The tracking of fingers in two dimensions allows a user to have a pointer interface with which interaction with a computer can be achieved by using the Wii Remote's ability to track infra-red blobs. This project uses one Nintendo Wii Remote, an array of infra-red LEDs and infra-red reflectors which are attached to the fingers. The infra-red array is positioned behind the Wii Remote's camera, enabling the users to simple have reflectors attached to their fingers.

Low-Cost Multi-point Interactive Whiteboards Using the Wiimote

Custom made pens with infra-red lights installed in the tips of the pens are used to track the pens' positions using one Nintendo Wii Remote. This project uses the Wii Remote's two dimensional infra-red blob tracking capabilities. A possible schematic for the pens was suggested:

The pen allows a user to use the momentary switch to turn the infra-red light in the pens on or off.

Head Tracking for Desktop VR Displays using the Wii Remote

This implementation uses the Wii Sensor bar, mounted on the user's head, to track the user's head. The demonstration application renders targets on the screen based on the position of the Nintendo Wii Remotes, resulting in a more immersive experience. The illusion of depth and space that is created by the rendering engine could add to the quality of computer games and other perspective applications.

Design and Implementation of a Hand Tracking Interface using the Nintendo Wii Remote

This project, by Michael Wronski, investigated the use of two Nintendo Wii Remotes to track hands in three dimensions for a specific task - molecular visualization applications. The Wii Remote's camera properties were explored, and a hand tracking interface with six degrees of freedom was implemented and tested. The investigator found that this technique was an acceptable method for the visualization of complex molecules, and could be extended to other Computer Aided Design (CAD) applications.
