The PS5 DualSense Wireless Controller is a high-spec gamepad that evolves the technology of previous PlayStation controllers. Inside you can find the below technology:
Haptic feedback: Instead of rumble, which means games can send vibrations around the pad to emote how on-screen action would 'feel'.
Adaptive triggers: These can be tailored to gameplay by developers, which means they can become 'tighter' the faster a car moves or loose when a gun runs out of ammo.
Touchpad: This can be used by players to interact with a game in new ways, to swipe across the pad to solve a puzzle, for example. This is similar to the rear touchpad on the old PS Vita.
Speaker: This brings games to life with unique audio and voice acting coming directly from the controller. Used with the above tech the PS5 DualSense controller can make you feel rain drops and hear them hit the pad.
