An embodiment of the present invention provides an operational method. The operation method can be applied to the electronic device 100 which is the same or similar to that in FIG. 1 , and in order to simplify the description, the following describes the operation method according to the first embodiment of the present invention, taking the electronic device 100 in FIG. 1 as an example. Not limited to this application.

In addition, it should be understood that the steps of the operation method mentioned in the embodiment may be adjusted according to actual needs, and may be performed simultaneously or partially simultaneously, unless the order is specifically described.

Reference is also made to Figs. 2, 3, 4A, and 4B. FIG. 2 is a schematic diagram of an operation method 200 according to the first embodiment of the present disclosure. The method of operation 200 can include the following steps.

In step S1, the detection module 120 can pass through the display module 110. Detecting the first input signal. In this embodiment, the first input signal is, for example, a control action performed by the user on the display module 110, such as single-point or multi-point touch (if the user touches the display module with one finger or two or more fingers) 110).

In step S2, the processing module 130 can determine whether the detected first input signal is a preset action for triggering the drawing assistance tool, and trigger the drawing assistance tool according to the first input signal. In the present embodiment, the drawing aid is, for example, the virtual ruler TOOL_1 in Fig. 3 or the virtual protractor TOOL_2 in Figs. 4A, 4B.

In step S3, the processing module 130 can control the display module 110 to display the drawing aid and the auxiliary line of the drawing aid (for example, the auxiliary line L1 of the virtual ruler TOOL_1 and the auxiliary line L2 of the virtual protractor TOOL_2). The auxiliary line is, for example, located at the edge of the drawing aid (for example, the auxiliary line L1 is located at the edge of the virtual ruler TOOL_1, and the auxiliary line L2 is located at the edge of the virtual protractor TOOL_2).

In step S4, the detection module 120 can detect the displacement of the first input signal through the display module 110, and the processing module 130 can control the display module 110 according to the displacement of the first input signal to adjust the drawing aid and The auxiliary line is displayed on a display module, a display size, and/or a display position.

In step S5, the processing module 130 can determine whether the first input signal continues by detecting the module 120, for example, determining whether the user continues to perform single or multiple touches on the display module 110. If yes, proceed to step S6; if no, proceed to step S7.

In step S6, in the state where the first input signal continues, the detection The measurement module 120 can detect the second input signal through the display module 110. In this embodiment, the second input signal is, for example, a control action performed by the user on the display module 110, such as a single touch, a single point slide, a multi-point touch, or a multi-point slide.

In step S7, in a state where the first input signal is stopped, the processing module 130 may turn off the drawing assistance tool (for example, turn off the virtual ruler TOOL_1 or the virtual protractor TOOL_2), and control the display module 110 to stop displaying the drawing aid and the drawing. Auxiliary line for auxiliary tools. In other words, the processing module 130 can operate to turn off the drawing aid according to whether the first input signal is stopped. In some embodiments, when the first input signal is stopped, the processing module 130 then closes the drawing aid without being limited to turning off the drawing aid in a particular step.

In step S8, after detecting the second input signal, the processing module 130 can determine whether the second input signal is located in the sensing area corresponding to the drawing aid (for example, the virtual ruler TOOL_1 corresponding to the sensing area SEN_1, the virtual protractor TOOL_2) Corresponding to the sensing area SEN_2). If yes, proceed to step S9, otherwise proceed to step S10. The sensing area of the drawing aid is, for example, located around the auxiliary line (for example, the sensing area SEN_1 of the virtual scale TOOL_1 is located around the auxiliary line L1, and the sensing area SEN_2 of the virtual protractor TOOL_2 is located around the auxiliary line L2).

In step S9, in a case where the second input signal is located in the sensing area of the drawing aid, the processing module 130 can control the display module 110 along the edge of the drawing aid according to the second input signal (or along the drawing aid). The tool's auxiliary line) shows the drawing trace (for example, along the edge of the virtual ruler TOOL_1) (Or along the auxiliary line L1) display the drawing trajectory TRACE_1 or display the drawing trajectory TRACE_2) along the edge green of the virtual protractor TOOL_2 (or along the auxiliary line L2).

In step S10, in a case where the second input signal is not located in the sensing area, the processing module 130 can control the display module 110 to display another drawing track independent of the edge of the drawing aid according to the second input signal (in other words, This other drawing trace is not displayed along the edge of the drawing aid).

By applying the embodiments described above, a virtualized drawing aid can be implemented. In addition, through the application of the drawing aid, the user's life experience of drawing with the physical tool can be closer to the user, so that the user can draw on the electronic device more smoothly.

