detailed description

In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

Please refer to FIG. 1, which is a schematic diagram of an operating environment of a method for locally selecting a trajectory provided by the first embodiment. The electronic device 1 can be an electronic paper, an electronic book, a car display, a tablet computer, a smart phone, a smart watch, a smart bracelet, and the like. Exemplary embodiments of electronic devices include, but are not limited to, electronic devices equipped with other operating systems of iOS@Android@Windows Phone@者. Electronic devices usually support multiple applications, such as one or more of the following: drawing applications, rendering applications, word processing applications, web page creation applications, disk editing applications, spreadsheet applications, game applications , Phone applications, video conferencing applications, email applications, instant messaging applications, exercise support applications, photo management applications, digital camera applications, digital video camera applications, web browsing applications, digital music players Applications, and/or digital video player applications. The electronic device 1 includes a touch display assembly 10.

Please refer to FIG. 2, which is a schematic flowchart of a method for locally selecting a trajectory provided by the first embodiment. The method of locally selecting a trajectory is executed by an electronic device, and the method includes the following steps.

Step S201, displaying a track on the touch display component, the track including one or more sub-tracks. As shown in FIG. 3, the electronic device 1 displays a trajectory S, and the trajectory S includes S1 to S4. Wherein, the trajectory S may be a trajectory generated by the electronic device 1. The trajectory S may also be a trajectory formed after processing the received external trajectory. Among them, the external track can be a picture containing the track or a collection of track points. When the trajectory S is the trajectory generated by the electronic device 1, the trajectory S is a collection of continuous trajectory points. For example, when an external touch object (such as a stylus, a finger, etc.) slides in the touch display assembly 10, the electronic device 1 can follow The continuous track points generated by the sliding of the external object are detected and recorded and displayed to form a track S. When the external trajectory sent by the receiving external device is an image, the electronic device 1 may divide the trajectory in the image according to a preset rule and obtain corresponding trajectory points to form the trajectory S. The preset rule may be based on the trajectory in the image. The feature can be divided according to the location of the trajectory in the image; when the external trajectory sent by the receiving external device is a collection of data points, the trajectory S can be formed by analyzing the collection of trajectory points.

Step S203: Detect whether there is a touch operation on the touch display component displaying the track. Specifically, after displaying the trajectory, the electronic device 1 detects whether an external object operates the touch display component, so as to detect whether the user operates the trajectory. For example, the user can click or long-press the track to be selected.

Step S205, when there is a touch operation, obtain coordinate information corresponding to the touch operation. Specifically, when a touch operation is detected, the electronic device 1 obtains coordinate information of the touch operation, so as to further identify whether the touch operation is an operation of the user on the track.

Step S207: Select a sub-track corresponding to the coordinate information. Specifically, when the touch operation operates on the track, the coordinate information corresponds to the track point on the track, and the electronic device 1 can find the corresponding sub-track according to the coordinate information. Specifically, step S207 further includes: step S2070, acquiring the track point corresponding to the coordinate information; step S2072, determining the sub-track according to the acquired sub-track identifier of the track point.

In the foregoing embodiment, the foregoing method can select the corresponding sub-track according to the user's touch operation on the track, which is more flexible. In addition, the above method can not only select local trajectories, but also select external trajectories, which has better compatibility.

In some feasible embodiments, the sub-track includes a set of track points, and each track point includes a sub-track identifier for marking the sub-track to which it belongs. Referring to FIG. 4, step S2072 further includes the following steps.

Step S401: Find the track point closest to the touch point from all track points of the track according to the coordinate information of the touch point. Specifically, the electronic device 1 calculates the corresponding distance according to the coordinate information and the coordinates of each track point in the track S, and then obtains the track point corresponding to the minimum distance from the track S.

Step S403, detecting the number of track points found. Specifically, there may be two or more track points with the same distance as the touch point in the track S, and the distance between the track points is the smallest compared to other track points, and if these track points belong to different sub-tracks, they cannot Identify which sub-track is selected. Therefore, when the number of track points found is one, step S405 is executed, and when the number of track points found is greater than 1, step 409 is executed. Specifically, when the number of track points obtained is 1, it indicates that the touch operation is valid this time, and step S405 is executed. Otherwise, it means that this touch operation is invalid, and step S409 is executed.

Step S405: Obtain the sub-track identifier of the found track point. As shown in FIG. 5, the trajectory S includes SS ₁ to SS ₄ , and the trajectory identifiers of SS ₁ to SS ₄ are 0 to 3, respectively. Each sub-track of each sub-track is represented by a corresponding track identifier. Specifically, when the track point found is A, the identifier 0 of A is obtained.

