An electronic device includes a touch panel interface that receives information from a touch panel indicating sensed movement between two user touch positions on the touch panel, and identifies that at least two time-overlapping touches have occurred at different positions on the touch panel in response to at least a threshold speed of the movement. The touch panel interface identifies that at least two time- overlapping touches have occurred on the touch panel in response to a speed of movement from one touch coordinate position to another exceeding the threshold speed. The touch panel interface also identifies that a single touch has occurred with subsequent sliding while pressed against the touch panel from one touch coordinate position to another in response to the movement having less than the threshold speed. Because the touch panel controller can distinguish between a single touch and at least two time-overlapping touches, it can enable a user to use various combinations of such touches to trigger different operational modes of the electronic device. |
