So there's the Wiimote which detects real-time motion, the PlayStation Eye which recognizes real-time images, and the PIP which recognizes... real life stress? This little doohickey from Vyro Games is a new game input device that measures the electro conductivity of your skin to measure your stress and uses the data to play a game.

It might sound a little masochistic to play a game using stress, but the PIP - or Personal Input POD - was actually developed to help control it. It trains users to control their stress level by playing a game that can only be won by keeping their cool. The more you stress out, the more likely you lose.

PIP has been developed to work with any device with Bluetooth, and that includes the PC, mobile phones and even compatible consoles. Games are currently in development for the device: so far there are only three games available for the gadget, but they all look pretty fun.

One game has you racing a dinosaur who won't move if you stress out. Another game is like a mood ring: the device measures your stress and an image's weather will change depending on your stress levels. Last but not least (and maybe the most useful) is a lie detector.
