I'm doing research on motion-based controllers and I'm trying to compare the Wii remote to the PS3 SixAxis controller based on the actual information provided by the controller. The Wii Remote doesn't actually provide information about all six degrees of freedom of motion. It provides acceleration data along three local axes, and information about the positions and intensities of infrared lights from the "sensor bar" as seen by the remote. When the wii remote is not pointed at the sensor bar (leaving only the acceleration data), the problem of tracking the wii remote's motion in all six degrees of freedom is under-constrained. I cannot find the corresponding information for the SixAxis controller. Does it live up to its name by actually providing information about all six axes? I'd like to find some source describing the specific motion data that can be read from a SixAxis controller, and if possible some description of the internal hardware used to generate this data. So far I have been unable to find any such sources. Can anyone help?
