A Muscle-Controlled Virtual Reality System

Researchers create a virtual environment system in which you can pick up fake objects with real effort. Maybe this is how we'll work out in the future: throw on a pair of shorts, strap on our virtual reality goggles, and hit the weights. Researchers from the University of Wisconsin-Madison are doing something like that (although, of course, the weights don't weigh anything) by creating a virtual reality simulator called the Cave Automatic Virtual Environment, or just CAVE, that works by tracking...
