[0001] This application relates to the technical field of terminals, and particularly to a method for using a ruler and compass tool, an electronic device, and a storage medium. Background Art

[0002] With the development of electronic device technology, more and more applications are installed on electronic devices. Users can watch movies and TV shows, listen to music, navigate routes, or work through the applications installed on the electronic device.

[0003] For example, users can record text notes through the applications installed on the electronic device, and users can also conveniently draw graphics, angles, line segments, etc. through the ruler and compass tool provided by the applications installed on the electronic device. Currently, the functions of the ruler and compass tools provided by applications on electronic devices are relatively single and the operations are inconvenient. How to provide a method for using a ruler and compass tool with multiple functions and convenience remains to be further studied. Summary of the Invention

[0004] This application provides a method for using a ruler and compass tool, an electronic device, and a storage medium, providing a method for using a ruler and compass tool with multiple functions, improving the usage efficiency of the ruler and compass tool in the application, and improving the user experience.

[0005] In a first aspect, this application provides a method for using a ruler and compass tool. The method includes: the electronic device displays a first user interface of a first application, and a ruler icon is displayed on the first user interface; the electronic device receives a first operation of the user on the ruler icon, and a first ruler is displayed on the first user interface, and the first ruler includes a first cursor and a second cursor; the electronic device receives a second operation on the first ruler; in response to the second operation, the electronic device determines whether the second operation is a user operation acting between the first cursor and the second cursor; in the case where it is determined that the second operation is a user operation acting between the first cursor and the second cursor, the electronic device displays a first line segment on the first user interface, and the length of the first line segment is equal to the distance length between the first cursor and the second cursor.

[0006] Optionally, scales and scale values are displayed on the first ruler.

[0007] Optionally, between the first cursor and the second cursor may refer to the connecting line where the first cursor points to the second cursor.

[0008] Optionally, the second operation being a user operation acting between the first cursor and the second cursor may mean that the starting position of the second operation is on the connecting line between the first cursor and the second cursor, and the ending position of the second operation is also on the connecting line between the first cursor and the second cursor. Or, all or most of the trajectory of the second operation is located on the connecting line between the first cursor and the second cursor.

[0009] Through this method, the electronic device can use the first cursor and the second cursor on the first scale to automatically complete the line segment between the first cursor and the second cursor based on the user operation acting between the first cursor and the second cursor, achieving the quick drawing of a line segment with a specific length, which is equal to the distance between one cursor and the second cursor, saving the user's operation.

[0010] Combined with the first aspect, in a possible implementation, the second operation is a sliding operation along the first scale; the method further includes: when it is determined that the second operation is not a user operation acting between the first cursor and the second cursor, the electronic device displays a second line segment on the first user interface, and the length of the second line segment is equal to the length of the sliding trajectory of the second operation.

[0011] Optionally, the second operation not being a user operation acting between the first cursor and the second cursor may mean that the starting position of the second operation is not on the connection line between the first cursor and the second cursor, or the ending position of the second operation is not on the connection line between the first cursor and the second cursor, or all or most of the trajectory of the second operation is not on the connection line between the first cursor and the second cursor.

[0012] Combined with the first aspect, in a possible implementation, the second operation includes any one of the following: an operation of drawing a second line segment between the first cursor and the second cursor, where the length of the second line segment is less than the length of the first line segment, or a click operation between the first cursor and the second cursor.

[0013] In this way, the user can obtain the line segment between the first cursor and the second cursor without sliding along the first scale from the first cursor to the second cursor, saving the user's operation.

[0014] Combined with the first aspect, in a possible implementation, the first scale includes a first line and a second line, the first line is used to draw a straight line on the first user interface, and the second line is used to draw a curve on the first user interface.

[0015] In this way, the user can not only draw a straight line through the first scale but also draw a curve through the first scale.

[0016] Combined with the first aspect, in a possible implementation, the second operation is a sliding operation along the first line on the first scale.

