Facebook's next mission: taking over your smartphone screen.
The social network unveiled Facebook Home, an operating system that deeply integrates features of the service, at an event at its Menlo Park, Calif., headquarters.
"Our phones are designed around apps and not people," says Facebook CEO Mark Zuckerberg. "We want to flip that around."
Home features an interface focused on the user's circle of Facebook friends, allowing them to swipe between pictures, status updates and other important events.
It also integrates messaging into a new feature called Chat Heads, icons with profile pictures that pop up when receiving text or Facebook messages.
Smartphone maker HTC and wireless carrier AT&T also appeared to unveil the HTC First, a smartphone with Facebook Home pre-loaded and optimized for users.
The phone launches April 12 for $99.99.
Facebook Home will also be available April 12 on Android devices such as the HTC One, the Samsung Galaxy Note II and the Galaxy SIII and S4.
