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 specific embodiments and the accompanying drawings.
It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name but different names or different parameters, and it should be noted that "first" and "second" are merely for convenience of description and should not be construed as limitations of the embodiments of the present invention, and they are not described in any more detail in the following embodiments.
The embodiment of the invention provides an automatic adsorption method of interactive services, which is applied to an interactive device. The operator inputs information and operation commands through the terminal equipment (see the input and output system), the system immediately processes the information after receiving the information, and the processing result is displayed through the terminal equipment. The operator can further input information and operation commands according to the processing result. The present invention is not limited to the single interactive processing device, but may be applied to interactive applications such as interactive learning, and the following embodiments do not describe the present invention.
Further, in order to utilize an automatic absorption method in the interactive processing process, the flow chart manually made by the user on the screen or the electronic whiteboard is automatically absorbed into a complete graph, and in a specific application scenario, the interactive device at least comprises: interactive screens, interactive whiteboards, and interactive projection screens.
Fig. 1 is a schematic flow chart of an automatic absorption method for interactive services according to an embodiment of the present invention. The method specifically comprises the following steps:
This step is intended to acquire a target object selected by the user and the current position coordinates of this target object. There are many ways to obtain the user-selected target, such as: there are various ways to obtain the current position of the first object by using a click selection of a pointer, a gesture instruction selection of a finger, a voice instruction selection of a user, and the like, such as: the method comprises the steps of obtaining a coordinate set determining position of the whole target object, obtaining a coordinate determining position of a target central point, obtaining an endpoint coordinate determining position of the target object and the like, wherein different obtaining methods and modes for determining position information do not influence the protection scope of the invention as long as the corresponding purposes can be achieved.
Furthermore, time is saved in order to pick out qualified objects in advance from all the objects and pick out the overlapped positions of all the qualified objects according to the attribute of the first object, so that qualified position points can be found more quickly. In a preferred embodiment of the present application, the acquiring the first object selected by the user and the current position information of the first object specifically includes:
judging the current moving direction according to the position information and the previous position information of the first object before the preset time;
and screening out the qualified positions which can correctly complete the overlapping in all the objects according to the moving direction.
In a specific application scenario, firstly, in a general flowchart, selected objects mainly include two types of graphics: the first is a closed figure with an area consisting of at least one edge, such as: rectangular, diamond, parallelogram, circular arc rectangular, oval, wavy rectangular, etc. The second is a linear graph or a combination of a linear graph and an arrow-like graph, such as: horizontal lines, vertical lines, horizontal arrows, broken lines, broken line arrows, and the like. After a user selects a graph, reading a specific range of the graph, determining the current coordinate of the graph, determining the moving direction of the selected graph according to the change of the position coordinate relationship of the graph after the user moves the graph, and selecting all points suitable for combination according to the graph and the graph suitable for combination, for example: if the rectangular graph is selected and moved to the left, the transverse line or the transverse arrow or the broken line on the left side of the rectangle is preferentially selected as qualified objects, and the end points of the qualified objects close to the direction of the rectangle are selected as qualified positions.
And 102, calculating the distances between all the objects and the first object, and selecting a second object closest to the first object.
This step is intended to find the second object that is closest to the first object. There are many ways in which the distance can be calculated, for example: calculating the distance between the center dots of the two graphics, the distance between the closest points of the two graphics, the distance between the farthest points of the two graphics, etc. Different methods do not affect the protection scope of the invention as long as different distance obtaining modes can achieve corresponding purposes.
It should be noted that two kinds of graphics, namely, a closed box graphic and a linear graphic, are commonly present in a general flowchart, and in order to achieve the purpose of the flowchart itself, unnecessary operations caused by the combination of the two closed box graphics are avoided. In a preferred embodiment of the present application, at least one of the first object and the second object is a linear object.
Furthermore, in order to accurately select the nearest second object suitable for adsorption bonding, the accuracy in the selection process is increased, and the target object is quickly obtained. In a preferred embodiment of the present application, the calculating distances between all the objects and the first object, and selecting a second object closest to the first object specifically includes:
selecting the first qualified position according to the first object and the moving direction;
calculating the relative distance between the first qualified position and the qualified position;
and selecting the qualified position with the closest relative distance as the second qualified position, wherein the object corresponding to the second qualified position is the second object.
