Gesture means physical motion or simply it is one kind of expression. Nowadays computer plays major impact on our daily life. Today all around the world is directly represented by personal computer. Keyboard and mouse are two important input devices of any personal computing system. However, we are going to control PC or laptop by gesture. The main function behind this system is to control computer through tilting of head and blinking of eye to obtain two major modes of PC, one is keyboard mode and another is mouse mode. Gesture control computer is an interface system that would allow a similarly paralyzed user to interact with a computer with almost full functional capability. That is, the system operates as a mouse initially, but the user has the ability to toggle in and out of a keyboard mode allowing the entry of text. This is achieved by using the control from a single eye, tracking the position of the pupil for direction, and using blinking as an input. As detection of eye motion proved too challenging, we built an accelerometer based tilt detector to determine he
[1] Output on Hardware using potentiometer Obtained output using AT mega-32 Development Board, interfaced accelerometer (sensor) with on chip ADC of AVR. Displayed result on eight LEDs. While we move accelerometer then it will sense gravity of earth and generate analog signal which is given one of the I/P channel of ADC AVR afterward it will convert the analog data and generate binary bit, LEDs will glow as per 0 bit as they are connected in common anode configuration. [2] Interfacing Accelerometer with AVR and 16x2 LCD Accelerometer is a tilt sensor, which measure acceleration. Here we have used 3- axis accelerometer having three analog o/p pin. This three analog pins are x,y,and z , this pins are connected to ADC0,ADC1 and ADC2 pin of avr respectively, as AVR has on-chip ADC and PORTA is designate as an ADC port ADC converts all three analog signals into digital samples by mapping of analog signal and its o/p displayed on 16x2 LCD, which is connected in 4-bit mode. [3] UART Output Interfaced AVR AT Mega -32 development board along with PC using serial cable bud rate has been sate 9600 in programming, after setting ‘Flash Magic`s ’ terminal tool at 9600 bud rate switch ON the Dev. Board. It shows “CKPCET” string on PC`s screen.
