Remote system control via infrared head trackingSynopsisBy placing points of infrared light on either side of the users head and viewing it through an infrared camera it is possible to find the relative position of the users head. The Wii Remote is an inexpensive piece of hardware which contains, among other things, an infrared camera and an image processor which transforms sources of infrared light to point data on board the controller. The Wii Remote communicates with its home console using the Bluetooth HID protocol which means that by simply pairing a remote with the computer we can receive this infrared point data directly and process it further in MATLAB for the purpose of controlling remote hardware such as a camera mounted to a stepper motor.

ImplementationMany infrared goggles contain white LED's on either side of the wearers head. By simply replacing these with infrared LED's we can track the relative motion of the users head along the Tait-Bryan rotations (pitch, roll, and yaw). To receive point data from the Wii Remote a DLL has been written in C++ to act as a bridge between MATLAB and Brian Peek's WiimoteLib (http://www.brianpeek.com/blog/pages/wiimotelib.aspx).
