"With different versions for racing and first-person shooter titles, the idea is to make you feel gunshots, kicks, punches, acceleration, deceleration, crashes and general real-life sensations you play games to avoid.
It does this by inflating pockets of air around the body or little cells on the head to give you a jolt now and again. Quite cleverly it can inflate partially or blow air over your ears to simulate a near miss.
So far only the first-person shooter vest is available to buy for USD 169 in camouflage or tactical black colours. Currently it only works with Call of Duty 2 or TN Games title Incursion, but has Valve and id Software titles in its sights. Phew."
