That's what I heard someone saying when I walked by 3DV Systems’ booth. Their 3D camera lets you control games with movement, just like the Wii—except you don’t need to hold a controller. Watch the guy boxing in this video: He’s swinging his arms just like he would in a boxing ring, and his on-screen character moves exactly as he does. The trick is a web-cam-sized camera, placed near the TV, that sends out invisible infrared rays and times how long they take to bounce back. This captures 3D information that shows where each part of your body is at each point in time, and the game uses this location and position info just like a Wii game would. Right now 3DV is in talks with companies about making and selling the product, hopefully for under $200.
Watch for more details on the tech in an upcoming issue of PopSci, and in the meantime, check out the video after the jump. —Lauren Aaronson
