Focus On Content - Blackberry PlayBook Ui Manuallines

UI Guidelines Design principles
As part of your canvas strategy, you should consider how the content behaves in response to gestures. One way to do this is
to categorize your canvas as either continuous or discrete. A continuous canvas contains content that can be arbitrarily
subdivided (for example, a map or a building blueprint). A discrete canvas contains content that has obvious, defined
subcomponents (for example, a deck of cards, a contact list, or an eBook).
On a continuous canvas, consider allowing users to move (pan) slowly through the content, move quickly, zoom in and out,
and perhaps rotate. On a discrete canvas, you should also consider allowing users to move (shift) slowly or quickly through
the content, but there are likely some other actions that you might want to enable using gestures. For example, you can flip
over a card, navigate within a contact list, or jump to the next chapter in a document.

Focus on content

Create and present content that absorbs and engages users in a way that is similar to how movie-goers get drawn into the
cinematic experience of a film. Manage the content with seamless workflow transitions.
