It should be noted that references to "one", "a plurality" and "a plurality" in this disclosure are intended to be illustrative rather than limiting, and those of ordinary skill in the art will appreciate that "one or more" is intended to be understood as "one or more" unless the context clearly indicates otherwise.
The names of messages or information displayed between the various devices in the embodiments of the present disclosure are for illustrative purposes only and are not intended to limit the scope of such messages or information.
Referring to fig. 1, a flow of one embodiment of a display method according to the present disclosure is shown. The display method as shown in fig. 1 comprises the following steps:
step 101, a focus position information set is acquired.
In the present embodiment, the execution subject (e.g., terminal device) of the display method may acquire the focus position information set.
Here, the focus position information in the focus position information set may indicate the position and the operation timing of a predefined operation on the shared screen. In other words, the user may make a predefined operation on the shared screen, which may be a continuous operation. The predefined operation may have a plurality of operation positions on the shared screen during the duration of the predefined operation. The time at which the user operates at each operation position may be the operation time corresponding to the operation position. In this disclosure, the location of the predefined operation may also be referred to as the focal position.
In some application scenarios, the screen interfaces presented at the transmitting end and the receiving end in a screen sharing manner may be referred to as a shared screen.
It can be understood that the execution body may be a transmitting end or a receiving end in the screen sharing scene. If the execution subject is a transmitting end, the execution subject locally acquires a focus position information set; if the executing body is a receiving end, the executing body may directly or indirectly receive the focus position information set from other electronic devices (e.g., a server or a transmitting end) to obtain the focus position information set.
The operation manner and function of the predefined operation may be set according to the actual situation, and are not limited herein. The predefined operation may be a prompt operation for prompting a viewing user to prompt a concentration of attention on the shared screen.
As an example, a portion of the "Tengwang order" may be displayed on the shared screen. The predefined operation may be directed to "eucrypti and arc Ji Fei" to alert individual users viewing the shared screen to the phrase "eucrypti and arc Ji Fei".
The specific implementation of the predefined operations is not limited herein.
As an example, the predefined operation may be a user operating a mouse to select a portion of the content in the shared screen.
It will be appreciated that during the predefined operation, the predefined operation may involve a plurality of operation positions (or sampling positions for the operation), some or all of which may be referred to as positions as focal positions, and each focal position may correspond to a respective focal time (i.e., an operation time).
Step 102, determining a target time point sequence associated with the current time instant, and performing the displaying step sequentially for each target time point in the target time point sequence.
In this embodiment, the execution subject may determine a target time point sequence associated with the current time, and execute the display step for each target time point in the target time point sequence in order.
In some application scenarios, the current time may be a current point in time that is constant over time. It will be appreciated that the determined set of focal position information may be varied as the current moment changes as the predefined operation continues.
Here, the target time point sequence associated with the current time point may be a sequence of several time points within a future time period from the current time point, and the several time points are arranged in the sequence in order of time.
Here, the number and the determination manner of the target time points are not limited here. Optionally, the target time point may be determined within a preset duration range from this moment; a preset number of target time points may also be determined.
As an example, the above-described execution body may determine one target time point every 5 milliseconds to determine at least one target time point in response to acquiring the focus position information set, and then will start from the moment (e.g., zero point).
In the present embodiment, the execution body may execute the display step for each target time point in the target time point sequence in order. Here, the order may refer to an order of the times indicated by the target time points.
In some application scenarios, performing the displaying step for each target point in time may transform the images displayed at each focus position of the shared screen.
Fig. 2 shows an implementation of the display step in this embodiment. Specifically, the displaying step of the present embodiment may include step 201 and step 202. The method comprises the following steps:
step 201, determining an image display style of an area including a position indicated by the focus position information in the shared screen area based on the target time point and the operation time in the focus position information.
Here, the focus position information may indicate a position, and an image display style of an area including the position may be determined based on the target time point and the operation timing in the focus position information. Thus, for each focus position information, the image display style corresponding to the focus position information can be determined.
