I dropped by TN Games last week to check our their TN Games' 3rd Space™ Vest. The vest allows you to feel the impact of punches, kicks, bullets and blasts that happen to your character in the game. The vest communicates with compatible games to give precise, 3 dimensionally accurate impact where it happens, as it happens. Impacts from in front of you, you feel in the front. Impacts from behind you, you feel in the back. I also had a chance to check out the helmet which will available later this year. And if your a developer TN Games has made enabling 3rdSpace into game titles easy. A simple, yet customizable, API can be integrated into any game with minimal effort. TN Games provides game developers full support so if you want it check out their site.