In a specific application scene, whether a linear graph or a closed frame graph is selected by a user is judged, meanwhile, points which can be adsorbed and bonded on the selected graph are determined according to the graph selected by the user and the moving direction of the current graph, then, the distance between the two points is calculated according to the coordinates of the points and the coordinates of all the points which are determined before and suitable for the points to be adsorbed and bonded, the closest points which are suitable for adsorption and bonding are selected, and a second object (the points are on the second object) is determined according to the points. For example: the user selects a transverse arrow, and the transverse arrow moves leftwards, so that the endpoint of the leftmost end of the transverse arrow is the first qualified position, then the distances between all qualified positions such as the endpoints of all vertical lines on the left side of the arrow, the midpoint or the rightmost endpoint of the rightmost edge of the closed block diagram graph, the endpoint of the vertical part of the broken line and the like and the first qualified position are respectively calculated, a point with the minimum distance is selected as a second qualified position, and the graph corresponding to the point is a second object.
This step is intended to determine whether the distance is within a certain range. There are various methods for determining whether the distance falls within the range, such as: directly obtaining an absolute distance value for judgment, obtaining a projection distance value for judgment and the like. Different judging methods can not influence the protection scope of the invention as long as the corresponding purpose can be achieved.
Further, in order to effectively read the operation intention of the user, the two objects are accurately adsorbed and bonded when the user drags the selected object within the proper range. In a preferred embodiment of the present application, the determining whether the distance between the first object and the second object is within a preset threshold specifically includes:
and judging whether the first qualified position falls within a preset threshold value on one side of the second qualified position.
It should be noted that, when the user drags the selected target to the adjacent position, the optimal suction range is set in consideration of the operation habit of the user in order to standardize the size of the specific suction range for automatic suction bonding. In a preferred embodiment of the present application, the preset threshold specifically is:
the second qualified position corresponds to a rectangular range surrounded by a line segment on the second object and a distance of 50 pixels from one side of the line segment relative to the first qualified position.
In a specific application scenario, after the first qualified position and the second qualified position are determined, the relative position relationship between the first qualified position and the second qualified position is determined, for example: the first qualified position is on the right of the second qualified position, and whether the first qualified position falls within a certain range on the right of the second qualified position is judged (a rectangular range is formed by two ends of the side where the second qualified position point is located and 50 pixels on the right side of the point).
And 104, if so, overlapping the first qualified position of the first object with the second qualified position of the second object.
This step is intended to overlap two sites to complete the adsorption bonding. There are many ways in which two suitable positions can be overlapped, such as: moving only the first object for overlapping, moving only the second object for overlapping, moving both objects simultaneously for overlapping in between, etc. Different overlapping modes can achieve the corresponding purpose, and different methods can not influence the protection scope of the invention.
Preferably, in order to prevent the already-made flow chart part from being damaged or deformed, the selection object of the user is made to the whole flow chart. In the preferred embodiment of the present application, during the overlapping process, only the first object is moved to overlap the first qualified position and the second qualified position, so as to ensure that the second object and the whole flowchart are not deformed by shifting.
By applying the technical scheme of the application, the scheme is that the first object selected by a user and the current position information of the first object are acquired; calculating the distances between all the objects and the first object, and selecting a second object closest to the first object; judging whether the distance between the first object and the second object is within a preset threshold value; and if so, overlapping the first qualified position of the first object with the second qualified position of the second object. By applying the technical scheme of the application, when a user drags one flow chart object and the other flow chart object to be combined by fingers, the user only needs to place the flow chart object to an approximate position, the method can automatically adsorb and align the flow chart objects according to the characteristics of the two flow chart objects, the use difficulty of the user is reduced, and the user experience is improved.
In order to further illustrate the technical idea of the present invention, the technical solution of the present invention will now be described with reference to specific application scenarios.
Before describing the application scenario, two major classes of flowchart objects need to be defined:
1. common flow chart objects such as circular arc rectangles, diamonds, parallelograms, sub-rectangles, circles or ovals, wavy rectangles, etc.
2. Connecting flowchart objects such as horizontal lines, vertical lines, horizontal arrows, vertical arrows, polylines, polyline arrows, and the like.
The method implements the following rules:
in the first case:
1. when the object to be moved is a circular arc rectangle, rhombus, sub-rectangle, wavy rectangle, ellipse, parallelogram, or the like, the object is set to be a.
2. And traversing all the flow chart objects on the current interface, and if the currently traversed objects are arrows or straight lines, setting the objects as B.
