Wireless Computer Mouse Based on Finger-tip Tracking

Abstract

Human computer interaction (HCI) is the study of how humans interact with computer systems. Using the computer mouse for a long time results in damaging the arm muscle thus, producing pain in the human body. In addition to that, people who lost their hand due to any accidents and substitute it with an artificial arm cannot use the computer mouse in a proper way because of their delay in controlling fingers. In this project MATLAB was used to design a program to add a vision capability to the computer operation system (windows), so as to control the operation of the computer mouse in a PC screen using finger-tip. A webcam is connected to the computer to take an image of the view in front of the computer. Three finger-tips are used with different color; red, blue and green. The red finger-tip is used to move the mouse around the screen, the blue to perform a mouse left bottom click, and the green to perform a mouse right bottom click.