In addition, according to an embodiment of the present disclosure, the processing module 130 may calculate auxiliary information of the drawing trajectory according to the drawing trajectory, such as the auxiliary information INFO_1 of the drawing trajectory TRACE_1 (for example, the length of the drawing trajectory TRACE_1) or the drawing trajectory. The auxiliary information INFO_2 of TRACE_2 (for example, the angle of the drawing track TRACE_2 with respect to the center O of the virtual protractor TOOL_2) controls the display module 110 to display the auxiliary information instantly or non-instantly.

In this way, when the user draws with the drawing aid, the user can quickly know the information of the drawing trajectory, and the convenience of drawing by the user using the drawing aid is significantly increased.

In the following paragraphs, more specific implementation details regarding the above-described operating method 200 will be provided, but the present invention is not limited thereto.

According to an embodiment of the present invention, in the above step S2, the processing module 130 can determine the number of sensing points of the detected first input signal (for example, the number of fingers touched by the user to the display module 110), and determine the mode of the triggered drawing aid according to the number of sensing points (eg, determine to trigger virtual Rule TOOL_1 or trigger virtual protractor TOOL_2).

According to an embodiment of the present invention, in the step S3, the processing module 130 determines the display of the drawing aid and the auxiliary line on the display module according to the sensing position of the sensing point on the display module 110 of the first input signal. The position, as well as the display angle or display size of the drawing aids and guides.

For example, with reference to FIG. 3 , in the case that the drawing aid is the virtual ruler TOOL_1 , the processing module 130 can perform all or part of the sensing points A, B, and C on the display module 110 according to the first input signal. The sensing position determines the display position of the virtual ruler TOOL_1 and the auxiliary line L1 displayed on the display module 110. In addition, the processing module 130 can determine the virtual ruler TOOL_1 and the auxiliary line L1 to be displayed on the display module according to the straight line D formed by the sensing positions of at least two points (for example, the sensing points A and B) of the sensing points A, B, and C. The display angle on 110. In an embodiment, the straight line D and the auxiliary line L1 have, for example, the same slope.

For example, referring to FIG. 4A , in the case that the drawing aid is the virtual protractor TOOL_2, the processing module 130 can sense all or part of the sensing points A and B according to the first input signal on the display module 110. The position determines the display position of the virtual protractor TOOL_2 and the auxiliary line L2 displayed on the display module 110. In addition, the processing module 130 can determine the virtual protractor TOOL_2 according to the distance between the sensing positions of the sensing points A and B. The display size displayed on the display module 110 and the auxiliary line L2 is displayed on the display module 110.

On the other hand, in the above step S4, in the case where the drawing aid is the virtual ruler TOOL_1 (refer to FIG. 3 in particular), the processing module 130 can shift all or part of the first input signal on the display module 110 according to the first input signal. The sensing positions of the subsequent sensing points A, B, and C determine the adjusted display position of the virtual ruler TOOL_1 and the auxiliary line L1 displayed on the display module 110. In addition, the processing module 130 can determine the virtual ruler TOOL_1 and the auxiliary line according to the straight line D formed by the sensing position of at least two of the displaced sensing points A, B, and C (for example, the sensing points A and B after the displacement). L1 is displayed on the adjusted display angle on the display module 110.

Similarly, in the case that the drawing aid is the virtual protractor TOOL_2 (refer to FIG. 4A, FIG. 4B in particular), the processing module 130 can sense the sensing points A and B after the displacement of the first input signal on the display module 110. The position is determined to determine the adjusted display position of the virtual protractor TOOL_2 and the auxiliary line L2 on the display module 110. In addition, the processing module 130 can determine the adjusted display size of the virtual protractor TOOL_2 displayed on the display module 110 and the auxiliary line L2 on the display module 110 according to the pitch I2 of the sensed points A and B after the displacement.

According to an embodiment of the present invention, in the above step S8, when the second input signal is a single touch, the processing module 130 can determine the sensing point of the contact (for example, the contact point of the finger contacting the display module 110). Whether the sensing position is in the sensing area. According to another embodiment of the present invention, in step S7, in a case where the second input signal is a single-point sliding, the processing module 130 can determine Whether the sensing position of the sliding starting sensing point (for example, the finger touches the contact starting point of the display module 110) is located in the sensing area.

For the sake of understanding, the following examples of the operation illustrate the case, but the case is not limited to this.

