A research division of electronics manufacturer Philips, Surrey's Philips amBX Group, has
devised a technology and scripting language that will use situations in video games to create actual effects in the real world. The system uses the environments of a video game to trigger various components surrounding the gamer--fans, different-colored lights, heating devices, and so on. The point is to make the entire room representative of what's going on in the game, to heighten the game's immsersiveness.
This means that in a game the lights in your room will match up to the environment you are gaming in. E.g. Green for jungle and blue for the ocean. Strobes of white light could simulate a lightning storm and a burst of air from a fan could make huge jumps feel more realistic.
Seems...interesting. Philips claims to be currently discussing the technology with developers. The company plans to launch its product next May, which means we'll probably see it at E3.
