ACCELEROMETER BASED WIRELESS AIR MOUSE USING ARDUINO MICRO-CONTROLLER BOARD

Abstract

With the day to day advancements in technology, the interaction between the human and the digital world is diminishing. Lot of improvement has taken place in the mobile technology from button keypads to touch screens. However the current PCs still need a pad to operate its mouse and are wired most of the time. The idea is to develop a wireless mouse which works on the hand gestures of the user without the need of a pad making an effortless interaction between the human and the computer. The implementation is done using a sensor named accelerometer to sense the hand gestures. Accelerometer is a motion sensor which sense changes in motion in any of the three axes. In here the accelerometer will be at the user’s side, attached to the hand to sense the movement and gives the output to a micro-controller to process it. Necessary modifications are done by the microcontroller to these values and are transmitted through a RF module to the PC. At the receiving end a mouse control program which contains functions to control the mouse reads these values and performs the necessary action.

Existing System

Bluetooth and Zigbee.

Proposed System

The proposed system architecture uses accelerometer as a sensor to detect the motion. Accelerometer is interfaced to a microcontroller, Arduino in this case. The microcontroller does the necessary processing on the sensor data and transmits it through a wireless transmitter module. The wireless receiver receives the data and feeds it to the computer through one of the interfaces. The application running on the PC analyzes the received values and perform the necessary action on the mouse pointer.
