As such, it is possible to calibrate this device using normal camera calibration techniques so that it can be used for tracking or human interfacing in a virtual environment. Camera calibration is an active area of research and there is a wealth of software available to perform the calibration e.g. ArToolKit and Matlab. Camera calibration typically requires at least five images which contain multiple grid points from which a matrix of camera parameters can be estimated. This paper proposes a method of calibrating the Wii Remote's IR camera by building up 24 calibration points from the 4 viewed infrared LEDs for a single viewpoint of the IR camera. This is done by moving the 4 LEDs in a known sequence using highly accurate PA-10 robotic arms. The camera calibration matrix parameters obtained from this method are presented.Categories and Subject Descriptors (according to ACM CCS): I.3.4 [Computer Graphics]: Virtual device interfaces; I.3.7 [Computer Graphics]: Virtual reality; I.3.8 [Computer Graphics]: Applications; I.4.1 [Image Processing and Computer Vision]: Camera calibration; I.4.8 [Image Processing and Computer Vision]: Tracking;
