I visited VR research facilities at ATR, MITI, Fujitsu, and NTT recently. People at ATR and NTT are aiming at "wireless" VR. They showed me some demos of a system that involves video, machine vision and neural network software. A video camera tracks the user. Pattern detection software attempts to track the user's gestures. Neural networks help the system learn the user's gestural repertoire. They have a way to go. Does anybody who is knowledgeable about machine vision and neural networks have an opinion about how well such a system might work? I've played with the dataglove a fair amount, and unless they have come up with something startling and new, the glove does NOT simulate textures. Margaret Minksy at Media Lab and UNC has been using a force-reflective joystick with her own software that does a remarkable job of simulating texture. But it is a joystick, not a glove.
