Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The method for selecting the adsorption element of the rotary element provided by the invention can be applied to an application scene shown in fig. 1, fig. 1 is an application scene schematic diagram of the method for selecting the adsorption element of the rotary element in one embodiment, the application scene can include intelligent interactive equipment, such as a computer, a tablet or an interactive intelligent tablet, and the like, wherein the interactive intelligent tablet can be integrated equipment for controlling content displayed on a display tablet of the interactive intelligent tablet through a touch technology and realizing man-machine interactive operation, and the interactive intelligent tablet integrates one or more functions of a projector, an electronic whiteboard, a curtain, a sound, a television, a conference terminal and the like. In the specific application of the intelligent interactive device, a user can edit scene elements related to various applications such as teaching courseware making software and the like installed on the intelligent interactive device.

Taking the interactive intelligent tablet 100 as an example to illustrate an application scene, the interactive intelligent tablet 100 can display scene elements in an application such as teaching courseware making software through the display tablet 110, enabling the user to pan, add, delete, etc. the displayed scene elements on the display tablet 110, for example, the user needs to rotate the rotation point R to the scene point P, the interactive smart tablet 100 can determine the rotation center D thereof according to the rotation point R designated by the user to perform the rotation operation on the rotation point R, however, in the process of rotating the rotation point R to the scene point P, the conventional element operation mode of the interactive smart tablet 100 requires the user to perform multiple position adjustments on the rotation point R near the position near the scene point P before rotating the rotation point R to the position of the scene point P, which results in low operation efficiency on each scene element.

It should be noted that, the problem of low operation efficiency also exists when other elements are rotated, and the rotation of the rotation point R to the scene point P is only one example for explaining the technical problems existing in the conventional element operation mode.

In an embodiment, a method for selecting a chucking element of a rotating element is provided, and referring to fig. 2, fig. 2 is a flowchart illustrating a method for selecting a chucking element of a rotating element in an embodiment, which may be applied to the interactive smart tablet 100 shown in fig. 1, where the method for selecting a chucking element of a rotating element may include the following steps:

step S101, selecting a rotation element and determining the rotation center of the rotation element.

The rotation element refers to an element used for performing a rotation operation in a scene, the scene refers to an area used for carrying scene elements, and various scene elements such as a point element and a line element can be displayed in the scene, wherein the line element can be a line element such as one side of a triangle or a ruler side; the rotation center is a rotation center when the rotation element is rotated, and for example, when the rotation element is rotated in a circular manner, the rotation center corresponds to a center of a circle.

In this step, the user may select a rotation element from the plurality of scene elements displayed by the interactive smart tablet 100, or may use a scene element newly added to the scene as the rotation element, and the interactive smart tablet 100 may select the element selected by the user as the rotation element and determine the rotation center thereof.

Step S102, position information of the rotation element and the rotation center is acquired.

The method mainly comprises the steps that after the interactive intelligent panel 100 selects a rotating element and determines the rotating center of the rotating element, the position information of the rotating element and the rotating center of the rotating element is obtained; the position information refers to position information of the rotation element and the rotation center in the scene, for example, coordinates of the rotation element in the scene, coordinates of the rotation center in the scene, or a relative position relationship between the rotation element and the rotation center.

In step S103, the suction area of the rotation element is calculated from the position information of the rotation element and the rotation center.

Here, the attraction means that the magnetic material is attracted as a magnet when the magnetic material is close to the target position. Taking the rotation point in fig. 1 as an example, assuming that the target position is the position of the scene point P, when the rotation point R rotates close to the scene point P, the user wants the rotation point R to be absorbed by the scene point P. The adsorption region refers to a region in the scene that can be used for adsorption by a specific scene element, and the adsorption region of the rotation element refers to a region in the scene that can be used for adsorption by the rotation element.

In this step, the interactive smart tablet 100 may calculate an adsorption area of the rotation element according to the position information of the rotation element and the rotation center thereof, where the adsorption area is mainly used to define a selection range for selecting the adsorption element for the rotation element, for example, the adsorption area may include an area through which the rotation element passes in the rotation process, and the area may be calculated according to a relative distance between the rotation element and the rotation center.

