Abstract:
Moving a pointer in a graphical user interface environment is provided. An input comprising an initial delta value determined by a device driver is received from the device driver. The initial delta value is located in a data structure. A new delta value associated with the initial delta value is selected from the data structure. A new position of a pointer in the graphical user interface environment is calculated based on the new delta value. The new position of the pointer is sent to the graphical user interface environment for rendering.
