Detailed Description
In order to make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
It should be understood that the embodiments described are only a few embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the application, as detailed in the appended claims.
In the description of the present application, it is to be understood that the terms "first," "second," "third," and the like are used solely to distinguish one from another and are not necessarily used to describe a particular order or sequence, nor are they to be construed as indicating or implying relative importance. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate. Further, in the description of the present application, "a plurality" means two or more unless otherwise specified. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
The intelligent interactive flat panel is integrated with the function of the electronic whiteboard. When the intelligent interactive tablet is in the electronic whiteboard mode, an electronic whiteboard interface (i.e., a user interface of the intelligent interactive tablet) of the intelligent interactive tablet is equivalent to a handwriting pad with a large area, and a user can write on the interface. The written content may be, for example, handwriting, insert shapes, insert pictures, insert forms, and the like. After writing is completed, the user can also edit the written content. The edit may be, for example, an addition, deletion, or modification. Taking written content as an example of text, the modification may be, for example, adjusting the font, size, position, etc. of the text.
The embodiment of the application does not limit the manner in which the above-mentioned intelligent interactive tablet implements the electronic whiteboard function, for example, the electronic whiteboard function is a system function of the intelligent interactive tablet, or an application program of the electronic whiteboard runs on the intelligent interactive tablet.
Currently, when a user writes on an electronic whiteboard interface of an intelligent interactive tablet, the intelligent interactive tablet records each step of recent operations (including writing, editing, and the like) performed by the user on the electronic whiteboard interface in an operation history list. The specific recording mode is to store "the content displayed on the interface after the step is performed" as one version of the written content in the operation history list. In this way, the user can implement the rollback of the writing content version through the revocation on the electronic whiteboard interface.
Currently, a user may return to one operation of the user on the electronic whiteboard interface recorded in the operation history list by clicking a cancel button once. If the user desires to rollback to a version that is not the last version of the current version, the user needs to rely on memory and blind operations to click the undo button multiple times to rollback to the desired version.
In addition, since the storage space corresponding to the operation history list is limited, if the version recorded in the operation history list reaches the upper limit of storage, the version of the newly recorded written content will replace the version recorded with the longest time in the operation history list. However, in the above-described rollback method, the user needs to perform a blind rollback operation by means of memory, and if the user desires to replace the rollback version with a newly recorded version of the written content in the operation history list, the user cannot rollback the written content to the desired version even if the user clicks the undo button multiple times.
Fig. 1 is a schematic diagram of an electronic whiteboard interface of an intelligent interactive tablet. As shown in fig. 1, taking an example that a user writes a mathematical question on an electronic whiteboard interface, and an equation and an answer of the question, the content of writing displayed on the electronic whiteboard interface is as shown in fig. 1 (a). If the user needs to return the written content to a version with only the math topic (i.e. no algebra and answer language), such as the written content shown in fig. 1 (b), the user can implement the return by clicking the cancel button on the user interface.
Assuming that the user performs 9 operations on the electronic whiteboard interface to complete the writing of the formula and answer of the question, the user needs to click the cancel button 9 times by means of his own memory and blind operation to return to the writing content shown in (b) of fig. 1.
If the operation history list can record only 8 versions of the written contents, the version of the written contents that the user desires to rewind has been replaced in the operation history list by the newly recorded version of the written contents. In this scenario, no matter how many times the user clicks the undo button, the user cannot rollback to the desired version.
That is, the above rollback mode is cumbersome to operate, inefficient, and poor in user experience. Similarly, when the writing content on the electronic whiteboard interface is restored to a certain version, the similar problems as described above also exist.
In view of the above problem, the user needs to implement rollback or recovery by means of memory and blind operation, and therefore, an embodiment of the application provides an operation method of an intelligent interactive tablet, which can present a preview list to the user in a visual manner, so that the user can select a version of a writing content required by the user in a visual manner, so that the user can directly rollback or recover the required writing content across multiple records, thereby simplifying rollback or recovery operations, improving rollback or recovery efficiency, and further improving user experience.
It should be understood that the method of the embodiment of the present application may be applied to any device with an electronic whiteboard function, for example, an intelligent interactive tablet, or other devices running an "application with an electronic whiteboard function". Such as devices running a video conferencing application, etc. For convenience of description, the following embodiments are all exemplified by being applied to a smart interactive tablet.
For example, the hardware part of the intelligent interactive flat panel related to the embodiment of the present application is composed of a touch display module, an intelligent processing system (including a controller), and the like, and is combined together by an integral structural member, and is supported by a dedicated software system, wherein the touch display module includes a display screen, a touch assembly and a backlight assembly, the backlight assembly is used for providing a backlight source for the display screen, the display screen generally adopts a liquid crystal display device for displaying pictures, and the touch assembly is arranged on the display screen or at the front end of the display screen, and is used for collecting touch operation data of a user, and sending the collected touch operation data to the intelligent processing system for processing.
