The Silence Breaker recognizes the gestures of the dump and generates voice signal corresponding to it. In the case of deaf, the device captures the oral sounds and converts to gestures which will be displayed on the user’s hand using Micro projectors.
Silence Breaker has three modes of operation:
1. View mode- for deaf
2. Voice mode- for dump
3. Hybrid mode- for both deaf and dump
Features:
1. 3 modes of operations are applicable
2. Different …show more content…

Block Diagram
When the device is used by the dump, the camera contained in the device recognizes and tracks the user gestures using computer vision based techniques. The mobile computing device processes the information. It performs the matching function to find the meaning of gestures. After finding a match the corresponding voice signal is send to Bluetooth headset through transmitter, otherwise there will be no action.
In the case of deaf, the words pronounced by the normal person will be captured using microphone and send to Bluetooth receiver embedded in the mobile computing device. The voice will be processed and the matching gesture will be identified. These gestures are projected by the Micro projector as visual information on the user’s hand.
The Micro Controller AT89C2051 in the Mobile computing device is used for the purpose of comparison.
Features of AT89C2051:-
• 2 K Bytes of Reprogrammable Flash Memory
• 1000 Write /Erase cycles
• 128x8-Bit Internal
