Moving in the touch UI is done by touch down and move (dragging); touch down + move + touch release with speed (flick); or with a scrollbar.
In dragging interaction, the content follows the finger movements. In flicking interaction, the content continues its movement according to the parameters detected before the touch release. The movement of content slows down with inertia.
When moving the content, the boundaries are indicated with empty area appearing after the actual content. There can be as much empty area visible as user can drag the display. Touch release hides the empty area immediately.
