![]() This will allow you to track yaw, rotations of the head in the vertical axis (shaking your head no ), but not pitch or roll. Note: this code does not do stereoscopic 3D tracking: it can only measure rotations that are in the plane of the camera. Combined with Matlab and digital signal processing, it is possible to use this system to (e.g.) adjust signals presented over headphones in real-time so that they appear to remain fixed in space, rather than moving with the head. The Wii remote is a useful tool for researchers: the buttons on the device can be used for recording subject responses, the accelerometers can be used for detecting movement, and the camera can be used to do reasonably accurate motion-tracking of objects such as the head. It has buttons, a 3-axis accelerometer, and an infrared camera mounted on the front. The Wii remote is an inexpensive peripheral for a video game system built by Nintendo.