Step S407: Select a corresponding sub-track according to the acquired sub-track identifier. Specifically, when the electronic device 1 obtains the trajectory 0, the sub-trajectory SS ₁ with the sub-trajectory identification 0 can be successfully selected. Preferably, the selected sub-track SS _1, SS ₁ sub tracks may be highlighted for other tips or tips.

Step S409, outputting a selection failure prompt to prompt the user to select again. Specifically, when the touch operation is an invalid operation, the electronic device 1 may vibrate or display corresponding information to prompt the user to inform the user that the operation is invalid, so as to perform the next operation.

In the foregoing embodiment, the foregoing method may select the corresponding sub-track by the track point closest to the touch point. In addition, each sub-track is set with a corresponding sub-track identification, which can quickly and completely select the required sub-track. In addition, the above method outputs corresponding prompt information when the touch operation is invalid or effective, making the human-computer interaction more friendly.

In some feasible embodiments, the track point of each sub-track includes a position identifier for indicating the track point in the sub-track. For example, the position identifier is used to identify the track point as a starting point, an intermediate point, or an end point. The sub-tracks can be sorted according to the position identification. After the corresponding track point is obtained, the sub-track to which it belongs can be selected according to the location identifier of the track point. For example, if the track point is an intermediate point, you can find the starting point and the ending point in the forward and backward directions to obtain the sub-track to which the track point belongs. In the same way, if the track point is the starting point, the end point is searched backward, and the sub-track to which the track point belongs can be found. If the track point is the end point, search forward to the starting point, you can find the sub-track to which the track point belongs.

In some feasible embodiments, after selecting the corresponding sub-track, corresponding operations can be performed on the sub-track. In this embodiment, the operation is the disassembling operation as an example. Among them, the disassembly and assembly operations include splitting and merging the tracks. Specifically, the method further includes: receiving and executing an instruction for instructing the trajectory to be split or combined for display according to the subject identifier. Wherein, the subject identifier is used to mark the subject generating the track point. Track points with the same stroke identifier all have the same subject identifier. In this embodiment, when a sub-track is selected, if a split or merge instruction is received, the selected sub-track can be split and displayed from the track, or the selected track can be merged and displayed again.

Specifically, please refer to Figures 6 and 7, which show schematic diagrams of the trajectory before and after the trajectory is split. In Fig. 6, the trajectory S includes sub-trajectories SS ₁ to SS ₄ . Wherein the sub-track SS subject identification of NS ₁ ~ SS ₄ are all 0, SS represents a sub-track ₁ ~ SS ₄ generated by the same body. The sub-track identifiers of trajectories SS ₁ to SS ₄ are respectively identified according to sequence numbers. As shown in Fig. 7, when the user selects the sub-trajectory SS ₁ and the trajectory SS ₂ and performs a split operation, the electronic device 1 can split the sub-trajectory SS ₁ and the sub-trajectory SS ₃ from the trajectory S, and separate SS ₁ The and SS ₃ touch display component 10 is displayed in the area A, the track SS ₂ and the track SS _{4 are} displayed in the area B, and then the sub-tracks SS ₁ to SS _{4 are} re-marked with new serial numbers. In this embodiment, the selected trajectory can be split and displayed, and the split sub-trajectory identification can also be updated, so that the split sub-trajectory is indistinguishable from the normally drawn sub-trajectory. Wherein, the split operation can be generated by selecting an icon in the touch display component 10, or it can be generated by directly operating in the touch display component according to a preset operation.

Understandably, if the subject identifiers NS of the sub-trajectories SS ₁ and SS _{2 are different} from the subject identifiers NS of the sub-trajectories SS ₃ and SS ₄ , and the subject identifiers NS of the sub-trajectories SS ₁ and SS ₂ are the same and the sub-trajectories SS ₃ and SS The subject identification NS of _{4 is} the same, which means that the subjects that generate the trajectories SS ₁ and SS _{2 are different} from the subjects that generate the trajectories SS ₃ and SS ₄ . After splitting, the trajectories SS ₁ and SS ₂ can be sent to a corresponding device (not shown) for display, and SS ₃ and SS ₄ can be sent to another corresponding device (not shown) for display.

Specifically, please refer to FIG. 8 and FIG. 9, which show schematic diagrams of the process of combined display of trajectories. In FIG. 8, the subject identification NS of the trajectory C is the same as the NS of the trajectory D, which means that the subject generating the trajectory C and the subject of the trajectory D are the same, such as the electronic device 1. After the user selects the track C and the track D and performs a corresponding merging operation, the electronic device 1 can merge the track C and the track D into one to form a track CD. Preferably, the merging of the trajectory C and the trajectory D can update the sub-trajectory identifiers in the trajectory C and the trajectory D, so that the merged sub-trajectory is indistinguishable from the normally drawn sub-track identifier. In some feasible embodiments, when the subject identifier NS of the track C is different from the subject identifier of the track D, when the track C and the track D are merged, the subject identifier NS in the merged track remains unchanged.

