Detailed Description

The terminology used in the description of the embodiments section of the present application is for the purpose of describing particular embodiments of the present application only and is not intended to be limiting of the present application.

In the prior art, a method for assisting a user in finding a cursor in a single screen scene is provided, for example, when the user shakes a mouse quickly in an MAC OS system, the cursor is displayed on a screen in an enlarged manner to help the user find the cursor; alternatively, in a Windows system, a function option of "displaying the position of the pointer when pressing the CTRL key" is provided, and after the user selects the function, the user presses the CTRL key, and a circle shrinking inward appears on the periphery of the cursor, thereby indicating the position of the cursor.

However, the method is only suitable for a single display screen, and in a multi-screen display scene, a user still needs to find the display screen to which the cursor belongs first to find the cursor, so that the user finds the cursor slowly and difficultly, and the user experience is affected.

Therefore, the cursor prompting method and the host provided by the embodiment of the application can assist a user to relatively quickly find the cursor on the display interface of the display screen in a multi-screen shared keyboard and mouse scene, and improve user experience.

The method provided by the embodiment of the application can be applied to the host. The host herein refers to a main body part of the electronic device excluding input and output devices such as a display screen, a keyboard, a mouse, and the like.

For example, fig. 1 shows a schematic structural diagram of a host 100.

The host 100 may include a processor 110, an antenna, a wireless communication module 120, an internal memory 121, and the like.

It is to be understood that the illustrated structure of the embodiment of the present invention does not specifically limit the electronic device 100. In other embodiments of the present application, electronic device 100 may include more or fewer components than shown, or some components may be combined, some components may be split, or a different arrangement of components. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

Processor 110 may include one or more processing units, such as: the processor 110 may include an Application Processor (AP), a modem processor, a Graphics Processing Unit (GPU), an Image Signal Processor (ISP), a controller, a video codec, a Digital Signal Processor (DSP), a baseband processor, and/or a neural-Network Processing Unit (NPU), etc. The different processing units may be separate devices or may be integrated into one or more processors.

The controller can generate an operation control signal according to the instruction operation code and the timing signal to complete the control of instruction fetching and instruction execution.

A memory may also be provided in processor 110 for storing instructions and data. In some embodiments, the memory in the processor 110 is a cache memory. The memory may hold instructions or data that have just been used or recycled by the processor 110. If the processor 110 needs to reuse the instruction or data, it can be called directly from the memory. Avoiding repeated accesses reduces the latency of the processor 110, thereby increasing the efficiency of the system.

In some embodiments, processor 110 may include one or more interfaces. The interface may include a universal asynchronous receiver/transmitter (UART) interface, a Mobile Industry Processor Interface (MIPI), and the like.

The UART interface is a universal serial data bus used for asynchronous communications. The bus may be a bidirectional communication bus. It converts the data to be transmitted between serial communication and parallel communication. In some embodiments, a UART interface is generally used to connect the processor 110 with the wireless communication module 160. For example: the processor 110 communicates with a bluetooth module in the wireless communication module 160 through a UART interface to implement a bluetooth function.

The MIPI interface may be used to connect the processor 110 with peripheral devices such as a display screen. The MIPI interface includes a Camera Serial Interface (CSI), a Display Serial Interface (DSI), and the like. In some embodiments, processor 110 and the camera communicate via a CSI interface, enabling host 100 to control the camera's shooting function. The processor 110 and the display screen communicate through the DSI interface, and the host 100 controls the display function of the display screen.

It should be understood that the interface connection relationship between the modules according to the embodiment of the present invention is only an exemplary illustration, and does not form a structural limitation on the host 100. In other embodiments of the present application, the host 100 may also adopt different interface connection manners or a combination of multiple interface connection manners in the above embodiments.

The internal memory 121 may be used to store computer-executable program code, which includes instructions. The internal memory 121 may include a program storage area and a data storage area. The storage program area may store an operating system, an application program (such as an image playing function) required by at least one function, and the like. The storage data area may store data (such as image data) created during use of the host 100, and the like. In addition, the internal memory 121 may include a high-speed random access memory, and may further include a nonvolatile memory, such as at least one magnetic disk storage device, a flash memory device, a universal flash memory (UFS), and the like. The processor 110 executes various functional applications of the electronic device 100 and data processing by executing instructions stored in the internal memory 121 and/or instructions stored in a memory provided in the processor.

The wireless communication module 160 may provide a solution for wireless communication applied to the host 100, including Wireless Local Area Networks (WLANs) (e.g., wireless fidelity (Wi-Fi) networks), Bluetooth (BT), Global Navigation Satellite System (GNSS), Frequency Modulation (FM), Near Field Communication (NFC), Infrared (IR), and the like. The wireless communication module 160 may be one or more devices integrating at least one communication processing module. The wireless communication module 160 receives electromagnetic waves via an antenna, performs frequency modulation and filtering processing on electromagnetic wave signals, and transmits the processed signals to the processor 110. Wireless communication module 160 may also receive signals to be transmitted from processor 110, frequency modulate them, amplify them, and convert them into electromagnetic waves via an antenna for radiation.