3. And judging the direction of B, if the direction is a vertical line, judging whether the top or the bottom of B is within a certain range of the bottom or the top of A. This range refers to the top range [ left, top-50, right, top +50] or the bottom range [ left, bottom-50, right, bottom +50] of A. If within this range, the adsorption is automatic.
4. Judging the direction of B, if it is a horizontal line, judging whether the left or right of B is in the right or left of A within a certain range, where the certain range is the left range [ left-50, top, left +50, bottom ] or the right range [ right-50, top, right +50, bottom ] of A. If within this range, the adsorption is automatic.
5. And traversing all the flow chart objects on the current interface, and if the currently traversed objects are broken line arrows or broken lines, setting the objects as C.
6. And judging the direction of C, if the direction is from top to bottom to right, and judging whether the top or the right of C can be automatically adsorbed with the bottom or the left of A according to the logic above.
7. And judging the direction of C, if the direction is from top to bottom to left, and judging whether the top or the left side of C can be automatically adsorbed with the bottom or the right side of A according to the logic above.
8. And judging the direction of the C, if the direction is from bottom to top to right, and judging whether the bottom or the right of the C can be automatically adsorbed with the top or the left of the A according to the logic above.
7. And judging the direction of the C, if the direction is from bottom to top to left, and judging whether the bottom or the left side of the C can be automatically adsorbed with the top or the right side of the A or not according to the logic above.
In the second case:
1. when the current moving object is an arrow or a straight line, the direction of the current object needs to be judged first, and if the current moving object is a vertical line, the current object is set as A; if the line is a horizontal line, the object is B.
2. And if the current object is A, traversing all the flow chart objects on the current interface, and if the current traversed object is a circular arc rectangle, a rhombus, a sub-rectangle, a wavy rectangle, an ellipse or a parallelogram, setting the object as C.
3. And if so, automatically absorbing.
4. And if the current object is A, traversing all the flowchart objects on the current interface, and if the currently traversed object is an arrow or a straight line and the direction is transverse, setting the object as D.
5. And the logic above judges whether A is on the left side, the right side, the middle and other adsorbable positions of D, and if so, the adsorption is carried out automatically.
6. And if the current object is A, traversing all the flow chart objects on the current interface, if the current traversed object is a broken line arrow or a broken line, setting the object as E, and judging whether the transverse line part of the E can be automatically adsorbed by the A.
7. And if the current object is B, traversing all the flow chart objects on the current interface, and if the current traversed object is a circular arc rectangle, a diamond, a sub-rectangle, a wavy rectangle, an ellipse or a parallelogram, setting the object as F.
8. And the logic is the same as the logic above, whether the left side and the right side of B are in the right side or the left side of F within a certain range is judged, and if so, the adsorption is automatically carried out.
9. And if the current object is B, traversing all the flow chart objects on the current interface, and if the current traversed object is an arrow or a straight line and the direction is vertical, setting the object as G.
10. And if so, automatically absorbing.
11. And if the current object is B, traversing all the flow chart objects on the current interface, if the current traversed object is a broken line arrow or a broken line, setting the object as H, and judging whether the vertical line part of the H can be automatically adsorbed by the B.
In the third case:
1. when the current moving object is a broken line arrow or a broken line, the direction of the current object needs to be judged first, and if the current moving object is from top to bottom and then to the right, the object is set as A; if the distance from the top to the bottom to the left is larger than the distance from the top to the bottom to the left, the object is set as B; if the direction is from bottom to top to right, the object is set as C; if from bottom to top to left, let this object be D.
2. And if the current object is A, traversing all the flow chart objects on the current interface, and if the current traversed object is a circular arc rectangle, a rhombus, a sub-rectangle, a wavy rectangle, an ellipse or a parallelogram, setting the object as E.
3. And the logic above, judging whether the top or the right of A is within a certain range of the bottom or the left of E, such as automatic adsorption.
4. If the current object is A, traversing all the flow chart objects on the current interface, if the current traversed object is an arrow or a straight line, firstly judging the direction of the object, and if the current traversed object is a vertical line, setting the object as F; if the line is a horizontal line, the object is G.
5. And judging whether the transverse part of the A can be automatically adsorbed with the F or not by the same logic as the above.
6. And the logic above judges whether the vertical part of A can be automatically adsorbed with G.
7. If the current object is A, all the flow chart objects on the current interface are traversed, if the current traversed object is a broken line arrow or a broken line, the direction of the object is firstly judged, and the adsorption rule is the same as the logic.
8. The object adsorption logic in other directions is similar and is not listed.