Here, determining the image display style based on the target time point and the operation time point may be achieved in various ways. In some application scenarios, the interval between the operation time corresponding to the focus position information and the target time point may be determined as a time interval corresponding to the focus position information, and then, the image display style corresponding to each focus position information may be determined according to the time interval corresponding to each focus position information.
Here, the image display style may indicate a display mode of an image.
Here, the specific content of the image display style is not limited herein. As an example, the image display style may include, but is not limited to, at least one of: image size (number of pixels occupied), color of the image, image content.
At the target time point, the image of the determined image display style is added to the image display on the shared screen 202.
In this embodiment, the execution subject may add the image of the determined image display style to the shared screen for image display at the target time point.
Here, the presentation time of the single frame image may be taken as the target point in time. For a single frame image presented by the shared screen, an interval between a presentation time of the single frame image and an operation time corresponding to the focus position may be determined as a time interval corresponding to the focus position information. It will be appreciated that as time passes, the image frames presented by the shared screen are refreshed as well, successively reaching the target time point in the sequence of target time points. In the refreshing process of the image frames, the time intervals corresponding to the same focus position information are different for each image frame, and the different time intervals correspond to different image display patterns, so that the images displayed at the same focus position in each image frame are also transformed.
In other words, the time interval corresponding to the same focal position information is increasing with the passage of time. The time interval corresponding to the same focus position information is changed, so that the images displayed in different display steps of the focus position are different; thus, the shared screen displays different images at the same focus position during the display over time.
If the predefined operation is a continuous process, the set of focus position information may indicate a continuous predefined operation. As time goes by, in the course of the shared screen display, an image displayed at a focus position corresponding to a later operation may be an image displayed at a previous time at a focus position corresponding to a earlier operation. Thus, for a sustained predefined operation, as the operation proceeds, a process indicating that the image of the predefined operation is graded may be displayed on the shared screen.
It should be noted that, in the embodiment provided by the present disclosure, the focus position information set is acquired, then, the target time point sequence associated with the current time is determined, and the display step is performed at each target time point; the displaying step may include: for each focus position, determining an image display pattern based on the operation time and the target time point as time passes, and performing image display using the determined image display pattern; thus, during the execution of at least one display step over time, the shared screen displays different images at the same focus position during the display over time; the images are dynamically displayed at the respective focus positions, and as the operation proceeds, a process indicating that the image of the predefined operation is gradually changed may be displayed on the shared screen.
In some application scenarios, the step 201 may include: an interval between the operation time in the focus position information and the target time point is determined as a time interval corresponding to the determined focus position information; according to the time interval, an image display style of an area including the position indicated by the focus position information in the shared screen is determined.
In some application scenarios, a user may click on a laser pen control displayed on the shared screen, and then draw a line below a portion of the content of the shared screen using a virtual laser pen, which may be a predefined operation. In an application scene of a shared screen, a laser pen control is provided, so that the action of indicating the position by a user by using a laser pen in a real conference scene can be simulated.
In some application scenarios, after a user clicks a laser pen control, the user can simulate and control the laser pen on the shared screen through a mouse, for example, a simulated laser point can be displayed on the screen by pressing a mouse button, and the simulated laser point can be continuously displayed by pressing the mouse button; the simulated laser spot can also be moved during the process of holding the mouse button and moving.
In some application scenarios, after the user clicks the laser pen control, the simulated laser point may also move during the process of pressing the mouse button and moving. And, the process of pressing the mouse button and moving can be understood as the above-described predefined operation. The execution body can acquire a plurality of focus positions and corresponding operation moments of the mouse on the screen in the moving process. Then, a plurality of target time points are determined as time goes by, and a display step is performed for each target time point. Thus, during the movement of the mouse, the simulated laser spot does not appear as a real laser spot (the laser spot immediately disappears immediately before the real laser pen's focal position moves), but can remain for a period of time and change over time.