The display screen described in the embodiments of the present application below is used to display images, videos, and the like. The display screen includes a display panel. The display panel may adopt a Liquid Crystal Display (LCD), an organic light-emitting diode (OLED), an active-matrix organic light-emitting diode (active-matrix organic light-emitting diode, AMOLED), a flexible light-emitting diode (FLED), a miniature, a Micro-oeld, a quantum dot light-emitting diode (QLED), and the like.

The host and the display screen in the embodiment of the application may be disposed in the same physical entity, for example, a PAD (PAD), an integrated Personal Computer (PC), and other electronic devices; alternatively, the host and display may be physically separated and exist as separate entities, such as a desktop computer.

For convenience of understanding, the following embodiments of the present application will specifically describe the method provided by the embodiments of the present application by taking a host having a structure shown in fig. 1 as an example, and combining the drawings and application scenarios.

First, an exemplary explanation will be given of a cursor in the embodiment of the present application. The cursor is generated after the computer begins to use the mouse in order to identify the mouse position on the graphical interface, the graphical identification icon of the mouse position. The specific graph of the cursor may change based on the difference of the display interface on the display screen, for example, when the text input interface performs text input, the cursor may be a vertical line that flickers regularly, the cursor is displayed as an arrow under some interfaces, and when moving to a certain link, the cursor may change into a small hand, and so on. The user can realize the movement control of the cursor through the operation of an input device such as a mouse, a keyboard, a virtual keyboard, a touch display screen and the like.

An application scenario of the cursor prompting method according to the embodiment of the present application is illustrated in fig. 2 and fig. 3.

Fig. 2 is an exemplary diagram of an application scenario of the cursor prompting method according to the embodiment of the present application. The scene is an extended screen scene, and comprises: the mouse comprises a host 21, a mouse 22 and n display screens 23, wherein n is an integer greater than or equal to 2; in fig. 2, n is 3, that is, there are 3 display screens as an example. Wherein, the host 21 is respectively connected with each display screen 23, and the host 21 is connected with the mouse 22; the connection between the host 21 and each display screen 23 can be a wireless connection or a wired connection; the connection between the host 21 and the mouse 22 may be a wireless connection or a wired connection. If the connection is wireless, the specific connection mode is not limited in the embodiment of the application, and may be, for example, WiFi, bluetooth, or the like. The host 21 may respectively determine interface data to be displayed by each display screen 23 of the n display screens 23, and send the interface data to each display screen 23 for display; a cursor 24 (an arrow in the figure) corresponding to the mouse 22 can be moved on the n display screens 23 based on the operation of the mouse 22 by the user.

Fig. 3 is a diagram illustrating another application scenario of the cursor prompt method according to the embodiment of the present application. The scene is a keyboard and mouse sharing scene, which comprises the following steps: n hosts 31, a display screen 32 corresponding to each host 31, and a mouse 33; the hosts 31 are connected with each other, the hosts 31 are connected with the corresponding display screens 32, and the mouse 33 is connected with one host 31 in the n hosts 31; the connection may be a wireless connection or a wired connection, and if the connection is a wireless connection, the specific connection mode is not limited in the embodiment of the application, and may be, for example, WiFi, bluetooth, or the like. The host 31 determines interface data to be displayed by the display screen 32 corresponding to the host 31, and sends the interface data to the corresponding display screen 32 for displaying; a cursor 34 (an arrow in the figure) corresponding to the mouse 33 can move on the n display screens 32 based on the operation of the mouse 33 by the user; the host connected with the mouse 33 receives displacement information sent by the mouse in real time according to a certain period, the displacement information of the mouse can be shared by the host connected with the mouse to other hosts, such as a host corresponding to a display screen to which a cursor belongs, and the host corresponding to the display screen to which the cursor belongs adjusts the position of the cursor 34 on the display screen based on the displacement information of the mouse.

It should be noted that the host in the above application scenario may also be connected to other input devices besides a mouse, such as a keyboard, and a cursor may also move on each display screen based on a user operating the keyboard.

Hereinafter, a method for establishing a coordinate system of each display screen in the embodiment of the present application is exemplarily described with reference to fig. 4.

The display screens are typically regular rectangles, and each of the n display screens shown in fig. 2 and 3 may establish its own coordinate system. For ease of calculation in the subsequent steps, the n display screens are preferably set up in the same way as the coordinate system. For example, as shown in fig. 4, for each display screen, the angle at which the user views the display screen is taken as the coordinate system origin O of the display screen, the upper edge of the display screen is the x-axis, the direction in which the x-axis points to the right side is the positive x-axis direction, the left edge of the display screen is the y-axis, and the downward direction of the y-axis is the positive y-axis direction. Accordingly, each pixel point on the display screen can identify its position in the display screen by the coordinate (x, y).

It should be noted that the above-mentioned coordinate system establishing method is only an example, and is not used to limit the establishing method of the display screen coordinate system.

Since there are multiple display screens and the cursor can move among the multiple display screens, the positional relationship information between the multiple display screens can be set in the host in advance, and the following describes an exemplary setting method of the positional relationship information between the n display screens in the embodiment of the present application.

