The following examples are described in detail.
Example one
Fig. 1 is a flowchart of a page operation method of an intelligent interactive tablet according to an embodiment of the present invention. The page operation method of the smart interactive tablet provided in the embodiment may be executed by an operation device of the smart interactive tablet, the operation device of the smart interactive tablet may be implemented in a software and/or hardware manner, and the operation device of the smart interactive tablet may be formed by two or more physical entities or may be formed by one physical entity. For example, the operating device of the smart interactive tablet may be a cell phone, an industrial control computer, or the like.
For easy understanding, in the embodiment, the intelligent interactive tablet is taken as an actual carrier, and a detailed process of adjusting target selection, association and adjusting response when the page operation method of the intelligent interactive tablet is implemented is exemplarily described. The intelligent interactive panel can be an integrated device which controls the content displayed on the display panel and realizes man-machine interaction operation through a touch technology, and integrates one or more functions of a projector, an electronic whiteboard, a curtain, a sound box, a television, a video conference terminal and the like.
Generally, as shown in fig. 2, the smart interactive tablet 1 includes at least one display screen. For example, the smart interactive tablet 1 is configured with a display screen with touch function, and the display screen may be a capacitive screen, a resistive screen or an electromagnetic screen. In this embodiment, an intelligent interactive tablet is provided, and further, a user may implement a touch operation by touching a display screen with a finger or a stylus, and accordingly, the intelligent interactive tablet detects a touch position and responds according to the touch position to implement a touch function. Typically, the smart interactive tablet is installed with at least one operating system, wherein the operating system includes, but is not limited to, an android system, a Linux system, and a Windows system. Further, the smart interactive tablet may install at least one application having a writing function. The application program may be an application program carried by an operating system, and an application program downloaded from a third-party device or a server is also installed. Optionally, the application program has other editing functions besides the writing function, such as inserting tables, inserting pictures, inserting graphics, drawing tables, drawing graphics, and the like. And the drawn table or graph is a standard element drawn by the computer. Computer drawn standard elements may be understood as print standard elements drawn by an intelligent interactive tablet, which are distinguished from elements written by a user.
A touch screen configured by intelligent handwriting equipment such as an electronic whiteboard, an electronic blackboard, a digitizer, an intelligent conference tablet and the like is provided with a writing area for responding to the writing operation of a user to display input content, when writing is performed in the writing area, for example, a touch pen or a finger is used to touch the touch screen, the touch screen can sense the change of current, the change of voltage or the change of magnetic flux (corresponding to the specific setting type of the capacitive touch screen, the resistive touch screen or the electromagnetic touch screen), so as to obtain a touch signal containing the coordinates of the touch position and the trigger time of the touch signal, according to the coordinates of the touch position and the trigger time of the touch signal, track data of a writing track input in the process of writing to lifting and stopping writing by a stylus or a finger of a user can be obtained, and the writing track input by the user is displayed in a writing area of the touch screen in real time according to the track data. Of course, the writing process is not limited to writing, and any entry process implemented on the touch screen of the intelligent handwriting device for displaying the operation track can be regarded as the writing process. In addition, the touch operation may respond to operations such as clicking, dragging, and the like of the user according to the difference of the display element of the occurrence position of the touch operation. The way in which these different responses are processed at the bottom level is the same. Generally, the area where the touch writing occurs coincides with the area where the display is located, i.e., the display area 2 shown in fig. 2. Based on the hardware realization of basic functions such as touch and display, the function of whiteboard application can be further realized on the intelligent interactive flat plate, and each embodiment of the scheme is the scheme realization of the whiteboard application.
Specifically, referring to fig. 1, the page operation method of the intelligent interactive tablet specifically includes:
and step S101, receiving element selection operation in the currently displayed whiteboard page of the whiteboard application interface.
