Detailed Description
In order that the above objects, features and advantages of the present invention can be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings. It should be noted that the embodiments of the present invention and features of the embodiments may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.
FIG. 1 is a flow chart illustrating a method for intelligently magnifying a shared desktop according to the present invention.
As shown in fig. 1, a first aspect of the present invention provides a method for intelligently magnifying a shared desktop, including the following steps:
s102, receiving desktop content and hotspot application program window coordinates shared by a client from a speaker, and storing the desktop content and the hotspot application program window coordinates by a local side, wherein the desktop content comprises part or all of the hotspot application program window content;
s104, pushing the shared desktop content to a display area data module;
s106, the display area data module determines whether a shared desktop display interface at the local side needs to be refreshed according to the shared desktop content;
s108, receiving a screen trigger event on a shared desktop display interface of the local side, judging whether the screen trigger event triggers a screen amplification request, and if so, sending the coordinate position of a trigger point to an area amplification calculation engine;
s110, acquiring shared desktop contents and hotspot application program window coordinates from data stored by the local side by the area amplification calculation engine, and calculating according to a preset calculation rule to obtain an amplification area;
s112, the amplification area is pushed to the display area data module, and the display area data module refreshes the shared desktop display interface based on the amplification area.
It should be noted that before the above steps are performed, a network conference system needs to be set up, where the network conference system may include a speaker client, a conference server, and at least one participant client, the speaker client is held by a speaker, the participant clients are held by corresponding participants, and the speaker client and the participant clients may be downloaded from a platform by the speaker and the participants respectively and installed on the communication device. Preferably, the communication device may be a mobile phone, a PC, an IPAD, a smart watch, etc., but is not limited thereto. The speaker client and the at least one participant client are in network communication with the conference server respectively. Firstly, a speaker client shares a desktop, and sends shared desktop content and hotspot application program window coordinates to a conference server, the conference server receives the shared desktop content and the hotspot application program window coordinates and then respectively sends the shared desktop content and the hotspot application program window coordinates to a participant client, and the participant client receives the shared desktop content and the hotspot application program window coordinates and displays the desktop content.
It should be noted that the desktop content shared by the speaker is actually a picture, the hot application window is a partial area content in the picture, and the area range of the hot application window can be determined by the coordinates of the hot application window. Therefore, the client of the participant can automatically lock the area range of the hotspot application program window after receiving the hotspot application program window coordinates. It is to be appreciated that the hotspot application window coordinates are coordinate data relative to the desktop content picture that conforms to the (x, y, width, height) format.
It is to be understood that the shared desktop display interface may also be referred to as a shared desktop display window or a shared desktop display screen.
According to the embodiment of the present invention, determining whether the screen trigger event triggers a screen amplification request specifically includes:
traversing a screen action template database prestored at the side terminal based on the trigger action of the screen trigger event, wherein the screen action template database comprises a zooming-in screen action template, a zooming-out screen action template and a moving screen action template;
and if the trigger action conforms to the amplified screen action template, triggering to generate an amplified screen request and feeding the amplified screen request back to the regional amplification calculation engine.
It should be noted that, in this embodiment, the predetermined action template of the enlarged screen is a certain coordinate position of a double-click screen, and when the trigger action captured by the user is a certain coordinate position of a double-click or a continuous triple-click screen, the trigger action is considered to conform to the action template of the enlarged screen, and then the request for generating the enlarged screen is triggered. In this embodiment, the preset reduced screen action template is a screen on which two fingers slide relatively, when the trigger action of the user is captured and conforms to the reduced screen action template, a reduced screen request is generated by triggering, and then a region reduction calculation engine calculates a reduction ratio and a reduced region, and displays the display region data module based on the reduced desktop content. In this embodiment, the predetermined mobile screen action template is a single finger sliding on the screen, and when the trigger action captured by the user conforms to the mobile screen action template, the trigger action generates a mobile screen request, and then the area mobile computing engine calculates the mobile direction and the mobile distance, and displays the display area data module based on the moved desktop content.