For the application scenario shown in fig. 2, the positional relationship information between the n display screens may be set in the host 21 in advance; for the application scenario shown in fig. 3, it is necessary to set positional relationship information between the n display screens 42 in at least one host 31 of the n hosts 31 in advance. Optionally, the position relationship information between the display screens is set based on the coordinate system of the display screens, for example: selecting one display screen from the n display screens as a main display screen, wherein a coordinate system of the main display screen is called a main coordinate system, calculating coordinates of an origin of a coordinate system of the non-main display screen in the main coordinate system according to display parameters of the display screens, such as width, height and physical relative position relationship between the display screens, and correspondingly recording position relationship information between the display screens into the following form: display screen M { X, Y, Width, Height }. Wherein, X is the abscissa of the origin of coordinates of the display screen M in the main coordinate system, Y is the ordinate of the origin of coordinates of the display screen M in the main coordinate system, Width is the screen Width of the display screen M (the side length of the display screen M in the X-axis direction of the coordinate system of the display screen M), and can be represented by the number of pixel points in the X-axis direction, and Height is the screen Height of the display screen M (the side length of the display screen M in the Y-axis direction of the coordinate system of the display screen M), and can also be represented by the number of pixel points in the Y-axis direction. Hereinafter, the display screen M { X, Y, Width, Height } is referred to as relative position information of the display screen M.

By way of example: referring to fig. 5, assuming that a display screen 51 and a display screen 52 are provided, the display screen 51 is a main display screen, and the physical position relationship between the display screen 52 and the display screen 51 is as shown in fig. 6, the recording of the position relationship between the display screen 51 and the display screen 52 is as follows: display screen 1{ X ═ 0, Y ═ 0, Width ═ W1, Height ═ H1}, display screen 2{ X ═ W1, Y ═ H3, Width ═ W2, Height ═ H2 }. When the total number of the display screens in fig. 3 and 4 exceeds 2, the setting of the position relationship may refer to the example in fig. 5, and will not be described in detail.

In the following embodiments, a coordinate system establishing method shown in fig. 4 and a relative positional relationship setting method between display screens shown in fig. 5 will be described as examples.

It should be noted that, when the positional relationship information between the display screens is known, and the x-axis and the y-axis of each display screen coordinate system are parallel to each other, if the coordinate of a certain pixel point in one display screen coordinate system is known, the coordinate of the certain pixel point in the other display screen coordinate system can be calculated. For example, knowing the coordinates of a certain pixel in the coordinate system of the display screen 1, the coordinates of the pixel in the main coordinate system can be calculated. The detailed description of the calculation method is omitted here.

Fig. 6 and 11 are embodiments of cursor prompt methods for the application scenario shown in fig. 2.

Fig. 6 is a flowchart of an embodiment of a cursor prompting method according to the present application, which may be applied to the host 21 shown in fig. 2, and as shown in fig. 6, the method may include:

step 601: the host computer detects the cursor searching operation and obtains the position information of the cursor.

The embodiment of the present application is not limited to the specific implementation of the cursor searching operation. For example: correspondingly, for the host, the host can judge that the moving distance of the mouse in unit time length reaches a preset threshold value based on the displacement information of the mouse, and then the host detects the cursor searching operation; or, the cursor searching operation may be, in a user plane, that the user presses a certain key on an input device connected to the host, for example, a keyboard or a virtual keyboard, for a preset number of times, for example, the user presses a ctrl key 3 times or more than 3 times, and correspondingly, for the host, the host determines, based on a received key pressing event sent by the input device, that the number of pressing events of a specified key received in a unit time duration reaches the preset number of times, and then the host detects the cursor searching operation. The specific value of the unit time length is not limited in the embodiment of the present application.

The position information of the cursor is used for recording the position of the cursor on the display screen. The position information of the cursor may be: coordinates of the cursor in the master coordinate system, e.g., (x1, y 1); or information of the display to which the cursor belongs and coordinates of the cursor in the coordinate system of the display to which the cursor belongs, for example (display 1, (x2, y 2)). The coordinates of the cursor in a coordinate system can be identified by the coordinates of a preset point on the cursor graph, for example, the center point of the cursor graph in the coordinate system. For example, assuming that the cursor graph is an arrow as shown in fig. 2 and fig. 3, the position information of the cursor may be represented by coordinates of a center point of the arrow in a coordinate system, which may also be referred to as coordinates of the cursor in the coordinate system, for example, coordinates of the center point of the arrow in the main coordinate system are (x3, y3), and the position information of the cursor may be (x3, y3), which may also be referred to as coordinates of the cursor in the main coordinate system are (x3, y 3).

Step 602: the host computer displays a first visual indication element on a display screen except the display screen to which the cursor belongs, and the first visual indication element is used for indicating the position of the cursor.

For the convenience of the following description, the display screen on which the first visual indication element is displayed, that is, the display screen other than the display screen to which the cursor belongs, will be referred to as the first display screen.

Wherein the first visual indication element may comprise: a first graphic having a directional directivity to a cursor position; alternatively, the first visual indication element may comprise: and animation having directional directivity to the cursor position. The graphic or animation has directional directivity pointing to the cursor position, which means that the user can get a direction when seeing the graphic or animation, the direction being a direction pointing to the cursor position.

Optionally, the first visual indication element may comprise an animation comprising: a second graphic and a first motion trajectory of the second graphic. The second graph has direction directivity pointing to the cursor position, and/or the first motion track of the second graph has direction directivity pointing to the cursor position.

Step 603: and the host judges that the first ending condition is met and ends the display of the first visual indication element.

Optionally, the determining, by the host, that the first end condition is satisfied may include: the host computer detects that the cursor searching operation is finished, or the host computer judges that the display duration of the first visual indication element reaches a first preset duration.

