Abstract

A non-straight gesture recognition method is used for a touch device which includes a touch display panel and a data processing module. The method comprises: a user draws on the touch display panel to form a non-straight line locus; next, the data processing module registers a movement time from the non-straight line locus and captures a plurality of locus points to establish a locus equation to calculate a first-order differential value and a quadratic differential value; finally the data processing module judges a locus configuration of the non-straight line locus based on the movement time, first-order differential value and quadratic differential value and orders the multi-touch device to execute a preset program corresponding to the locus configuration. The non-straight line locus can be formed in various types of locus configurations to activate different types of corresponding preset programs, and also reduce user'"'"'s erroneous operation.

Claims

1. A non-straight gesture recognition method for a touch device which includes a touch display panel and a data processing module electrically connected to the touch display panel, the method comprising the steps of:

Step S1;

touching the touch display panel by a user and drawing on the touch display panel to form a non-straight line locus;

Step S2;

detecting the non-straight line locus by the data processing module and registering a movement time from the non-straight line locus, and capturing a plurality of locus points to establish a locus equation to calculate a first-order differential value and a quadratic differential value; and

Step S3;

judging by the data processing module a locus configuration of the non-straight line locus based on the movement time, the first-order differential value and the quadratic differential value and ordering the touch device to execute a preset program corresponding to the locus configuration.

2. The method of claim 1, wherein at Step 2 the data processing module gets a start point and an end point from the locus points according to the movement time.

3. The method of claim 2, wherein at Step 3 the locus equation contains the first-order differential value and the quadratic differential value that gradually decrease from the start point to the end point, the data processing module judging the locus configuration being a first curve and ordering the touch device to execute a first preset program corresponding to the first curve.

4. The method of claim 2, wherein at Step 3 the locus equation contains the first-order differential value which gradually increases from the start point to the end point and the quadratic differential value which gradually decreases from the start point to the end point, the data processing module judging the locus configuration being a second curve and ordering the touch device to execute a second preset program corresponding to the second curve.

5. The method of claim 2, wherein at Step 3 the locus equation contains the first-order differential value and the quadratic differential value that gradually increase from the start point to the end point, the data processing module judging the locus configuration being a third curve and ordering the touch device to execute a third preset program corresponding to the third curve.

6. The method of claim 2, wherein at Step 3 the locus equation contains the first-order differential value which gradually decreases from the start point to the end point and the quadratic differential value which gradually increases from the start point to the end point, the data processing module judging the locus configuration being a fourth curve and ordering the touch device to execute a fourth preset program corresponding to the fourth curve.

7. The method of claim 1, wherein at Step 2 the movement time ranges from 0.3 second to 0.6 second.

8. The method of claim 1, wherein at Step 1 the non-straight line locus is not continuous.

9. The method of claim 1, wherein at Step 3 the locus configuration is selected from the group consisting of a curve contained concave upward, a curve contained concave downward, a curve contained an inflection point and combinations thereof.

10. The method of claim 1, wherein the step S1 is preceded by a settled step in which the user draws on the touch display panel to form a settled line pattern to establish the corresponding locus configuration and a preset program corresponding to the locus configuration that requires activation.
