Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the relevant aspects of the present invention are shown in the drawings.

Example one

Fig. 1 is a flowchart of a table control method according to an embodiment of the present invention. The form control method provided by the embodiment can be executed by a form control device, which is implemented by software and/or hardware and integrated in the equipment. In this embodiment, an interactive smart tablet is described as an example of a device for executing a form control method, where the interactive smart tablet is an integrated device that controls content displayed on a display tablet and implements human-computer interaction operations through a touch technology, and integrates multiple functions of a projector, an electronic whiteboard, a curtain, a sound, a television, a video conference terminal, and the like. Referring to fig. 1, the table control method provided in this embodiment includes:

and S110, displaying the standard form generated based on the handwriting form track on a display screen.

In this embodiment, the display screen is a touch display screen. The user can write, control and the like on the display screen through a finger or an associated intelligent pen. Specifically, the electronic whiteboard function is set, a user can write in the display screen after starting the electronic whiteboard function, and the interactive intelligent panel records the writing track generated based on the writing operation in real time. The writing track is obtained by arranging a series of touch points according to a writing time sequence. Therefore, when writing tracks are recorded, the time stamps of the touch points in the writing tracks are synchronously recorded.

Further, when it is confirmed that the user stops writing, all writing tracks are recognized to confirm whether the writing tracks are handwritten form tracks, if the writing tracks are handwritten form tracks, the handwritten form tracks are shaped to obtain standard forms, the handwritten form tracks are replaced by the standard forms in the display screen, and if the writing tracks are not the handwritten form tracks, the writing tracks are continuously displayed in the display screen. The manner of determining that the user stops writing may be: determining that the user stops writing when the user clicks a set ending key in the display screen; the method can also be as follows: and within the set time length, if the writing track input by the user is not received, determining that the user stops writing. The above-mentioned handwritten form trajectories are not reshaped trajectories.

Specifically, the manner of determining whether the writing track is the handwriting form track may be: identifying whether the writing track is a cross graph or a suspected table graph formed by at least two transverse lines and at least two vertical lines, and if so, determining that the writing track is a handwritten table track; it can also be: setting a form writing mode, and when a user starts the form writing mode, defaulting a writing track as a handwriting form track; the method can also be as follows: and prompting the user to define a track area, and determining all writing tracks in the defined area in the display screen as handwriting form tracks.

Typically, the manner of integrating the handwriting table trace to obtain the standard table is as follows: peripheral rectangular coordinates of the table are determined based on boundary points of the handwritten table tracks, the row number, column number, cell number and the like of the table are determined according to intersection points among the handwritten table tracks, and then the corresponding standard table is drawn according to the data. Optionally, machine learning is performed on a large number of existing standard forms to establish a shaping model, writing tracks are input into the shaping model, whether the writing tracks are handwriting table tracks or not is determined through the shaping model, and if the writing tracks are the handwriting table tracks, the shaping model automatically draws the standard forms.

When the standard form is drawn, the width and the height of each cell in the standard form may be set to be the same, for example, fig. 2 is a schematic diagram of a first display interface of a display screen, as can be seen from fig. 2, a track of a handwritten form displayed in the display screen includes four horizontal lines and four vertical lines, and further, the track of the handwritten form is shaped according to the above mentioned manner, and the standard form with the same width and height of each cell is obtained. FIG. 3 is a diagram of a second display interface of the display screen. The standard form having the same width and height of each cell obtained based on the handwritten form trace in fig. 2 is displayed in the display interface in fig. 3. The width and height of each cell in the standard form can also be set to be determined according to the distance between corresponding handwritten form tracks. For example, fig. 4 is a schematic diagram of a third display interface of the display screen, and the display interface of fig. 4 displays a standard form obtained based on the handwritten form tracks in fig. 2, where the width and height of each cell are different according to the distance between the corresponding handwritten form tracks.

It should be noted that the standard table mentioned above is a machine drawn table, similar to a table displayed in Excel or a table inserted in Word, and the number of columns corresponding to different rows may be different, and the number of rows corresponding to different columns may also be different.

And S120, adjusting corresponding cells in the standard table based on the touch operation of the user on the standard table in the display screen.

