Hand Gesture Recognition System for Blinds

A real time embedded system is used to interact with an external environment. This external environment may be humans, animals, plants etc. Hand Gesture Recognition System uses a sign language in the form of hand gestures to type the characters on computer screen. Blinds face many problems in their day-to-day life. The most critical of all the problems is their reading and writing. They cannot access computers independently because of difference in the communication medium. They use Braille script for reading and writing purpose, which cannot be interpreted by the existing computers. Also their existing technology is very expensive and not up to the mark. To overcome this problem, we have made a Hand Gesture System for Blinds. The sign language is designed according to Braille script. The six fingers represent the six dots in the Braille. The microcontroller interprets the gestures and sends the data to the computer. The computer recognizes the gesture and prints it on the display. The feature of text to speech is added to the module for error detection and correction purpose.