The application interface refers to an interactive interface used for receiving and/or displaying information, such as an application of a video playing class, and the interactive interface is mainly used for displaying a changed video picture; the real-time communication type application, wherein the interactive interface is mainly used for receiving the content input by a near-end user and displaying the content input by a far-end user; the interactive interface of the file editing application is mainly used for receiving and displaying the content input by the user; the interactive interface of the browser-type application is mainly used for receiving keywords input by a user and displaying webpage content obtained based on the keywords.
In this embodiment, the application interface specifically targeted refers to a user interface presented in the whiteboard application use process, that is, a whiteboard application interface. As described above, the whiteboard application refers to an application for a user to perform operations such as writing and displaying, and may be used to generate writing traces according to a writing track of the user on the whiteboard application interface, and may also be used to insert other multimedia elements such as graphics, pictures, forms, and the like on the whiteboard application interface. In the whiteboard application interface, a user can realize writing, drawing, erasing and other operations similar to those of an entity blackboard, and further has better digital functions of moving, storing, zooming, inserting pictures, adjusting colors, setting stroke weights and the like. Writing-based operations in whiteboard applications are a mature realization of the prior art and are not described in detail in this solution. In practical applications, the whiteboard application may also be named as a writing application, an electronic whiteboard application, a collaborative whiteboard application, and the like, and the application for realizing the above functions is equivalent to the whiteboard application of the present application regardless of changes in the name.
During the use of the whiteboard application, the whiteboard application is usually displayed in a full screen, that is, the whiteboard application fills up the display area 2 of the intelligent interactive tablet 1 in fig. 2, and for clarity, only the display change of the display area 2 is illustrated in the following figures. In addition to the contents written and added during the use process and the contents inserted into the display (for example, a cross is shown in fig. 3), the contents displayed in the whiteboard application interface 20 also have various tool controls for operating the above contents, and these tool controls are normally displayed in the toolbar 21 in the whiteboard application interface 20, and in the example description of the present scheme, the toolbar 21 is displayed at the bottom of the whiteboard application interface 20, and may also be displayed on the left and/or right side in the actual layout, or even displayed on the left, right, and bottom in a comprehensive manner. Some tool controls in the toolbar 21 correspond to digital implementation of the function of the entity blackboard, such as writing, erasing, turning pages (part of the entity blackboard is available), and other tool controls are function supplement controls implemented on the basis of the whiteboard application, such as cancel input, restore input, handwriting selection, insertion, and the like.
Whiteboard elements are various display content generated at the whiteboard application interface during use of the whiteboard application, such as handwriting, inserted pictures, inserted forms, document presentation windows, etc., such as the crosses shown in fig. 3. The whiteboard elements are used as editable objects, and the basic operation of realizing the established editing target is to select at least one whiteboard element as an operation target, namely an element selection operation. The intelligent interactive panel is used as touch equipment, and the selected whiteboard elements can be realized through given touch operations, such as clicking, long pressing, circle selection and the like; in addition, because the intelligent interactive tablet can be connected with external input equipment such as a mouse and a keyboard, the operation of selecting the whiteboard element can also be realized through other external equipment such as a mouse and a track ball.
In the process of using the whiteboard application, in order to better organize and present interactive contents, for example, in a meeting process, different topics are usually added to different whiteboard pages, and for some contents needing to be repeatedly presented in multiple topics, the contents can be directly added from one whiteboard page to another whiteboard page, so that the rapid movement of specific information is realized.
And step S102, responding to the element selection operation, and displaying an element editing menu.
For a certain selected whiteboard element, the whiteboard application (or the terminal device) cannot predict what editing operation needs to be performed on the currently selected whiteboard element, and at this time, only all editing operations that may occur to the selected whiteboard element can be presented in an element editing menu manner, so as to further determine the next specific editing operation according to the operation of the user. The element editing menu may specifically include deletion, format adjustment, rotation, scaling, and the like, and may display, in the element editing menu, editing operations that may be used by the whiteboard element of the type according to the type of the whiteboard element, but not display editing operations that may not be used by the whiteboard element of the type, for example, editing operations for font adjustment are not displayed for the whiteboard element of the photo class. In the scheme, the element editing operation across pages is aimed at, so that the element editing menu comprises a cross-page editing option, namely, the operation on the target whiteboard element is related to at least two whiteboard pages.
