Ken Kutaragi recounted the designing of the controller: The PlayStation 2 console is backward-compatible with the original PlayStation controller, with limited function due to a lack of analog sticks and pressure sensitive buttons. In an interview with Teiyu Goto, designer of the original PlayStation controller, he explained what the symbols mean: the circle and cross represent "yes" and "no", respectively (which explains their common use as "confirm" and "cancel" in games this layout is reversed in Western games) the triangle symbolizes a point of view and the square is equated to a sheet of paper there to be used to access menus. Using the simple geometric shapes of a green triangle, a red circle, a blue cross, and a pink square ( △ ○ × □) to label its action buttons rather than traditionally used letters or numbers, the PlayStation controller established a trademark which would be incorporated heavily into the PlayStation brand. To compensate for the less stable grip from shifting the middle fingers' placement to the shoulders, grip handles were added to the controller. Intended to update the gamepad for navigating 3D environments such as the ones PlayStation was designed to generate, the concept behind featuring shoulder buttons for both the index and middle fingers was to implement two-way directional depth controls using the two sets of buttons. Design īased on the basic button configuration established with Nintendo's Super NES Controller, the PlayStation controller added a second pair of shoulder buttons for the middle fingers. The original version (model SCPH-1010) was released alongside the PlayStation on December 3, 1994. The PlayStation controller is the first gamepad released by Sony Computer Entertainment for its PlayStation home video game console. For other controllers, see PlayStation § Controllers. For example, in a racing game, you might feel a jarring vibration as your car slams into the wall.This article is about the original controller. This feature provides a tactile stimulation to certain actions in a game. In games that support them, analog features like these allow for amazing control over gameplay.Īnother feature of the Dual Shock controller, actually the reason for its name, is force feedback. By monitoring the output of each potentiometer, the PSX can determine the exact angle at which the joystick is being held, and trigger the appropriate response based on that angle. Resistance is increased or decreased based on the position of the joystick. Current flows constantly through each one, but the amount of current is determined by the amount of resistance. Two potentiometers (variable resistors) are positioned at right angles to each other below the joystick. These joysticks work in a completely different way from the buttons described above. Newer Dual Shock PSX controllers have analog joysticks on them, as well as the standard buttons. If you're playing a game in which pushing down on the directional pad causes the character to crouch, a similar string of connections is made from the time you push down on the pad to when the character crouches. There is also a metal disk under each arm of the directional pad. The CPU compares that data with the instructions in the game software for that button, and triggers the appropriate response. The controller senses that the circuit is closed and sends that data to the PSX. While the metal disk is in contact, it conducts electricity between the two strips. A small metal disk beneath the button is pushed into contact with two strips of conductive material on the circuit board inside the controller. In essence, each button is a switch that completes a circuit when it is pressed.
