I will explain how the system works The gloves capture the hand movements and transmit the movement pattern, the sig n itself to the mobile device. Then our application matches the incoming pattern  of the hand movement and displays the corresponding output to the screen. The first part of the projet is capturing the hand movements. This is done compl etely with sensors on the gloves. Flex sensors captures finger movements and con tact sensors detect contact betweeen fingers. accelerometer and gyroscope captur e angular position of the hand in space. These sensors gather all the values and  transmit it to the mirocontroller. The microcontroller converts the data and th en transmits it to the mobile device through the bluetooth shield, tthats how th e sign are being recognized to the existing patterns. Then using android text to  speech the sound is played by the mobile device.

The gloves consists of flex sensors, accelerometer, gyroscope and contact sensor s. The flex sensors and contact sensors form voltage divider circuit. These sens ors capture the hand movements and transmit the movement pattern to the microcon troller. The arduino microntroller is programmed to transmit the output pattern or voltage values to the mobile device using bluetooth shield. To get the desire d out beingput, the voltage values are tested repeatedly using arduino serial mo nitor . The android application will process the transmitted volatage values and  is being compared to the programmed values of the application. Precise hand mov ements is important to get the desired output of the hand signal. Then using the  android text to speech, the sound is played by the mobile device.

Flex sensors are placed on the glove to measure the bent resistance variation of  each finger. Contact sensors are positioned between fingers. Accelerometer and gyroscope are positioned on the palm side to precisely capture the hand angular movements. The sensors are connected to the voltage divider circuit to vary the voltage values produced by the sensors The movement pattern captured by the sensors are transmitted to the microcontrol ler. The microntroller is programmed to transmit the output pattern or voltage v alues to the mobile device using bluetooth shield. To get the desired output, th e voltage values are tested repeatedly using serial monitor . The android applic ation will process the transmitted volatage values and is being compared to the programmed values of the application. Precise hand movements is important to get  the desired output of the hand signal. Then using the android text to speech, t he sound is played by the mobile device.