Step S103: and responding to the menu trigger operation of the cross-page editing option, and displaying preview windows of all the whiteboard pages.
For whiteboard elements, one of the two whiteboard pages edited across pages is the whiteboard page where the whiteboard page is located by default, and the other whiteboard page needs to be confirmed according to user operation. In the scheme, under the condition that one whiteboard page is defaulted, if a cross-page editing option is triggered, namely a menu triggering operation is detected in an area where a menu item corresponding to the cross-page editing in an element editing menu is located, it is confirmed that the other whiteboard page needs to be confirmed currently, at this time, all whiteboard pages are presented in a preview window mode, and a user selects to select the whiteboard page and simultaneously means to send an instruction of adding a whiteboard element in the selected whiteboard page. The thumbnail of the whiteboard page is displayed in the preview window, so that a user can quickly confirm the whiteboard page needing to be added with the target whiteboard element according to the thumbnail, page-by-page turning and whiteboard page browsing are avoided, and the operation efficiency is improved. The thumbnail can be obtained by screenshot and displaying the whiteboard file in the background according to pages, the specific screenshot can be the screenshot of the whole page or the screenshot of the content in the current display range, then the screenshot content is displayed in sequence according to the sequence of the whiteboard pages, and the association relationship between the screenshot and the corresponding whiteboard pages is established.
Step S104: and responding to the page selection operation detected in the preview window, switching the whiteboard page corresponding to the page selection operation into a current display state, and adding the target whiteboard element to the currently displayed whiteboard page.
Through the association relationship between each preview image in the preview window and the whiteboard page, the page selection operation can directly point to the corresponding whiteboard page through the page screenshot in the preview window, so that the whiteboard page corresponding to the page selection operation is switched to the current display state, and the target whiteboard element selected in step S101 is added to the currently displayed whiteboard page.
Receiving an element selection operation occurring in a whiteboard page currently displayed on a whiteboard application interface, where the whiteboard page displays whiteboard elements, and the element selection operation is used to select at least one target whiteboard element from the whiteboard elements; in response to the element selection operation, displaying an element editing menu, the element editing menu including cross-page editing options; responding to the menu trigger operation of the cross-page editing option, and displaying preview windows of all whiteboard pages; and responding to the page selection operation detected in the preview window, switching the whiteboard page corresponding to the page selection operation into a current display state, and adding the target whiteboard element to the currently displayed whiteboard page. The whiteboard elements in one whiteboard page are quickly added to the other whiteboard page through twice menu bar operations, so that the complex operation process of page adjustment when the whiteboard elements are quickly adjusted to display is avoided, the convenience of operation is improved, and the user interaction is more friendly.
Example two
Fig. 4 is a flowchart of a page operation method of an intelligent interactive tablet according to a second embodiment of the present invention. The present embodiment is embodied on the basis of the above-described embodiments.
Specifically, referring to fig. 4, the page operation method of the intelligent interactive tablet provided in this embodiment specifically includes:
step S201, when a closed track generated by touch is detected in a whiteboard page currently displayed on the whiteboard application page, confirming that an element selection operation is received.
The touch operation on the whiteboard application page may be to input whiteboard elements in the current whiteboard page, or may be to select some whiteboard elements. In order to avoid the misoperation and the error input, in the present solution, the closed track may be further detected after triggering the control selected by the handwriting in the toolbar 21, and then the element selection operation is confirmed to be received. The closed track may be a completely closed track, or may be an opening track with a minimum width of an opening within a set width threshold, so that a user can select a target whiteboard element when the operation is not particularly accurate, and at this time, the associated whiteboard element in the closed track is the target whiteboard element. The associated whiteboard elements in the closed track may refer to whiteboard elements completely in the closed track, or may refer to whiteboard elements that intersect with the closed track and the internal area thereof, which is not specifically limited in this scheme. Referring to fig. 5, on the basis of fig. 3, the selection of whiteboard elements (cross-shaped patterns) is completed by closing tracks.
