New device helps blind people read without braille
HandSight, a new device has been developed in the US that will help the blind people read by keeping a tiny camera on their fingertip.
The camera measures just one millimeter and sits on the tip of the finger.
When a blind person reads a line of text with his finger, a nearby computer reads it out.
The device can help to read printed materials with many columns of text easily without braille.
The idea is to empower the blind people to carry out their daily activities with the help of technology.
