In step 304, the first time duration Tl of the first land of the object on the touch device is compared with a first reference time, if Tl is smaller than tn, it is jumped to step 300, otherwise to step 305. The first time duration Tl of the first land of the object is compared with a second reference time, if Tl is larger than t12, it is followed to step 308 for further determination of the action, if Tl is no more than t12, it is followed to step 307 to detected a second land of the object in the fourth reference time t22. Meanwhile if the counter reaches the third reference time t21, a first middle signal 21 is generated. In step 307, if no second land of the object is detected in the fourth reference time t22 after the first leave of the object from the touch device, it follows to step 309, the first middle signal 21 is terminated at t22 and a single click signal 204 is generated.
Referring Figs. 4 and 5, if the second land of the object is detected in the fourth reference time t22 after the first leave of the object from the touch device, that is a second time span T2 between the first land and the second land of the object on the touch device is no more than the fourth reference time, it is followed to step 310, a second time span T2 between the first land and the second land of the object on the touch device is compared with a third reference time t21. If T2 is smaller than t21, it is followed to step 308, otherwise to step 312 to detect a second leave of the object, and the first middle signal is terminated when a second leave of the object is detected. In step 313, a second time duration T3 is compared with a fifth reference time t3i, if T3 is less than t31, it is jumped to step 308, if T3 is no less than t31, step 314 is followed where the second time duration T3 is compared with a sixth reference time t32 from the second land of the object on the touch device, if T3 is no more than t32, step 315 is followed where the first middle signal 21 is terminated when the second leave of the object from the touch device and a second middle signal 22 and a double signal 205 are generated, otherwise to step 316 as shown in Fig. 4 and Fig. 7, and then the first signal 21 is terminated when the second leave of the object from the touch device is detected, resulting a drag signal 206 .
According to an embodiment of the invention, as shown in Fig. 4B, the steps before step 310 are similar to the method as mentioned in Fig. 4A. Therefore, the detailed description thereof is hereby omitted for clarity purpose. In the following, only the differences between Fig. 4A and Fig. 4B will be described.
As shown in Fig. 4B, if the second time span T2 is greater than or equal to the third reference t21 and less than or equal to the fourth reference t22, the method detects a second leave of the object at step 3121. The counter counts until the second leave of the object is detected. If the second leave of the object on the touch device is detected in the sixth reference time t32, a second time duration T3 is recorded, the method may compare a second time duration T3 to a fifth reference t31 at step 313. If the second time duration T3 compared at step 313 is less than the fifth reference t31, the method goes the step 308. If the second time duration T3 is greater than or equal to the fifth reference t31, that is, the second time duration T3 is greater than or equal to the fifth reference t31 and less than or equal to the sixth reference t32, the first middle signal is terminated, and a second middle signal is generated. A double-click signal is then output at step 315. If a second leave of the object is not detected in the sixth reference time t32, a drag signal is output at step 316. Then a second leave of the object is detected at step 318. And when the second leave of the object from the touch screen is detected, the drag signal is terminated at step 320.
In the following, an action identifying device for a touch device may be described in detail with reference to Figs. 5 and 8.
According to an embodiment of the present disclosure, an action identifying device for a touch device may be provided, which is shown in Fig. 8 where the action identifying device is schematically shown comprising a detecting unit 110, a counter 130 and a processing unit 120 connected with the detecting unit 110 and the counter 130 respectively. The detecting unit 110 is configured to detect a land or a leave of an object on the touch device, the counter is configured to measure the time; and the processing unit is configure to record the time of the counter, compare the recorded time with a reference time and output a single click signal, a double click signal or a drag click signal.
As shown in Figs. 5 and 8, when the touch device starts working, the counter 130 starts to time from zero to maximum and maintain the maximum value if no land of an object is detected on the touch device. The detecting unit 110 detects a first land of the object on the touch device. TO is a first time span between the time the counter 130 is reset and restarted and a time of the first land of the object on the touch device. The first time span TO is recorded by the processing unit 120. If the first time span TO is no less than the first reference time tnand no more than the second reference time ti2j the first middle signal 21 is generated at the third reference time t2i . If no second land of the object on the touch device is detected in the fourth reference time t22, the first middle signal 21 is terminated, and a single click signal is generated accordingly.
As shown in Figs 6 and 8, if a second land of the object on the touch device is detected by the detecting unit 110 in the fourth reference time t22, and the second time span T2 between the first land and the second land of the object is larger than a third reference time t21 and smaller than the fourth reference time t22j the first middle signal 21 is maintained, and the leave of the object from the touch device is detected by the detecting unit 110. T3 is a second time duration from the second land of the object on the touch device. If T3 is larger than the fifth reference time t3i and no more than the sixth reference time t32, then the first signal 21 is terminated when a second land of the object leaves the touch device, a second signal 22 is generated and a double click signal 205 is generated by the processing unit 130.
As shown in Figs. 7 and 8, if T3 is larger than the sixth reference time t32, the first middle signal 21 is maintained, and the first signal 21 is terminated after the second leave of the object from the touch device, and a drag signal 206 is generated by the processing unit 130 accordingly.
In some embodiments, referring to FIG. 7, if a second leave of the object is not detected in the sixth reference time t32, a drag signal is output after the counter reaches the sixth reference time t32. And then when the second leave of the object is detected, the drag signal is terminated.
As described above, due to the first time duration, second time span and second time duration compared with more than one reference time respectively, in other words, the first time duration, second time span and second time duration are compared with a period of time rather than a fixed value, so that an error operation or erroneous determination of the action may be avoided.
While the present disclosure has been described in conjunction with the embodiment thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. Accordingly, it is intended to embrace all such alternatives, modifications and variations that fall within the spirit and scope thereof as set fourth in the appended claims.
