The present disclosure relates to a method and a system for remote collaboration, the method includes: receiving mouse operation information of a user in the master computer which is captured and transmitted by the master computer; detecting a position of the mouse cursor on the master split screen in accordance with the mouse operation information, then when the cursor arrives at a boundary of the master split screen and continues to move in a direction away from the master split screen, detecting a current split screen connecting to the boundary, and displaying the cursor on the current split screen; and receiving interaction information transmitted by the master computer, and transferring the interaction information to a current slave computer corresponding to the current split screen, so as to cause the current slave computer to execute the interaction information, where the interaction information is the information which is obtained and intercepted by the master computer when the master computer detects interaction initiated by the user with the master computer. The present disclosure can realize the collaboration function in wireless screen transmission based on the display of multiple sources on the same screen, thus rendering the operations convenient.

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.

A system and method for is disclosed for controlling coordination between medical devices, a medical workstation and a communication device. The system comprises: message transceiving units arranged corresponding to a plurality of medical detection display apparatuses respectively for forwarding, to a coordination message processing unit, interaction information acquired from an accessed external input device by the medical detection display apparatuses arranged corresponding to the message transceiving units themselves. The coordination message processing unit receives the interaction information from a message transceiving unit connected thereto, parses the interaction information to obtain an identifier corresponding to a medical detection display apparatus designated by a user, and converts the interaction information into a display message matching the designated medical detection display apparatus according to a display requirement corresponding to the identifier. By means of the present disclosure, the problem of the inconvenience in multi-screen operation control in the existing medical workstation is solved.

An electronic device includes a touch-sensitive display screen to display a graphical representation of a mathematical relationship and to enable a user to enter a one-dimensional touch gesture thereon for performing a one-dimensional adjustment function for the displayed graphical representation. A display adjustment module interprets the one-dimensional touch gesture and performs the one-dimensional adjustment function. The display adjustment module performs a one-dimensional zoom adjustment function in response to one of a one-dimensional pinch touch gesture and a one-dimensional spread touch gesture. The one-dimensional zoom adjustment function increases or reduces a displayed range of values in a first dimension while maintaining unchanged a displayed range of values in a second dimension of the displayed graphical representation.
