Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the following detailed description of specific embodiments of the present application is given with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the matters related to the present application are shown in the accompanying drawings. Before discussing exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart depicts operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently, or at the same time. Furthermore, the order of the operations may be rearranged. The above-described process may be terminated when its operations are completed, but may have additional steps not included in the drawings. The processes described above may correspond to methods, functions, procedures, subroutines, and the like.

The interactive flat board applied by the scheme can be integrated equipment for controlling the content displayed on the display screen and realizing man-machine interaction operation through a touch technology, and integrates one or more functions of a projector, an electronic whiteboard, a curtain, sound equipment, a television, a video conference terminal and the like. Of course, the interactive tablet does not include a definition of the surface features of the display surface, e.g., the surface features of the interactive tablet may be planar, curved, or a splice of multiple planes, etc.

Typically, the interactive tablet is equipped with at least one operating system, wherein the operating system includes, but is not limited to, an android system, a Linux system, a Windows system, and a wintersweet system, which are used to control and coordinate the interactive tablet and the peripheral devices, so that various independent hardware in the interactive tablet can work as a stable whole. The interactive tablet comprises at least one display screen, e.g. the interactive tablet is configured with a display screen having touch functionality, i.e. a touch sensitive display screen. The touch sensitive display may be an infrared display, a capacitive display, a resistive display, an electromagnetic display, or a pressure sensitive display, among others. On a display screen with a touch function, a user can realize touch operation in a mode of touching the display screen by a finger or a writing pen, and correspondingly, the interactive flat plate detects a touch position and responds according to the touch position so as to realize the touch function. The interactive tablet can process touch operations received through the display screen through the operating system. Further, the interactive tablet may install at least one application based on the operating system, such as a whiteboard application installed in the interactive tablet. The whiteboard application may be an application program of the operating system, or may be an application program downloaded from a third party device or a server. When the whiteboard application is operated, a writing application interface is displayed on the display screen, writing operation can be performed in the range of the corresponding writing application interface in the display screen through fingers or writing pens, the interactive tablet can respond to the writing operation to display corresponding writing scripts in the writing application interface, character recognition can be performed on the writing scripts, and the recognized characters are displayed in the writing application interface. Text content and graphic elements can be inserted into the writing application interface, and optionally, the text content can be input through character recognition of writing handwriting, and can also be input through a virtual keyboard or an external physical keyboard.

The content erasing method provided by the application can be applied to erasing operation of text content on the interactive flat panel, for example, erasing part of the text content on the interactive flat panel. In the existing text content erasing scheme, the whole text content is generally taken as a text object, the whole text content is erased, a user cannot erase specific text content, the erasing operation of the text content erasing scheme is relatively fixed, and the flexibility is relatively poor. And under the use scene of the interactive tablet, the use of a mouse and a keyboard for editing the text is a difficult operation, and does not accord with the use habit of a user, so that the user experience is poor.

Based on the above, the content erasing method provided by the embodiment of the application is used for solving the technical problems of relatively fixed erasing operation, relatively poor flexibility and relatively poor user experience of the existing text content erasing scheme. The method aims at determining the residual text content from the text content according to the text positioning box after the erasing processing, and continuously displaying the residual text content, so that the dynamic erasing processing of the text content corresponding to the erasing operation is realized, the flexibility of the text erasing operation is effectively improved, and the user experience is improved.

Fig. 1 shows a flowchart of a content erasing method according to an embodiment of the present application, where the content erasing method according to the embodiment of the present application may be implemented in hardware and/or software, and integrated in a content erasing device (e.g. an interactive tablet).

The following description will be made taking an example in which the content erasing device performs a content erasing method. Referring to fig. 1, the content erasing method includes:

and S110, receiving a triggering operation of the content erasing function, determining text objects according to text content displayed in the writing application interface, and creating one or more text positioning boxes on the writing application interface according to each text object.

