The following will describe in detail.

The embodiment of the application provides a content display method which can be executed by a terminal.

Referring to fig. 2, fig. 2 is a flow chart of a content display method according to an embodiment of the present application. The content display method comprises the following steps:

in step 101, an input track and an input track point corresponding to the input track are acquired.

With the rapid development of electronic technology, intelligent interactive tablets have been widely used in the fields of teaching, conferences and the like, thereby greatly facilitating the work and study of people. In the actual use process of the intelligent interaction panel, the intelligent interaction panel displays display content, the display content is an image and can be a teaching content or a conference content, a user can generate an input track on the display content by sliding and touching a screen of the intelligent interaction panel so that a corresponding target content can be selected according to the input track, please refer to fig. 3 together, the user can input a touch down point through touching the screen by a finger, a corresponding selection line object can be created on the screen, the color is initialized to be red, the line width is 2f (pixels) and a dotted line effect, the display content is distinguished from a subsequent writing track, the spot of the touch down point is drawn, the first point is saved to the selection point queue sPoints, the sliding is performed, the touch down point spot is generated, the movement point is saved to the selection point queue sPoints, finally the finger is lifted to generate a touch up point, the start point is drawn, the start point is saved to the selection point sPoints, the corresponding input track is generated, the terminal can acquire the input track and the corresponding input track is the input track, and the input coordinate of the input point on the screen can be formed.

In step 102, a corresponding selection boundary region is determined from the input trajectory points.

In this embodiment of the present application, the display content may include a target content, where the target content is an object that needs to be taught or explained, and may be an object or a writing track, where the object is an object that needs to be taught or explained by a user alone, and may be an object such as an automobile, where the writing track is a segment of a handwriting track that needs to be taught or explained by a user alone, and the display content includes a plurality of target contents, and the input track is used to determine a selected target content, so that a selection boundary area selected by the track point needs to be determined according to an input track point, and the selection boundary area may surround the input track, that is, each input track point in the selection boundary area box, and in order to generate a more accurate selection boundary area, an area that surrounds the track point with an area as small as possible is used as the selection boundary area.

In some embodiments, the determining a corresponding selection boundary region from the input trajectory points includes:

(1) Acquiring track coordinate data of each track point to obtain a track coordinate data set;

(2) Generating a corresponding first minimum bounding rectangle according to the track coordinate data set, wherein the first minimum bounding rectangle surrounds each track point;

(3) The first minimum bounding rectangle is determined as the selected bounding region.

The track coordinate data of each track point may be obtained to obtain a track coordinate data set formed by a plurality of track point data, further, a first minimum bounding rectangle surrounding the track coordinate data set may be generated, and the first minimum bounding rectangle may be determined as a selected boundary area, for example, please refer to fig. 4 together, a first minimum bounding rectangle surrounding the track coordinate data set of the input track may be generated, where the first minimum bounding rectangle is the selected boundary area in the graph, and the selected boundary area may be obtained by calculation, for example, calculating the selected boundary area of the input track, defining sRectF for storing boundary values, and performing the boundary area of the mpa track after performing the sRectF.

In step 103, a target boundary region of the target content is determined.

In order to determine the target content selected by the input track, a target boundary area of each target content needs to be acquired, wherein the target boundary area can be the minimum circumscribed rectangle of the target content, i.e. the target boundary area surrounds the target content under the condition of the minimum area.

In some embodiments, the content display method further comprises: acquiring a writing boundary area corresponding to the writing track;

the determining a target boundary region of the target content includes: the written bounding region is determined as the target bounding region.

When the target content is a writing track, a corresponding second minimum bounding rectangle of the writing track may be obtained, that is, a writing boundary area, where the writing boundary area may enclose the writing track, and please continue to refer to fig. 4, a second minimum bounding rectangle enclosing the writing track may be generated, that is, the writing boundary area in the drawing.

In this way, the writing boundary region can be determined as the target boundary region.

In some embodiments, the content display method further comprises: acquiring an image boundary area covered by the image;

the determining a target boundary region of the target content includes: the image boundary region is determined as a target boundary region.

Wherein the determining the target boundary area of the target content includes: the written bounding region is determined as the target bounding region.

When the target content is an image, a corresponding third minimum circumscribed rectangle of the image can be obtained, namely an image boundary area, and the image boundary area can surround the image.

In this way, the image boundary region can be determined as the target boundary region.

In step 104, when the selection boundary region and the target boundary region overlap and the input trajectory overlaps with the target content, the target content is acquired.

In the related art, when a selection boundary region and a target boundary region overlap, a target content in the selection boundary region is regarded as a selected target content, so that a misconvergence easily occurs, for example, as shown in fig. 5, a writing track and an input track do not intersect even though the selection boundary region and the target boundary region overlap, but the related art may take the writing track as a target content, and accordingly, as shown in fig. 6, a misconvergence occurs in which an image and an input track do not intersect even though the selection boundary region and the image boundary region (i.e., the target boundary region) overlap.

In order to solve the above problem, the input track and the target content are overlapped when the selection boundary area and the target boundary area are overlapped, so that the target content can be judged to be the target content selected by the user, wrong selection is avoided, and the accuracy of selecting the target content is improved. In some embodiments, when the input track forms a closed shape and completely covers the target boundary region, the target content in the target boundary region may be directly determined as the target content that we need.

