Google and Facebook share the interface
The new interface runs on top of Facebook Home's Cover Feed, a rich, graphic-revolving stream from the user's Facebook News Feed. On top of Coverfeed are open conversations designated by Chat Heads, a feature that shows a circular image of the Facebook friends who have recently sent messages. Also displayed are notifications for new emails, Facebook messages and activity, Google Now updates, and upcoming Google Calendar events. Those concerned about privacy can turn off Cover Feed.