When the whiteboard application is operated on the content erasing device, a writing application interface is displayed on a display screen of the content erasing device, writing operation can be performed in a range corresponding to the writing application interface in the display screen through a finger or a writing pen, the content erasing device can respond to the writing operation to display corresponding writing handwriting in the writing application interface, text content can also be inserted in the writing application interface, at the moment, the writing handwriting and the text content are displayed on the writing application interface, and a font format corresponding to the text content is a standard font format. For example, the standard font format may be a font format that is encoded based on GB2312, times New Roman, or the like, which sets an encoding standard. When the content on the writing application interface needs to be erased, the content erasing function can be triggered to trigger operation so that the content erasing device enters an erasing mode, and a user can execute erasing operation on the content displayed on the writing application interface in the erasing mode.

When the content erasing device enters the erasing mode, text content displayed in the current writing application interface is determined, and a text object is created according to the text content. Alternatively, the text content in the same paragraph may be created as one text object, and when multiple text objects are displayed in the writing application interface, multiple text objects are determined according to the multiple text objects. The text content can be a single text or symbol, or a combination of a plurality of text and/or symbols, and one section of text content can be one line of text content or a plurality of lines of text content.

After determining text objects corresponding to text content displayed in the writing application interface, creating a hit text positioning box on the writing application interface according to each text object. The text positioning box is understood as a rectangular box for positioning text content on the writing application interface, and the text content on the writing application interface can be positioned according to the text positioning box. Each text object may correspond to create one or more text boxes, the size and location of which corresponds to the size and location of text content in the text object, each text box corresponding to a line of text content. For example, when a text object is determined from text content of one line, a text positioning box is created from the text object, and when a text object is determined from text content of a plurality of lines, a plurality of text positioning boxes are created from the text object.

In one embodiment, the erasing mode of the content erasing device may be triggered by an erasing function button provided on the content erasing device, or may be triggered by a medium type of the touch content erasing device, for example, when the medium type is detected as an eraser or an eraser.

In one possible embodiment, when one or more text positioning boxes are created on the writing application interface according to each text object, the content erasing method provided by the scheme can be that the text positioning boxes are created on the writing application interface according to the size information and the position information of each line of text content in each text object.

For example, after determining text objects corresponding to text contents displayed in the writing application interface, determining, for each text object, a text positioning box corresponding to each line of text contents is created on the writing application interface according to size information (including length and width) and position information of each line of text contents in the text object. At this time, the size (including length and width) and position of the text positioning box are consistent with the size information and position information of the text content of the corresponding line, and the text positioning box can cover the text content of the corresponding line. According to the text object erasing method and device, the text positioning boxes are accurately created according to the size information and the position information of each line of text content in the text object, so that the accuracy of erasing the text content is improved.

In one possible embodiment, when one or more text positioning boxes are created on the writing application interface according to each text object, the text positioning boxes with the first transparency can be created on the writing application interface according to each text object.

Illustratively, after determining the text objects, a text bounding box of a first transparency is created on the writing application interface from each text object. Wherein the transparency of the first transparency may range from 50% to 100%. For example, when the first transparency is 100%, the text positioning box is set to be fully transparent, the creation of the text positioning box does not influence the display effect of text contents in the writing application interface, the text positioning box is generated under the condition that a user does not feel, and the use experience of the user is improved. When the first transparency is smaller than 100%, the text positioning box can be observed in the writing application interface, and a user can quickly and accurately determine text content capable of performing the second erasing operation through the text positioning box, so that the content erasing efficiency is improved, and the user experience is improved. Optionally, the user may set one or more combinations of the first transparency, the border color, and the fill color according to the display effect requirements for the text box. According to the scheme, the text positioning box with the first transparency is created on the writing application interface, so that the display effect of the text positioning box is optimized, and the user experience is optimized.

In one embodiment, the content erasing method provided by the scheme comprises at least one of a first mode of receiving the content erasing function triggering operation triggered by the content erasing function button, a second mode of receiving the content erasing function triggering operation triggered by the setting gesture, a third mode of receiving the content erasing function triggering operation triggered by the setting touch action and a fourth mode of receiving the content erasing function triggering operation triggered by the touch display screen of the touch object with the set medium type.