According to the embodiment of the invention, traversing the screen action template database prestored at the local side based on the trigger action of the screen trigger event specifically comprises the following steps:
retrieving a screen action template from said screen action template database;
comparing the trigger action with the screen action template, and calculating the similarity of the trigger action and the screen action template;
if the similarity is greater than or equal to a preset threshold value, generating a corresponding screen operation request based on the screen action template; if the similarity is smaller than the preset threshold, continuously taking out the next screen action template from the screen action template database for comparison until the screen action template with the similarity larger than or equal to the preset threshold is found;
and if the screen action template with the similarity larger than or equal to the preset threshold is not found by traversing the screen action template database, the screen operation request is not triggered.
It should be noted that the screen action template may be a zoom-in screen action template, a zoom-out screen action template or a mobile screen action template; the screen operation request is a screen enlarging request, a screen reducing request or a screen moving request. It will be appreciated that the operation of the user on the screen may not be canonical and may not fully conform to the screen action template, such as: the action template of the amplified screen is a certain coordinate position of the double-click screen, but a user may continuously click the certain coordinate position of the screen three times, and at the moment, the similarity between the certain coordinate position of the continuously three-click screen and the certain coordinate position of the double-click screen can be calculated to be more than or equal to a preset threshold value, so that the request for generating the amplified screen can be triggered. For another example: the mobile screen action template is formed by sliding a single finger on the screen, but the user may slide on the screen synchronously by using two fingers or three fingers, and at this time, the similarity between the action of sliding the two fingers or three fingers on the screen synchronously and the action of sliding the single finger on the screen can be calculated to be greater than or equal to a preset threshold, so that the generation of the mobile screen request can be triggered.
According to the embodiment of the invention, the calculation of the amplification region according to the preset calculation rule specifically comprises the following steps:
judging whether all areas of the hot application program window are in the shared desktop display interface or not;
if not, executing a normal amplification display process by taking the coordinate position of the trigger point as a center, and if so, judging whether the hotspot application program window is amplified in a full screen mode;
if yes, executing a normal amplification display process by taking the coordinate position of the trigger point as a center, and if not, amplifying the hot spot application program window on the shared desktop display interface in a full screen mode.
It should be noted that whether all areas of the hotspot application window are within the shared desktop display interface may be determined by calculating whether the hotspot application window coordinates fall within the shared desktop display interface. It will be appreciated that if not, a normal zoom-in display procedure is performed centered around the trigger point coordinate location, and the zoomed-in desktop content centers the trigger point coordinate location on the shared desktop display interface. If the current position of the trigger point coordinate is within the hot spot application window, the hot spot application window is enlarged on the shared desktop display interface in a full screen mode.
According to an embodiment of the present invention, the executing of the normal zoom-in display process with the trigger point coordinate position as a center specifically includes:
calculating an amplification area by an area amplification calculation engine by taking the coordinate position of the trigger point as a center according to a preset amplification ratio;
and transmitting the amplification area to a display area data module, and refreshing the shared desktop display interface by the display area data module based on the amplification area.
It should be noted that, for a preset magnification ratio, the multiple magnification screen requests correspond to one magnification screen request, and the multiple magnification screen requests correspond to multiple times of the preset magnification ratio. Preferably, the predetermined magnification ratio is 2:1, but is not limited thereto.
According to the embodiment of the present invention, enlarging the hot spot application window on the shared desktop display interface in a full screen includes:
presetting the sharing desktop display interface to be a rectangle, and acquiring the transverse size and the longitudinal size of the rectangular sharing desktop display interface;
calculating the aspect ratio A of the shared desktop display interface according to the transverse size and the longitudinal size, wherein A = transverse size/longitudinal size;
acquiring the transverse boundary size and the longitudinal boundary size of a hotspot application program window according to the hotspot application program window coordinate;
calculating the aspect ratio B of the hot spot application window according to the transverse boundary size and the longitudinal boundary size, wherein B = transverse boundary size/longitudinal boundary size;
comparing the sizes of the A and the B, if the A is smaller than the B, enabling the hot application program window to occupy a rectangular shared desktop display interface along the transverse direction, and enabling the hot application program window to be centered on the shared desktop display interface in the longitudinal direction; if A is larger than B, the hot spot application program window occupies a rectangular shared desktop display interface along the longitudinal direction, and the hot spot application program window is horizontally centered on the shared desktop display interface; if A is equal to B, the hotspot application window occupies the rectangular shared desktop display interface along both the horizontal direction and the vertical direction.