Besides, the element selection operation is confirmed through the closed track, when the single-point touch is detected in the currently displayed whiteboard page of the whiteboard application page, the element selection operation is confirmed to be received, and the topmost whiteboard element at the position of the single-point touch is the target whiteboard element.
And step S202, responding to the element selection operation, and displaying an element editing menu.
The operation of adding whiteboard elements is generally two types, namely copying and moving (or cutting and pasting), that is, in the element editing menu, the cross-page editing options generally comprise a moving option and a copying option.
One specific implementation is that the move option and the copy option are integrally displayed in the same menu option in the element editing menu. And further confirming the operation content in the follow-up process. For example, fig. 6 is based on fig. 5, after the whiteboard element is selected, the copying and moving are integrated in the element editing menu and displayed on the same menu option, and the menu option is triggered to indicate that the copying or moving is needed subsequently.
And step S203, responding to the menu trigger operation of the cross-page editing option, and displaying preview windows of all whiteboard pages.
The preview window may be selected for display adjacent to the target whiteboard element, for example from below or to the right, and arranged in another row when a row is full and up when the bottom is full, so that all whiteboard pages are displayed in as complete an order as possible.
Assuming that there are 3 whiteboard pages currently, a pentagram, a hexagon, and a cross are sequentially and respectively displayed and recorded, and after the menu in fig. 6 is triggered, as shown in fig. 7, 3 whiteboard pages are respectively subjected to screenshot preview.
Step S204, in response to the page selection operation detected in the preview window, switching the whiteboard application page corresponding to the page selection operation to a current display state, and displaying operation controls of the moving operation and the copying operation on the currently displayed whiteboard page.
The method is suitable for the integrated display of the moving operation and the copying operation, and particularly needs to further confirm which one of the moving operation and the copying operation is selected on the selected whiteboard page, wherein the further confirmation of the operation is realized through operation controls of the moving operation and the copying operation. In the interface shown in FIG. 7, the first whiteboard page is validated, and in response to this selection, as shown in FIG. 8, it is now necessary to place it in the current display and further provide controls for the user to confirm that it is a copy or move.
And step S205, in response to the confirmation operation detected by the operation control, copying or moving the target whiteboard element to the currently displayed whiteboard page.
And if the confirmation operation is detected in the operation control corresponding to the copying operation, copying the target whiteboard element to the currently displayed whiteboard page, namely displaying the whiteboard element in both the two related whiteboard pages. And if the operation control corresponding to the moving operation detects the confirmation operation, moving the target whiteboard element to the currently displayed whiteboard page, namely, the whiteboard page where the target whiteboard element is located before does not continue to display the whiteboard element, and displaying the whiteboard element only in the whiteboard page confirmed by the page selection operation.
The element editing menu is different from the element editing menu in that the mobile option and the copy option are integrally displayed in the same menu option, the mobile option and the copy option can be respectively displayed in different menu options, and at the moment, the display change of the whiteboard element is directly carried out according to the selection of the menu option and the selection of the whiteboard page. I.e., directly move or copy the target whiteboard element to the selected whiteboard page.
In a specific moving or copying process, the display proportions of two whiteboard pages associated with the target whiteboard element and the initial size and initial display position of the target whiteboard element need to be acquired, and the display size and display position of the currently displayed whiteboard page of the target whiteboard element are confirmed according to the display proportions and the initial display position and are correspondingly displayed. Specifically, when the cross-page editing operation of the whiteboard element is confirmed to be received, the position and the zoom ratio of the element on the original whiteboard page are recorded, then the target whiteboard page is jumped to, the whiteboard element is placed on the target whiteboard page after the jump, the placement position is the zoom ratio of the original whiteboard page divided by the coordinate of the original whiteboard page and then multiplied by the target whiteboard page, and the size of the whiteboard element is the zoom ratio of the original whiteboard page divided by the zoom ratio of the original whiteboard page and then multiplied by the target whiteboard page. The whiteboard page after the selected cross has moved to the whiteboard page with the five-pointed star is shown in fig. 9.
