Virtual Talk for Deaf, Mute, Blind and Normal Humans

In the today´s world there are many disabled people (deaf, mute, blind, etc) who face lot of problems when they try to communicate with other. Previously developed devices did not implement any general solution. This paper describes a new method of developing wearable sensor gloves for detecting hand gestures which uses British and Indian sign language system. The outputs are produced in the text format using LCD and audio format using APR9600 module. The hand gesture or the hand signs are converted to electrical signals using flex sensor. These electrical signals are processed to produce appropriate audio and text output. Previously designed devices were not accurate in tracing the hand gestures. The paper employs method of tuning in order to improve the accuracy of detecting hand gesture.
