User interaction via a touch screen

摘要

A system for user interaction via a touch screen comprises a first touch unit (1) for detecting a first touch event associated with a first interactive area of a touch screen, wherein the first interactive area is associated with an operation type. A data display unit (3) is arranged for displaying at least part of a dataset in a second interactive area of the touch screen. A second touch unit (2) is arranged for detecting a touch move event associated with the second interactive area. An associating unit (4) is arranged for associating the operation type with the touch move event if the touch move event was detected while a touch of the first interactive area associated with the first touch event is still ongoing. An operation unit (5) is arranged for determining an operation based on the operation type and the touch move event.
