Abstract
This report presents the project of finger-based computer mouse by using a game controller of Nintendo Wii, Wiimote. This project is focusing on developing an alternative computer mouse which is cost-effective, real-time application, user-friendly and can be used at a further distance from computer. It consists of a hardware setup for sending infrared (IR) light to Wiimote and a Graphical User Interface (GUI) that is built by using Microsoft Visual C++. A C++ library, “WiiYourself!”, is being used to obtain three IR dots’ coordinates from Wiimote, which are implemented for computer mouse’s functions. From the experiment, it is found that the user can successfully move the mouse pointer and perform clicking at a maximum distance about 2 meters away from Wiimote, which is good for presentation. The main drawback is the batteries of the glove with IR LED need to be changed after four hours of usage as its voltage dropped to a level that would worsen its performance. Besides, as the user used this system for long time, the users hand started to be uncomfortable. At this moment, the user can successfully move and perform clicking just like a conventional computer mouse with some limitations.
