Users can perform human-computer interaction through the keyboard and mouse connected to the console output node. For example, by controlling the keyboard and mouse, they can log in to the UI interface on the monitor where the console signal is output, and the local signal source screen is displayed on the monitor.

[0041] Embodiment 1

[0042] Figure 1 FIG. is a flowchart of a method for determining a coordinate control mode of an output node applied to input device connection according to Embodiment 1 of this application. The embodiments of this application are applicable to the situation of determining the coordinate control mode of an input device. This method can be executed by a device for determining a coordinate control mode, which can be implemented in the form of hardware and / or software. The device for determining a coordinate control mode can be configured in an electronic device, and the electronic device can be an output node connected to an input device.

[0043] As Figure 1 shown, the method includes:

[0044] S110. Determine the absolute coordinates when the display icon corresponding to the input device is displayed at a preset position, and send the absolute coordinates to an information processing end, and the information processing end converts the absolute coordinates into logical coordinates in the absolute coordinate mode.

[0045] Figure 2 FIG. is a schematic diagram of the networking of the KVM system provided by the embodiment of this application. As Figure 2 shown, the output node can obtain the event messages generated when the keyboard and / or mouse perform user operations through a USB bus controller, and send the messages to the application layer. The application layer sends the event messages to the corresponding input node or output node through the network according to the KVM system networking and the control modes of the keyboard and mouse. If the output node (such as the output node connected to the video wall) receives the event message, it sends the event message to the virtual keyboard and mouse node of the UI for UI rendering and displays it on the video wall. If the input node receives the event message, it sends the USB signal to the computer connected to the input node through the hardware chip interface for operations such as file processing. The input device in the embodiments of this application can be Figure 2The keyboard and / or mouse in it. The information processing end is Figure 2 The front end in it, such as the input node and the computer mainframe. The display icon can be an icon representing the input device and acting according to the instructions of the input device, and the specific form is not limited. For example, it is an arrow corresponding to the mouse. The preset position can be determined according to the actual situation. For example, it can be the midpoint position of the display interface. The absolute coordinates of the preset position are known, and the absolute coordinates are determined according to the preset position and the display resolution. For example, for a display interface with a display resolution of 1920*1080, when the preset position is the midpoint position, the absolute coordinates of the display icon are (959, 539). When the preset position is one-third of the horizontal direction and the midpoint position of the vertical direction, the absolute coordinates of the display icon are (639, 539). The display interface here refers to the display interface of the first display screen.

[0046] Exemplarily, in order to determine whether the current display screen supports cross-screen display through the display effect of the display icon corresponding to the input device, the display icon corresponding to the input device can be made to be displayed at the preset position of the display interface, and the absolute coordinates when the display icon is displayed at the preset position can be determined, so as to determine the position where the display icon should be displayed on the display interface theoretically if it can support cross-screen display. The output node sends the absolute coordinates to the information processing end. Assuming that the display screen supports cross-screen display, the information processing end converts the absolute coordinates into logical coordinates according to the absolute coordinate mode applicable to cross-screen display. Specifically, the information processing end can include a virtual keyboard and mouse node for performing keyboard and mouse simulation. The virtual keyboard and mouse node determines the maximum logical coordinates of the keyboard and mouse movement according to the report descriptor, and determines the logical coordinates corresponding to the absolute coordinates according to the absolute coordinates, the display resolution and the maximum logical coordinates. The maximum logical coordinates are the maximum coordinates that the display icon corresponding to the input device can reach on the display interface it supports. As Figure 3 shown, if there are two horizontally spliced display screens and the two display screens support cross-screen display, the display icon of the mouse can be displayed on the two display screens, and the maximum coordinates that the display icon can reach are the lower right corner of display screen B, and the logical coordinates of this point are the maximum logical coordinates. If the maximum logical coordinates of the input device are (32767, 32767), then the logical coordinates of this point are (32767, 32767). The lower right corner of display screen A is located at the midpoint of the lower edge, and the logical coordinates are (16383, 32767). According to the absolute coordinates and the display resolution, the position of the display icon on the display interface can be determined, and then according to the position and the maximum logical coordinates, the logical coordinates of the display icon can be determined. As Figure 3As shown, if the absolute coordinates of the mouse are (959, 539) and the display resolution is 1920*1080, it can be determined that the display icon of the mouse should be located at the midpoint of display screen A. According to this position and the maximum logical coordinates, the logical coordinates of the display icon are calculated as (8191, 16383), where 8191 is obtained by (16384 / 2)-1 and 16383 is obtained by (32768 / 2)-1. The virtual keyboard and mouse node sends the logical coordinates to the terminal, such as Figure 2 the computer host in. The instruction sent can be "echo–n–e “\x00\xff\x1f\xff\x3f\x00”> / dev / hidg0", where \xff\x1f represents the abscissa 8191 of the logical coordinates, and \xff\x3f represents the ordinate 16383 of the logical coordinates. dev / hidg0 represents the character device simulated by the virtual keyboard and mouse node for the mouse.

