20140331190 | NON-STRAIGHT GESTURE RECOGNITION METHOD FOR TOUCH DEVICES - 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. | 11-06-2014 |
