If Dead Space is to be remembered for one thing, it should be its navigation system, where pressing a button triggers an illuminated "path" in the game world showing you your destination. I don't know if it was the first game to do this, but it was certainly the first to do it so prominently/so well.

That system is now working, albeit in a very crude form, thanks to work done by MIT's Media Lab, which using a phone and a projector has built an in-house guide to...everyone's desk.

While the walking around bit isn't as nice as video games have managed, the way it changes when you point it at a door is a great idea that developers should totally steal.
