<R02-D> prohibits any device with an exposed laser. I highly doubt that you could argue that the mouse's optics are not exposed.

BTW, a number of teams use accelerometers without any problems. Gravity is either accounted for or ignored, but the accelerometers are reasonable in cost and complexity.