Referring to FIG. 3, in a first operational state, the user contacts the display module 110 with three fingers, for example. The processing module 130 determines the trigger virtual ruler TOOL_1 according to the number of sensing points (for example, 3). Next, the processing module 130 controls the display module 110 to display the virtual ruler TOOL_1 and the auxiliary line L1 of the virtual ruler TOOL_1 according to the sensing positions of the three fingers (ie, the sensing points A, B, C) of the touch display module 110. At this time, if the sensing positions of the sensing points A, B, and C are displaced, the processing module 130 detects the displacement through the detecting module 120 and the sensing positions of the sensing points A, B, and C after the displacement. Then, the processing module 130 controls the display module 110 according to the sensing position after the sensing points A, B, and C are displaced to adjust the display positions of the virtual ruler TOOL_1 and the auxiliary line L1. Then, if the user continues to touch the display module 110 with three fingers, the detection module 120 detects the second input signal through the display module 110; if the user stops contacting the display module 110 with three fingers, the processing module The group 130 closes the virtual ruler TOOL_1 and controls the display module 110 to stop displaying the virtual ruler TOOL_1 and the auxiliary line L1.

In the case where the user continues to touch the display module 110 with three fingers, the user can perform a single point sliding (or multi-point strike, single point) in the edge green (or the sensing area SEN_1) of the virtual ruler TOOL_1. Or more sliding). At this time, the processing module 130 determines that the single-point sliding is located in the sensing area SEN_1, so the processing module 130 controls the display module 110 to slide according to the single point. The edge of the virtual ruler TOOL_1 (or along the auxiliary line L1) displays the drawing track TRACE_1. In addition, the processing module 130 also calculates the auxiliary information (ie, length) INFO_1 of the drawing track TRACE_1, and controls the display module 110 to synchronously display the drawing track TRACE_1. With auxiliary information INFO_1. On the other hand, if the user does not perform single-point sliding (or multi-touch, single-point or multi-point sliding) on the edge of the virtual ruler TOOL_1 (or within the sensing area SEN_1), the processing module 130 controls the display mode. The group 110 displays another drawing track independent of the auxiliary line L1 according to this single point sliding (for example, the path through which the single point slides).

On the other hand, referring to Figures 4A and 4B, in a second operating state, the user contacts the display module 110 with two fingers, for example. The processing module 130 determines to trigger the virtual protractor TOOL_2 according to the number of sensing points (for example, 2). Next, the processing module 130 determines the virtual protractor TOOL_2 and the virtual protractor TOOL_2 according to the sensing position of the two fingers (ie, sensing points A, B) contacting the display module 110 and the sensing position between the sensing points A and B. The display position and display size of the auxiliary line L2, and control the display module 110 to display the virtual protractor TOOL_2 and the auxiliary line L2 of the virtual protractor TOOL_2. At this time, if the sensing position of the sensing points A and B of the user is displaced, the processing module 130 detects the displacement of the sensing position of the sensing points A and B through the detecting module 120, and the sensing point A after the displacement. The sensing position of B. Then, the processing module 130 controls the display module 110 to adjust the display positions of the virtual protractor TOOL_2 and the auxiliary line L2 according to the sensed positions of the displaced sensing points A and B and the sensing position spacing I2 of the sensing points A and B. Then, if the user continues to touch the display module 110 with two fingers, the detection module 120 detects the second input signal through the display module 110; if the user stops with two fingers When the display module 110 is touched, the processing module 130 closes the virtual protractor TOOL_2 and controls the display module 110 to stop displaying the virtual protractor TOOL_2 and the auxiliary line L2.

In the case where the user continues to touch the display module 110 with two fingers, the user can perform a single point sliding (or multi-point strike, single point) at the edge of the virtual protractor TOOL_2 (or within the sensing area SEN_2). Or more sliding). At this time, the processing module 130 determines that the single point sliding is located in the sensing area SEN_2, so the processing module 130 controls the display module 110 to slide along the edge of the virtual protractor TOOL_2 (or along the auxiliary line L2) according to the single point sliding. The drawing track TRACE_2 is displayed. In addition, the processing module 130 also calculates the auxiliary information (ie, angle) INFO_2 of the drawing track TRACE_2, and controls the display module 110 to synchronously display the drawing track TRACE_2 and the auxiliary information INFO_2. On the other hand, if the user does not perform single-point sliding (or multi-point strike, single-point or multi-point sliding) at the edge of the virtual protractor TOOL_2 (or within the sensing area SEN_2), the processing module 130 controls the display mode. The group 110 displays another drawing track independent of the auxiliary line L2 according to this single point sliding (for example, the path through which the single point sliding).

The following paragraphs will provide examples of other methods of operation of the present invention, but the present invention is not limited thereto.

