Gesture vocalizer is a large scale multi-microcontroller based system being designed to facilitate the communication among the dumb, deaf and blind communities and their communication with the normal people. this system can be dynamically reconfigured to work as a “smart device”. in this project, microcontroller and sensors based gesture vocalizer is presented. gesture vocalizer discussed is basically a data glove and a microcontroller based system. data glove can detect the movements of a hand and microcontroller based system converts some specified movements into human recognizable data and display it. the data glove is equipped with the bend sensors. this system is beneficial for dumb people and their hands will speak having worn the gesture vocalizer data glove.