Please refer to FIG. 10 and FIG. 11 in combination. FIG. 10 is a method for disassembling and combining tracks according to the first embodiment of the present invention. In some feasible embodiments, the user can directly input split and merge instructions to split or merge the tracks without selecting sub-tracks. For example, when multiple users operate their own electronic devices separately, they need to be displayed and shared through a common screen. In addition, after editing the trajectory displayed on the shared screen, the edited trajectory can be returned to the electronic device of each user accordingly. Wherein, the trajectory includes the main body used to identify the generating trajectory point. The method for disassembling and combining tracks is applied to the electronic device 1', and specifically includes the following steps.

In step S1001, the track is displayed in the touch display component. As shown in Fig. 11, in this embodiment, the electronic device 1'displays a track on the touch display assembly 10'. Preferably, the electronic device 1'can communicate with multiple external electronic devices. In this embodiment, three electronic devices E, F, and D are taken as an example for description.

In step S1002, in the case of detecting an instruction for splitting or combining the display of the trajectory according to the subject identification, the trajectory is split or combined for display, and the subject identification is used to mark the subject generating the trajectory point.

Specifically, step S1002 includes steps S1002a and S1002b, wherein step S1002a is a split display step, and step S1002b is a combined display step.

Wherein, step S1002a specifically includes the following steps:

Step S10021: Split the trajectory into one or more trajectories according to the subject identification splitting, the track points of the same sub-track have the same subject identification, and the track points on different sub-tracks have different subject identifications. As shown in Fig. 12, the track R is displayed in the touch display assembly 10'. The trajectory R includes sub-trajectories R ₁ to R ₇ . Among them, the subject identifiers NS of the sub-trajectories R ₁ to R ₄ are the same, and they are all 0. The sub-trajectories R ₅ to R ₆ have the same subject identifier, and they are all 1. The subject identifier NS of the sub-trajectory R ₇ is 2, which means that the sub-trajectories R ₁ ˜R ₄ , R ₅ ˜R _{6, and} R ₇ are respectively generated by different devices. For example, the sub-trajectories R ₁ to R ₄ are generated by the E device, the sub-trajectories R ₅ to R ₆ are generated by the F device, and the sub-track R ₇ is generated by the G device. When the split instruction is received, the trajectory R can be divided into three trajectories r ₁ ～r ₃ according to the main body identification, r ₁ includes sub trajectories R ₁ ～R ₄ , r ₂ includes sub trajectories R ₅ ～R ₆ , and r ₃ includes Sub-trajectory R ₇ . In step S10023, the split trajectories are respectively sent to the corresponding subjects for display. Understandably, the three tracks r ₁ to r ₃ are displayed in the E, F, and G devices respectively. In some feasible embodiments, the split trajectories r ₁ ˜r ₃ can also be displayed in different areas of the touch display assembly 10 ′ at the same time.

Wherein, step S1002a specifically includes the following steps:

Step S10020: Obtain an external track sent by another electronic device. Specifically, when the user of another electronic device wants to share the content drawn by himself with everyone, he can send it to the electronic device 1'.

In step S10022, the external track and the track displayed by the electronic device are combined and displayed. When the electronic device 1'receives the external track, the external track and the track displayed in the electronic device 1'can be combined and displayed. Wherein, the subject identification of the external track is different from the subject identification of the display track in the touch display assembly. As shown in FIG. 13, when the electronic device 1'displays the trajectory r ₁ on the touch display assembly 10', and receives the trajectories r ₂ and r ₃ , the trajectories r ₁ to r _{3 are} combined, and the combined trajectory The sub-track identification of is updated, so that the merged sub-track is the same as the normally drawn sub-track identification.

In some feasible embodiments, before the trajectory is split and displayed or combined for display, the method for splitting and merging the trajectory further includes the steps of: selecting the sub-track to be split on the trajectory displayed in the touch component; The split display instructions.

In some feasible embodiments, after acquiring the external track sent by another electronic device, the method for detaching and disassembling the track further includes the step of detecting whether the external track has a subject identification; if the external track does not have a subject identification, add the external track The subject identification, which is different from the subject identification of the track displayed in the touch display assembly 10'.

In the above-mentioned embodiment, the above-mentioned method for detaching and combining trajectories can detach and combine trajectories according to the main body identification, and can realize merging and splitting of trajectories from different electronic devices for rapid splitting and merging.
