"I would've really liked to see my character's hands on the screen--so I know
 what they're doing."

 "It was kind of skeletal but the way it works right now is really good for where it
 1S."

 "There was a little sense that you were really there (in the virtual environment)
 like when you move your head and the camera pans back and forth."

4.3.3 Improvements Should Be Made to the System

 The participants suggested a number of areas for improvement. Nearly all

suggested that more body parts be tracked and that interactive facial expressions be

added. One participant from the first study suggested abandoning the gesture tracking for

a system that would aid only in the "blocking" of a scene. The following are the

debriefing responses that dealt with system improvements and the overall idea of the

sy stem :

 "For practice out of rehearsal this could work. It all depends on the level of
 sophi sti cati on."

 "It needs to incorporate more color straps to include the whole body and
 hopefully, facial expressions. I like the idea of the opposite image being that of
 the character instead of the other actor."

 "I would add lots more tracking spots to allow for full body and maybe facial
 movements."

 "There's a lot more that goes into acting that just moving your arms. To make it
 more of an acting experience there would have to be more mobility and
 expression."
