There about 40 to 45 million blind people in the world, than the available affordable blind devices in the market today.
Each of these devices have both advantages and disadvantages, but each aim to help the blind avoid obstacles.
The latest is the new optical radar system, developed by two engineering students of Ben-Gurion University of the Negev. As part of their curriculum, these students have created an inventive optical radar system that aids the blind move around obstacles.
This optical radar system uses a computer (as the brain), two video cameras and a laser light source to alert the blind of obstacles with signals which can be heard audibly.
The device perceives obstacles, including those above the head, by scanning the extent of its surroundings, taken from two diverse angles which is like how the human eye works.
This project was exhibited together with the other 90 student projects of BGU students in their Annual Conference of Projects in the Department of Electrical and Computer Engineering.
