The embodiment of the application provides a method for erasing a label, which can be applied to a server or a terminal. As shown in fig. 1, the method comprises the following steps:
s110, when receiving the marking operation, obtaining the marking content and the corresponding timestamp.
Illustratively, the labeling content can be Chinese characters, formulas and graphics, and the main body for performing labeling operation can be a finger or an adaptive touch pen. Taking the electronic whiteboard as an example, the sensing mode of the electronic whiteboard screen can be electromagnetic sensing, infrared sensing or pressure sensing. Taking infrared induction as an example, infrared receiving and emitting geminate transistors are densely distributed on the surface of an infrared induction electronic whiteboard screen to form scanning grids in the horizontal and vertical directions, so as to form a scanning plane grid. The method for acquiring the marked content and the corresponding timestamp may be that when the marking operation main body marks the electronic whiteboard, the specific coordinate position of the marking operation main body on the grid is determined through the on-off of the infrared geminate transistor optical path on the scanning plane network, the marked content is determined according to the change of the coordinate position, the time for forming the marked content is accurately recorded through a clock of the electronic whiteboard, and the time for forming the marked content is acquired as the timestamp of the marked content. The embodiment of the present application does not limit how to obtain the annotated content and the corresponding timestamp, and those skilled in the art can determine the annotated content and the corresponding timestamp as needed.
And S120, acquiring the current labeling state.
For example, the current marking state may refer to whether it is currently in a writing stopped state or whether it is currently in a continuous writing state. The method for acquiring the current labeling state may be determined according to a time difference between the current time and the last labeling operation signal, or according to a time difference between the current time and a time stamp of the last labeling content. The embodiment of the present application does not limit how to obtain the current labeling state, and those skilled in the art can determine the current labeling state as needed.
And S130, erasing the marked content according to the timestamp and the current marked state.
Illustratively, according to the timestamp and the current tagging state, the erasing operation on the tagged content can be performed in a manner that an erasing sequence is determined according to the timestamp and whether erasing is performed is determined according to the current tagging state; or determining whether to erase according to a difference between the timestamp and the current time, and determining an erasing speed according to the current marking state, for example, if the difference between the timestamp of a certain marked content and the current time is greater than a time threshold, it indicates that the marked content has been determined to be deleted, when the current marking state is a writing stop state, the erasing speed is a first speed value, the current marking state is a continuous writing state, and the erasing speed is a second speed value. The embodiment of the application does not limit the erasing operation mode of the marked content according to the timestamp and the current marking state, and a person skilled in the art can determine the erasing operation mode according to the requirement.
The mark erasing method provided by the invention can erase the marked content according to the received timestamp and the marked state, and does not need to use an eraser function in the electronic whiteboard or a handheld eraser matched with the electronic whiteboard to manually erase the mark, so that the convenience of operation is improved.
As an optional embodiment of the present application, step S110 includes:
firstly, when the marked content is obtained by a plurality of discontinuous touch operations, obtaining a mark formed by each touch operation and a timestamp corresponding to the mark;
illustratively, whether Chinese characters, formulas or graphics are the complete content formed by identifying a plurality of intermittent touch operations. The manner of obtaining the mark formed by each touch operation and the timestamp corresponding to the mark is the same as S110, and details are not repeated here.
Secondly, the last marked time stamp is used as the time stamp of the marked content.
Illustratively, the annotation content composed of each mark is completely identified, and character image segmentation is involved in the identification process, that is, all marks composing one annotation content are extracted from a plurality of marks so as to identify the segmented character image, and the time stamp of the last mark in the annotation content after character image segmentation is taken as the time stamp of the whole annotation content.
As an alternative embodiment of the present application, as shown in fig. 2, step S120 includes:
s121, determining whether a touch operation is received within a target time length, entering S122 when the touch operation is received within the target time length, and executing S123 when the touch operation is not received within the target time length;
for example, the method for determining whether the touch operation is received within the target duration may be based on the timestamp, and determine whether a difference between a timestamp of the last tagged content and the current time exceeds the target time, and when the difference between the timestamp of the last tagged content and the current time exceeds the target time, it indicates that a new touch operation is not received within the target time; and when the difference value between the timestamp of the last marked content and the current time exceeds the target time length, the touch operation is received in the target time length. The target duration may be 8 seconds. The embodiment of the application does not limit how to determine whether the touch operation is received within the target duration and the target duration, and a person skilled in the art can determine the touch operation as needed.
S122, determining that the current state is a continuous labeling state;
illustratively, when the touch operation is received within the target time length, which indicates that a new touch operation is performed within the target time length, the electronic whiteboard is currently performing continuous input, and the current state is determined to be a continuous labeling state.
And S123, determining that the current state is a labeling stopping state.
For example, when no touch operation is received within the target duration, which indicates that no new touch operation is performed within the target duration, and the electronic whiteboard has no new input within the target duration, it is determined that the current state is the state of stopping tagging.
As an optional embodiment of the present application, step S120 includes:
firstly, when the current state is a continuous labeling state, acquiring current labeling time;
for example, the manner of acquiring the current marked time may be determined by acquiring a clock signal in the current electronic whiteboard.
Secondly, according to the timestamp and the current marking time, the marking content with the time interval larger than the target interval duration is erased.