Step S104, selecting adsorption elements of the rotation elements from the scene elements according to the adsorption areas.

Since the scene elements are usually distributed in different positions of the scene, the interactive smart tablet 100 mainly selects a specific scene element from the scene elements as the adsorption element of the rotation element according to the adsorption area obtained in step S103.

In general, the interactive smart tablet 100 may select an adsorption element according to the degree of overlap of the scene element with the adsorption area, for example, the scene element located in the adsorption area is used as the adsorption element of the rotation element. The scene elements refer to elements that can be adsorbed by the rotation elements in the scene elements, and include elements of points or lines, one scene element may include a plurality of points and lines, and the adsorption element may adsorb the points or lines in the elements, taking a scene formed by a two-dimensional plane as an example, these scene elements are scene elements that do not move on the two-dimensional plane, and may be elements that the rotation elements adsorb, such as one side of a triangle in the two-dimensional plane, and the rotation element may be a scale line of the ruler, and one side of the triangle may be used for the scale line of the ruler to adsorb.

The method for selecting an adsorption element of a rotary element according to the embodiment includes selecting the rotary element and determining a rotation center of the rotary element, obtaining position information of the rotary element and the rotation center, calculating an adsorption area of the rotary element according to the position information, and selecting the adsorption element from scene elements based on the adsorption area, so that the adsorption element of the rotary element can be selected when the rotary element is rotated, and the adsorption element can be used for adsorption when the rotary element is rotated, so that the rotary element can be rapidly rotated to the position of the adsorption element in the rotation process, thereby overcoming the problem that the rotary element needs to be adjusted for multiple times in the conventional technology, and improving the operation efficiency of the rotary element.

In one embodiment, the step of determining the adsorption area of the calculation rotation element according to the position information of the rotation element and the rotation center in step S103 may include:

calculating a rotation path of the rotation element according to the position information of the rotation element and the rotation center; and determining the adsorption area of the rotating element according to the rotating path.

In this embodiment, the rotation path refers to a motion trajectory formed in the rotation process, the rotation path of the rotation element refers to a motion trajectory that the rotation element passes through when rotating in the scene, and the rotation path may be displayed through the display panel 110 after being calculated by the interactive smart panel 100, so that the rotation path is more intuitive and has a higher visualization degree.

The interactive smart tablet 100 may obtain the position information, such as the relative distance, of the rotation element and the rotation center in real time, calculate the rotation path of the rotation element according to the position information, and determine the adsorption area of the rotation element according to the rotation path. The rotation path may be set as an adsorption region, and the adsorption region is displayed through the display panel 110, so that a user can visually see the position of the adsorption region, which is beneficial to further selecting the adsorption element.

In an embodiment, the step of determining the adsorption area of the rotating element according to the rotation path in the above embodiments may further include:

acquiring a set path error value; and setting the adsorption area of the rotating element according to the path error value and the rotation path.

In this embodiment, the path error value refers to an error value allowed for the rotation path, and the setting of the path error value is to take into account that when the rotation element is rotated, the rotation path is likely to have a certain deviation from the path desired by the user.

The interactive smart tablet 100 may set an adsorption area of the rotation element according to a path error value and a rotation path, for example, widen a line identifying the rotation path according to the path error value, which is beneficial to improve a fault tolerance of the rotation path through the path error value in the rotation process of the rotation element, and more accurately adsorb the rotation element to a scene element that a user desires to adsorb to, where the path error value may be set according to a screen size of the interactive smart device 100, and the calculation method may be that the screen size is divided by 375.

In one embodiment, the step of selecting the adsorption element of the rotation element from the scene elements according to the adsorption area in step S104 may include:

setting the scene elements in the adsorption area as alternative elements; determining a rotation direction of the rotation element; and selecting adsorption elements from the alternative elements according to the rotation direction.

