The PS4 controller also
features a light bar on the top with three color LEDs that illuminate in
various colors. The light bar illuminates to match the color of
characters in a game to offer a simpler, more friendly way to identify
players, even when playing side by side. The light bar also changes
patterns during gameplay to provide useful information to gamers, such
as when a character is critically low on health or has taken major
The PS4 controller also features a built-in speaker and
stereo headset jack. Sony wants to make it easier for gamers to be able
to chat with friends playing online, while hearing sound effects from
the controller in hand.
While previous PlayStation controllers
featured both a "start" and "select" button, the new design integrates
both into an "options" button and adds a "share" button. Again, the goal
is to make it easier for gamers to interact with fellow gamers. Users
can share their triumphs and accomplishments by uploading video gameplay
to Facebook with the "share button." Unlike streaming content via PC,
users no longer have to convert data formats of their recorded gameplay
and can share it with ease, according to SCEA.
The new design
also enables gamers to charge the controller while the PS4 is on standby
or through a dedicated charging station.
Another difference is
that, unlike the PS3 controller, the touch pads on the PS4 controller
are not pressure sensitive. Jabbari said SCEA found that very few games
ever made use of the pressure sensitive functionality.
I don't understand the point of the light bar to be honest. If it's to be used for additional info, whilst I'm playing I'm looking at the screen not the controller! Also, from the looks of the pictures, you can't see the lightbar when holding the controller as if you are playing.
The headset jack may seem redundancy since I'm sure a lot of gamers are using wireless headset. To me, I think it is brilliant. It will become handy if the battery life of the controller is managed properly. The internal speaker is another excellent feature.
I wonder whether PS Vita or next generation PSP can be used as a controller for PS4 just like PSP with PS3. There are a lot of touch capability on PS Vita. I am sure it will open up a lot of in-game feature.

We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