[0047] S120. Receive the actual coordinates sent by the display device corresponding to the information processing end; where the actual coordinates are the actual coordinates of the display icon when the display image determined by the information processing end according to the logical coordinates is displayed on the corresponding display device.

[0048] Exemplarily, after the information processing end converts the absolute coordinates into logical coordinates, it generates a display image according to the logical coordinates of the display icon, and sends the display image to the display device for display. Specifically, the computer host of the information processing end converts the logical coordinates into coordinates on the display interface, generates a display image including the display icon, and sends the display image to the display device for display. The display device receives the display image for decoding and display, captures the display graphics of the displayed display interface using a programming language and a graphics library, and determines the actual coordinates of the display graphics. The display device sends the actual coordinates of the display graphics to the output node, and the output node receives the actual coordinates sent by the display device.

[0049] S130. Determine the coordinate control mode of the input device according to the absolute coordinates and the actual coordinates.

[0050] Exemplarily, if at least two display screens support cross-screen display, the actual coordinates of the display icon captured by the display device should be the preset position of the first display screen. If cross-screen display is not supported, the actual coordinates of the display icon captured by the display device are not located at the preset position of the first display screen. The absolute coordinates of the display icon are the coordinates of the preset position. According to the absolute coordinates and the actual coordinates, it can be determined whether the display icon is displayed at the preset position of the display screen, and whether the display screen supports cross-screen display, so as to determine the coordinate control mode matching the actual display mode of the display screen.

[0051] The technical solution of the embodiment of the present application is executed by an output node connected to an input device. The method includes: determining the absolute coordinates when a display icon corresponding to the input device is displayed at a preset position, and sending the absolute coordinates to an information processing end, where the information processing end converts the absolute coordinates into logical coordinates in an absolute coordinate mode; receiving the actual coordinates sent by a display device corresponding to the information processing end; where the actual coordinates are the actual coordinates of the display icon when a display image determined according to the logical coordinates is displayed on the corresponding display device; determining the coordinate control mode of the input device according to the absolute coordinates and the actual coordinates. The above solution can pre-determine whether the display icon corresponding to the input device can be displayed across screens according to the actual coordinates and the theoretically absolute coordinates when the display icon is displayed, so as to determine the coordinate control mode in a timely and accurate manner, and display the display icon of the input device based on the coordinate control mode, avoiding the problem of abnormal display caused by the mismatch between the coordinate control mode and the display method supported by the screen.

[0052] Embodiment 2

[0053] Figure 4 The flowchart of a method for determining a coordinate control mode provided by Embodiment 2 of the present application. The embodiment of the present application is optimized based on the above embodiment. For the solutions not described in detail in the embodiment of the present application, please refer to the above embodiment. As Figure 4 shown, the method of the embodiment of the present application specifically includes the following steps:

[0054] S210. Determine the absolute coordinates when a display icon corresponding to the input device is displayed at a preset position, and send the absolute coordinates to an information processing end, where the information processing end converts the absolute coordinates into logical coordinates in an absolute coordinate mode.

[0055] S220. Receive the actual coordinates sent by a display device corresponding to the information processing end; where the actual coordinates are the actual coordinates of the display icon when a display image determined according to the logical coordinates is displayed on the corresponding display device.

[0056] S230. If the distance between the absolute coordinates and the actual coordinates is less than a preset distance, determine that the coordinate control mode of the input device is the absolute coordinate mode.

