The BlackBerry 10 homescreen shows four panes which are active apps — tapping on a pane takes you to the app proper.

We’ve seen the live action of BB10 ‘Flow‘ UI earlier at BlackBerry World 2012 while RIM CEO Thorsten Heins & RIM Software Product team Manager Vivek Bharadwaj demoed the revolutionary BlackBerry on stage. Today we got some more in-depth details of the next gen gesture based RIM operating system. We all are aware of button-less BlackBerry PlayBook gestures & realtime multitasking goodness which is now being expanded on BB10 platform! The first image above shows a 4 minimized running apps panel giving a live view(not recently opened) of each app simultaneously. Clicking on one will maximize into app as similar to PlayBook experience.

Swiping left from the homescreen takes you to this traditional grid-of-apps view (pictured above), while swiping right from the homescreen takes you into a unified inbox.

The app menu/panel has a complete new UI as well & are also Live that means the pictures icon changes showing your last snapped photo, clock app showing your alarm setup etc. The menu has an action bar below giving quick access to camera, universal search & call. This screen is accessed by swiping left from homescreen (4 app panel)

At any point in the OS you can ‘glance’ at notifications or your inbox by holding a thumb at the corner of the screen and pulling these panes across.

The left slide shows how the swipe interface displays the inbox, an email and an attachment on screen at once. The other slide shows some of the accounts that can be synced.