In some embodiments, when the target content is a written track, the obtaining the target content when the selection border region and the target border region overlap and the input track overlaps the target content comprises:

(1) Detecting whether the input track and the writing track are intersected when detecting that the selection boundary area and the target boundary area are overlapped;

(2) And when the input track is detected to be intersected with the writing track, acquiring the target content.

When the selection boundary area and the target boundary area are detected to be overlapped, it is indicated that the writing track in the target boundary area may be target content required by the user, and therefore, it is further required to detect whether the input track and the writing track intersect, and correspondingly, when the input track is detected to intersect with the writing track, it is indicated that the target content is target content required by the user. For example, as shown in fig. 7, when it is detected that the selection boundary region and the target boundary region (i.e., the writing boundary region) overlap, it is necessary to further detect whether the input track intersects the writing track.

In one embodiment, whether the input track intersects with the writing track or not may be determined by acquiring track points sPoints and writing track points mPoint of the input track, so as to acquire two points sPoints [ i ] and sPoints [ i+1] in the sPoints, and calculating whether any two adjacent points mPoint [ j ] and mPoint [ j+1] intersect with the writing track or not; referring to fig. 8, if the two end points C and D of the line segment CD are connected to one end point (a and B, only one of them) of the other line segment, the two end points cross the vector AB, if the result is different, the two end points C and D are respectively on two sides of the straight line AB, if the result is the same, the two end points CD are at one end of AB, and the two end points CD are certainly not intersected. Of course, it is not possible to prove that only C and D are at both ends of AB, but also prove that A and B are at both ends of CD by the same method, and both meet the requirement of proving line segment intersection at the same time, so that whether the input track and the writing track are intersected can be determined by a vector cross method.

With continued reference to fig. 7, it can be seen that the input track and the writing track intersect, so that the writing track can be obtained as target content, and accordingly, if the input track and the writing track do not intersect, it is indicated that the writing track is not the target content required by the user, and the writing track is directly discarded.

In some embodiments, when the target content is an image, the acquiring the target content when the selection border region and the target border region overlap and the input track overlaps the target content comprises:

(1.1) detecting whether the input trajectory intersects the image when it is detected that the selection boundary region and the target boundary region overlap;

(1.2) when it is detected that the input trajectory intersects the image, acquiring the target content.

When the selection boundary area and the target boundary area are detected to be overlapped, it is indicated that the image in the target boundary area may be the target content required by the user, so that it is further required to detect whether the input track and the image intersect, and correspondingly, when the input track is detected to intersect with the image, it is indicated that the target content is the target content required by the user, the image is acquired as the target content, and the situation of false selection is avoided.

In some embodiments, when the target boundary region formed by the image boundary region completely encloses the selected boundary region, the target content in the target boundary region may be directly determined as the target content that we need.

In step 105, a canvas area equal to the area of the selection border area is generated and the target content is displayed on the canvas area.

After determining the target content, the target content needs to be displayed by canvas to conduct teaching or conference discussion, with the development of the intelligent interaction panel, the screen resolution of the intelligent interaction panel is higher and higher, for example, the screen resolution of a 4k screen is higher and higher, in the related technology, a full-screen canvas is directly generated, the full-screen canvas occupies very high memory resources and can cause terminal clamping.

Further, a toolbar may be displayed on the canvas supporting editing functions.

As can be seen from the above, in the embodiment of the present application, the input track and the input track point corresponding to the input track are obtained; determining a corresponding selection boundary region according to the input track points; determining a target boundary area of target content; when the selection boundary area and the target boundary area overlap and the input track overlaps with the target content, acquiring the target content; a canvas area equal to the area of the selection border area is generated and the target content is displayed on the canvas area. Therefore, when the selection boundary region of the input track is detected to be overlapped with the target boundary region of the target content and the input track is also overlapped with the target content, the corresponding target content is acquired, the target content is displayed on the canvas region with the same area as the boundary region, the accuracy of selecting the target content is improved, and the memory consumption can be reduced.

In particular, in one particular embodiment, input unit 403 may include a touch-sensitive surface, as well as other input devices. The touch-sensitive surface, also referred to as a touch display screen or a touch pad, may collect touch operations thereon or thereabout by a user (e.g., operations thereon or thereabout by a user using any suitable object or accessory such as a finger, stylus, etc.), and actuate the corresponding connection means according to a predetermined program. Alternatively, the touch-sensitive surface may comprise two parts, a touch detection device and a touch controller. The touch detection device detects the touch azimuth of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch detection device and converts it into touch point coordinates, which are then sent to the processor 408, and can receive commands from the processor 408 and execute them.

Audio circuitry 406 may also include an ear bud jack to provide communication of the peripheral ear bud with the terminal.

The WiFi belongs to a short-distance wireless transmission technology, and the terminal can help the user to send and receive e-mail, browse web pages, access streaming media and the like through the WiFi module 407, so that wireless broadband internet access is provided for the user. Although fig. 11 shows a WiFi module 407, it is understood that it does not belong to the essential constitution of the terminal, and can be omitted entirely as required within the scope of not changing the essence of the invention.

The processor 408 is a control center of the terminal, and connects various parts of the entire handset using various interfaces and lines, and performs various functions of the terminal and processes data by running or executing software programs and/or modules stored in the memory 402, and invoking data stored in the memory 402, thereby performing overall monitoring of the handset.