In the process of confirming the specific target whiteboard page, besides selecting a screenshot of an existing whiteboard page from a preview window, a blank whiteboard page can be newly built, specifically, in the preview window, besides previewing the existing whiteboard page, a blank page adding control is also provided, when the blank page adding control is triggered, blank page adding is realized, an icon corresponding to the blank page adding control can be identified through a plus sign to show a blank page adding function which can be realized when the control is triggered, in addition, a thumbnail of the blank page can be set for the identification to serve as a background, and a better operation guiding effect is achieved. For the added blank page, its page number order may be displayed on the blank page, for example 12/12 indicates that there are 12 white board pages in total after the addition of the blank page, and the newly added blank page is page 12.
In a specific adding process, the page sequence of the blank whiteboard page and the existing whiteboard page can be confirmed according to the triggering position of the blank page adding control. The blank page adding control is displayed at the last of the whiteboard pages, partial areas of page preview borders corresponding to the front whiteboard pages and the adjacent two whiteboard pages of the whiteboard pages can be set as the blank page adding control, and when the blank page adding control is triggered, the blank page is inserted into the corresponding position according to the specific triggering position. For example, if the adding control of the front or the last blank page is triggered, the blank page is inserted at the front or the last; for another example, if a blank page adding control between the 2 nd page and the 3 rd page of the whiteboard page is triggered, a blank page is inserted between the 2 nd page and the 3 rd page of the whiteboard page, that is, the newly inserted blank page is taken as the 3 rd page, and the original 3 rd page is continued to be the 4 th page.
In terms of implementation, in response to the page selection operation detected in the preview window, the method switches the whiteboard page corresponding to the page selection operation to the current display state, and adds the target whiteboard element to the currently displayed whiteboard page, including:
and responding to the page selection operation detected by the blank page adding control, adding and displaying a blank whiteboard page, and adding the target whiteboard element to the blank whiteboard page.
The process of adding the whiteboard elements in the blank whiteboard page is the same as the process of adding the normal whiteboard page, and a repeated description is not given here. Through the scheme, the page can be newly built and white board elements can be added quickly when specific requirements exist. For example, when a second dimension discussion needs to be performed on a question during a meeting, a whiteboard element related to the question may be directly added to a blank whiteboard page for subsequent meeting discussion.
When the whiteboard pages are previewed, responding to the menu triggering operation of the cross-page editing options, and displaying the preview windows of all the whiteboard pages according to the adding sequence, so that the sequential previewing is realized, and a user can conveniently confirm the adding positions of the whiteboard elements.
The whiteboard application may limit the upper limit of a whiteboard page, that is, the number of pages of a whiteboard file cannot be increased infinitely, so that when a preview window displays, if the total number of whiteboard pages is smaller than the preset upper limit of pages, a blank page adding control is displayed on the preview window, and if the total number of whiteboard pages is equal to the preset upper limit of pages, the blank page adding control is not displayed, so that useless operation of a user is avoided.
Further, the target whiteboard element is placed at a level above the level of all existing elements in the new whiteboard page. If multiple elements are moved/copied, the internal hierarchy of the multiple elements is kept unchanged, and the internal hierarchy of the multiple elements is kept the same as the original whiteboard page. If the placement of the new whiteboard page contains other elements (such as pictures, tables, etc.) as containers, the moved/copied elements are also bound to the containers. Of course, the above move/copy operation is also recorded in the undo redo, and the operations of deleting the element of the original page (the "move" function has this operation), adding the element of the new page, and adding the page need to be restored to the original state after the undo. After the new element of the target page is added, the selected state is kept, and the user can conveniently perform other operations.