Optionally, if the first visual indication element comprises an animation, the animation comprises: the second graph and the first motion track of the second graph, and the determining, by the host, that the first end condition is met may include: the host computer judges that the second graph in the first visual indication element moves to the end point of the first movement track. The second graph moves to the end point of the first motion track, which shows that the second graph has completed one motion from the start point to the end point of the first motion track, and a complete display of the animation can be considered to be completed.

Referring to the description in step 601, when the host detects that the cursor searching operation is finished, the cursor searching operation can be finished by the user shaking the mouse or quickly moving the mouse on the user plane, and correspondingly, for the host, the host can judge that the moving distance of the mouse in unit time length is smaller than the preset threshold value based on the displacement information of the mouse, and then the host detects that the cursor searching operation is finished; or, the end of the cursor searching operation may be, in terms of a user plane, that the user presses a certain key on an input device connected to the host, for example, a keyboard or a virtual keyboard, and for example, the user does not press a ctrl key any more, and correspondingly, for the host, the host determines that the number of times of pressing events of the specified key received in the unit time duration is less than the preset number of times, and then the host detects that the cursor searching operation is ended.

For the implementation of step 602, the following is explained:

if the first visual indication element comprises a first graphic:

the display position of the first visual indication element on the first display screen is not limited by the embodiment of the application. In order to make it easier for the user to position the cursor position according to the direction indicated by the first visual indication element, optionally, the display position of the first visual indication element may be located on an edge of the first display screen closest to the display screen to which the cursor belongs, such as a midpoint of the edge, or an intersection point of a connecting line between the cursor position and a center point of the first display screen and the edge; alternatively, to make the first visual indication element more noticeable to the user, the display position of the first visual indication element may be located at a relatively special position on the display screen, such as the center point of the first display screen. However, it should be noted that the first visual indication element may be disposed at other positions on the first display screen to perform an indication function of the first visual indication element on the cursor position.

The specific shape of the first graphic is not limited in the embodiment of the present application as long as the first graphic has directional directivity pointing to the cursor position, and alternatively, in order to make it easier for the user to recognize the direction indicated by the graphic, the first graphic may be an arrow pointing to the cursor position.

Similarly to the above description about the cursor position, the display position of the first visual indication element may be represented by the position of one of the pixels in the first visual indication element. For example, if the first graphic is an arrow, the display position of the arrow, that is, the position information of the first graphic or the first visual indication element, may be represented by the position of the pixel point at the tip of the arrow.

The color of the first graphic is not limited in the embodiments of the present application, and is preferably a color that is easily noticeable to a user visually, for example, red.

By way of example: referring to fig. 7A, a first graphic as a first visual indication element is an arrow 721, the display screen 71 is a display screen to which a cursor belongs, the display screen 72 is a display screen to which the arrow 721 belongs, that is, the first display screen, the cursor is located at a point a on the display screen 71 (for example, a cursor center point is used to identify a cursor position in fig. 7), the center point of the display screen 72 is a point B, a tip pixel point of the arrow 721 is located at an intersection point C of a straight line AB and a sideline of the display screen 72, and a line included by the arrow 721 coincides with the straight line AB.

Referring to fig. 7B, unlike fig. 7A, the point of the tip pixel of the arrow 721 is located at the midpoint D of the edge of the display screen 71 near the cursor position, and the line included in the arrow 721 coincides with the straight line AD.

Referring to fig. 7C, unlike fig. 7A and 7B, the tip pixel point of the arrow 721 is located at the point B of the center point of the display screen 71, and the line included in the arrow 721 coincides with the straight line AB.

It should be noted that, the adjacent display screens 71 and 72 in fig. 7A and 7B are only examples, and the display screens 71 and 72 may not be adjacent, for example, other display screens are disposed in the middle, and the implementation thereof may refer to fig. 7A and 7B, which is not described herein.

When the first graphic is determined, the host computer displays the first graphic on the first display screen, it is necessary to determine the display position of the first graphic on the first display screen first, and then may determine the indication direction of the first graphic, that is, the direction in which the display position points to the cursor position, and then the host computer may display the first graphic on the display position according to the indication direction, thereby completing the display of the first visual indication element.

The host determines that the display position of the first graph on the first display screen can be divided into two cases, one is that the display position information of the first graph is obtained by dynamic calculation, for example, the position of a pointed pixel point of an arrow in the example shown in fig. 7A and 7B is obtained by real-time calculation according to the position of a cursor; second, the display position information of the first graph is preset by the host, for example, the center point of the pointed pixel point of the arrow in the example shown in fig. 7C, which is located on the first display screen, is preset by the host. The following respectively illustrates the determination method of the display position of the first graphic on the first display screen in different cases:

in a possible implementation manner, a first pixel point may be preset in the host, where the first pixel point may be any pixel point on the first display screen, and the position information of the first pixel point is stored in advance (for example, a coordinate of the first pixel point in a coordinate system of the first display screen); accordingly, the host computer determining display position information for the first visual indication element may include:

acquiring position information of a first pixel point; calculating the position information of the first intersection point according to the position information of the cursor and the position information of the first pixel point; the first intersection point is an intersection point of a first straight line and a first display screen sideline, and the first straight line is a straight line passing through the cursor position and the first pixel point.

