After settling a patent infringement lawsuit with Immersion (a producer of haptic technology), Sony added the rumble motors featured in earlier DualShock controllers to the Sixaxis and released the new controller as the DualShock 3. Sony originally released the PlayStation 3 with the Sixaxis controller with its namesake ability to detect motion in six directions: three linear axes and three directions for rotation. You can identify this controller by looking on the back for the model number “CECHZC2x.“ Until 2013, the controller was sold in a variety of colors, with some being limited editions or available only with the purchase of a limited edition console. The DualShock 3 was released to the rest of the world throughout 2008. The controller was released in November 2007 for Japanese markets as a replacement to the Sixaxis controller which originally shipped with early PlayStation 3 consoles. The DualShock 3 was released by Sony as a controller for their PlayStation 3 game console.
