It seems it detects 2 axis of movement and 3 dimension.
maybe one axis of movement, since it only registers side to side movements? Imagine turning m_pitch to 0 in quake. That's basically how much freedom of motion this ball seems to have.
I guess pitching (or tilting downwards/upwards) would add engineering problems, since the front of the controller would also activate the movement sensors.
Anway, from a neuromuscular perspective, perhaps being able to register roll independently of downward movements would be a problem: people might like to actually make downward movements by flicking their wrist since it takes less energy and has more precision than moving your whole arm downward.
Imagine in quake that you had to move your whole forearm to control the mouse in order to aim, and that if you used your wrist to move the mouse, the game would respond differently. Would make fast twitch movements kinda impossible.
