Human Head Movement Based Voice Enabled Wireless Communication

Human Head movement based voice enabled wireless communication system is a translator system of human head gestures pointed to physically challenged peoples. This system helps them to do their purposes without any dependents. The user can wear this device to head and with simple head movements he/she can request the basic needs like water, food or medicine by using mems technology. User can also control the electrical devices like light and fan with the help of head movements. In transmitter section a microcontroller takes the readings from MEMS sensors (accelerometer) which is wear on head. Then the controller matches the values with pre-settled one via program and produces the corresponding command via ZigBee communication. In receiver section a ZigBee transceiver access the command and gives to the microcontroller interfaced with it. An auto record/playback chip with a speaker is connected with the Receiver microcontroller. We should record the essential voices in voice IC which are frequently used in daily life. According to the commands from the transmitter section corresponding voice played in receiver section automatically. (via program in the Receiver-microcontroller). An LCD provides a visual output. The device ON-OFF is also possible via the commands from transmitter side. This device is portable.. User can wear it to his head like a band and can operate it by tilting the MEMS sensor. Here we are using pic 16f877A microcontroller..
