Numerical Input Techniques for Immersive Virtual Environments

So far, in the literature, there exist only a few techniques for text input and none specifically for numeric input in immersive virtual environments. Initially, we evaluated two techniques for numerical input, one employing whole hand gloves gestures and a second employing Pinch gloves. While the first technique was proper only for small numbers and for limited use, the second technique performed well in all cases. The Pinch glove technique was revised to allow for hand tracking and re-evaluated with a larger group of users. Statistical analysis showed that the technique is promising and input rate is comparable to other input techniques.
