In order to overcome the inconvenience of traditionally creating, closing and switching operations on the interface by clicking a specific button, the present invention directly creates, closes and switches the interface of the mobile terminal through the user's drag gesture, so that the operation of the mobile device interface is more Free and intuitive. Based on the application control of such a gesture, the mobile terminal to which the method of the present invention is applied is a mobile terminal or other device having a touch screen.

1 shows a flow chart of a method of controlling an application interface by a drag gesture in accordance with the present invention. As shown in FIG. 1 , when the user needs to perform a new creation, a shutdown, or a switching operation on the application interface of the mobile terminal, the touch screen of the mobile terminal only needs to input the corresponding touch information by using a touch screen of the mobile terminal, and the touch screen of the mobile terminal senses the user's touch acquisition. a drag gesture input by the user (step S110); then identifying the drag gesture input by the user (step S120), and then searching for a match in the mobile terminal database corresponding to the drag gesture (step S130), and then ringing The corresponding interface operation should be performed to display the application interface control result corresponding to the drag gesture input by the user to the user (step S140).

Since the single-finger operation has been given many functions with high frequency of use in the operation of the current touch screen terminal, in order to make the control of the application interface easier and faster, in the present invention, double fingers or single fingers and doubles are preferred. Refers to the way you type the drag gesture. Wherein, the operation of the two-finger input can be given to the control between the application interfaces, and the operation of the single-finger input is given to the control in the same interface. In this control mode, the single-finger input and the two-finger input are relative to the controlled application interface. Words are the logical relationship between singular and plural.

For a correspondence between a specific drag gesture and a corresponding application interface control operation, a specific gesture and a list of corresponding interface controls may be pre-stored in the mobile terminal database as a default matching relationship, and the user may also be within a given gesture range. Choose to add a new setting or change a specific gesture that controls the app interface. In addition, in order to enhance the human-computer interaction of the user to control the operation of the application interface, the interaction animation of the application interface response control operation may be drawn in the form of an interactive animation in response to an operation corresponding to the drag gesture of the user input. The application interface control result corresponding to the drag gesture input by the user is displayed to the user, so that the user has a more intuitive and visual sensory experience on the application interface control operation. The interactive animation form corresponding to the control application interface can be flexibly set according to the user's preference.

The following is an exemplary illustration of the manner in which the drag gestures of the two-finger input, the single-finger, and the two-finger input are controlled to control the application interface. Single-finger and two-finger input and drag gestures control the application interface, such as: two-finger touch interface, call out multiple interface thumbnails; single-finger click, drag and drop to complete an interface close, insert, switch and other operations.