In actual use, the display screen of the intelligent interactive tablet displays image data, when a user clicks content displayed on the display screen through a touch object such as a finger or a touch pen, for example, clicks a graphical button displayed on the display screen, touch data are collected by a touch component of the intelligent interactive tablet, so that the touch component converts the touch data into coordinate data of a touch point and then sends the coordinate data to the intelligent processing system, or the coordinate data are converted into coordinate data of the touch point by the intelligent processing system, after the coordinate data of the touch point are obtained by the intelligent processing system, corresponding control operation is realized according to a preset program, the display content of the display screen is driven to change, and diversified display and operation effects are realized.
Touch components are distinguished from technical principles and can be divided into five basic categories; a vector pressure sensing technology touch component, a resistance technology touch component, a capacitance technology touch component, an electromagnetic technology touch screen, an infrared technology touch component, and a surface acoustic wave technology touch component. According to the working principle of the touch assembly and the medium for transmitting information, the touch assembly can be divided into four categories: resistive, capacitive, electromagnetic, infrared, and surface acoustic wave.
When a user touches the display screen by a finger or a pen, the touch assembly can acquire data of touch points and send the data to the intelligent processing system, and then different functional applications are realized along with software built in the intelligent processing system, so that touch control of the intelligent processing system is realized.
The 'screen' and 'large screen' mentioned in the application refer to the display screen of the intelligent interactive flat panel; the intelligent interaction panel displays a certain interface, namely the display screen of the intelligent interaction panel displays the interface.
The following describes in detail an operation method of the smart interactive tablet provided in the embodiment of the present application with reference to specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
In several embodiments described below, embodiment 1 provides how to visually roll back or restore to the desired written content. Embodiment 2 provides a procedure of how to record recent operations of the user on the electronic whiteboard interface to support the rollback operation or the recovery operation of the foregoing embodiment 1.
It should be noted that, for the sake of brevity, this description does not exhaust all alternative embodiments, and it should be understood by those skilled in the art after reading this description that any combination of features may constitute an alternative embodiment as long as the features are not mutually inconsistent. The features described in the different embodiments, which are not mutually inconsistent, may also be arbitrarily combined to form alternative embodiments.
The following describes example 1 and example 2 in detail.
Example 1
The embodiment of the application discloses an operation method of an intelligent interactive panel, which is applied to the intelligent interactive panel.
Fig. 2 is a schematic flowchart of an operation method of an intelligent interactive tablet provided in the embodiment of the present application, fig. 3 is a schematic diagram of an electronic whiteboard interface provided in the embodiment of the present application, and fig. 4 is a schematic diagram of another electronic whiteboard interface provided in the embodiment of the present application. The following describes in detail an operation method of the smart interactive tablet according to an embodiment of the present application with reference to fig. 2 to 4.
As shown in fig. 2, the method comprises the steps of:
s101, displaying the writing content and the operation buttons of a first version on an electronic whiteboard interface of an intelligent interactive flat plate; wherein, the operation button is a cancel button or a recovery button.
The application scene related to the embodiment of the application is a scene that the intelligent interactive tablet is in an electronic whiteboard mode, namely, an interface displayed by the intelligent interactive tablet at present is an electronic whiteboard interface.
In an exemplary embodiment of the present application, the electronic whiteboard interface of the smart interactive tablet may be as shown in fig. 3, for example, when the electronic whiteboard interface includes the currently displayed first version of the writing content, and the operation buttons. Wherein, the operation button can be a cancel button or a recovery button.
When the operation button is a cancel button, the cancel button is used for realizing the backspace of the written content. Illustratively, the cancel button may be, for example, as shown in fig. 3, or may be other buttons capable of implementing rollback. When the operation button is a recovery button, the recovery button is used for recovering the written content. Illustratively, the restore button may be, for example, as shown in fig. 3, or may be another button capable of restoring the written content. The embodiment of the application does not limit the implementation mode, the naming and the position on the electronic whiteboard interface of the cancel button and the recovery button.
It should be understood that the restoration referred to herein may be, for example, restoring the written content from (b) in fig. 1 to (a) in fig. 1.
In this embodiment, the user performs at least one operation on the electronic whiteboard interface before the currently displayed first version of the written content. The operation described herein may be writing or editing. When a user performs multiple operations on the electronic whiteboard interface before the currently displayed first version of written content, part of the multiple operations may be writing, part of the multiple operations may be editing, or all of the multiple operations may be writing or all of the multiple operations may be editing, which is not limited in this embodiment of the present application.
S102, receiving a first touch operation aiming at the operation button.
It should be understood that the first touch operation is an operation of clicking the operation button, and may be a direct touch with a finger, a touch through another medium (e.g., a stylus pen), or the like.
