As sarcastix said.

Microchips which allow you to explore more than the current state of consciousness in terms of gaming (if that even makes any little bit of sense)
such as, big BIG empty rooms which enable you to immerse yourself in a game the chip also links with the organic state of the building and everything object wise is created.

I remember about 6 month ago watching a video of a guy with some plastic and a few wires trailing off, must have been about 4 inch big and it had the properties of a tv in terms of it being capable of video playback. this was on some clear plastic. if technology goes far enough this will be implemented into car windows maybe with a sort of screening effect with infared lighting and a camera to show the road clearer. Speedometer overlay, Call screen with voice. Hell the possibilitys of that idea are endless!