[0057] Exemplarily, the information processing terminal calculates the logical coordinates in the absolute coordinate mode based on the absolute coordinates on the assumption that the display screen supports cross-screen display, and then generates a display image according to the logical coordinates. If the display screen supports cross-screen display, the position corresponding to the actual coordinates of the displayed icon in the display image should be the preset position corresponding to the absolute coordinates. There may also be errors resulting in a deviation in the position, but the position deviation should not be too large. Therefore, a preset distance can be set in advance to reflect the position deviation caused by the allowable error. If the distance between the absolute coordinates and the actual coordinates is less than the preset distance, it indicates that the display screen supports cross-screen display. At this time, the coordinate control mode of the input device is determined to be the absolute coordinate mode. For example, as Figure 3 shown, if display screen A and display screen B support cross-screen display, the display resolution is 1920*1080, the preset position is the midpoint of display screen A, the absolute coordinates are (959, 539), and the converted logical coordinates are (8191, 16383), then if the actual coordinates of the displayed icon captured by the display device in the display image are also (959, 539), or the distance from (959, 539) is less than the preset distance and is near the midpoint of display screen A, the coordinate control mode of the input device is determined to be the absolute coordinate mode.

[0058] S240. Otherwise, determine that the coordinate control mode of the input device is the relative coordinate mode.

[0059] Exemplarily, if the distance between the absolute coordinates and the actual coordinates is greater than or equal to the preset distance, it indicates that the position of the displayed icon reflected by the actual coordinates in the display image differs greatly from the position of the displayed icon reflected by the absolute coordinates, and the display screen does not support cross-screen display. Determine that the coordinate control mode is the relative coordinate mode matching the non-support for cross-screen display. For example, as Figure 5 shown, if display screen A and display screen B do not support cross-screen display, the displayed icon of the input device can only be displayed on one display screen, and the logical coordinates of the lower right corner of display screen A are (32767, 32767). At this time, if a displayed icon with absolute coordinates of (959, 539) is to be displayed, as Figure 5 shown, the actual coordinates of the displayed icon are (479, 539), and the distance between the absolute coordinates and the actual coordinates is greater than or equal to the preset distance, indicating that the position of the displayed icon reflected by the actual coordinates in the display image differs greatly from the position of the displayed icon reflected by the absolute coordinates, and the display screen does not support cross-screen display. Determine that the coordinate control mode is the relative coordinate mode matching the non-support for cross-screen display.

[0060] In the embodiments of the present application, if the number and arrangement of display screens are known, the logical coordinates can be calculated based on the absolute coordinates of the display icons, and then the predicted coordinates of the display icons can be calculated theoretically if the display screens do not support cross-screen display. Compare the predicted coordinates with the actual coordinates. If the distance between the predicted coordinates and the actual coordinates is less than a preset distance, it means that the actual display effect of the display icon is the same as the actual display effect when cross-screen display is not supported, indicating that the display screen does not support cross-screen display, and the coordinate control mode is determined to be the relative coordinate mode.

[0061] The embodiments of the present application provide a method for determining a coordinate control mode. If the distance between the absolute coordinates and the actual coordinates is less than a preset distance, the coordinate control mode of the input device is determined to be the absolute coordinate mode; otherwise, the coordinate control mode of the input device is determined to be the relative coordinate mode. By comparing the actual display effect of the display icon with the theoretical display effect, it is determined in advance whether the display screen supports cross-screen display, so as to accurately determine in real time the coordinate control mode that matches the display mode of the display screen, improve the usability and compatibility of the display, and avoid the problem of abnormal coordinate display caused by the mismatch between the display mode of the display screen and the coordinate control mode.

[0062] Embodiment III

[0063] Figure 6 FIG. 10 is a flowchart of a method for determining a coordinate control mode provided in Embodiment III of the present application. The embodiments of the present application are optimized based on the above embodiments. For the solutions not described in detail in the embodiments of the present application, please refer to the above embodiments. As Figure 6 shown, the method of the embodiments of the present application specifically includes the following steps:

[0064] S310. Determine the absolute coordinates when the display icon corresponding to the input device is displayed at a preset position, and send the absolute coordinates to the information processing end, and the information processing end converts the absolute coordinates into logical coordinates in the absolute coordinate mode.