[0017] Combined with the first aspect, in a possible implementation, a first number is displayed above the second cursor, and the first number is used to indicate the distance length between the first cursor and the second cursor. In this way, the user can view the distance length between the first cursor and the second cursor in real time.

[0018] In combination with the first aspect, in a possible implementation, the method further includes: the electronic device receives a third operation of the user on the second cursor; in response to the third operation, the electronic device overlays and displays the first cursor and the second cursor.

[0019] In this way, the user can overlay and display the first cursor and the second cursor, and the electronic device stops the function of automatically completing the line segment between the first cursor and the second cursor, enabling the user to draw a line segment of any length along the first scale.

[0020] In combination with the first aspect, in a possible implementation, after the electronic device overlays and displays the first cursor and the second cursor, the method further includes: the electronic device displays a first prompt message above the first cursor, and the first prompt message is used to indicate that the automatic completion of the line segment between the first cursor and the second cursor has stopped.

[0021] In combination with the first aspect, in a possible implementation, the first scale includes a first angle disc, and a second number is displayed on the first angle disc, and the second number is used to indicate the included angle between the first scale and the first reference line.

[0022] In this way, the user can view the included angle between the first scale and the first reference line through the second number to determine the orientation of the first scale.

[0023] In combination with the first aspect, in a possible implementation, the first reference line is parallel to the horizontal line. Optionally, not limited to the first reference line being parallel to the horizontal line, the first reference line can also be other reference lines, and the present application does not limit this.

[0024] In combination with the first aspect, in a possible implementation, the method further includes: the electronic device receives a fourth operation of the user on the first angle disc; in response to the fourth operation, the electronic device displays a second angle disc, and the second angle disc includes a plurality of angle values; the electronic device receives a fifth operation of the user on a first angle value among the plurality of angle values; in response to the fifth operation, the electronic device rotates the first scale along a first direction by the first angle value on the basis of the first reference line.

[0025] In this way, the user can rotate the first scale to change the orientation of the first scale.

[0026] In combination with the first aspect, in a possible implementation, after the electronic device rotates the first scale along the first direction by the first angle value on the basis of the first reference line, the method further includes: the electronic device receives a user operation to move the first scale to the starting point of a first line segment; the electronic device receives a user operation to draw along the first scale from the starting point of the first line segment and displays a third line segment on the first user interface, where the included angle between the third line segment and the first reference line is the first angle value.

[0027] In this way, the user can rotate the first scale to change the orientation of the first scale and draw a specific angle.

[0028] In combination with the first aspect, in a possible implementation, the method further includes: the electronic device receives a sixth operation of the user on the first angle disc; in response to the sixth operation, the electronic device displays a second angle disc, which includes a plurality of angle values and a first option; the electronic device receives a seventh operation of the user on the first option; in response to the seventh operation, the electronic device sets the first line segment as the second reference line; the electronic device receives an eighth operation of the user on a second angle value among the plurality of angle values; in response to the eighth operation, the electronic device rotates the first scale along a second direction by the second angle value on the basis of the second reference line.

[0029] In combination with the first aspect, in a possible implementation, after the electronic device rotates the first scale along the second direction by the second angle value on the basis of the second reference line, the method further includes: the electronic device receives a user operation to move the first scale to the starting point of the first line segment; the electronic device receives a user operation to draw along the first scale from the starting point of the first line segment and displays a fourth line segment on the first user interface, where the included angle between the fourth line segment and the second reference line is the second angle value.

[0030] The rotation of the first scale by the electronic device is obtained by rotating on the basis of a reference line. Generally, the reference line is fixed. For example, the default reference line can be parallel to the horizontal line. Through this method, the electronic device can use any line segment as the reference line based on the user operation, that is, change the reference line, and rotate a certain angle on the basis of the new reference line to achieve the convenient drawing of any angle by the electronic device.

[0031] In combination with the first aspect, in a possible implementation, when the second number is 0, the second reference line is the same as the first reference line; when the second number is not 0, the second reference line is different from the first reference line.