For example, for mode one, a content erase function button may be provided in a whiteboard application, and the user may trigger the content erase function triggering operation by clicking the content erase function button. Alternatively, the content erasing function button may be provided in the operation panel, and the content erasing function triggering operation may be triggered on the content erasing function button in the operation panel by calling out the operation panel. For the second mode, a shooting device (such as a camera or an infrared camera) configured or externally connected on the content erasing device can be used for detecting gesture actions of a user, and when the gesture actions of the user are detected as setting gestures, it is determined that the user triggers a content erasing function triggering operation, for example, the setting gestures can be hand-up erasing gestures. For the third mode, the touch action performed on the display screen may be detected, and when the set touch action is detected, it is determined that the user triggers the content erasing function to trigger operation, for example, a touch track corresponding to the set touch action may be a track corresponding to the back and forth erasing on the display screen, or a track corresponding to a touch area larger than the set area (for example, the track is pasted on the display screen by using a palm to move). For the fourth mode, the medium type of the touch object of the touch display screen can be detected, and when the medium type of the touch object performing the touch operation on the display screen is detected to be a set medium type (for example, the set medium type is rubber, palm, handwriting pen holder and the like), it is determined that the user triggers the triggering operation of the content erasing function. Optionally, the detection of the medium type of the touch object may be performed by an elastic wave detection unit configured on the content erasing device, for example, detecting an elastic wave generated when the touch object performs a touch operation on the display screen, and determining that the medium type of the touch object is the set medium type when the detected elastic wave matches with the elastic wave generated when the touch object performs the touch operation on the display screen. According to the scheme, the trigger operation of the content erasing function is detected, so that the time for creating the text positioning box is accurately determined, and the content is accurately erased.

And S120, receiving a first erasing operation on the writing application interface, and erasing writing marks on the writing application interface according to the first erasing operation.

Illustratively, after entering the erase mode, the user may initiate a first erase operation on the writing trace to be erased on the writing application interface using a stylus, eraser, hand, or other medium. The content erasing device determines writing marks hit by the first erasing operation after detecting the first erasing operation performed on the writing application interface, and erases the writing marks hit by the first erasing operation on the writing application interface.

S130, receiving a second erasing operation on the writing application interface, and determining a text positioning box hit by the second erasing operation.

For example, after entering the erase mode, the user may initiate a second erase operation on the text content to be erased on the writing application interface using a stylus, eraser, hand, or other medium. After detecting the second erasing operation performed on the writing application interface, the content erasing device determines a text positioning box hit by the second erasing operation.

When the user triggers the second erasing operation according to the position of the text content to be erased on the writing application interface, the text positioning boxes hit by the second erasing operation comprise the text positioning boxes corresponding to the text content to be erased. Alternatively, the text box hit by the second erase operation may be determined based on the size and location of each text box and the location of one or more erase points of the erase path traversed by the second erase operation.

And S140, performing erasure processing on the hit text positioning box according to the second erasure operation.

Illustratively, after determining the text positioning box hit by the second erasing operation, erasing the hit text positioning box according to the second erasing operation, and determining the text positioning box after the erasing process. The erasing processing on the text positioning box may be erasing a portion corresponding to the second erasing operation in the hit text positioning box, for example, erasing a corresponding length from the hit text positioning box according to an erasing range corresponding to the second erasing operation. The missed text positioning boxes keep the original shape, and after the hit text positioning boxes are erased, the hit text positioning boxes are divided into erased text positioning boxes and residual text positioning boxes, and the shape corresponding to the addition of the erased text positioning boxes and the residual text positioning boxes is the shape of the hit text positioning boxes.

In the process that the user triggers the second erasing operation (the second erasing operation is completed after the user drops the eraser to start the erasing operation, a plurality of erasing points on the erasing path of the second erasing operation are continuously detected, a hit text positioning frame can be determined according to each erasing point in sequence, erasing processing is carried out on the hit text positioning frame, the text positioning frame is used as a new text positioning frame in the next erasing point after erasing processing is carried out on the basis of one erasing point, and the original text positioning frame can be deleted, so that the accuracy of content erasing is ensured. Based on this, in a process of triggering the second erasing operation, one text positioning box is repeatedly hit and erased, and the shape (length) of the corresponding remaining text positioning box is gradually reduced.

The text positioning box is used for positioning the text to be erased in the writing application interface, and the text to be erased is positioned in the writing application interface.

And S150, determining the residual text content from the text content according to the text positioning box after the erasure processing, and displaying the residual text content continuously.