It should be noted that, the simulated laser pen provided in the prior art has the simulated laser points as the real laser points, and the laser points at the previous moment disappear immediately as soon as the focal position of the laser pen moves; in a poor network environment, the data transmission is not timely, so that the shared party cannot timely receive the focus position information to display the simulated laser points, and the display of the simulated laser points is interrupted; moreover, the propagation delay is usually accompanied by the concentrated reception of multiple data packets at the next time, which may cause the simulated laser spot to jump randomly at multiple focal positions. In contrast, the simulated laser pen implemented by the method provided by the disclosure can reduce the data transmission amount and the requirement on the instantaneity of data transmission, and can ensure uninterrupted display images of the simulated laser pen and improve the smoothness of display even in a poor network transmission environment (such as slower data transmission, blocking and the like).
In some embodiments, the smaller the time interval corresponding to the focal position information, the more pixels the image displayed in the area including the position indicated by the focal position information occupies. In other words, the smaller the time interval corresponding to the above-mentioned focus position information, the more pixels the image displayed in the vicinity of the focus position occupies.
Referring to fig. 3A, 3B and 3C, an application scenario of an embodiment of the present application is shown. Fig. 3A, 3B, and 3C may be different states of the display image for the prompt operation of the sentence "eucryptite and solitary Ji Fei" on the shared screen 301 over time. As an example, fig. 3A may be a display state at 10-point whole time;
in fig. 3A, a first display image 302 of the prompt operation is displayed under "eucryptite and solitary Ji Fei". Fig. 3B may be a display state at a time of 10 points 0 minutes 05 seconds; in fig. 3B, a second display image 302 of the prompt operation is displayed under "eucryptite and solitary Ji Fei". Fig. 3C may be a display state at a time of 10 points 0 minutes 10 seconds; in fig. 3C, a third display image 303 of the prompt operation is displayed under "eucryptite and solitary Ji Fei". From the first display image 301, the second display image 302, and the third display image 303, it can be seen that the display image presenting the operation is becoming shorter with the passage of time, and the image corresponding to the operation performed earlier is getting more and more informative.
As can be seen from the above examples, the display image of the simulated laser pen can be visually referred to as "comet" from a dynamic perspective. Thus, the simulated laser pen may be referred to as a "comet pen".
In some application scenarios, the comet pen may be continuous, or the comet pen may be discontinuous.
In some application scenarios, the specific implementation manner of the "comet pen" may be set according to actual situations, which is not limited herein.
In some application scenarios, the "comet pen style" may be implemented in the following manner: curve fitting can be carried out on the focus position indicated by the focus position information, and the fitted curve is used as an operation track; for a sampling point (which may include a focus) on the operation track, determining a first direction rendering pixel number along a perpendicular direction of a tangent line of the operation track, and a second direction rendering pixel number along the tangent line direction; rendering the pixel number in the first direction and the pixel number in the second direction as an image display style of the region including the position indicated by the focus position information; and at the target time point, adding the image of the determined image display pattern to the shared screen for image display, wherein the number of the rendering pixels in the second direction corresponding to the adjacent sampling points is overlapped in the rendering area on the shared screen.
In some embodiments, the "comet pen style" may be implemented in the following manner: the radius corresponding to the focus position information can be determined according to the time interval; determining a circle having a circle center at the position indicated by the focus position information and a radius corresponding to the circle center as an image display pattern of a region including the position indicated by the focus position information; and at the target time point, adding the image of the determined image display style to the shared screen for image display, wherein circles corresponding to adjacent focus position information are overlapped in a rendering area on the shared screen. In other words, on the shared screen, image rendering is performed with the focus position as the center and the corresponding radius as the radius, and then the image is added to the shared screen for image display.
In the above two modes of scene provision, the adjacent focus position information is overlapped between corresponding image display areas on the shared screen, wherein the image display areas are areas including positions indicated by the focus position information and displaying images. Thus, the continuity of the 'comet pen' image can be ensured.