Illustratively, when the time interval between the current marking time and the timestamp of the marking content is longer than the target interval duration, erasing the marking content, where the marking content to be erased may be the marking content of which the time interval between the timestamp of the marking content and the current marking time which is always in a continuous writing state is longer than the target interval duration; or when the writing stop state is changed into the continuous writing state, the label content which is not erased is left. The target interval duration may be determined according to actual needs, for example, the target interval duration is set to 25 seconds. The erasing mode can be to erase the marked contents unified as the same time stamp at the same time, or to erase the marked contents in sequence according to each marked time stamp forming the marked contents, and the erasing time interval can be the same as the original marking time interval. Electronic whiteboard screens are generally divided into two layers: the drawing layer is displayed on the upper layer, and the background layer is displayed on the lower layer. The erasing principle can be that the corresponding marked content displayed on the drawing layer of the electronic whiteboard is transparently set while the marked content is deleted in the memory, so that only the color of the background layer is displayed on the surface of the electronic whiteboard, and the purpose of erasing the marked content from the electronic whiteboard is achieved. The erasing manner and the erasing principle are not limited in the embodiment of the present application, and those skilled in the art can determine the erasing manner and the erasing principle according to the needs.
According to the mark erasing method provided by the invention, when the mark state is a continuous writing state and the difference between the time stamp of the mark content and the current time exceeds the time threshold, the mark content displayed on the electronic whiteboard is sequentially erased according to the time stamp sequence, and when the mark of a user is only used as auxiliary expression but not as an explanation key point, the mark is erased according to the time stamp sequence, so that the time for displaying each mark content on the screen is the same, the electronic whiteboard can erase the mark which is not needed in time when being continuously used, a space is provided for establishing a new mark, and the erasing of the electronic whiteboard is more reasonable and intelligent.
As an optional embodiment of the present application, step S120 includes:
and when the current state is the state of stopping marking, erasing the marked contents in sequence from the earliest timestamp.
For example, the earliest timestamp may be the earliest timestamp of the remaining marked content after erasing the marked content when the last writing is stopped, or may be the earliest timestamp of the remaining marked content when the continuous writing state is changed to the stopped state, and the erasing manner, time interval, and principle thereof are the same as those of the erasing manner, time interval, and principle of the continuous marking state, and are not described again.
According to the label erasing method provided by the invention, when the label state is the writing stop state, the label contents displayed on the electronic whiteboard are sequentially erased according to the time stamp sequence, and when the user label is only used as auxiliary expression and not as an explanation key point, the label is erased according to the time stamp sequence, so that the user can more intelligently erase the label when stopping using the electronic whiteboard.
As an optional embodiment of the present application, after taking the timestamp of the last marker as the timestamp of the annotation content, the method includes: establishing a first linked list according to the corresponding relation between each mark and the timestamp corresponding to the mark; establishing a second linked list according to the corresponding relation between the marked content and the timestamp; and adding indexes to the first linked list and the second linked list.
Illustratively, each marker received by the electronic whiteboard and the acquired timestamp information corresponding to the marker are saved in a linked list in a timestamp order. The content formed by the marks is divided into different mark contents through character image division, the mark contents are identified, the identified mark contents are stored in the second linked list, and the timestamp of the last mark stored in the first linked list corresponding to the second linked list is stored in the second linked list and is used as the timestamp of the mark contents in the second linked list. The marked content in the second linked list corresponds to a plurality of marks in the first linked list to form a one-to-many index relationship, so that the marked content can be directly deleted according to the sequence of the marked content stored in the second linked list when the marked content is erased, the effect displayed on the electronic whiteboard is to erase one character by one character according to the time stamp sequence of the marked content and the time interval of the marked content, and can also be deleted according to the sequence of the marks stored in the first linked list, and the effect displayed on the electronic whiteboard is to erase one by one according to the time stamp sequence of the marks and the time interval of the marks. Regardless of the erasure method, one list is deleted and the other list is also deleted because the two linked lists have an index relationship.
As an optional embodiment of the present application, after S130, as shown in fig. 3, the method further includes:
s131, determining whether a target erasing operation is received; when the target erase operation is received, S132 is performed.
Illustratively, the received target erase operation may be a specific symbol, such as x, or a touch target erase button signal received on the electronic whiteboard interface. Taking the received target erasing operation as a specific symbol x as an example, it may be that when the electronic whiteboard detects that x appears on the screen, it indicates that the target erasing operation is determined to be received, or when the electronic whiteboard detects that x appears on the screen, it may determine the size of x according to the coordinate position of x acquired by the electronic whiteboard, and when the size of x exceeds half of the screen of the electronic whiteboard, it indicates that the target erasing operation is determined to be received.
S132, erasing the marked content.
For example, the erasing of the annotation content may be to erase all the annotation contents in the screen, or to erase the annotation content in the target erasing operation range, for example, a rectangular range is defined by the portion of the screen with the drawing x according to four vertex coordinates thereof, and the annotation content in the rectangular range is erased, the principle of erasing is the same as that of the above-mentioned continuous annotation state, and details thereof are not repeated here.
The mark erasing method provided by the invention constantly detects whether a target erasing operation is received, and when the target erasing operation is received, part of the mark content is erased in a selected mode or the mark content is erased in a whole mode, so that a faster and more convenient mode is provided for erasing the electronic whiteboard.
As an optional embodiment of the present application, before S110, as shown in fig. 4, the method further includes:
s101, determining whether an automatic erasing instruction is received, and if the automatic erasing instruction is received, executing S102.
Exemplarily, the automatic erasing instruction may be determined by that the intelligent marking mode key in the marking mode of the electronic whiteboard receives a pressing operation, the electronic whiteboard marking mode is triggered to enter the intelligent marking mode, and the electronic whiteboard is determined to receive the automatic erasing instruction according to the received intelligent marking mode instruction; or when the intelligent marking mode menu bar in the marking mode on the electronic whiteboard receives the touch operation, triggering and sending a signal that the electronic whiteboard marking mode enters the intelligent marking mode, and determining that the electronic whiteboard receives the automatic erasing instruction.
S102, entering an automatic erasing mode.
Illustratively, the automatic erasing mode is the method implemented in the foregoing embodiment of the present invention to perform automatic erasing on an electronic whiteboard.
