance of a cane or seeing
eye dog. Technology has undoubtedly made our daily lives better. By using a few
inexpensive components and sensors, I’ve made a device that will allow the blind
to navigate their surroundings and avoid collisions.