In some embodiments, the determining, according to the time interval, the image display style of the region including the position indicated by the focal position information in the shared screen may include: focal position information with interval time being longer than a preset first time length threshold value is determined to be outdated focal position information; and determining the image display pattern corresponding to the outdated focus position information as not displaying the image pattern.
Here, the specific value of the preset first time length threshold may be set according to actual situations, which is not limited herein.
It should be noted that, as time goes by, the image corresponding to the predefined operation may gradually disappear. Therefore, in the process that the user explains the shared screen, on one hand, the explanation content can be timely prompted to each shared object, on the other hand, the image displayed based on the earlier predefined operation can be ensured, and the shared objects are not interfered.
In some embodiments, the step 101 may include: and acquiring a focus position information set, and deleting focus position information with interval time larger than a preset first time length threshold value from the focus position information set.
Before the displaying step, the focal position information whose interval time is longer than the preset first time threshold is deleted from the focal position set, so that the number of focal position information can be reduced, thereby reducing the amount of calculation for the focal position information.
In some embodiments, the determining, according to the time interval, the image display style of the region including the position indicated by the focal position information in the shared screen may include: and determining an image display style corresponding to each focus position according to the preset image gradual change corresponding relation information and the time interval corresponding to each focus position information.
Here, the above-described image gradation correspondence information is used to characterize the correspondence between the image display style and the time interval.
Here, the image gradation correspondence information may be implemented in various ways, and is not limited thereto. As an example, the image gradation correspondence table may be any one of the following but is not limited to: the functional relationship is, a correspondence table, or the like.
Here, by setting the image gradation correspondence information, an image display style corresponding to each time interval can be set for that time interval. Thus, after determining the time interval corresponding to the focal position information, the image display style corresponding to the time interval can be quickly determined.
In some embodiments, the user performing the predefined operation on the shared screen may include at least one user having the rights of the shared screen.
Here, the user performing a predefined operation on the shared screen may be one or more.
Here, the above-described shared screen authority may indicate that editing or graffiti can be performed on the shared screen.
Here, the focus position information set generated based on a predefined operation of the user corresponds to the user identification. In other words, the focus position information set generated by the predefined operation of the user is bound to the user identification of the user. Further, the predefined operations by the respective users may be displayed in different styles when the images are displayed based on the focus position information set.
In some embodiments, the above method further comprises: for a target point in time, executing a sharing flow, the sharing flow may include: and transmitting the data pair comprising the focus position and the corresponding image display pattern to the second terminal. Here, the second terminal may perform image display at the focus position of the shared screen according to the acquired data pair.
Here, the sharing flow may be performed for each target time point in the target time point sequence; the sharing flow may also be performed for a portion of the target time points in the sequence of target time points.
Here, at each target point in time, for each focus position in each display step, the execution subject determines a corresponding image display pattern for the focus position, whereby the focus position and the corresponding image display pattern can be packaged as a data pair. The sharing procedure may include: for each target point in time, a plurality of data pairs may be determined for the set of focus position information and sent to the second terminal. The second terminal may receive the data pairs transmitted based on the plurality of shared flows. The second terminal may display the same image as the execution subject described above at the focus position of the shared screen.
It should be noted that, the execution body determines the image display style and the sharing image display style, which can reduce the calculation amount of the second terminal and improve the consistency of displaying the sharing screen on different terminals. In contrast, if the execution subject transmits the focus position information and the corresponding focus time, the second terminal is required to calculate the image display pattern at each focus position, whereby, on the one hand, the calculation amount of the second terminal increases, and, on the other hand, there may be caused a difference in the image displayed on the shared screen of the second terminal and the above-described execution subject due to various reasons (delay, stuck, calculation inaccuracy) or the like.
In some embodiments, the method further comprises: acquiring a marked image drawn on a shared screen and a corresponding user identifier; and in response to the acquisition of at least two user identifications, distributing a preset display mode for each user identification, and displaying the mark image corresponding to the user identification by adopting the distributed display mode.
