Currently blind people are facing a huge problem when they are in a public place. They have stick in their hand which helps them a bit. But I modified that stick and installed ultrasonic sensors along with necessary hardware in it. Which helps the blind person more efficiently and lets him sense the surrounding up to a radius of 2 meters (which can be extended as per the need) and the device has proven as the best assistant for the blind person as per the real time survey in blind schools.
The TechEye enables the blind person the sense the surrounding and act accordingly. Ones he/she starts using it, they feel no need of human assistance.
My first objective is to provide an easy way of detecting obstacles to blind people, while walking. Secondly I had to design a low cost i.e. economical instrument for the blind people, which they could afford. The design of the instrument should be simple to operate and easy to use for the blind people. The instrument must give fairly accurate results while detecting the obstacles. The instrument must work for a long time on the portable and rechargeable battery. And lastly, the instrument must work long life and to the fullest possible utility.

Its a microcontroller based instrument for blind persons, which will help them navigate while walking. The instrument will help them to detect the obstacles appearing in front of them. This instrument can also produce audible beeps to recognise the direction of motion of the obstacle (in a limited sense), if the blind person is standing still.
