I did some usability testing on Microsoft's Sidewinder Strategic Commander, gaming device.
We used Crazy taxi as the testing game and the sound track was so addicting.
We tweaked the side vs rotational forces. It was a blast. Would like to get my hands on one and use it to control a robot. It has forward, backward, right and left twist, plus a bunch of function buttons. The only downside compared to the current crop of game controllers is that its designed to sit on a table.
Let me know if you have used this device.
