Rather than having to switch controllers to play your PS3, 360, or Wii, Sony is considering a future where you can play all three from a single universal controller psp games.
According to the patent, the device would consist of a regular controller-shaped housing with physical shoulder buttons and a touch-sensitive LCD screen on the front. Using a screen instead of actual buttons means the shape and layout of the buttons displayed can be changed to fit whatever you were playing – even allowing you to switch between a keyboard and the controller.
More surprising yet, the patent goes on to list Amiga, Jaguar, Sega, and Turbographics as controller layouts that could potentially be used. A device like this one could be extremely useful for emulation enthusiasts and owners of multiple consoles, assuming they can get over the pain of having to use touch-screen controls.