[0065] S320. Receive the actual coordinates sent by the display device corresponding to the information processing end; wherein, the actual coordinates are the actual coordinates of the display icon when the display image determined by the information processing end is displayed on the corresponding display device.

[0066] S330. Determine the arrangement mode of at least two display screens of the display device.

[0067] Exemplarily, the arrangement mode of at least two display screens can be input by the user in advance. For example, it can be that at least two display screens are arranged horizontally, at least two display screens are arranged vertically, or both horizontal and vertical arrangements are included.

[0068] S340. Determine the coordinate control mode of the input device according to the arrangement, the absolute coordinates, and the actual coordinates.

[0069] Exemplarily, according to the arrangement, the comparison method between the absolute coordinates and the actual coordinates can be determined, and then the coordinate control mode of the input device can be determined according to the comparison result.

[0070] In the embodiments of the present application, determining the coordinate control mode of the input device according to the arrangement, the absolute coordinates, and the actual coordinates includes:

[0071] If the arrangement of at least two display screens is a horizontal arrangement, determine the coordinate control mode of the input device according to the abscissa of the absolute coordinates and the abscissa of the actual coordinates;

[0072] If the arrangement of at least two display screens is a vertical arrangement, determine the coordinate control mode of the input device according to the ordinate of the absolute coordinates and the ordinate of the actual coordinates;

[0073] If the arrangement of at least two display screens includes a horizontal arrangement and a vertical arrangement, determine the coordinate control mode of the input device according to the abscissa and ordinate of the absolute coordinates and the abscissa and ordinate of the actual coordinates.

[0074] Exemplarily, if the arrangement of at least two display screens is a horizontal arrangement, it is necessary to determine whether the display screen supports cross-screen in the horizontal direction and it is not necessary to determine whether the display screen is cross-screen in the vertical direction. Therefore, the coordinate control mode of the input device can be determined according to the abscissa of the absolute coordinates and the abscissa of the actual coordinates. Similarly, if the arrangement of at least two display screens is a vertical arrangement, it is necessary to determine whether the display screen supports cross-screen in the vertical direction and it is not necessary to determine whether the display screen is cross-screen in the horizontal direction. Therefore, the coordinate control mode of the input device can be determined according to the ordinate of the absolute coordinates and the ordinate of the actual coordinates. If the arrangement of at least two display screens includes a horizontal arrangement and a vertical arrangement, it is necessary to determine whether the display screen supports cross-screen in both the horizontal and vertical directions, then determine the coordinate control mode of the input device according to the abscissa and ordinate of the absolute coordinates and the abscissa and ordinate of the actual coordinates.

[0075] In the embodiments of the present application, determining the coordinate control mode of the input device according to the abscissa of the absolute coordinates and the abscissa of the actual coordinates includes:

[0076] If the difference between the abscissa of the absolute coordinates and the abscissa of the actual coordinates is less than the first preset difference, determine that the coordinate control mode is the absolute coordinate mode; otherwise, determine that the coordinate control mode is the relative coordinate mode;

[0077] Determine the coordinate control mode of the input device according to the ordinate of the absolute coordinate and the ordinate of the actual coordinate, including:

[0078] If the difference between the ordinate of the absolute coordinate and the ordinate of the actual coordinate is less than the second preset difference, determine that the coordinate control mode is the absolute coordinate mode; otherwise, determine that the coordinate control mode is the relative coordinate mode;

[0079] Determine the coordinate control mode of the input device according to the abscissa and ordinate of the absolute coordinate and the abscissa and ordinate of the actual coordinate, including:

[0080] If the difference between the abscissa of the absolute coordinate and the abscissa of the actual coordinate is less than the first preset difference, and the difference between the ordinate of the absolute coordinate and the ordinate of the actual coordinate is less than the second preset difference, determine that the coordinate control mode is the absolute coordinate mode; otherwise, determine that the coordinate control mode is the relative coordinate mode.