For example, fig. 7A may correspond to this implementation, where the first pixel point in fig. 7A is a central point of the first display screen, the first straight line is a straight line AB, and the first intersection point is a point C in fig. 7A.

At this time, the cursor position, the first intersection point and the first pixel point are on the same straight line, and the direction in which the first intersection point points to the cursor position, that is, the direction in which the first pixel point points to the cursor position, can be used as the indication direction of the first graph. Accordingly, the host may display a first graphic based on the pointing direction and the display position, such as shown in FIG. 7A.

A calculation method of the position information of the first intersection point is exemplified. The calculation of the position information of the first intersection point may be performed in the master coordinate system. The host can determine the coordinate of the cursor in the main coordinate system according to the position information of the cursor, determine the coordinate of the first pixel in the main coordinate system according to the position information of the first pixel, the host can calculate the coordinate of the first intersection point in the main coordinate system according to the coordinate of the cursor in the main coordinate system and the coordinate of the first pixel in the main coordinate system by combining the position relation information between the display screens preset in the host, the coordinate can identify the position of the first intersection point, the host can determine the position of the first intersection point on the first display screen conveniently, the coordinate of the first intersection point in the main coordinate system can be converted into the coordinate of the first intersection point in the coordinate system of the first display screen, and the coordinate can identify the position of the first intersection point. Referring to fig. 8, it is assumed that the cursor is located on the display screen 71, and the coordinate system of the display screen 71 may be a main coordinate system or not, the coordinate of the cursor in the main coordinate system is assumed to be represented by the coordinate of the cursor center point a in the main coordinate system, specifically, (X1, Y1), the first pixel point is assumed to be the center point B of the first display screen (i.e., the display screen 72), the positional relationship information of the display screen 72 recorded in the positional relationship information between the display screens is (X ═ W1, Y ═ H3, Width ═ W2, Height ═ H2), the first intersection point is a point C, a straight line parallel to the Y axis is drawn through the point a, a straight line parallel to the X axis is drawn through the point B, two straight lines intersect at the point D, the line segment AD is perpendicular to the line segment DB, the intersection point of the line segment DB and the display screen 72 is the point E, the line segment CE is perpendicular to the line segment DB, and the graph is a graphThe ordinate of the point C of the first intersection point can be calculated based on the proportional relation of the side lengths of the trigonometric function or the similar triangle:

and the abscissa of the point C is W1, so that the coordinates (W1, h4) of the point C in the main coordinate system are obtained. The coordinates may also be converted to coordinates (0, h4-h3) in the coordinate system of the display screen 72 to facilitate the host computer displaying the first graphic at point C of the display screen 72.

In another possible implementation manner, the host may select, based on a positional relationship between the cursor position and the display screen, an edge line of the display screen closest to the cursor position, and use a certain preset pixel point, such as a midpoint, of the edge line as a display position of the first graphic; at this time, the determining, by the host computer, the display position information of the first graphic may include:

and acquiring position information of a preset second pixel point on a first edge of the first display screen, and taking the position information of the second pixel point as display position information of the first graph, wherein the first edge is the edge of the first display screen closest to the position of the cursor.

At this time, the direction in which the second pixel points to the cursor position may be used as the indication direction of the first graphic. Accordingly, the host may display a first graphic based on the pointing direction and the display position, such as shown in FIG. 7B.

In another possible implementation manner, the host may use the position information of a certain preset pixel point of the first display screen, for example, a central point, and then the host may directly use the position information of the preset pixel point as the display position information of the first graphic.

At this time, the direction in which the center point of the display screen points to the cursor position may be taken as the indication direction of the first graphic. Accordingly, the host may display a first graphic based on the pointing direction and the display position, such as shown in FIG. 7C.

If the visual indication element is an animation, the animation comprises: the second graph and the first motion track of the second graph are as follows:

if the second graphic in the animation has directional directivity pointing to the cursor position, the second graphic may be implemented with reference to the related description of the first graphic, for example, the second graphic may be an arrow pointing to the cursor position, and at this time, the motion trajectory of the second graphic is not limited, for example, the animation may be: the arrow pointing to the cursor position continuously flickers or continuously shakes; for example, animation effects such as flickers and shakes are added to the arrows shown in fig. 7A to 7C, and animation having directional directivity toward the cursor position can be obtained.

If the first motion trail of the second graph in the animation has the directional directivity of the directional cursor position, the first motion trail can be a vector starting from a preset fourth pixel point on the first display screen along the directional cursor position direction of the preset pixel point until the edge of the first display screen, the fourth pixel point can be a point in the edge of the first display screen, in order to make the path of the animation relatively long and the visual effect better, the center point of the first display screen can be used as the preset fourth pixel point, namely, the starting point of the first motion trail, the example is mentioned: the animation as the first visual indication element may be that the second graphic starts from a center point of the first display screen, and continuously approaches the cursor position according to a direction pointing to the cursor position until reaching an edge line of the first display screen; for example, referring to FIG. 9A, the second graph is love 922, which starts from the center point B of the display screen 92 and continues to approach the cursor position A along the direction pointing to the cursor position A from the center point B until the point C on the edge line of the display screen 92, which is the intersection of the straight line AB and the display screen 92. The calculation of the position information of the intersection point C can refer to the related description in fig. 8, which is not described herein.

