New consoles typically mean a new controller and, every now and then, said new controller is a somewhat radical departure from its predecessor (See: Every console controller Nintendo has ever released). This happens to be the case for the DualShock 4, the details of which Sony has now shared in a brief introductory video.
While the PlayStation 4's controller doesn't destroy the mold, it certainly does a good job of breaking it. For starters, the controller has a light bar on the front, similar to what you see with the PlayStation Move, that will work with the console's camera to keep track of where the player is in the room. There's also a headphone jack at the bottom of the DualShock 4, as well as a built-in speaker that should give developers some fun new ways to interact with the player.
The typical Start/Pause buttons have been removed, their functions simply pegged to the PS and Options button. Also, the back triggers have no been designed to actually look and feel like triggers. Can I get an amen?
Easily the most noticeable difference, however, is the addition of a small touchscreen located smack-dab in the center of the controller. I'm certainly interested to see how that screen will be utilized by developers, but I'm not yet convinced concerning its inclusion.
Finally, there's the Share button, which received a lot of attention during Sony's PlayStation 4 reveal event in February, allowing players to easily share their gaming experience with friends, create videos and screenshots, etc.
All of these features have been shown off in a new video featuring various Sony designers. It's all very zen. Seriously, you could probably listen to this bad boy as a lullaby to carry you off to sleep.