S103, displaying a preview list; the preview list is used for displaying preview information of at least one historical version of the written content in the operation history list.
A historical version of the writing may be the writing that results from a step of a user's manipulation (including writing and editing, etc.) on the electronic whiteboard interface. For example, the user inputs "hello" on the electronic whiteboard interface for the first time, inputs "life" on the electronic whiteboard interface for the second time, and inputs "yes" on the electronic whiteboard interface for the third time. Then the written content containing "hello" is one version, the written content containing "hello life" is one version, and the written content containing "hello life yes" is one version.
In this embodiment, the preview information included in the preview list may be any information capable of representing the writing contents of the historical version. Illustratively, the preview information may be a preview image of the historical version of the written content, such as the preview list shown in fig. 3; alternatively, the preview information may be a step of a user performing a specific operation (including writing and editing, etc.) on the electronic whiteboard interface when the obtained writing content is obtained, such as a preview list shown in fig. 4.
In an exemplary embodiment of the present application, the preview list is displayed when a first touch operation for the operation button is received. In another exemplary embodiment of the present application, when a first touch operation for the operation button is received and the first touch operation for the operation button is a long press operation, the preview list is displayed. That is, in the present embodiment, the first touch operation on the operation button is divided into two types, one is a single click and one is a long press. When the operation button is pressed for a long time, the intelligent interactive flat panel can be triggered to display a preview list containing preview information of at least two historical versions of the written content. Optionally, when the operation button is clicked, the smart interactive tablet can be triggered to execute a rollback operation or a one-step recovery operation. I.e., rollback or restore the previous version of the current version. That is, when the touch operation is a one-click operation, it is possible to switch from the writing contents of the first version to the writing contents of the previous version on the electronic whiteboard interface.
It should be understood that the long press operation referred to in the present embodiment refers to an operation in which the length of time for which the back button is touched is longer than the length of time for which the back button is clicked. The touch duration corresponding to the long press operation is not limited in the embodiment of the present application, and may be, for example, 1 second or 2 seconds.
The number of the preview information displayed in the preview list is not limited in the embodiment of the present application, and may be specifically determined according to the number recorded in the operation history list. In addition, the embodiment also does not limit the manner in which the preview list displays the plurality of pieces of preview information, for example, all the plurality of pieces of preview information may be displayed on the current interface, the plurality of pieces of preview information may be displayed in pages in a page turning manner, the plurality of pieces of preview information may be displayed in a page scrolling manner, and the like, and may be specifically set according to the user's needs.
And S104, receiving a second touch operation aiming at target preview information, wherein the target preview information is any preview information in the preview list.
It should be understood that the second touch operation is an operation of clicking the target preview information, and may be a direct touch with a finger, a touch through another medium (e.g., a stylus pen), or the like.
And S105, switching the writing content of the first version to the writing content of the historical version corresponding to the target preview information on the electronic whiteboard interface.
For example, taking the electronic whiteboard interface shown in fig. 3 as an example, assuming that the user needs to rewind the currently displayed written content, the smart interactive tablet may display the preview list shown in fig. 3 after receiving the first touch operation of the user on the cancel button.
Assuming that the intelligent interactive tablet receives a second touch operation of the user on the preview image with the label 2, the intelligent interactive tablet can directly jump from the writing content of the first version to the writing content of the version corresponding to the preview image with the label 2 to display.
It is assumed that in the actual operation process, the user performs 5 operations to change the written content of the version corresponding to the preview image labeled as 2 to the written content of the first version. If the method shown in fig. 1 is adopted, the user needs to click the cancel button 5 times by means of his own memory and blind operation, and can return to the written content of the version corresponding to the preview image with reference number 2. In the embodiment, the preview information of the writing content of at least one historical version is visually displayed on the preview list, so that the user can select the content of the version of the writing content required by the user based on the preview information, and the user can directly rewind or restore the required writing content across a plurality of records, thereby simplifying the rewinding or restoring operation, improving the rewinding or restoring efficiency and further improving the user experience.
The operation method of the intelligent interactive tablet provided by the embodiment can present the preview list to the user in a visual manner, so that the user can select the version of the writing content required by the user in a visual manner, and can directly rollback or restore the required writing content across a plurality of records, thereby simplifying the rollback or restoring operation, improving the rollback or restoring efficiency, and further improving the user experience.
The writing content of the at least one history version recorded by the operation history list in the above embodiment may be each step of the user's recent operation (including writing and editing, etc.) on the electronic whiteboard interface, which is automatically recorded by the intelligent interactive tablet. The number of records in the operation history list is a smaller value between "the number of times of user history operations" and "the maximum value of allowable records of the operation history list".
Optionally, the operation history list may be recorded by the smart interactive tablet triggered by the user.
