Slide the side to unlock
Starting at the beginning, Samsung reimagines the slide-to-unlock gesture as a side-mounted experience.
A place for your bookmarks
One of Samsung's proposed usage scenarios is to push chapter markers and bookmarks off the main screen when reading ebooks.
See the attachment on the side of your phone
Samsung envisions using the extra real estate on the side to provide information about email attachments.
A cute and highly visual way to check if your phone's fully charged: the side-screen would display a bar representation of the handset's charged state. This would be a good match with Samsung's AMOLED displays, which only turn on the pixels that need to display something, making it a power-efficient solution.
Contacts up front, alphabet on the side
As with the majority of other applications, Samsung's contact book concept pushes the organizational aspects of the UI literally off to the side, cleaning up the main display.
The Galaxy Note 3 brought a major overhaul to Samsung's software for clipping and sharing content from the web, and that emphasis is apparent in the new patent application. It details a visual clipboard that lets you stash one or more images on the side panel and then reuse them in things like chat apps.
Scrollable image index
While the main screen displays a conventional gallery overview, its sidecar can serve as a category sorter — scrolling through such things as event dates.
Multitouch quick actions
If unlocking your phone with a slide is too conventional, Samsung will also let you do it by placing two fingers on particular areas of the side screen. Additionally, once inside the UI, there'll be other quick actions available to speed up the user experience. Interestingly, the drawings here show the Android buttons rendered in software rather than in capacitive or physical keys — which is something Samsung hasn't yet done with it flagship phones.
