Abstract:
This project presents the implementation of new hardware for human computer interface (HCI) i.e. mouse and keyboard. We implemented mouse and keyboard in air with the help of accelerometer ADXL 335. The method performs analogue to digital conversion and then it sends the coordinates through serial port. This method is implemented on two separate hardware’s for mouse and keyboard respectively. Complete hardware of mouse and keyboard is implemented on body sensor node (BSN) which consist of three parts sensor, controller, and communication. The reduce size of the keyboard and mouse and free hand movement make it an easy, efficient, and user friendly device the results shows that this device is more compatible with racing and first person shooting games.
