However, after reading the present application, it should be understood by those skilled in the art that the display operation method of the smart interactive tablet provided in the first embodiment may also include the feature that, in step S101, the hiding of the whiteboard element and the adding of the preview page in the window folder in step S102 may be triggered through various optional implementations of the first touch operation.
The following examples are described in detail.
Example one
Fig. 1 is a flowchart of a display operation method of an intelligent interactive tablet according to an embodiment of the present invention. The display operation method of the smart interaction tablet provided in the embodiment may be executed by an operation device of the smart interaction tablet, the operation device of the smart interaction tablet may be implemented in a software and/or hardware manner, and the operation device of the smart interaction 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 interaction tablet is taken as an actual carrier, and a detailed process of adjusting target selection, association and adjusting response when the display operation method of the intelligent interaction 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 display operation method of the intelligent interactive tablet specifically includes:
step S101, receiving a first touch operation generated on a whiteboard application interface, wherein whiteboard elements are displayed on 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. Referring to fig. 3, in addition to the contents written and added during the use and the contents inserted into the display (not shown in fig. 3), there are various tool controls for operating the above contents, which 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.
The whiteboard elements are various display contents generated on the whiteboard application interface during the use process of the whiteboard application, such as handwriting, inserted pictures, inserted forms, file display windows and the like. The file display window is a display area on the whiteboard application interface, and the display area is used for displaying a third-party file selected according to the file display operation, such as a picture, a document file, a multimedia file and the like. In the scheme, the detailed explanation is performed based on the file display window, the operation of other types of whiteboard elements in the implementation process of the scheme is the same as a whole, and the change in the specific implementation details will be described in particular.
The file display window is specifically triggered by a file display operation, which may be a combined operation implemented based on the toolbar 21. As shown in fig. 3, a tool control for opening a file is provided in the toolbar 21, when the tool control for opening a file is triggered, a file list interface 23 pops up, a default folder or a file and a sub-folder in a folder that has been opened last time are displayed in the file list interface 23, and when a file is selected, it is confirmed that a file display operation is received. The file in the file list interface 23 is selected by a preset selection operation of a certain file (including an icon area and a file name area) in the file list interface 23, such as single-finger touch click, multi-finger touch click, and the like; it is also possible that the file is dragged from the file list interface 23 to an area outside the file list interface 23 in the whiteboard application interface 20, which is illustrated in fig. 3 by the way of dragging selection. That is, the file presentation operation implemented in the whiteboard application interface 20 is a combination of actions, including at least triggering of the file open control to pop up the file list interface 23 and selection of a specific file in the file list interface 23. This is also the main implementation manner determined by the usage characteristics of the whiteboard application, because the operation requirements of the intelligent interactive tablet generally appear in the usage process of the whiteboard application, and what is needed is to quickly display other files without switching or adjusting the whiteboard application interface 20 while the whiteboard application interface 20 is displaying. A plurality of file display windows can be obtained by performing file display operations for a plurality of times or opening a plurality of third-party files in sequence, and 2 file display windows are opened in fig. 4 and are respectively marked as 22a and 22 b.
The first touch operation in this embodiment is a type of operation, which may cause the selected whiteboard element to enter a hidden state, and add a corresponding browsing page in the window folder, where the first touch operation may be specifically implemented by triggering a preset control, or may be implemented by a specific gesture. As shown in fig. 4, the file display window 22a and the file display window 22b both display element hiding controls, and the user has an action of triggering the element hiding controls, that is, a first touch operation occurs in fig. 4.
And step S102, adding a preview page of the whiteboard element confirmed by the first touch operation in a window folder of the whiteboard application interface, and hiding the whiteboard element confirmed by the first touch operation in the whiteboard application interface.
As shown in fig. 4, the window clip 211 is displayed on the toolbar 21, and the window clip 211 may be displayed all the time or may be displayed after a whiteboard element is added to the whiteboard application interface, for example, since no whiteboard element is currently displayed in fig. 3, the window clip 211 is not displayed. The window folder 211 is a tool control for managing the display state of the whiteboard element, and as for a specific trigger result, the feedback after the window folder 211 triggers cannot change the content of the whiteboard element in the whiteboard application interface, but only can change the display state (display or hide) of the whiteboard element. In the window clip 211, only the preview page corresponding to the whiteboard element currently in the hidden state is retained, for example, in fig. 4, no whiteboard element currently enters the hidden state, so the window clip 211 is blank and no preview page exists.
