Abstract:
1. An electronic device comprising: a user input device comprising: a touch sensitive surface arranged in and forming a part of a surface of the electronic device and being arranged to provide a desired number of pre-defined touch sensitive surface areas each of said touch sensitive surface areas being associated with a respective corresponding pre-defined functionality; appropriate control circuitry responsive to a touching contact with a said touch sensitive surface area configured to control the velocity and direction of movement of a cursor in a display graphic shown on a screen carried by the electronic device wherein: a first pre-defined touch sensitive surface area comprises a first pre-defined functionality configured to cause the cursor to move in a corresponding first direction in response to a sliding motion touching contact with said first pre-defined touch sensitive surface area in a first direction on said first pre-defined touch sensitive surface area to accelerate the cursor movement in said corresponding first direction and in a second direction opposite said first direction on said first pre-defined touch sensitive surface area to decelerate the cursor movement in said corresponding first direction; a second pre-defined touch sensitive surface area comprises a second pre-defined functionality configured to cause the cursor to move in a corresponding second direction in response to a sliding motion touching contact with said second pre-defined touch sensitive surface area in a first direction on said second pre-defined touch sensitive surface area to accelerate the cursor movement in said corresponding second direction and in a second direction on said second pre-defined touch sensitive surface area for decelerating the cursor movement in said corresponding second direction; and a third pre-defined touch sensitive surface area comprises a third pre-defined functionality configured to cause the cursor to stop movement in response to a touching contact with said third pre-defined touch sensitive surface area.
