Gi - PS4 Controller is a revolutionary evolution of Sony’s famous DualShock technology. The core design of the PS4 controller is similar to prior Sony DualShock controllers hailing all the way back to the original PlayStation. Originally, the PlayStation featured a basic controller with a D-Pad, four buttons split between the left and right shoulders, a select/start button and the iconic Sony button set (Square, Triangle, Circle and X). Eventually, Sony released the Dual Analog controller for the PS1, which added two analog joy sticks to the set up, but the Dual Analog soon phased out of existence as Sony introduced the first DualShock controller. The DualShock featured two vibrating motors that responded with vibrations to the action taking place on screen. This DualShock technology has become the signature feature of Sony systems ever since.
