Sixense uses the word "tilt" a lot. But I don't know if you understand it's correct meaning.

If I see "tilt left" does that mean Roll or Yaw? It should always mean Roll. But sometimes you have a picture that looks like Yaw.

Tilt means the Y axis moves towards the X-Z plane. It's an important distinction in real life because of gravity, and the tendency of things to slide off a tilted surface and for tilted objects to fall over, unlike when you turn them around without tilting. And it's important in motion control because "tilt sensors" rely on gravity to operate and thus can't measure anything except tilt (like the Wiimote).

Also you talk about tilting the Joystick sometimes, not just tilting the controller. That adds unnecessary confusion.

BTW, Google the word "tilt". No really, it's quite amusing. I did it by accident.

Yep.

For us, tilt_gestures really mean angle_gestures. Rotate the controller along some axis past x angle. You can tilt left, right, up, down, cw, and ccw. I haven't seen a tilt reference for the joysticks. Is that in the SDK?

In real life tilting left means ccw (anti-clockwise as we say in Australia and probably other countries) and tilting right means cw. I'm not sure what the best word to use for yawing left and right a little bit is. Maybe "turn"? But that sounds like 90 degrees. So does "point". Maybe "rotate"? "angle"? There's always "yaw" even if most people don't know what it means yet.

I think descriptions of scripts displayed to the user shouldn't say "tilt left" though, or many users will roll it left.

I think "turn" being associated with 90 degrees is somthing that varies from person to person, for example perhaps people that drive in big cities are more used to 90 degrees turns than people that don't, a race driver might frequently go thru all sorts of turns all the way from almost a straight line to 180 degrees or more depending on what sort of race they are into and for them turn just means not going straight.