Referring to FIG. 5, FIG. 6, and FIG. 7, FIG. 5 is a flowchart of an operation method 500 according to the second embodiment of the present disclosure. The method of operation 500 is substantially similar to the method of operation 200 described above, so that the repeated portions will be omitted.

In addition, the same as the operation method 200, the operation method 500 can be applied to the same or similar to the electronic device 100 in FIG. 1, and in order to simplify the description, In the following, according to an embodiment of the present invention, the operation method 500 is described by taking the electronic device 100 in FIG. 1 as an example, but the present application is not limited to this application.

Method of operation 500 can include the following steps T1-T8. The main difference between the operation method 500 and the foregoing operation method 200 is that the operation method 500 is not limited to the detection of the second input signal when the first input signal continues. The following will be described in detail through steps T1-T8.

Step T1 can refer to step S1 of the foregoing operation method 200, and therefore will not be described herein.

In step T2, the processing module 130 can determine whether the detected first input signal is a preset action for triggering the drawing assistance tool, and operatively trigger the drawing assistance tool according to the first input signal. Different from the step S2 of the operation method 200, in the embodiment, a plurality of trigger keys may be preset, for example, the trigger key ICON_1 (for example, to trigger the virtual ruler TOOL_1 in FIG. 3) and the trigger key ICON_2 (for example, The virtual protractor TOOL_2) in FIGS. 4A and 4B is triggered. When the processing module 130 determines that the detected first input signal (for example, a single touch) is located on the trigger button of the display module 110, the processing module 130 triggers the drawing assistance tool.

In addition, when it is noted that the preset action of triggering the drawing assistance tool may be a specific single point sliding (for example, an L-shaped sliding, a U-shaped sliding) or a multi-point sliding, and is not limited to the above-mentioned triggering key.

In step T3, the processing module 130 can control the display module 110 to display the drawing aid and the auxiliary line of the drawing aid.

For example, the adjusted user input can drag the drawing aid and the auxiliary line in a single point sliding manner to adjust the display position of the drawing aid and the auxiliary line, and adjust the drawing aid and the auxiliary line in a multi-point sliding manner. Display angle and display size.

In step T5, the detection module 120 can detect the second input signal through the display module 110. Different from step S5 of the operation method 200, in this embodiment, it is not necessary to first determine whether the first input signal continues to perform step T5. That is, even if the first input signal has been stopped, the processing module 130 does not close the drawing aid, and the display module 110 continues to display the auxiliary lines of the drawing aid and the drawing aid.

On the other hand, when it is noted that, in this embodiment, since the drawing aid is not determined by whether the first input signal continues to be determined, the display module 110 can display a close button of the drawing aid (as shown in FIG. 7). Close button CLOSE). The detection module 120 can detect the third user input through the display module 110. The processing module 130 can determine whether the third user input is located at the close button, and if the third user input is located at the close button, close the drawing aid, and control the display module 110 to stop displaying the drawing aid and the drawing aid. Auxiliary line.

Steps T6-T8 can refer to the steps of the foregoing operation method 200, respectively. S8-S10, so I won't go into details here.

For the sake of understanding, the following examples of the operation illustrate the case, but the case is not limited to this.

Referring to Figure 6, in a third operational state, the user, for example, makes a single touch on the trigger key ICON_2. The processing module 130 determines that the contact point of the user contacting the display module 110 is located at the trigger key ICON_2, so the processing module 130 triggers the virtual protractor TOOL_2. Next, referring to FIG. 7, the processing module 130 controls the display module 110 to display the virtual protractor TOOL_2 and the auxiliary line L2 of the virtual protractor TOOL_2 according to the preset display position and the preset display size. In addition, the display module 110 can display the virtual protractor TOOL_2 while displaying the virtual protractor TOOL_2, so that the user can close the virtual protractor TOOL_2 by contacting the close button CLOSE. On the other hand, after the virtual protractor TOOL_2 is displayed, the user can drag the virtual protractor TOOL_2 and the auxiliary line L2 by a single-point sliding method, or adjust the display size of the virtual protractor TOOL_2 and the auxiliary line L2 by a multi-point sliding manner.

Next, in a state where the virtual protractor TOOL_2 is turned on, the user can slide a single point on the auxiliary line L2, for example, to perform drawing. For the specific operation, refer to the operation example in the operation method 200, and details are not described herein.

Through the above settings, virtualized drawing aids can also be implemented. In addition, by applying the above-mentioned embodiments, the user can use the drawing aid tool to draw and simultaneously know the information of the drawing trajectory drawn by the user, and significantly increase the convenience of the user to draw with the drawing aid.
