Echolocation Hat for the Blind
Posted on May 16, 08 05:53 AM PDT
Check out this interesting invention - an echolocation hat that is meant for blind folks or those who have extremely poor vision. It uses the theory of echolocation (bats navigate their way around with this principle as well) that helps blind people find their way around. This ultrasound device could potentially and drastically shorten the amount of time required to learn the art of echolocation, as this time round it will be done electronically. Hopefully the final version will have some sort of low-battery life indicator.