The preview page may be implemented by screenshot of the confirmed whiteboard element or by redrawing handwriting. The screenshot can be a full screenshot or a simplified screenshot. Generally speaking, the size of an intelligent interactive panel is large, a large commercial intelligent interactive panel is 80 inches, a third-party file is required to be clearly presented through a file presentation window in the intelligent interactive panel, the file presentation window may be about 10 inches, and the size of the file presentation window can be adjusted, so that picture data obtained based on a complete screenshot of display content in the file presentation window may be large, and therefore, during specific screenshot, the display content can be reduced by a certain proportion, for example, half, three quarters and then simplified screenshot are performed, the content capable of presenting corresponding display elements can be obtained, meanwhile, the screenshot which occupies no buffer space is occupied, and balance between a display effect and a storage space is achieved. Redrawing the handwriting mainly aims at the hiding of the handwriting, which is equivalent to extracting the display parameters of the handwriting in the first display page, and then drawing the scaled-down handwriting in the page display window by taking the size of the page display window as reference.
Step S103: and when the writing operation generated on the whiteboard application interface is received, generating a writing track on the whiteboard application interface.
In this embodiment, the writing operation performed on the whiteboard application interface is similar to the overall implementation of the conventional writing operation in the whiteboard application in the prior art, and the local part can be adaptively adjusted with respect to the file display window. For example, if the starting point of the writing track corresponding to a certain writing operation is not in the file display window, the writing operation is confirmed to be valid, and the writing track is correspondingly generated, if the writing track is overlapped with the file display window, the overlapped part is generated below the file display window so as to adapt to the top display of the file display window, and the original overlapped writing track can be displayed only after the file display window is moved away or the writing track is moved. For another example, if the starting point of the writing track corresponding to a certain writing operation is in the file display window, the writing operation is confirmed to be invalid, and the writing track is not generated; or confirming that the writing track corresponds to the writing behavior in the file display window, generating the writing track overlapped with the file display window in the file display window, and not generating and displaying the part of the writing operation which is not overlapped with the file display window.
It should be particularly noted that, in the present solution, the hiding (or displaying) of the whiteboard element and the generation of the writing track are not two independent operations, which are simply integrated, but are designed for a specific application scenario in the process of actually using the whiteboard application. For example, before some activity processes such as conferences, teaching or discussions, one or more existing files are prepared as an activity focus, and when an activity is actually performed, the existing files are displayed on a whiteboard application interface through a file display window, and meanwhile, notes, viewpoints, synopsis and the like are recorded on the whiteboard application interface according to the display content in the activity process, and finally, a complete activity record can be generated. Based on the activities performed by the scheme, if the current conference focus is processed, another conference focus needs to be switched for discussion, the file display window displaying the current conference focus can be hidden by one key, then the next conference focus is opened through file display operation, the hidden process of the current conference focus is simple to operate, and no interference is caused to the currently displayed whiteboard element after the hidden process.
Step S104: and when a second touch operation occurring in the window clip is received, displaying a whiteboard element corresponding to the preview page confirmed by the second touch operation, and deleting the preview page confirmed by the second touch operation in the window clip.
Specifically, the second touch operation is generally triggered by a control, that is, the whiteboard element whose display state needs to be restored needs to be specified in the window folder 211, and after one or more preview pages are selected in the window folder 211, the corresponding whiteboard element needs to be restored in the display state. Of course, the first touch operation may also be a gesture trigger, but based on the recording manner of the preview page in the window clip 211, the gesture trigger generally only enables the whiteboard elements corresponding to all the preview pages in the window clip 211 to restore the display state. On the basis of fig. 5, if an operation of selecting the preview page corresponding to the file presentation window 22a is detected in the window folder 211, the file presentation window 22a is restored to display, that is, to the interface state shown in fig. 4. The corresponding preview page is simultaneously deleted in the window clip 211 corresponding to the whiteboard element being restored to the display state.
In the above, by receiving a first touch operation occurring on a whiteboard application interface, the whiteboard application interface displays whiteboard elements; adding a preview page of the whiteboard element confirmed by the first touch operation in a window folder of the whiteboard application interface, and hiding the whiteboard element confirmed by the first touch operation in the whiteboard application interface; generating a writing track on the whiteboard application interface when receiving writing operation on the whiteboard application interface; and when a second touch operation occurring in the window clip is received, displaying a whiteboard element corresponding to the preview page confirmed by the second touch operation, and deleting the preview page confirmed by the second touch operation in the window clip. The whiteboard elements in the whiteboard application interface are quickly hidden through touch operation, the association area of the specific whiteboard elements can be quickly cleaned, and the complexity of cleaning the whiteboard elements is simplified.