The candidate elements refer to scene elements located in the adsorption region, and the scene elements located in the adsorption region are not limited to scene elements completely falling into the adsorption region, and may also be scene elements having a certain overlap region with the adsorption region; the rotation direction refers to the motion of the rotation element when performing a rotation operation in the scene, and the rotation direction includes clockwise and counterclockwise directions, taking the circular rotation as an example.

The interactive smart tablet 100 may acquire scene elements located in the adsorption area, set the scene elements as alternative elements, acquire a moving direction of the rotation element during the rotation process as a rotation direction of the rotation element, and select an adsorption element from the alternative elements according to the rotation direction.

In this embodiment, it is mainly considered that when a user rotates a rotating element, the rotating element may be rotated in a certain direction, for example, the rotating element is rotated in a counterclockwise direction, an element that is adsorbed and matched with the counterclockwise direction may be selected from the candidate elements as an adsorbing element, which is beneficial for the rotating element to rotate and adsorb to a position of the adsorbing element quickly, however, if a clockwise candidate element is selected, the rotating and adsorbing operation of the rotating element by the user may be affected, and the rotating element is easily adsorbed to a reverse scene element, so that the user needs to re-adsorb the rotating element, which not only reduces the operation efficiency, but also reduces the user experience.

In an embodiment, the step of selecting the adsorption element from the candidate elements according to the rotation direction in the above embodiments may further include:

determining the rotation angles of the alternative elements and the rotation elements according to the rotation direction of the rotation elements; and selecting adsorption elements from the alternative elements according to the rotation angle.

The rotation angle of the alternative element and the rotation element is an included angle formed by the alternative element, the rotation center and the rotation element.

The interactive smart tablet 100 may sequentially determine a rotation angle formed between the plurality of candidate elements and the rotation element according to the rotation direction of the rotation element, and select an adsorption element in each of the candidate elements according to the rotation angle. Considering that each alternative element and the rotating element actually form a plurality of included angles, alternative elements corresponding to certain specific included angles may not be suitable for being used as adsorption elements, the scheme of the embodiment can improve the selection efficiency and accuracy of the adsorption elements.

In addition, the interactive smart tablet 100 may further display the candidate elements and the corresponding included angles thereof through the display panel 110, provide the user with a selection, and select the candidate elements that need to be used as the adsorption elements.

In an embodiment, further, the step of selecting the adsorption element from the candidate elements according to the rotation angle in the above embodiments may include:

comparing the rotation angle with a set adsorption angle threshold value; and if the rotation angle is smaller than the adsorption angle threshold value, selecting an adsorption element from the candidate elements.

In this embodiment, the adsorption angle threshold refers to an angle threshold for screening the rotation angle.

The interactive smart tablet 100 may obtain an adsorption angle threshold preset by the user, compare the rotation angle of each candidate element and the rotation element with the adsorption angle threshold, and select an adsorption element from the candidate elements corresponding to the rotation angle if the rotation angle is smaller than the adsorption angle threshold.

Considering that an included angle formed by some candidate elements and the rotation element is too large among the multiple candidate elements, it is described that the distance between the candidate elements and the rotation element on the rotation path is far and is not suitable for being used as an adsorption element, so that the adsorption element is selected from the candidate elements of which the rotation angle is smaller than the adsorption angle threshold value in the technical scheme of the embodiment, which is beneficial to improving the selection efficiency and accuracy of the adsorption element.

In addition, the interactive smart tablet 100 may further display the selected adsorption elements and the rotation angles corresponding to the selected adsorption elements in a list form through the display tablet 110, so that the selected adsorption elements are displayed more intuitively, and user experience is improved.

In one embodiment, the rotation element is a rotation point; the step of calculating the adsorption area of the rotation element from the position information of the rotation element and the rotation center in step S103 may include:

calculating the distance between the rotation point and the rotation center according to the position information of the rotation point and the rotation center; calculating the rotation circumference of the rotation point according to the distance between the rotation point and the rotation center; and determining the adsorption area of the rotation point according to the rotation circle.