[0081] Wherein, the first preset difference and the second preset difference can be determined according to the actual situation. Exemplarily, if at least two display screens are arranged horizontally and support cross-screen, the horizontal distribution of the display icons reflected by the actual coordinates should be consistent with the horizontal distribution of the display icons reflected by the absolute coordinates. If the difference between the abscissa of the absolute coordinate and the abscissa of the actual coordinate is less than the first preset difference, determine that the coordinate control mode is the absolute coordinate mode; otherwise, determine that the coordinate control mode is the relative coordinate mode. Similarly, if at least two display screens are arranged vertically and support cross-screen, the vertical distribution of the display icons reflected by the actual coordinates should be consistent with the vertical distribution of the display icons reflected by the absolute coordinates. If the difference between the ordinate of the absolute coordinate and the ordinate of the actual coordinate is less than the first preset difference, determine that the coordinate control mode is the absolute coordinate mode; otherwise, determine that the coordinate control mode is the relative coordinate mode. If at least two display screens are arranged both horizontally and vertically and support cross-screen, the horizontal distribution of the display icons reflected by the actual coordinates should be consistent with the horizontal distribution of the display icons reflected by the absolute coordinates, and the vertical distribution of the display icons reflected by the actual coordinates should be consistent with the vertical distribution of the display icons reflected by the absolute coordinates. If the difference between the ordinate of the absolute coordinate and the ordinate of the actual coordinate is less than the first preset difference, and the difference between the ordinate of the absolute coordinate and the ordinate of the actual coordinate is less than the second preset difference, determine that the coordinate control mode is the absolute coordinate mode; otherwise, determine that the coordinate control mode is the relative coordinate mode.

[0082] An embodiment of the present application provides a method for determining a coordinate control mode, which determines the arrangement mode of at least two display screens of the display device; and determines the coordinate control mode of the input device according to the arrangement mode, the absolute coordinates, and the actual coordinates. By the arrangement mode of the display screens, the comparison mode between the absolute coordinates and the actual coordinates is determined specifically, which simplifies the comparison mode, reduces the computing power, and improves the efficiency of determining the coordinate control mode. And it is determined in advance whether the display screen supports cross-screen display, so as to determine in real time and accurately the coordinate control mode matching the display mode of the display screen, so as to improve the usability and compatibility of the display, and avoid the problem of abnormal coordinate display caused by the mismatch between the display mode of the display screen and the coordinate control mode.

This method can be executed by a device for determining a coordinate control mode, and the device for determining a coordinate control mode can be implemented in the form of hardware and / or software. The device for determining a coordinate control mode can be configured in an electronic device, and the electronic device can be an information processing end. As Figure 7 shown, the method includes:

[0085] S410. Receive the absolute coordinates when the display icon corresponding to the input device sent by the output node is displayed at a preset position.

[0086] Exemplarily, in order to determine whether the current display screen supports cross-screen display through the display effect of the display icon corresponding to the input device, the display icon corresponding to the input device can be made to be displayed at a preset position on the display interface, and the absolute coordinates when the display icon is displayed at the preset position are determined, so as to determine the position where the display icon should be displayed on the display interface theoretically if it can support cross-screen display. The output node sends the absolute coordinates to the information processing end, and the information processing end receives the absolute coordinates sent by the output node.

[0087] S420. Convert the absolute coordinates into logical coordinates in the absolute coordinate mode.

[0088] Exemplarily, in order to determine whether the current display screen supports cross-screen display through the display effect of the display icon corresponding to the input device, the display icon corresponding to the input device can be made to be displayed at a preset position on the display interface, and the absolute coordinates when the display icon is displayed at the preset position are determined, so as to determine the position where the display icon should be displayed on the display interface theoretically if it can support cross-screen display. Assuming that the display screen supports cross-screen display, the information processing end converts the absolute coordinates into logical coordinates according to the absolute coordinate mode matching the cross-screen display.

[0089] In the embodiment of the present application, converting the absolute coordinates into logical coordinates in the absolute coordinate mode includes:

[0090] Determining the maximum logical coordinates of the input device according to the report descriptor;

[0091] In the absolute coordinate mode, determining the logical coordinates according to the absolute coordinates, the display resolution, and the maximum logical coordinates.

