User Interfaces that we design should be as easy and seamless as possible. The student will often have to step to different parts of the technique he or she is studying, vary the speed, change some options or what have you, and this will need to be accomplished as quickly as possible. As before, interfaces which we will test are in red, those that we would like to get to are in black.

Virtual Buttons
Display a set of buttons for the student, in virtual reality, which the student then "presses" in some way.

Haptic Buttons
Take the set of buttons from above, but give them a haptic component. This can be done to three varying degrees:

1. Static haptics - display the buttons where a real life static object is. The student feels something there when he or she presses the button
2. Limited dynamic haptics - give the student some kind of haptic feedback for his or her choice. This could be something like mounting foam pads on a board so that the student presses into the foam. This need not be reflected in the visuals
3. Tracked haptics - create a set of buttons that respond the same in the physical and virtual world. When the student presses the physical button, the virtual button also moves.

Posture Matching
We create a variety of special postures which the student can perform and which have meaning to the system. A very nice example of this is that if the student wanted to start at "White Crane", he or she can move into the White Crane position and the form would start there

Speech Recognition
We would do man-behind-the-curtain style speech recognition to test initially. The student would shout out a voice command and the operator would press the appropriate button

Floorpie Menu
We could display something like a pie menu on the ground, or coming up in space, which would let the student choose an option by walking into the appropriate choice or by simply pointing at it.

Gesture Recognition
The dynamic counterpart to Posture Matching. This could be technologically complex because most work on gesture recog. has been done in 2D, and extending to 3D may not be trivial.

Physical Input Devices
We could create some wearable input devices that are unobtrusive and always available to the student. There are some serious technology issues here, for example building the devices and transmitting there signals wirelessly
