Controller Designs of the PlayStation.

Released in 1994, the PlayStation control pad was the first controller made for the original PlayStation. It featured a basic design of a D-pad, 4 main select buttons (Triangle, Circle, Cross and Square) and start and select buttons on the face. 'Shoulder buttons' are also featured on the top (L1, L2, R1, R2). In 1996, Sony released the PlayStation Analog Joystick for use with flight simulation games. The original digital controller was then replaced by the Dual Analog in 1997, which added two analog sticks based on the same potentiometer technology as the Analog Joystick. This controller was then also succeeded by the DualShock controller.

Released in 1998, the DualShock controller for the PlayStation succeeded its predecessor, the Dual Analog, and would go on to become the longest running series of controllers for the PlayStation brand. In addition to the inputs of the original, digital, controller, the DualShock featured two analog sticks in a similar fashion to the previous Dual Analog controller, which can also be pressed to activate the L3 and R3 buttons.
On the PlayStation 3 Sixaxis and DualShock 3 controllers, the analog sticks are always enabled. Beginning with the Sixaxis, a 'PlayStation button' (which featured the incorporated PS logo and is similar in function to the Xbox 360 "Guide" button) was included on controllers. The PlayStation button replaces the "Analog" button of the DualShock and DualShock 2 controllers. Pressing the PS button on the PS3 brings up the menu, while holding it down brings up system options.



PlayStation Move is a motion-sensing game controller platform for the PlayStation 3 video game console by Sony Computer Entertainment. Based on the handheld motion controller wand, PlayStation Move uses the PlayStation Eye webcam to track the wand's position and the inertial sensors in the wand to detect its motion, First revealed on June 2, 2009.
Although PlayStation Move is implemented on the existing PlayStation 3 console, Sony states that it is treating Move's debut as its own major "platform launch," planning an aggressive marketing campaign to support it.