Example two
Fig. 6 is a flowchart of a display 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. 6, the display operation method of the intelligent interactive tablet provided in this embodiment specifically includes:
step S201, receiving a first touch operation occurring on a whiteboard application interface, where whiteboard elements are displayed on the whiteboard application interface.
In a specific implementation process, the first touch operation for triggering the whiteboard element hiding display may be implemented in multiple ways at the same time, and is not limited to the triggering element hiding control shown in fig. 4. Specifically, the first touch operation includes at least one of the following operations:
the touch and click operation on the element hiding control of the whiteboard element is to trigger the element hiding control in the file display window 22a as shown in fig. 4, and trigger the element hiding control in the file display window 22b as shown in fig. 5, except for the element hiding control for a single whiteboard element. A control for performing batch operation on the selected whiteboard elements can be popped up when a plurality of whiteboard elements are selected, for example, an element hiding control, when the element hiding control under the scene is subjected to touch click operation, all the selected whiteboard elements enter a hidden state, and a preview page is correspondingly added to the window clip; other controls, such as a delete control, may be deleted in batches when a touch-click operation occurs. For writing handwriting, the writing handwriting and other handwriting usually form a composite information carrier, the element is usually inconvenient to be added with an element hiding control independently, otherwise, the display effect is influenced, and the element hiding control is usually displayed after the writing handwriting is selected.
And in the first hidden gesture of the selected whiteboard element, the first hidden gesture is mainly used as forward operation, namely the operation object is the selected whiteboard element, and the operation object enters a hidden state in response to the first touch operation. The first hidden gesture is mainly confirmed by the touch time, the touch position and the related change rule of the touch point. For example, the first hide gesture is confirmed by a multi-finger (specifically, two, three, four, and/or five finger) pinch gesture, which is illustrated in fig. 7 to enable the whiteboard element to be hidden. Specifically, the touch change rule and the touch time of 4 touch points are confirmed. For example, in fig. 7, a 4-point touch on the file display window 22a is detected, the distance between any two points can be obtained when the 4 points are detected initially, and D1 is obtained by summation, the distance between any two points is calculated similarly when the gesture operation is completed by the 4 points, and D2 is obtained by summation, if (D1-D2) is greater than the threshold T1, D2 is less than the threshold T2, and the duration T of the four-finger operation is less than the threshold T3, it is determined that the gesture is a multi-finger pinch gesture, the file display window 22a is hidden, and a corresponding preview page is added to the window clip 221, that is, the responded screen in fig. 7 is as shown in fig. 5. In addition to the multi-finger pinch gesture, the concealment of whiteboard elements can also be confirmed by a single-finger movement or a movement of multi-finger access. Specifically, at the user level, an element or elements are selected, the selected element is "thrown" toward a set area (border or window clip), and if, from the touch-responsive bottom layer, the initial velocity of the corresponding touch point is detected to be greater than a threshold V1 and the velocity of the whiteboard element when it contacts the set area is less than a threshold V2, the selected whiteboard element is collapsed. The speed here refers to the distance between two points and the acquisition time calculated every time two points are acquired during the operation of the user, the ratio of the distance to the acquisition time is the moving speed of the whiteboard element, and the initial speed of the element is calculated according to the last two points when the touch point leaves the screen. Then decays at a rate of N px/s, triggering the concealment of the whiteboard element if the set area is entered after the decay to the threshold V2.
And moving the whiteboard element to a preset area, and determining that the corresponding whiteboard element needs to be hidden. For example, as shown in fig. 8, the file display window 22a is selected and moved to the left boundary, and when the distance is smaller than the set pixel (for example, 5 pixels), the triggering of the hidden file display window 22a is confirmed. Of course, the preset area may be the window clip 221.
And the touch clicking operation of the one-key hidden control of the window clip is generally used for all hiding because the one-key hidden control of the window clip cannot provide the operation aiming at a certain whiteboard element. Naturally, the whiteboard elements with higher requirements can also be hidden, for example, handwriting is generally more discrete and is usually recorded sequentially, and the hidden requirement is not high; the file display window, the picture and the like have good integrity, the display area is large, and the hiding requirement is relatively high, so that the hiding of white board elements such as the file display window and the picture can be set.
