MULTI-LAYER USER INTERFACE WITH FLEXIBLE PARALLEL MOVEMENT

摘要

A user interface (UI) system calculates movements in a multi-layer graphical user interface. The UI system receives user input corresponding to gestures on a touchscreen. The UI system calculates a movement of a first layer in a first direction (e.g., a horizontal direction) at a first movement rate. For example, the first movement rate can be substantially equal to the movement rate of a gesture made by a user's finger or other object on the touchscreen. The UI system calculates movements of other layers substantially parallel to the movement of the first layer, at movement rates that differ from the first movement rate.
