Method and controller for identifying double tap gestures
First Claim
8. A controller of the touch device, with which it is used to identify gesture of an object on the touch device, the controller comprising:
- an operational unit, being used to detect every appearance of the object on the touch device and accordingly producing a respective tap signal, the respective tap signal being generated corresponding to the start of the appearance on the touch device and being terminated when that appearance finishes; and
a gesture unit, being connected to the operational unit so as to receive the tap signal, calculating the time duration of the object appearing on the touch device based on the tap signal and identifying movement of the object;
wherein, the gesture unit receives from the operating unit the generated first tap signal and the second tap signal corresponding to the first and second appearance of the object on the touch device respective;
the gesture unit also computes the summation of the first appearing time duration, the second appearing time duration and then time span between the two appearing time durations and compares this result with the first reference time; and
if the sum is smaller than the first reference time value, then produce the first signal that presents the first and second appearance.

Abstract
A method of identifying double tap gesture, wherein the double tap gesture is produced on a touch device and characterize in that: when the summation of the first appearing time duration, the time span between the two appearing time durations and the second appearing time duration is smaller than the first reference time, then generate a first signal that represents the first and second appearances. This is to simulate the double tap signal output from the double clicking of the mouse button and so as to achieve a short, simple and reliable determination.

16. A gesture unit of the touch device, which is used to identify movement of an object on the touch device, wherein the gesture unit receives from the operating unit the generated first tap signal and the second tap signal corresponding to the first and second appearance of the object on the touch device respective, the gesture unit also computes the summation of the first appearing time duration, the second appearing time duration and then time span between the two appearing time durations and compares this result with the first reference time;
and if the sum is smaller than the first reference time value, the first signal that presents the first and second appearance is produced. - View Dependent Claims (1, 2, 3, 4, 5, 6, 7, 17, 18, 19, 20)
