Touch, LEAP, whatever controls have the basic problem of decoupling the eyes and body. The problems with lag between what they can deliver to the eyes and our bodies movements is a horrendous problem and the root of simulator sickness. Lag is being overcome. But, we haven’t even started talking about motion calibration.

Motion calibration is about how fast and precisely the avatar can follow your physical movements. Lag greatly complicates the problem. We see examples of that in SL when network lag takes ping times to 500+ms. We can no longer precisely turn our avatar with a mouse movement. We guess at how long to press an arrow key to turn or move the avatar to where we want to go. Fortunately avatars don’t bruise. Imagine what the Movie Surrogates would have looked like if those avatars had SL’s lag. Avatars would have been walking into walks, each other, and driving would have been an insurance company’s horror film… avatar bumper cars…

I think sensory replacement technology is going to be part of the solution for using VR. For everyday travel, work, and social interaction augmented reality has more answers and is more realistic for a physical body moving in the physical world. I expect the fields to develop and be adopted for the human uses they best suit.
