Sony has filed an interesting patent for a "universal gaming controller," one that could control games on more than one different system.

According to the patent, first unearthed by tech rumor site GoRumors, the proposed controller would work via a touch-sensitive LCD display that would adjust to provide for different consoles' control schemes.

"A game console controller includes a hand-holdable housing and a touch sensitive liquid crystal display (LCD) on the housing," explains the patent.

It continues: "The LCD is caused to present, depending on what type of game console a user has selected, a controller key layout for a first type of game console or a controller key layout for a second type of game console. A key layout includes plural keys selectable by a user to input commands to a game console."

The proposed device would "emulate the controllers" of all "popular game consoles," not just Sony's own, says the patent. It would also be capable of rumble and of sound effects (the Wii remote also uses a speaker).