Illustratively, after the standard form is displayed, the writing track of the user is continuously obtained and recognized, and if the writing track is recognized as the text track, the print text data of the text track is displayed in the cell where the writing track is located. And if the writing track is not recognized as the text track, confirming that the writing track is the touch operation of the corresponding cell in the adjustment standard form. Wherein, adjusting the cell includes: adjusting at least one of column width of the cells, adjusting row width of the cells, merging the cells, splitting the cells, modifying background parameters of the cells, deleting display data in the cells, and changing display parameters of the display data in the cells. Specifically, the touch operations corresponding to the above items are preset when the cell is adjusted. When the touch operation executed by the user based on the standard table is acquired, the adjustment item corresponding to the touch operation and the cell to be adjusted are identified, and then the cell to be adjusted is correspondingly adjusted. The specific setting mode and the setting content of the touch operation can be set according to actual conditions, at the moment, due to the touch attribute of the display screen, the adjustment mode can be flexible and changeable when the cell is adjusted, and compared with a table in Excel or Word, the adjustment mode can be simpler.

Optionally, when a save instruction of the user is detected, the standard table is saved as editable data in the set format. The execution mode of the save instruction is not limited in this embodiment. For example, when it is detected that the current display interface is closed, it is determined that a save instruction is received and the standard form is saved as editable data in the set format, or when it is detected that a save key is clicked, it is determined that a save instruction is received and the standard form is saved as editable data in the set format.

According to the technical scheme provided by the embodiment, the handwriting form track of the user is shaped into the standard form to display the standard form in the display screen, and the shaping of the handwriting form track is realized under the electronic whiteboard function based on the technical means that the user adjusts the corresponding cell in the standard form by the touch operation of the user on the standard form, the adjustment of the standard form can be realized by the way of touching the standard form of the display screen, particularly in a conference scene, when the user needs to draw the form, the standard form data can be obtained without additionally starting form drawing software, and the use experience of the user is improved.

Example two

Fig. 5 is a flowchart of a table control method according to a second embodiment of the present invention. The present embodiment is embodied on the basis of the above-described embodiments. Referring to fig. 5, the table control method provided in this embodiment specifically includes:

s201, recording a handwritten form track written in a display screen by a user in real time.

In this embodiment, the current writing tracks of the user are all set as the handwriting table tracks by default. Specifically, when the user writes in the writing track, the interactive intelligent tablet determines the position of each touch point in the writing track and the corresponding timestamp. Specifically, the track identifications of the handwriting form track obtained by writing in by the user are different from the track identifications of the standard tracks in the standard form obtained by shaping, and the handwriting form track and the standard tracks in the display screen can be distinguished by the interactive intelligent tablet through the track identifications.

In practical applications, only a part of the writing tracks in the display screen may be the handwritten form tracks, and the rest of the writing tracks are used for displaying other contents input by the user. The distinguishing mode can be as follows: and setting a table writing mode, and when the table writing mode is started, setting the writing tracks obtained before the default table writing mode is started and the user stops writing all as the handwriting table tracks.

And S202, when the user stops writing, determining the attribute information of the standard form based on all the currently recorded handwritten form tracks.

In this embodiment, it is determined that the user lifts his hand and stops writing if the handwritten form trace input by the user is not detected within the set time period. The set time length can be set according to actual conditions, such as 1 minute, 2 minutes and the like.

Further, a shaping model is set, after all handwritten form tracks recorded at present are input into the shaping model, the shaping model judges whether the handwritten form tracks can form a form or not according to the position points and the time stamps of all the handwritten form tracks, if the handwritten form tracks can form the form, attribute information of the form is determined, wherein the attribute information comprises peripheral matrix coordinates, line numbers, column numbers, cell numbers, positions of all edges in the form, background parameters of the cells and the like. The sidelines are row sidelines and column sidelines in the standard table. Specifically, a rectangle surrounding each edge of the handwritten form track is determined, and the rectangle is shaped to determine peripheral matrix coordinates. Furthermore, the number and the position of the row edge and the column edge inside the rectangle are determined, and further the number of rows, the number of columns, the number of cells, the position of each edge in the table and the like are determined. Because the handwritten form trajectories entered by the user during writing may not be standard, such as the handwritten form trajectories shown in FIG. 2, where some handwritten form trajectories are not smooth straight lines and some handwritten form trajectories are not horizontal or vertical axes. Therefore, in order to accurately draw the standard table, an error range may be set, and when the handwritten table trajectory is within the error range, the handwritten table trajectory is defaulted as the valid trajectory. In general, the standard table obtained by the shaping model only contains row edges and column edges, and does not contain oblique edges.

And S203, deleting the handwritten form track in the display screen, and displaying the corresponding standard form in the display screen based on the attribute information.

Specifically, the embodiment of the present invention is not limited to the specific way of deleting the handwritten form tracks, for example, all the handwritten form tracks are deleted simultaneously, or the handwritten form tracks are deleted sequentially according to the time stamp. Deleting the handwritten form track and displaying the standard form may be performed simultaneously or sequentially. The specific way of displaying the standard table is not limited in this embodiment. For example, all cells in the standard table are displayed simultaneously.