[0032] In combination with the first aspect, in a possible implementation, the method further includes: the electronic device receives a ninth operation of the user to reduce the first user interface by a first ratio; in response to the ninth operation, the electronic device also reduces the first scale by the first ratio; or, the electronic device receives a tenth operation of the user to enlarge the first user interface by a second ratio; in response to the tenth operation, the electronic device also enlarges the first scale by the second ratio.

[0033] In this way, the user can scale the first user interface, and the size of the corresponding first scale will also be scaled accordingly. Since the first scale displays scales, the scales displayed on the first scale will also be scaled correspondingly, ensuring that the length of the line segment displayed on the first user interface remains unchanged before and after scaling.

[0034] In a second aspect, the present application provides an electronic device, including one or more processors and one or more memories; wherein, the one or more memories are coupled to the one or more processors, and the one or more memories are configured to store computer program code, the computer program code includes computer instructions, and when the one or more processors execute the computer instructions, a method for using a ruler and compass tool in one of the possible implementation manners of any one of the above aspects is performed.

[0035] In a third aspect, an embodiment of the present application provides a computer storage medium, including computer instructions, and when the computer instructions run on an electronic device, a communication device is enabled to perform a method for using a ruler and compass tool in one of the possible implementation manners of any one of the above aspects.

[0036] In a fourth aspect, an embodiment of the present application provides a computer program product, and when the computer program product runs on a computer, the computer is enabled to perform a method for using a ruler and compass tool in one of the possible implementation manners of any one of the above aspects.

[0037] For the beneficial effects of the second aspect to the fourth aspect, reference may be made to the description of the beneficial effects in the first aspect, and the present application will not elaborate herein. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] Hereinafter, the technical solutions in the embodiments of the present application will be described clearly and in detail with reference to the accompanying drawings. Among them, in the description of the embodiments of the present application, unless otherwise specified, " / " means "or". For example, A / B may mean A or B; "and / or" in the text is only an association relationship describing associated objects, indicating that there can be three relationships. For example, A and / or B may mean: A exists alone, A and B exist simultaneously, and B exists alone. In addition, in the description of the embodiments of the present application, "a plurality" means two or more than two.

[0048] Hereinafter, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as implying or suggesting relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of the present application, unless otherwise specified, the meaning of "a plurality" is two or more.

[0049] The term "user interface (UI)" in the following embodiments of the present application is a media interface for interaction and information exchange between an application program or an operating system and a user, and it realizes the conversion between the internal form of information and the form acceptable to the user. The common manifestation form of the user interface is the graphical user interface (GUI), which refers to the user interface related to computer operations displayed in a graphical manner. It can be visual interface elements such as text, icons, buttons, menus, tabs, text boxes, dialog boxes, status bars, navigation bars, Widgets, etc. displayed on the display screen of the electronic device.

[0050] The present application provides a method for using a ruler and compass tool. The electronic device 100 can receive operations such as drawing a straight line, drawing a curve, drawing an angle, and drawing a graph by the user using the ruler function provided by the first application.

[0051] The electronic device 100 can receive and respond to the input operation of the user on the ruler icon in the first application, and display a first ruler on the first application interface of the first application. The first ruler includes a first line and a second line. Scale marks are displayed on the first line, and scale marks are also displayed on the second line. The first line is in a straight line shape, and the second line is in a curve shape. The user can draw a straight line of a preset length through the first line, and the user can also draw a curve of a preset length through the second line.

[0052] Optionally, a first cursor and a second cursor are displayed on the first line or the second line of the first scale. The first cursor and the second cursor can move along the scale marks on the first scale to change the distance between the first cursor and the second cursor. The first cursor and the second cursor are used to measure the distance between two points or draw a straight line or a curve of a preset length.

[0053] Optionally, a first disc is displayed on the first scale, and a first angle is displayed on the first disc. The first angle is used to indicate the included angle between the first scale and the horizontal straight line. The electronic device 100 can receive an operation by the user on the first disc, change the included angle between the first scale and the horizontal straight line, and the corresponding angle value displayed on the first disc will also change to prompt the current included angle between the first scale and the horizontal straight line.

