Vyro Games demonstrated its egg-shaped personal input pod, or "PiP," the device used in Vyro’s casual games for Bluetooth phones. You hold the PiP in your hand, and it measures biometrics like skin moisture to determine how relaxed you are. Vyro has developed a series of 1-on-1 and single-player mobile games to promote relaxation — the less stressed you are, the better your chances of winning. The Vyro representative on stage couldn’t relax enough to get his virtual dragon to fly around on the screen. More pics after the jump. Photo: Brian Solis via Flickr.
