The car has a camera mounted atop its hood and video feed can be seen on the PSP. "

The car and PSP would communicate via a wireless link. 

You may be wondering why anyone would want a camera on top of his or her remote controlled car. Well, according to the patent, “a user may control the car… so as to spy on their friends… then upload the stored video images to a website.”

Among other specifications, the car has the ability to create “augmented reality zones,” which are areas outlined with virtual markers that players physically place. If a car leaves the zones, it freezes, safely allowing one to build a racetrack near, say, a flight of stairs.

This is only a patent and most patents don’t see light, so don’t go planning any Christmas lists just yet. Still, it's definitely an interesting direction Sony could go with its PSP if they followed through.