If the second graph included in the animation and the first motion trajectory of the second graph both have directional directionality pointing to the cursor position, the method for determining the indication direction of the second graph and the method for determining the first motion trajectory of the second graph may refer to the above-mentioned related description when only the first motion trajectory of the second graph or the second graph has directional directionality, and will not be described herein again. For example, the animation may be that an arrow pointing to the cursor position is continuously closer to the cursor position in the direction pointing to the cursor position. For example, referring to FIG. 9B, unlike FIG. 9A, the second graphic is arrow 921, with arrow 921 pointing to the cursor position.

Optionally, in step 602, in addition to displaying the first visual indication element on a display screen other than the display screen to which the cursor belongs, indicating the cursor position to the user, some effect display may be performed on the display screen to which the cursor belongs, so that the user can find the cursor more quickly. In this case, the step 602 may further include: and the host machine performs highlighting of preset effects on the display interface and/or the cursor on the display screen to which the cursor belongs. Highlighting of the display interface may include, but is not limited to: highlighting a display interface, flickering the display interface, and the like. Highlighting of the cursor may include, but is not limited to: and (4) magnifying the cursor to display, changing the color of the cursor to be a relatively striking color such as red, cursor flashing and the like. By highlighting the display interface on the display screen to which the cursor belongs, the user can find the display screen to which the cursor is positioned more easily, and the cursor is highlighted, so that the user can find the cursor more easily.

Alternatively, if the animation as the first visual indication element includes a first motion track having a directional directivity pointing to the cursor position, for example, as shown in fig. 9A and 9B, in order to make such directional directivity more clear and complete, the host may control the associated display screen to relay the animation of the same second graphic moving from the preset pixel point of the first display screen to the cursor position. For example, as shown in fig. 9C, it is assumed that the display screens 91 to 93 are included, the display screens 91 to 93 are sequentially arranged, the cursor is at a point a in the display screen 91, the points C, D, E, F are respectively intersections of the straight line AB and the side lines of the display screens, the arrow 931 displayed on the display screen 93 moves from the point B to the point C along the BC direction, then the arrow 931 displayed on the display screen 92 moves from the point D to the point E along the DE direction, and finally the arrow 931 displayed on the display screen 91 moves from the point F to the point a, and the movement trajectory of the arrow 931 from the center point B of the display screen 93 to the position a where the cursor is located is completed. For the display screens 91-93, the display screens 91-93 respectively display a visual indication element, the visual indication element comprises the same second graph, and the motion tracks of the second graph are on the same straight line.

At this time, if a third display screen exists between the first display screen and the second display screen to which the cursor belongs, the host computer can calculate the position information of two intersection points of the sideline of the third display screen and the straight line passing through the preset pixel point and the cursor position based on the position information of the preset pixel point and the position information of the cursor on the first display screen, and a vector obtained by taking the intersection point close to the cursor position as a terminal point and taking the intersection point far from the cursor position as a starting point is taken as a motion track of the second graph in the third display screen; for example, in fig. 9C, the display screen 92 is a third display screen with respect to the display screen 91 and the display screen 93, two intersection points of the straight line AB and an edge line of the display screen 92 are calculated as points D and E, respectively, and a vector having the point D as a starting point and the point E as an ending point is calculated as a motion trajectory of the arrow 931 on the display screen 92.

For the second display screen to which the cursor belongs, the host computer can calculate the intersection point of the sideline of the second display screen and the straight line passing through the preset pixel point and the cursor position, the vector taking the intersection point as a starting point and the cursor position as an end point is taken as the motion track of the second graph in the second display screen, and the host computer controls the relay display of the second graph to the cursor position after the first display screen display animation is finished, the third display screen display animation and the second display screen display animation finally. For example, in fig. 9C, the second display screen is the display screen 91, an intersection point of a side line of the second display screen and a straight line passing through a preset pixel point and a cursor position is F, and a motion trajectory of the arrow 931 in the display screen 91 is a vector having F point as a starting point and a point a as an end point.

Hereinafter, the above embodiments are exemplarily described from the viewpoint of a User Interface (UI) Interface.

Referring to fig. 10A, in a portion 1010 of fig. 10, a cursor 101 is located on a display screen 1011, and a host detects a cursor finding operation; then, see section 1020, display screen 1012 displays arrow 102 near the edge of cursor 101, arrow 102 pointing to the position of cursor 101, display screen 1013 displays arrow 103 near the edge of cursor 101, arrow 103 pointing to the position of cursor 101; referring to section 1030, the host determines that the cursor-seeking operation is finished and the arrows on display screen 1012 and display screen 1013 are no longer displayed.

Referring to fig. 10B, unlike fig. 10A in which the position of the cursor 101 is indicated using a static arrow, in fig. 10B in which the position of the cursor 101 is indicated using an animation, see part 1021, the arrow 102 displayed on the display screen 1012 gradually approaches the cursor 101 from the center point of the display screen 1012 in a direction pointing to the position of the cursor 101, and the arrow 103 displayed on the display screen 1013 gradually approaches the cursor 101 from the center point of the display screen 1013 in a direction pointing to the position of the cursor 101.

Referring to fig. 10C, unlike fig. 10B, in the added part 1022, the display screen 1011 may also perform relay display of the arrow 102 and the arrow 103, so that the movement tracks of the arrow 102 and the arrow 103 extend to the position of the cursor 101, and the indication of the cursor position is more explicit.