In general, a standard form may be considered a redrawn trace based on a handwritten form trace, since a trace may be erased unintentionally by the user. For example, when a user erases display data of a certain cell by using the electronic eraser, the border of the cell is erased unintentionally, and at this time, the interactive smart tablet is set to repair the cell by itself, so as to ensure the integrity of the border of the cell. For example, when the interactive smart tablet detects that the border of the cell is erased by the electronic eraser in synchronization with the display data in the cell, the erased border is recorded and the erased border is displayed again after the erasing is finished.

And S204, recording the attribute information corresponding to the standard table in the attribute comparison table.

In order to facilitate management statistics of the standard table, an attribute comparison table is set for the standard table. Wherein, each standard table corresponds to an attribute comparison table. The storage position and the naming format of the attribute comparison table can be set according to actual conditions. Further, the attribute comparison table records the standard table position, the cell position and the attribute information corresponding to each cell. When the interactive intelligent tablet wants to search a certain cell, the position, the attribute information and the like of the cell can be determined only according to the attribute comparison table.

S205, detecting touch operation input by a user in the display screen.

For example, when the writing track is determined to be a touch operation, the touch operation is analyzed, wherein a specific analysis manner of the touch operation may be set according to an actual situation. Specifically, the corresponding adjustment item is determined according to the touch operation, which specifically includes:

s206, if the initial position of the user inputting the touch operation in the display screen is overlapped with the vertex position of any vertex in the standard table, zooming the standard table according to the touch operation. S212 is performed.

Specifically, the outline shape of the standard table drawn in this embodiment is a rectangle, which includes 4 vertices. And if the starting position is determined to coincide with the vertex position corresponding to any vertex in the standard table, determining to execute the operation of scaling the standard table. Further, if the touch operation moves towards the inside of the standard table based on the initial position, the standard table is determined to be reduced, and the vertex is controlled to coincide with the current position point of the touch operation in real time so as to reduce the standard table in real time. And if the touch operation moves to the outside of the standard table based on the initial position, determining to enlarge the standard table, and controlling the vertex to coincide with the current position point of the touch operation in real time so as to enlarge the standard table in real time.

Optionally, in order to prevent the misoperation condition, a first pressing time length is set, and if the coincidence time of the starting position and the vertex position exceeds the first pressing time length, the scaling standard table operation is determined to be executed. For example, after the standard table is displayed on the display screen, if it is determined that a user presses within a certain point, the point is coincident with a vertex position of the standard table, and the coincidence time exceeds a first pressing duration, it is determined that a touch operation is received, and the touch operation is used for zooming the standard table. Further, after the pressing duration is exceeded, the vertex is controlled to coincide with the current position point of the touch operation in real time, so that the standard table scaling is realized.

And S207, if the initial position of the touch operation input by the user in the display screen is overlapped with the intersection point position of any cell intersection point in the standard table, moving the edge line containing the cell intersection point according to the touch operation to adjust the first cell containing the edge line. S212 is performed.

The cell intersection points refer to other intersection points except for 4 vertexes in the standard table. Taking the standard table in fig. 3 as an example, the standard table includes 12 cell intersections. Specifically, if the intersection point position of the initial position and the intersection point of any cell in the standard table is determined to be coincident, the boundary line where the intersection point is adjusted is determined, wherein the boundary line is a row boundary line and/or a column boundary line. In general, each intersection corresponds to a row edge and a column edge. The row borderline refers to a borderline on the same horizontal axis corresponding to a row of cells, i.e. a row of cells includes two row borderlines. The column borderline refers to a borderline on the same vertical axis corresponding to a column of cells, that is, a column of cells includes two column borderlines. Optionally, in order to prevent the misoperation, a second pressing duration is set, and if the coincidence time of the starting position and the vertex position exceeds the second pressing duration, the operation of moving the sideline is determined to be performed.

When the edge is adjusted, the size of the first cell containing the edge changes. The adjustment range is related to the current position point of the touch operation. Specifically, moving the edge including the intersection point of the cell according to the touch operation includes the following steps:

s2071, determining a connection line between the current touch position and the start position of the touch operation.

Optionally, the connection line may be selectively displayed on the display screen according to actual conditions.

And S2072, determining the moving direction according to the included angle of the axis where the intersection point of the connecting line and the cell is located, wherein the axis comprises a horizontal axis and/or a vertical axis.