[0092] Exemplarily and specifically, the information processing end may include a virtual keyboard and mouse node for performing keyboard and mouse simulation. The virtual keyboard and mouse node determines the maximum logical coordinates of the keyboard and mouse movement according to the report descriptor. In the absolute coordinate mode, according to the absolute coordinates, the display resolution, and the maximum logical coordinates, the logical coordinates corresponding to the absolute coordinates are determined. The maximum logical coordinates are the maximum coordinates that the display icon corresponding to the input device can reach on the display interface supported by the display. As Figure 3 shown, if there are two horizontally spliced display screens that support cross-screen display, the display icon of the mouse can be displayed on the two display screens, and the maximum coordinates that the display icon can reach are the lower right corner of display screen B, and the logical coordinates of this point are the maximum logical coordinates. If the maximum logical coordinates of the input device are (32767, 32767), then the logical coordinates of this point are (32767, 32767). The lower right corner of display screen A is located at the midpoint of the lower edge, and the logical coordinates are (16383, 32767). According to the absolute coordinates and the display resolution, the position of the display icon on the display interface can be determined, and then according to the position and the maximum logical coordinates, the logical coordinates of the display icon can be determined.

[0093] In the embodiment of the present application, in the absolute coordinate mode, determining the logical coordinates according to the absolute coordinates, the display resolution, and the maximum logical coordinates includes:

[0094] Determining the display ratio of the absolute coordinates on the display interface according to the absolute coordinates and the display resolution in the same dimension; wherein, the same dimension includes the horizontal dimension or the vertical dimension;

[0095] Determining the logical coordinates corresponding to this dimension according to the product of the maximum logical coordinates in this dimension and the display ratio.

[0096] As Figure 3As shown, if the absolute coordinates of the mouse are (959, 539) and the display resolution is 1920*1080, it can be determined that the display icon of the mouse should be located at the midpoint of display screen A. According to this position and the maximum logical coordinates, the logical coordinates of the display icon are calculated as (8191, 16383), where. Specifically, in the horizontal dimension, the absolute coordinate is 959 and the display resolution is 1920. The absolute coordinate is encoded starting from 0, so 959 represents the 960th pixel point. Dividing 960 by 1920 gives the display ratio of the horizontal coordinate in the display interface as 1 / 2. Multiplying the maximum logical coordinate in the horizontal dimension by the display ratio gives the logical pixel points in the horizontal dimension. Since the logical coordinates also start from 0, subtracting 1 from the logical pixel points in the horizontal dimension gives the logical coordinates in the horizontal dimension, that is, 16384 / 2 - 1. The same applies to the vertical dimension, and 16383 is obtained as (32768 / 2) - 1. The virtual keyboard and mouse node sends the logical coordinates to the terminal, such as Figure 2 the computer host in. The instruction sent can be "echo–n–e“\x00\xff\x1f\xff\x3f\x00”> / dev / hidg0", where \xff\x1f\ represents the abscissa 8191 of the logical coordinates, and \xff\x3f represents the ordinate 16383 of the logical coordinates. dev / hidg0 represents the character device simulated by the virtual keyboard and mouse node for the mouse.

[0097] S430. Determine the display image according to the logical coordinates, and send the display image to the corresponding display device for display, so that the display device determines the actual coordinates of the display icon in the display image and sends them to the output node.

[0098] Exemplarily, after the information processing end converts the absolute coordinates into logical coordinates, it generates a display image according to the logical coordinates of the display icon and sends the display image to the display device for display. Specifically, the computer host of the information processing end converts the logical coordinates into coordinates in the display interface, generates a display image containing the display icon, and sends the display image to the display device for display. The display device receives the display image for decoding and display, captures the display graphics of the display interface using a programming language and a graphics library, and determines the actual coordinates of the display graphics. The display device sends the actual coordinates of the display graphics to the output node, and the output node receives the actual coordinates sent by the display device.

[0099] An embodiment of the present application provides a method for determining a coordinate control mode, which receives memory operation data and a function call path sent by a device under test; wherein, the memory operation data and the function call path are obtained by the device under test during the code running stage, and the function call path is determined by the device under test according to the call relationship and function identifier of each function in the code during the code compilation stage; and determines a coordinate control mode according to the memory operation data and the function call path. Whether a leak occurs is accurately detected through the memory operation data, and the call stage causing the memory leak is accurately located according to the function call path scanned and generated during the compilation stage.
