Intel Labs and the U.S. Army have signed an R&D agreement to dramatically improve virtual reality tools used to train troops. The work could allow thousands of soldiers to concurrently participate in virtual training exercises -- a 10-fold increase over the current technology. Eventually, the technology could aid other professions including first responders working on disaster simulations. It can also help model that massive paintball war you're planning this weekend. Intel research scientist Huaiyu Liu has additional thoughts on this technology.