Specifically, taking a horizontal axis as an example for exemplary expression, a line edge line including an intersection point of the cells is the horizontal axis. Further, an included angle between the connecting line and the horizontal axis is calculated, and the moving direction of the intersection point of the cells is determined according to the included angle. And the moving directions corresponding to different included angle ranges are preset, and then the moving directions corresponding to the included angles are determined according to the included angle ranges where the included angles are located. This has the advantage of preventing the user from being able to accurately adjust the first cell at an angle. For example, the user wants to move the line edge upward, but in actual operation, the user may not be able to ensure that the cell intersection point selected in the line edge moves vertically upward, and therefore, setting the included angle range may reduce the accuracy of the user operation.

The moving directions corresponding to different included angle ranges can be according to actual conditions. For example, fig. 6 is a schematic view of the first angle range. Wherein, the included angle range is determined according to the horizontal axis 21, and when the included angle falls into the included angle range A, the moving direction is determined to be the right movement. And when the included angle falls into the included angle range B, determining the moving direction as upward movement. And when the included angle falls into the included angle range C, determining that the moving direction is leftward movement. And when the included angle falls into the included angle range D, determining the moving direction as downward movement. For another example, fig. 7 is a schematic diagram of the second angle range. Wherein, the included angle range is determined according to the horizontal axis 22, and when the included angle falls into the included angle range E, the moving direction is determined to be moving rightwards. And when the included angle falls into the included angle range F, determining that the moving direction is moving towards the upper right direction. And when the included angle falls into the included angle range G, determining the moving direction as upward movement. And when the included angle falls into the included angle range H, determining that the moving direction is moving towards the upper left direction. And when the included angle falls into the included angle range I, determining that the moving direction is leftward movement. And when the included angle falls into the included angle range J, determining that the moving direction is moving towards the left lower direction. And when the included angle falls into the included angle range K, determining the moving direction as downward movement. And when the included angle falls into the included angle range L, determining that the moving direction is moving towards the right lower direction.

It should be noted that, when the axis is a vertical axis, or a horizontal axis and a vertical axis, the moving direction determining manner is the same as that of the horizontal axis, and details are not described herein.

S2073, calculating a distance between the current touch position and the start position.

Wherein, the distance includes a horizontal distance and/or a vertical distance, which can be represented by the number of pixel points. For example, the number of pixel points spaced in the horizontal direction between the current touch position and the initial position is determined to obtain the horizontal distance. And determining the number of pixel points at the interval of the current touch position and the initial position in the vertical direction to obtain the vertical distance. If the current touch position and the starting position are on the same horizontal axis, the distance only comprises the horizontal distance, and if the current touch position and the starting position are on the same vertical axis, the distance only comprises the vertical distance.

In order to reduce the amount of computation in calculating the distance, specific contents included in determining the distance according to the moving direction are set. For example, when the moving direction is upward movement, only the vertical distance needs to be calculated. When the moving direction is rightward, only the horizontal distance needs to be calculated. When the moving direction is moving upward to the left, the horizontal distance and the vertical distance need to be calculated.

S2074, selecting an edge line according to the moving direction, and moving the selected edge line according to the distance.

Specifically, when the moving direction is moving upward or moving downward, the corresponding borderline is a line borderline. When the moving direction is left moving or right moving, the corresponding edge line is a column edge line. The moving direction is other directions, such as an upper left direction, a lower right direction, and the like, and the corresponding edge lines are a row edge line and a column edge line. Optionally, in the touch process, the interactive smart tablet adjusts the corresponding edge line in real time according to the current touch position.

For example, setting the moving direction and the included angle range refers to fig. 7. Fig. 8 is a schematic diagram of a fourth display interface of the display screen, in which the cell intersection Z coincides with the start position and the coincidence time exceeds a second set duration. Further, if the current touch position is a point Y, an included angle between a connecting line of the point Z and the point Y and a row edge line 23 where the point Z is located is calculated, and the moving direction is determined to be upward according to the range of the included angle. Further, the vertical distance between the Z point and the Y point is calculated, and the line edge 23 including the Z point is moved upward according to the vertical distance. Fig. 9 is a schematic diagram of a fifth display interface of the display screen, and it can be seen from fig. 9 that after the Z point moves, the size information of the first cell 24 containing the row edge 23 changes. If the current touch position is W point, calculating the included angle between the connecting line of Z point and W point and the line side line 23 where Z point is located, and determining the moving direction to be the right-lower direction moving according to the included angle range where the included angle is located. Further, the vertical distance and the horizontal distance between the Z point and the W point are calculated, the row edge line 23 including the Z point is moved downward according to the vertical distance, and the column edge line 25 including the Z point is moved rightward according to the horizontal distance. Fig. 10 is a schematic diagram of a sixth display interface of the display screen, and it can be seen from fig. 10 that after the Z point moves, the size information of the first cell 26 including the row edge 23 and the column edge 25 changes.