And in the second hidden gesture of the selected whiteboard element, the second hidden gesture is mainly used as a reverse operation, namely, the operation object keeps displaying, and the unselected whiteboard element enters a hidden state in response to the first touch operation. The specific second hidden gesture is mainly based on the change of direction and distance. For example, the user moves back and forth one or more times from left to right, moves back and forth one or more times from top to bottom, and the like, from the specific calculation process, the farthest distances of the user moving in two directions are recorded, the farthest distances of the user moving in two directions are smaller than a set threshold, and the time of the operation is smaller than the set threshold, the user is considered to be a second hidden gesture operation, and at this time, the unselected elements are retracted. The second hide gesture shown in fig. 9 is to move right and then left in the file presentation window 22a without leaving in the middle, confirming that the file presentation window 22b should be hidden after the gesture.
The above implementation manner of the first touch operation may be provided simultaneously, but each operation hides one or more whiteboard elements only according to one of the confirmations. The multi-emitting mode design of the hidden state of the whiteboard element enables a user to select a proper mode to complete the hiding of the whiteboard element according to the position (close to the boundary or close to the window clip) of the user, the current display requirement (partial or total hiding) and other specific use states, and is suitable for various conditions to provide convenient operation.
Step S202, adding a preview page of the whiteboard element confirmed by the first touch operation to a window folder of the whiteboard application interface, and hiding the whiteboard element confirmed by the first touch operation in the whiteboard application interface.
And step S203, generating a writing track on the whiteboard application interface when receiving the writing operation on the whiteboard application interface.
Preferably, the present embodiment further comprises:
and step S204, when touch clicking operation in the display area of the window clip is received, displaying all preview pages and one-key display controls.
In this embodiment, each operation may be triggered at any time, for example, after the response of the first touch operation in fig. 5, the file display window 22b is hidden, the file display operation continues to be executed on the whiteboard application interface, and the file display window 22c is opened, where the display page at this time is generally as shown in fig. 10, on the basis of the above operations, a touch click operation occurs in the display area of the window folder, and in response to the touch electrode operation, as shown in fig. 10, all preview pages are displayed, and a one-key display control is displayed, and the one-key display control may be identified by text, for example, the "one-key display" is identified. In addition to the one-key display control, the one-key hiding control can be displayed at the same time, the whiteboard elements corresponding to all the preview pages are restored to the whiteboard application interface for display when the one-key hiding control is triggered, all the whiteboard elements are hidden when the other one is triggered, and the corresponding preview pages are added into the window folder.
Preferably, the present embodiment further comprises:
and step S205, when receiving the touch click operation on the preview page, displaying the whiteboard element corresponding to the preview page, and deleting the preview page in the window folder.
And the touch clicking operation on the preview page indicates that the display state of the whiteboard element needs to be restored, and correspondingly restores the whiteboard element to the initial position, and if a new whiteboard element is added to the initial position during the hiding period, the whiteboard element can be restored to the nearest blank area. Deleting the preview page can release the cache, can also reduce the display interference on the preview page of other whiteboard elements which are entirely in a hidden state, and improve the operation speed. After clicking on the preview page corresponding to the document presentation window 22b on the basis shown in fig. 10, as shown in fig. 11, the document presentation window 22b is restored to display, and only the preview page of the document presentation window 22a remains in the window folder.
Preferably, the present embodiment further comprises:
step S206: and when touch clicking operation on the one-key display control is received, displaying whiteboard elements corresponding to all preview pages, and deleting all the preview pages in the window clip.
The one-key display is helpful for the user to quickly restore the display states of all activity records when the activity is finished, so that the interactive summary is quickly carried out on the basis of the activity records, and the last link of the activity is perfected.
It should be noted that the steps described above are not performed in a particularly strict order of execution, and the above numbering and description order is merely to accommodate the representation in fig. 6. In fact, in a complete usage cycle of the whiteboard application, as long as there is a prerequisite basis for executing the steps, other steps may be correspondingly executed according to the determination result of the touch event.
In the above, the various ways of triggering the hiding process of the display elements can be adapted to the real-time station of the user of the whiteboard application, and provide the operation as convenient and fast as possible. The one-key hiding and one-key recovery of the display elements also improve the sorting speed of the display states of the multiple display elements.
