Summary:
U.S. Patent No. 6,231,444 (the ‘444 Patent) is the patent that relates Sony’s DualShock controller. The DualShock controller featured two analog sticks and two integrated vibration motors. The ‘444 Patent mainly relates to the two analog sticks and their functionality. Most developers build a game's control scheme around a dual analog controller. Computers use to dominate the first-person shooter genre because the mouse and keyboard provided better controls to the players. Dual analog sticks made consoles a more viable option for first-person shooters because developers could separate the aim and movement inputs. The aim could be on the left stick and player movement on the right stick. It took a while for developers to maximize the potential of the dual analog, but now every console uses a dual analog controller.


Abstract:
An operating device used in a game machine for playing a television game includes a main body portion of the operating device and first and second grip portions protruding from one side on respective end parts of the main body portion. A first operating unit is mounted on one end of the main body portion and a second operating unit is mounted on the opposite end of the main body portion. The first and second operating units are provided with a plurality of thrusting operators protruding from the upper surface of the main body portion and a plurality of signal input elements actuated by the thrusting operators. A third operating unit and a fourth operating unit are arranged facing each other on the proximal ends of the first and second grip portions. Each of the third and fourth operating units has a rotation member and a plurality of signal input devices actuated by the rotation member. When the first and second grip portions are gripped, the third and fourth operating units can be manipulated by a thumb finger of a hand gripping the first or second grip portion. The operating device further includes vibration imparting mechanism for imparting vibrations to the user's hands.

Illustrative Claim:
1. An operating device for a game machine, comprising: a main body having front and rear sides and upper and lower surfaces; first and second grips protruding at spaced positions from end parts; a first operating unit mounted in said main body adjacent one of said spaced positions, said first operating unit having a plurality of first thrusting operators protruding from said upper surface of said main body and a plurality of signal input elements each for generating a signal when a corresponding one of said first thrusting operators is depressed; a second operating unit mounted in said main body adjacent the other one of said spaced positions, said second operating unit having a plurality of second thrusting operators protruding from said upper surface of said main body and a plurality of signal input elements each for generating a signal when a corresponding one of said second thrusting operators is depressed; and third and fourth operating units arranged on said rear side of said main body, said third operating unit being positioned adjacent said first grip and said fourth operating unit being positioned adjacent said second grip so that said third and fourth operating units confront one another, said third and fourth operating units each having a rotation member and at least one signal input element for generating a signal in response to an operation of said rotation member.
