The processing module 130 can be used to receive the detection signal sent by the detection module 120, and to provide a control signal to the display module 110 to control the display screen of the display module 110; the processing module 130 can be, for example, a central processing unit, a microprocessor or other processing functions Appropriate component implementations.

An embodiment of the present invention provides an operation method, and the operation method can be applied to the same or similar electronic device 100 in FIG. The electronic device 100 is used as an example to describe the operation method, but the present invention is not limited to this application.

In addition, it should be understood that the steps of the operation method mentioned in this embodiment can be adjusted according to actual needs, and can even be executed simultaneously or partially simultaneously, unless the order is specifically stated.

Simultaneously refer to FIG. 2, FIG. 3, FIG. 4A, and FIG. 4B; FIG. 2 shows a schematic diagram of an operating method 200 according to the first embodiment of the present invention, and the operating method 200 may include the following steps:

In step S1, the detection module 120 can detect the first input signal through the display module 110; in this embodiment, the first input signal is, for example, a user's control action on the display module 110, such as single-point or multi-point touch (eg, the user touches the display module 110 with one finger or more than two fingers).

In step S2, the processing module 130 may determine whether the detected first input signal is a preset action for triggering the drawing aid, and trigger the drawing aid according to the first input signal; in this embodiment, the drawing aid For example, it is the virtual ruler TOOL_1 in FIG. 3 or the virtual protractor TOOL_2 in FIGS. 4A and 4B.

In step S3, the processing module 130 can control the display module 110 to display the drawing aids and the auxiliary lines of the drawing aids (such as the auxiliary line L1 of the virtual ruler TOOL_1, the auxiliary line L2 of the virtual protractor TOOL_2); The edge of the tool (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 aids and auxiliary lines displayed on the display module Display size, display angle or display position on the screen.

In step S5, the processing module 130 can judge whether the first input signal continues through the detection module 120, for example, judge whether the user continues to perform single-point or multi-point touch on the display module 110; if yes, proceed to step S6; if not , proceed to step S7.

In step S6, in the state where the first input signal continues, the detection module 120 can detect the second input signal through the display module 110; in this embodiment, the second input signal is, for example, the user's control on the display module 110 Actions such as single touch, single swipe, multi-touch or multi-swipe.

In step S7, in the state where the first input signal stops, the processing module 130 can close the drawing aid 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 tool and the drawing aid tool In other words, the processing module 130 can operate to close the drawing aid tool according to whether the first input signal stops; in one embodiment, when the first input signal stops, the processing module 130 immediately closes the drawing aid tool instead of Restricted to turning off drawing aids at specific steps.

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 tool (for example, the virtual ruler TOOL_1 corresponds to the sensing area SEN_1, and the virtual protractor TOOL_2 corresponds to the sensing area SEN_2 ); if yes, proceed to step S9, otherwise proceed to step S10; where the sensing area of the drawing aid tool is, for example, located around the auxiliary line (for example, the sensing area SEN_1 of the virtual ruler TOOL_1 is located around the auxiliary line L1, the induction of the virtual protractor TOOL_2 area SEN_2 is located around the auxiliary line L2).

In step S9, when the second input signal is located in the sensing area of the drawing aid, the processing module 130 can control the display module 110 to move along the edge of the drawing aid (or along the auxiliary edge of the drawing aid) according to the second input signal. line) to display the drawing trace (for example, display the drawing trace TRACE_1 along the edge of the virtual ruler TOOL_1 (or along the auxiliary line L1) or display the drawing trace TRACE_2 along the edge of the virtual protractor TOOL_2 (or along the auxiliary line L2).

In step S10, when 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 traces are not displayed along the edges of drawing aids).

By applying the above-mentioned embodiments, a virtual drawing aid tool can be realized; in addition, through the application of the drawing aid tool, it can be closer to the user’s life experience of drawing with a physical tool, so that the user can more smoothly use the electronic device to draw on.
