  • Publication number: 20200134504
    Abstract: A system of training behavior labeling model is provided. Specifically, a processing unit inputs each data of a training data set into a plurality of learning modules to establish a plurality of labeling models. The processing unit obtains a plurality of second labeling information corresponding to each data of a verification data set and generates a behavior labeling result according to the second labeling information corresponding to each data of the verification data set. The processing unit obtains a labeling change value according to the behavior labeling result and first labeling information corresponding to each data of the verification data set. The processing unit, if determining that the labeling change value is greater than a change threshold, updates the first labeling information according to the behavior labeling results, exchanges the training data set and the verification data set and reestablishes the labeling models.

  • Publication number: 20150153925
    Abstract: A method for operating gestures and a method for calling a cursor adapted to an electronic device having a touch area are provided. The method for calling the cursor is as follows. A first gesture input to the touch area by an operating object is received. It is detected whether a second gesture is continuously input by the operating object from an end point of the first gesture after the first gesture is input. When the second gesture is not continuously input by the operating object from the end point and the operating object leaves the touch area, a first operation is executed. When the second gesture is continuously input by the operating object and the operating object does not leave the touch area, a cursor is called and the cursor is moved to a location where the operating object contacts the touch area.
