Well there are commercial ones that are already on the market that can do that now.... unfortunately the starting price is around $25,000..... Personally, I'd love it, would make everything that much easier in the non-animator stuff, but very rarely does the hobbist have enough money to throw around 25K on a whim.... That and with a telemitry suit you couldn't pose things like flight or falling very well without some interesting use of peterpan wires. At any rate was thinking of something more along the line of what a graphics tablet is to a mouse, rather than what a vertual reality system is to a mouse.
