Hold and Move enables manipulation and navigation in parallel on touch devices. The first touch events are associated with the background and applied for navigation (e.g. scrolling and zooming). Thereby, they provide a reference frame for the successive manipulation of foreground items (e.g. drag and drop). Based on the detection of this temporal sequence, Hold and Move can easily be distinguished from simultaneous multi-touch input like the pinch-zoom gesture.