Different from the embodiment shown in fig. 6, when the motion trajectory of the second graphic in the first visual indication element has directional directivity, in order to better attract the visual attention of the user, so that the user can effectively view the motion trajectory of the second graphic in the first visual indication element, the host may further add a display visual alert element before displaying the first visual indication element on the first display screen, where, as shown in fig. 11, step 602 may include:

step 1101: the host displays a visual alert element on the first display screen.

The visual reminding element is mainly used for arousing the visual attention of the user through the visual reminding element, so that the user can effectively watch the motion trail of the second graph in the first visual indication element and find the cursor position. The visual alert element may have a directional directionality toward the cursor position, such as an arrow toward the cursor position in the previous example, or may not have a directional directionality toward the cursor position, such as a mirror image cursor or the previous example. Optionally, the visual alert element may be a second graphic included in the animation as the first visual indication element. Optionally, the host displays the visual alert element at the start of the first motion profile.

Step 1102: the host determines that the second end condition is satisfied, and proceeds to step 602.

Wherein, the determining, by the host, that the second end condition is satisfied may include: detecting that the cursor searching operation is finished; or judging that the display time length of the visual reminding element reaches a second preset time length.

At this time, the determining, by the host computer in step 603, that the first end condition is met may include:

judging that the display duration of the visual indication element reaches a first preset duration; alternatively, the first and second electrodes may be,

Hereinafter, the above-described embodiments are exemplarily described from the UI interface point of view.

Referring to fig. 12, unlike the embodiment shown in fig. 10B, a portion 1210 is added, wherein taking the example that the visual alert element is an arrow in the first visual indication element, referring to the portion 1210, the display screen 1012 displays the arrow 102 at the center point, the arrow 102 points to the position of the cursor 101, the display screen 1013 displays the arrow 103 at the center point, and the arrow 103 points to the position of the cursor 101.

It should be noted that, in the above embodiment, when the visual prompting element and the visual indication element are displayed on the display screen, a transparent window may be newly established, the transparent window is displayed on the uppermost layer of all windows, and the visual prompting element and the visual indication element are displayed in the newly established transparent window.

The implementation of the cursor prompting method of the present application is described with respect to the system architecture shown in fig. 4.

Fig. 13 is a structural diagram of a cursor prompting method according to another embodiment of the present application, and for convenience of description, a host corresponding to a display screen to which a cursor belongs is referred to as a first host, and hosts other than the first host are referred to as second hosts. The number of the second hosts may be one or more, and is related to the value of n in the system architecture shown in fig. 4.

As shown in fig. 13, the method may include:

step 1301: and the second host receives the position information of the cursor, and the position information of the cursor is sent after the first host detects the cursor searching operation.

Step 1302: and the second host displays the first visual indication element on the display screen corresponding to the second host according to the position information of the cursor.

Step 1303: and the second host judges that the first ending condition is met, and ends the display of the first visual indication element on the display screen corresponding to the second host.

Unlike the embodiment shown in fig. 13, in order to better attract the visual attention of the user, a visual reminding element may be further displayed before the visual indication element is displayed, and in this case, referring to fig. 14, step 1302 may include:

step 1401: and the second host displays the visual reminding elements on the corresponding display screen.

Step 1402: the second host determines that the second end condition is satisfied, and proceeds to step 1302.

In step 1302, when the first visual indication element is displayed, it is generally required to use the position relationship information between the display screens, and if the position relationship information is set in each host shown in fig. 4, the second host may locally obtain the position relationship information from the second host in step 1302, so as to display the first visual indication element accordingly. If the position relation information between the display screens is set in one of the hosts, the first host can send the position information of the cursor to the host, the host calculates the relevant display information required by the first visual reminding elements displayed on each display screen in a centralized manner, such as the display positions, the indication directions and the graphic movement tracks of the first visual reminding elements, the relevant display information is sent to the corresponding second host, and the second host displays the first visual reminding elements on the corresponding display screens based on the display information.

For specific implementation of each step in the embodiments shown in fig. 13 and fig. 14, reference may be made to corresponding description in the foregoing embodiments, which is not repeated herein.

Different from the foregoing embodiment, if the hosts are required to relay and display the animation of the same second graphic moving from the preset pixel point of the first display screen to the cursor position on the corresponding display screen, each host moves the second graphic in the visual cue elements displayed by itself to the end point of the movement track in the corresponding display screen, and a display notification needs to be sent to the host with the next relay display to remind the next host to display the corresponding visual cue element. For example, if the display screen to which the cursor belongs is adjacent to the display screen corresponding to the second host, the method may further include:

judging that a second graph included by a first visual indication element displayed by a second host moves to the end point of the motion trail, sending a display notice to the first host, wherein the display notice is used for indicating the first host to display the second visual indication element on a display screen corresponding to the first host, and the second visual indication element comprises: and the second motion track is a second vector which is formed by taking a third intersection point as a starting point and taking the position of the cursor as an end point, the third intersection point is an intersection point of a third straight line and a side line of the display screen to which the cursor belongs, and the third straight line passes through a preset pixel point of the display screen corresponding to the second host and the position of the cursor.

The cursor prompting method shown in fig. 13 and 14 enables a user to quickly position a cursor position through a visual indication element under the system architecture shown in fig. 4, thereby improving user experience.

