Previous E3 expos have introduced video games controlled by your feet (Dance Dance Revolution) and your voice (Karaoke Revolution). Now get ready for AntiGrav, the game you play wearing fluorescent gloves. Via the EyeToy, a mini-camera that plugs into PlayStation 2, AntiGrav (due this fall from Harmonix) senses your glove movements and uses them to control a futuristic hoverboarder--ducking, doing tricks and grabbing bonus points. Previous EyeToy games used your camera image onscreen, which meant you had to stand in direct light. But since AntiGrav needs to see only those gloves, you can play in just the glow from the TV.
