Enable the smart terminal, open the song play interface of the smart terminal, open the song audition function, and play the song. Define the currently playing song as the first song. The user issues a gesture operation to the playback interface. Gesture operation In the actual application process, the user does not need to click with the finger, just swipe on the screen and execute a specific gesture, and then the application can be activated to complete, convert and close the execution command. Different gestures can execute different control commands by calling different functions. Common gesture operations include a tap gesture, a double tap gesture, a tap gesture, a press gesture, a flash gesture, a zoom gesture, and a turn gesture. Among them, a tap gesture refers to quickly touching the screen to launch an application or activate an image. A double tap gesture refers to tapping the screen twice in quick succession to open or close an application or document. Tap the swipe gesture to place your finger on the screen and swipe to move items on the display or zoom in and out, maps, and pictures. Pressing a gesture means placing a finger on the screen for a period of time to open the document, launching an application or other function. A flashing gesture refers to quickly moving a finger in the up and down direction on the screen to scroll or slide a series of items or pages. A zoom gesture refers to placing two fingers on the screen and moving them closer or apart to enlarge or reduce the display item. A turning gesture refers to placing two fingers on the screen to rotate in a clockwise or counterclockwise direction to rotate an object displayed on the screen. The gesture operation in this embodiment is a one-hand gesture operation with a sliding direction, and belongs to a sliding gesture, which is also a common operation. In the prior art, the swipe gesture is mainly used to view a page that cannot be completely displayed on the screen, and functions like a scroll wheel of a mouse. This operation is mainly used to view images, web pages, plain text (sms, mail, notes). Swipe from left to right or right to left to switch between the previous and next articles. Swipe from left to right or right to left at the edge of the screen to switch between the previous tab and the next tab. The different sliding directions based on the sliding gesture include sliding to the left, sliding to the right, sliding upward, sliding downward, sliding to the left, sliding to the left, sliding to the right, and sliding to the right. This embodiment gives a new function of the sliding gesture. That is, the smart terminal executes corresponding control commands according to different sliding directions. And the execution object of the gesture operation in the embodiment (ie, the display item in the screen) is the first song currently being played by the song playing interface.

Obtaining a corresponding control instruction according to the sliding direction;

The smart terminal parses the sliding direction of the gesture operation according to the gesture operation received by the screen, and finds a control instruction matching the gesture operation with the sliding direction through the gesture database built in the smart terminal, and executes according to the control instruction. In this way, the user can touch the application in the smart terminal through the gesture operation to complete the execution command such as opening, converting and closing.

When the currently played first song is a song that the user likes, the user sends a gesture operation in the first direction to the screen of the smart terminal, and the gesture operation in the first direction performs a control instruction on the song playing interface.