The present embodiment mainly calculates the adsorption area of the rotation point in the case where the rotation element is the rotation point. Referring to fig. 3(a), fig. 3(a) is a schematic diagram of a scene position reference of a rotation point and a scene point in an embodiment, where the scene includes a rotation point R, a rotation center D, and a plurality of scene point elements P, where a scene point element P is a point element in a scene element; the rotation circle C refers to a circle formed by the rotation point R when rotating.

The interactive smart tablet 100 may calculate the distance between the rotation point R and the rotation center D according to the coordinates of the rotation point R and the rotation center D, for example, the coordinate of the rotation point R is (x)₁,y₁) The coordinate of the rotation center D is (x)₂,y₂) The distance D between the rotation point R and the rotation center D can be expressed as

The rotation circle C of the rotation point can be calculated from the distance D, and then the rotation circle C can be set as the adsorption region of the rotation point R, and in addition, in the actual calculation, it is necessary to perform a plurality of opening calculations in consideration of the calculation of the distance, and the calculation of the distance D is intended to determine the relative distance between two points, so in order to reduce the number of opening calculations and improve the calculation efficiency, the square of the distance D can be used to correspond to the distance between the rotation point R and the rotation center D.

In one embodiment, the step of selecting the suction element of the rotation element from the scene elements according to the suction area in step S104 may further include:

determining scene point elements in the scene elements and acquiring position information of the scene point elements; calculating the distance between the scene point element and the rotation center according to the position information of the scene point element and the rotation center; determining scene point elements in the adsorption area according to the distance between the scene point elements and the rotation center; the adsorption element of the rotation point is selected from the scene point elements in the adsorption area.

In the embodiment, after a rotation circle of a rotation point is determined, scene point elements belonging to point elements are determined in the scene elements, and adsorption elements are selected from the scene point elements; wherein the position information of the scene point elements comprises position coordinates of the scene point elements.

According to the position coordinates of each scene point element and the rotation center, the distance d between each scene point element and the rotation center can be respectively calculated through the following distance formula:

wherein the coordinates of the scene point elements may be represented as (x)₁,y₁) The coordinates of the center of rotation may be expressed as (x)₂,y₂) Considering that a large number of scene point elements may exist in the scene, the square of the distance may be corresponding to the distance d between each scene point element and the rotation center, so that many times of evolution operations can be reduced, and the calculation efficiency is improved.

Whether the scene point element is located in the adsorption area can be determined according to the distance d between the scene point element and the rotation center, if the deviation value between the distance between the scene point element and the rotation center and the radius of the rotation circle C is large, the scene point element is considered not to be the scene element located in the adsorption area, and the scene element can be excluded, in this way, all the elements with large deviation value with the radius of the rotation circle C can be excluded, the rest scene point elements are the scene elements in the adsorption area, as shown in fig. 3(b), fig. 3(b) is another scene position reference diagram of the rotation point and the scene point in one embodiment, and the scene element in the adsorption area corresponds to the scene point element P in fig. 3(b)₁、P₂、P₃、P₄And P₅。

Further, scene point element P may be traversed₁、P₂、P₃、P₄And P₅Taking the nth element P_nIs connected to P_nAnd the center of rotation D, and the point of rotation R and the center of rotation D as two vectors

And

And

angle P of_αIf the included angle P is satisfied_αLess than the set adsorption angle threshold α, then P may be set_nPut into alternative element set P_dIn (1).

Optionally, when the rotation direction of the scene point element is counterclockwise, considering that the scene point element with the same absorption direction and rotation direction needs to be selected, as shown in fig. 3(b), the rotation direction may be other than P₁Set P of all other alternative elements_dThe scene point elements in (1) are excluded because the rotation angle formed by the scene point elements with the rotation point is too large, or the adsorption direction is opposite to the rotation direction of the rotation point although the angle is small, and the exclusion of the scene point elements is beneficial to improving the selection efficiency of the adsorption elements.

Specifically, the scene point elements satisfying the rotation angle in the candidate elements may be selected in the following calculation manner:

the value resulting from the cross product operation is greater than 0, then the vector is derived