For example, after the user completes the second erasing operation, the text positioning boxes left after the last second erasing operation is performed on the hit text positioning boxes are determined, the rest text content is determined from the text content according to the rest text positioning boxes (including the missed text positioning boxes and the rest text positioning boxes after erasing), and the rest text content is displayed continuously. The displaying of the remaining text content may be that after one or more text content words are erased, the original position of the erased text content is removed from the redisplayed text, and the original position of the erased text content is filled with the subsequent remaining text content, so that after part of the text content is erased, the displaying of the remaining text content is coherent, instead of freeing the original position of the erased text content.

At this time, the text content displayed on the writing application interface is composed of the remaining text content, and the text content other than the remaining text content in the original text content is deleted, so that the display effect that part of the text content is erased is presented. In one embodiment, when the content of the remaining text is displayed continuously, the positions of the characters and/or symbols of the remaining text are adaptively adjusted, so that the display effect after the content is erased is improved.

In the embodiment of the application, the text objects are determined according to the text content displayed in the writing application interface, one or more text positioning boxes are created on the writing application interface according to each text object, the writing handwriting on the writing application interface is erased according to the first erasing operation on the writing application interface, the erasing processing is carried out on the text positioning boxes hit by the second erasing operation on the writing application interface, the residual text content is determined from the text content according to the text positioning boxes after the erasing processing, the residual text content is displayed continuously, the dynamic erasing processing of the text content corresponding to the second erasing operation is realized, and the self-adaptive adjustment of the text content after the erasing processing is realized through the continuous display of the residual text content, so that the flexibility of the text erasing operation is effectively improved, and the user experience is improved.

On the basis of the above embodiment, fig. 2 shows a flowchart of another content erasing method according to an embodiment of the present application, where the content erasing method is embodied in the above content erasing method. Referring to fig. 2, the content erasing method includes:

and S210, receiving a triggering operation of a content erasing function, determining text objects according to text content displayed in a writing application interface, and creating one or more text positioning boxes on the writing application interface according to each text object.

S220, receiving a first erasing operation on the writing application interface, and erasing writing marks on the writing application interface according to the first erasing operation.

S230, receiving a second erasing operation on the writing application interface, determining an erasing range corresponding to an erasing point of the second erasing operation on the writing application interface, and determining a text positioning box intersected with the erasing range as a text positioning box hit by the second erasing operation.

Illustratively, after receiving a second erase operation performed on the writing application interface, an erase range corresponding to each erase point in an erase path of the second erase operation on the writing application interface is determined. In one embodiment, the erasing range may be a circular range with the erasing point as a center and the set length as a radius, wherein the set length may be determined according to the set width of the eraser.

After determining the erasure range, determining a text bounding box having an intersection with the erasure range, and determining the text bounding box having an intersection with the erasure range as the text bounding box hit by the second erasure operation. According to the scheme, the hit text positioning frame is accurately determined according to the intersection condition of the erasing range and the text positioning frame, which is determined by the erasing point of the second erasing operation, so that the hit efficiency and accuracy of the text positioning frame are effectively improved.

In one possible embodiment, when determining the text positioning box intersected with the erasing range as the text positioning box hit by the second erasing operation, the content erasing method provided by the scheme can be that in the case that a plurality of text positioning boxes intersected with the erasing range exist, the uppermost text positioning box in the plurality of text positioning boxes intersected with the erasing range is determined as the text positioning box hit by the second erasing operation.

When a plurality of text positioning boxes intersected with the erasing range are determined according to the erasing range corresponding to the erasing point, a hierarchical relationship between the text positioning boxes intersected with the erasing range is determined, and the text positioning box at the uppermost layer in the text positioning boxes is determined to be the text positioning box hit by the second erasing operation. For example, when multiple pieces of text content are overlaid on the early writing application interface, the second erasing operation may hit text positioning boxes corresponding to multiple overlaid text content at the same time, and the text positioning box on the uppermost layer of the text positioning boxes may be determined as the text positioning box hit by the second erasing operation.

Alternatively, the hierarchy of text boxes may be determined based on the corresponding text content. For example, the later (i.e., closer to the current time) the text content corresponding to the text positioning box is added to the writing application interface and/or is manipulated (e.g., text editing, text movement, etc.), the higher the corresponding level.