And S208, if the initial position of the touch operation input by the user in the display screen is positioned on the frame line of any cell and is fixed within the set time length, moving the frame line according to the touch operation to adjust a second cell containing the frame line. S212 is performed.

Wherein, a unit cell contains 4 frame lines, and any two adjacent unit cells share 1 frame line. Each edge line is composed of a certain number of edge frame lines. For example, referring to the standard table in FIG. 4, each edge contains 3 edge frame lines. Furthermore, each border line comprises two end points, and the starting position on the border line means that the starting position is located at a position other than the end points in the border line. Further, in order to prevent the erroneous operation situation, a time period is set in advance, and if the stay time of the start position on the frame wire exceeds the time period, it is determined that the operation of moving the frame wire is performed. Wherein the set time length is a third set time length.

Specifically, if the frame line is a vertical frame line and the current touch position is on the left side of the start position, it is determined to move the vertical frame line to the left, and the horizontal distance between the current touch position and the start position is calculated to move the frame line to the left according to the horizontal distance. Moving the border wire to the right is similar to moving the border wire to the left and will not be described further herein. If the frame line is a horizontal frame line and the current touch position is above the initial position, determining to move the horizontal frame line upwards, and calculating the vertical distance between the current touch position and the initial position to move the frame line upwards according to the vertical distance. The manner of moving the border wire downward is similar to the manner of moving the border wire upward, and is not described in detail herein. Generally, the bezel wire can only move in the vertical direction or the horizontal direction. It should be noted that the distance calculation method mentioned above is the same as the distance calculation method described in S2073, and is not described herein again.

For example, the display interface of the display screen is shown in fig. 8. Further, the corresponding frame line 27 is determined according to the starting position P, and the current touch position Q is above the frame line 27, at this time, the vertical distance between the point Q and the point P is calculated, and the frame line 27 is moved. Fig. 11 is a schematic diagram of a seventh display interface of the display screen, and it can be seen from fig. 11 that after the frame line 27 moves to the point P, the size information of the second cell 28 including the point P changes.

And S209, if the starting position and the end position of the touch operation input by the user in the display screen are positioned in different cells, merging all the third cells through which the touch operation passes. S212 is performed.

Specifically, a cell where the starting position is located and a cell where the end position is located are determined, each cell included in the horizontal direction between the two cells and each cell included in the vertical direction are determined, each included cell is marked as a third cell, and then all the third cells are merged. The touch track corresponding to the touch operation is preferably a straight line or a curved line.

Illustratively, the step specifically includes:

s2091, calling an editable operation line.

Specifically, the operation line is a straight line capable of adjusting the position of the end point. The method for retrieving the operation line is not limited in this embodiment, for example, a tool box of the operation line is displayed in the display screen, and when it is determined that the tool box is selected, the operation line is displayed in the display screen. Preferably, the operating line is displayed outside the standard table.

And S2092, adjusting the operation line based on the touch operation input by the user in the display screen.

Furthermore, the user adjusts the positions of the two end points of the operation line through touch operation. For example, when a certain endpoint is clicked and dragged by a user, the endpoint is synchronously moved according to the dragging of the user.

S2093, determining a third cell through which the adjusted operation line passes, and merging the third cell.

For example, one end of the operation line is located in cell a, the other end is located in cell b, and the merged cell is h. Assuming that the row occupied by the cell a is the 1 st row, the 1 st column and the row occupied by the cell b is the 1 st row and the 2 nd column, the row occupied by the cell h is the 1 st row, the 1 st column and the 2 nd column; assuming that the row occupied by the cell a is the 1 st row and the 1 st column, and the row occupied by the cell b is the 2 nd row and the 1 st column; the row occupied by the cell h is the 1 st and 2 nd rows and the 1 st column; assuming that the row occupied by the cell a is the 1 st row and the 1 st column, and the row occupied by the cell b is the 2 nd row and the 2 nd column; the row occupied by cell h is row 1, 2 and column 1, 2. Fig. 12 is a schematic diagram of an eighth display interface of the display screen, and referring to fig. 12, assuming that the cell a is located in the first column of a certain row and the cell b is located in the last column of the row, the cell h merged by the operation line includes all columns of the row, and at this time, the display interface of the display screen refers to fig. 13.
