The wiimote uses only the one accelerometer. Once you factor in that
gravity is always down you can use it as a tilt sensor as well. The
IR sensor was added for accurate screen pointing as very hard
movements exceed the limit of the accelerometer and it does not have
enough resolution anyway.
Also note the IR camera and accelerometer are $3/ea. This is why
Nintendo was ok with using Bluetooth w/o special encryption measures -
it has a huge profit margin anyway!