FIG. 15 is a flowchart of another embodiment of the cursor prompt method of the present application, which can be applied to a host computer under the system architecture shown in FIG. 2 or a host computer under the system architecture shown in FIG. 3; as shown in fig. 15, the method may include:

step 1501: the host detects a cursor finding operation.

If the host in this step is the host under the system architecture shown in fig. 2 or the host to which the cursor belongs under the system architecture shown in fig. 3, the host in this step may directly detect the cursor search operation based on the received mouse event or key event, and the specific implementation may refer to the corresponding description in step 601, which is not described herein again.

If the host in this step is a host other than the host to which the cursor belongs under the system architecture shown in fig. 3, the host to which the cursor belongs generally sends a notification of detecting the cursor searching operation to the host after detecting the cursor searching operation based on the received mouse event or key event, and the host in this step receives the notification and detects the cursor searching operation; thus, the step may comprise: the host receives a first notification sent by the host to which the cursor belongs, and the first notification is sent after the host to which the cursor belongs detects cursor searching operation.

Step 1502: the host computer determines a target display screen.

In a possible implementation manner, 1 display screen in the n display screens may be preset as a default display screen, and correspondingly, display screen information of the default display screen is preset in the host; at this time, step 1502 may include:

and acquiring preset display screen information, and taking the display screen indicated by the preset display screen information as the target display screen.

In another possible implementation, step 1502 may include:

the method comprises the following steps that a host acquires first images shot by cameras, and the cameras are arranged corresponding to a display screen;

the host selects a target display screen from the display screens according to the first image, wherein the target display screen is the display screen towards which the face of the user faces.

In order to capture the first image and determine whether the face of the user is directly facing the display screen in the subsequent step, a camera corresponding to each display screen may be disposed at a middle position above the display screen, as shown in fig. 16, a camera 1601 corresponding to the display screen 1602 is disposed at a middle position above the display screen 1602, and a camera 1603 corresponding to the display screen 1604 is disposed at a middle position above the display screen 1604.

If the host in this step is the host under the system architecture shown in fig. 2, the host is connected to each camera, and the host can directly acquire the first image shot by the camera from the camera;

if the host in this step is a host under the system architecture shown in fig. 3, and each host is correspondingly connected to one camera, this step may include: the method comprises the steps that a host computer obtains a first image shot by a camera from the corresponding camera; the method comprises the steps of obtaining first images shot by cameras corresponding to other hosts from other hosts except the host.

The selecting, by the host computer, a target display screen from the display screens according to the first image may include:

the host judges whether a first image with typical human face features exists in the image; having typical face features means that both eyes and mouth can be recognized from a target face of an image;

if the cursor does not exist, the host computer determines that the target display screen does not exist, and at the moment, the host computer can keep the position of the cursor unchanged or display the cursor at a preset position on one preset display screen.

If yes, judging the number of first images with typical human face features;

if the number is 1, determining the display screen corresponding to the first image with the typical human face characteristics as a target display screen;

and if the number is more than 1, selecting a first image from the first images with the typical human face characteristics, and taking a display screen corresponding to the selected image as a target display screen.

Selecting a first image from the first images with typical human face features may include:

for each first image with typical face features, drawing a triangle by taking the eyes and the mouth of a target face in the first image as vertexes, and calculating an angle difference value between internal angles in the triangle by taking the eyes as the vertexes; and determining the display screen corresponding to the first image with the minimum angle difference value as a target display screen.

The first image may include a plurality of faces, a target face may be selected from the plurality of faces, the target face may be input by a mouse operator in advance into the host, and the host performs corresponding storage; the host computer in this step may screen a target face from the plurality of faces in the first image for processing, for example, screen a target face 171 in fig. 17.

Referring to fig. 17, the left eye region 172, the right eye region 173, and the mouth region 174 of the target face may be identified according to a related image identification method, which is not described in detail in this embodiment of the present application. Further, a triangle A1B1C1 may be drawn with the center point A1 of the left eye region, the center point B1 of the right eye region, and the center point C1 of the mouth region as one vertex, respectively. Then, the difference between < C1A1B1 and < A1B1C1 can be calculated, the smaller the difference, the more the user faces the display screen corresponding to the image, the more likely the user will view the display screen, and therefore, the display screen corresponding to the first image with the smallest difference can be selected as the target display screen.

Step 1503: the host displays a cursor on the target display screen.

Wherein the display position of the cursor on the target display screen is not limited. The display position may be any point on the target display screen, preferably the center point.

Alternatively, in order to remind the user of noticing the cursor on the target display screen, a special display effect may be added to the cursor when the cursor is displayed, such as the size of the cursor being changed from large to small to normal, an aperture being displayed outside the cursor for a preset time period, and so on.

Wherein, if the host in this step is the host under the system architecture shown in fig. 2, the host can directly control the target display screen to display the cursor;

if the host in this step is the host under the system architecture shown in fig. 3, this step may include: the host judges that the target display screen is not the display screen corresponding to the host, and sends a cursor display instruction to the host corresponding to the target display screen, wherein the cursor display instruction is used for indicating the host corresponding to the target display screen to display a cursor on the target display screen; the host judges that the target display screen is the display screen corresponding to the host, and displays a cursor on the corresponding display screen.