It should be noted that, the application program window occupies the rectangular shared desktop display interface along the horizontal direction, and two boundaries of the application program window along the horizontal direction are overlapped with two boundaries of the rectangular shared desktop display interface along the horizontal direction. Similarly, the application program window occupies the rectangular shared desktop display interface along the longitudinal direction, and two longitudinal boundaries of the application program window are overlapped with two longitudinal boundaries of the rectangular shared desktop display interface.
Preferably, the application window may be rectangular, triangular, circular, but is not limited thereto.
It can be understood that, since the aspect ratio of the application program window is different from that of the shared desktop display interface, the application program window is displayed on the shared desktop display interface according to a better full-screen display mode by comparing the aspect ratio of the application program window and the shared desktop display interface, and the display effect of the shared desktop is further optimized.
According to an embodiment of the present invention, prior to receiving the shared desktop content and hotspot application window coordinates from the presenter client, the method further comprises:
selecting a hotspot application program window from the shared desktop content by the speaker client based on a predetermined hotspot rule;
and the speaker client acquires the hot application program window coordinates, sends the hot application program window coordinates and the shared desktop contents to the conference server, and forwards the hot application program window coordinates and the shared desktop contents to the corresponding participant client by the conference server.
According to an embodiment of the present invention, the predetermined hotspot rule is:
calculating the proportion of the area of an application program window to the shared desktop area of the client of the speaker;
and judging whether the proportion is larger than or equal to a preset proportion threshold value, if so, setting the application program window as a hot spot application program window, and if not, setting the application program window without a hot spot in a shared desktop of the speaker client, wherein the hot spot application program window coordinate does not need to be fed back to the participant client.
Preferably, the preset ratio threshold may be 70%, but is not limited thereto.
According to an embodiment of the present invention, the predetermined hotspot rule may also be:
if the shared desktop of the speaker client side is provided with a plurality of application program windows, calculating the proportion value of the area of each application program window in the shared desktop area of the speaker client side respectively;
and comparing the scale values, setting one application program window with the largest scale value as a hotspot application program window, and if the scale value is two application program windows with the largest scale value, giving no hotspot application program window in a shared desktop of the speaker client, and feeding back the hotspot application program window coordinates to the participant client.
It can be understood that the hotspot application program window can also be manually set by the speaker, and the manually set permission is greater than the permission set by the hotspot rule. In other words, the system defaults to setting the first application window according to the hotspot rule, and if the speaker manually sets the second application window again as the hotspot application window at this time, the system cancels the first application window as the hotspot application window, mostly uses the second application window as the hotspot application window, and sends the coordinates of the second application window to the participant client.
According to an embodiment of the present invention, after the display area data module refreshes the shared desktop display interface based on the enlarged area, the method further comprises:
when the shared desktop display interface displays the amplified area, if the desktop change content newly shared by the client of the speaker is received, the shared desktop display interface keeps displaying the amplified area;
carrying out local side temporary storage on the newly shared desktop change content, and prompting an icon of the newly shared desktop change content to a state column preset in the shared desktop display interface;
and if the icon is clicked, the shared desktop display interface switches and displays the newly shared desktop change content from the display amplification area.
It should be noted that, when the shared desktop display interface is displaying the enlarged area, it indicates that the participant is watching the enlarged area at this time, and if newly shared desktop change content is received at this time, the new desktop change content cannot be immediately replaced based on the newly shared desktop change content, so as to avoid affecting the experience of the participant. The shared desktop display interface can execute the switching action only after receiving the active replacement instruction of the participant. After switching, the originally shared desktop content and the hotspot application window coordinates are deleted from the database of the local side so as to make sufficient space for other subsequent data.
To further illustrate the technical solution of the present invention, fig. 2 shows an interaction diagram of the network conference system of the present invention.
As shown in fig. 2, the speaker shares the desktop and sends it to the server (i.e., the conference server), the server forwards the shared desktop to the mobile end of the participant, the participant watches the shared desktop of the speaker at the mobile end, the participant triggers an action such as double-click on the screen at the mobile end, and if the action falls into a hot application window (e.g., the application window identified as a in fig. 2) according to the calculation rule of the area enlargement calculation engine, the hot application window will automatically enlarge in equal proportion and fill the screen at the mobile end.
