Abstract: A method and system for handling frame dropping during playback of a PPT file. The method comprises operating the DXGI screen capturing module to acquire a prepositioned frame in a graphics card cache (S100); acquiring screen data according to the prepositioned frame (S200); monitoring the screen data and timing a duration in which the screen data does not change (S300); and modifying the screen data when the duration exceeds a preset threshold (S400); performing screen capture by the DXGI screen capturing module when the screen data changes (S500). During the whole process, when the duration in which the screen data does not change exceeds the preset threshold, the screen data is actively modified, so that the frame dropping that occurs when there is no change in the screen data may be avoided, thereby enabling effective handling of the frame dropping during playback of the PPT file.

Abstract: Disclosed are a method and a system for detecting a touch pattern width and identifying the touch pattern, including receiving, from a touch device, first coordinate information and corresponding touch width information for a touch pattern, and storing the first coordinate information and the touch width information, receiving, from an operating system, second coordinate information for a current touch pattern, and searching, from the stored first coordinate information, for one consistent with the second coordinate information, and determining the touch width information corresponding to the first coordinate information that has been found as width information of the current touch pattern.

Abstract: A touch operation method based on an interactive electronic white board and a system thereof, by detecting touch operation data such as pressure sensitive data, touch width data and touch coordinate data, then identifying, based on the touch operation data, a corresponding control instruction according to a preset algorithm, and sending the control instruction to the interactive electronic whiteboard, allows a user to realize a corresponding operation by directly touching the interactive electronic whiteboard without clicking on the respective functional button, thereby improving the operation convenience and enhancing the user experience.

Abstract: The present invention provides an all-in-one machine, a method for the all-in-one machine to realize quick touch in all channels, and a computer storage medium. The method includes: detecting which channel is currently connected to the main board, and controlling a USB selecting switch to connect a first data port of a touch frame with a USB port of a device or module to which the currently connected channel belongs, based on the detected channel information; determining whether there is an action to call a touch menu when detecting that the channel connected to the main board is an internal PC module channel or an external device channel; and if so, activating the main board to start a touch menu application program, and making response, by the main board, to touch data within an area of the touch menu transmitted from the touch frame through the second data port, after the touch menu has been called and before an action of leaving the touch menu is detected.

Abstract: A method, device and computer storage medium for multichannel touch control of an all-in-one machine are disclosed. The method for multichannel touch control of the all-in-one machine includes: providing a channel display window on a user interface, and setting up link buttons between the channel display window and each channel; setting up a multichannel touch control component on the user interface, receiving touch point information from a user, converting the touch point information into corresponding multichannel operation information, and performing corresponding operation on each channel based on the multichannel operation information. The contents of the multiple channels can be displayed by providing a channel display window on the user interface of the all-in-one machine; with the multichannel touch control component set up on the user interface, the touch control operation on the multiple channels at the same time can be activated.