As an example, the marker images of different users may be displayed in different colors. By displaying the marking images of different users in different display modes, the user operation can be more intuitively distinguished.
In some embodiments, the above method may further comprise: and displaying the marked image and drawing user prompt information in a correlated way on a sharing screen. Here, the drawing user prompt information is used to prompt the user indicated by the user identification to draw the marker image.
Here, the user who draws on the shared screen may be a user who logs in to the execution subject, or may be a user who logs in to a terminal other than the execution subject. In other words, the drawing operation may be detected by the execution subject described above, the drawn marker image and the user identification for performing the drawing operation may be acquired; the other terminal may acquire the drawn marker image and the user identifier for the drawing operation, and the execution subject may acquire the marker image and the user identifier from the other terminal or the server. Here, the specific style of drawing the user prompt information may be set according to the actual situation, which is not limited herein. In some application scenarios, the drawing user prompt information includes at least one of: user identification, text for prompt and preset display style for user identification.
Here, the executing subject performs the association display of the obtained marker image and the prompt information of the drawing user, so that the user can know the drawing person of the marker image when seeing the colleague of the marker image; thus, in this scene involving multiple persons sharing a screen, explicit renderer information can be provided for each marker image.
In some embodiments, the above method further comprises: determining a target stop time point in response to determining that the drawing is completed; and stopping displaying the drawn user prompt information in response to the fact that the current time point is determined to be the target stop time point.
Here, the interval between the above-described target stop time point and the time point when drawing is completed is a preset second duration.
Here, if the execution subject detects the drawing operation as described above, the drawing completion may be directly determined by the execution subject as described above. If the electronic device other than the execution subject detects a drawing operation, a drawing completion instruction signal may be sent to the execution subject by the electronic device, and then the execution subject may determine that drawing is completed in response to receiving the drawing completion instruction signal.
Here, how to determine that drawing is completed by detecting a drawing operation may be set according to actual conditions, and is not limited herein. As an example, the drawing operation may be performed by the user holding the mouse, and when it is detected that the user stops holding the mouse, it may be determined that the drawing is completed.
Here, the specific value of the preset second duration may be set according to the actual situation, which is not limited herein.
It should be noted that, if the current time point is the target stop time point, the displaying of the drawing user prompt information may be stopped, so that the drawing user prompt information may be displayed in a period of time during and after the drawing, the drawing user prompt information may be displayed, and during and after the drawing, the time period in which the watching user of the shared screen pays attention to the marked image may be put on a new event, after the time period has elapsed, the watching user of the shared screen may be stopped from displaying during the time period, so that the watching user may be guaranteed to learn the information; and the information quantity on the screen can be reduced by stopping displaying the information, so that the interference information on the shared screen can be reduced.
As an example, referring to fig. 4A and 4B, fig. 4A and 4B illustrate an implementation of drawing user prompt information. In fig. 4A and fig. 4B, the shared screen 401 may show a part of the content of "Tengwang Gein", the user "king" may be marked for the sentence "cloud pin rain, color-clear", in fig. 4A, the marked image 402 is displayed below the sentence "cloud pin rain, color-clear", and the drawn user prompt information 403 is displayed in association with the marked image 402 for prompting that the marked image 402 is drawn by "king". In fig. 4B, a schematic diagram of the current time point being the target stop time point and showing the drawing of the user prompt information is shown.
In some embodiments, the above method may further comprise: acquiring a mark image drawn on a shared screen; the acquired marker image is subjected to smoothing processing to generate an adjusted image.
Here, the above smoothing process may improve the smoothness of the lines of the mark image, so that the mark image as a whole has higher smoothness without the occurrence of sharp points or jaggies.
As an example, smoothing may be performed on a straight line or a curved line.
It is to be understood that, by the smoothing processing, the generated image has higher smoothness, and the adjusted image can be indicated by a smaller amount of data. By smoothing the marker image, the data amount can be compressed. Thus, the data transmission amount can be reduced in the screen sharing process.