[0054] It should be noted that the user input operation mentioned in this application can be an input operation by the user with a stylus, or an input operation by the user's finger, or other input methods, and this application does not limit this.

[0055] Next, the scale function provided by this application will be introduced in combination with different scenarios.

[0056] Display the first scale.

[0057] Figures 1A - 1D FIG. shows a schematic diagram of the electronic device 100 displaying the first scale in the first application.

[0058] Exemplarily, the first application can be a memo application.

[0059] Figure 1A FIG. shows the desktop of the electronic device 100. Application icons of multiple applications are displayed on the desktop of the electronic device 100. For example, a weather application icon, a stock application icon, a calculator application icon, a settings application icon, an email application icon, a music application icon, a video application icon, a browser application icon, a map application icon, a gallery application icon, a memo application icon, a voice assistant application icon, a beauty application icon, etc. A page indicator is also displayed below the multiple application icons to indicate the total number of pages on the desktop and the positional relationship between the currently displayed page and other pages. For example, the desktop can include three pages, and the white dot in the page indicator can indicate that the currently displayed page is the rightmost one of the three pages. Further optionally, there are multiple tray icons (such as a dial application icon, a message application icon, a contacts application icon, a camera application icon) below the page indicator, and the tray icons remain displayed during page switching. Optionally, a status bar is displayed in the upper part of the desktop. The status bar can include: one or more signal strength indicators of mobile communication signals (also known as cellular signals), a battery status indicator, a time indicator, etc.

[0060] Exemplarily, as Figure 1A shown, the electronic device 100 may receive an input operation (such as a click) from the user on the memo application icon on the desktop. In response to the user's input operation, the electronic device 100 may display Figure 1B the user interface 1100 shown. The user interface 1100 is the main interface of the memo application provided in the embodiments of the present application.

[0061] As Figure 1B shown, the user interface 1100 may include historical note information, and the current user has not created a note. The user interface 1100 also includes a to-do item option and a note addition option. Among them, the user can view one or more items that the user needs to process within a period of time through the to-do item option. The user can also create a new note through the note addition option.

[0062] Exemplarily, as Figure 1B shown, the electronic device 100 may receive an input operation (such as a click) from the user on the note addition option. In response to the user's input operation, the electronic device 100 may display Figure 1C the user interface 1200 shown.

[0063] As Figure 1C shown, the user can edit text in the user interface 1200. The user interface 1200 includes multiple editing options, such as a handwriting option, a ruler icon option 1201, a display style edit, an insert picture option, a recording option, and a setting option, etc. The user can use the ruler icon option 1201 to make the electronic device 100 display a first ruler on the user interface 1200, so that the user can use the first ruler to draw a graph on the user interface 1200.

[0064] Exemplarily, as Figure 1C shown, the electronic device 100 may receive an input operation (such as a click) from the user on the ruler icon option 1201 in the user interface 1200. In response to the user's input operation, the electronic device 100 may display Figure 1D the first ruler 1202 shown.

[0065] As Figure 1D shown, the first ruler 1202 includes a first line 1203 and a second line 1204. The first line 1203 is a straight line, and the second line 1204 is a curve. The user can draw a straight line through the first line 1203 of the first ruler 1202, and the user can also draw a curve through the second line 1204 of the first ruler 1202.

[0066] As Figure 1DAs shown, scale marks and scale values are displayed on the first line 1203. A user can draw a line segment of a preset length using the scale marks on the first line 1203.

[0067] It should be noted that Figure 1D The scale values shown are only for the purpose of explaining this application. The scale values displayed on the first line 1203 can also be in other styles, and this application does not limit this.

[0068] Optionally, the unit of the scale can be in millimeters, and the distance between every two scale marks can be 1 millimeter. The unit of the scale can also be other values, and this application does not limit this.

[0069] Optionally, scale marks and scale values can also be displayed on the second line 1204, and this application does not limit this.

[0070] As Figure 1D shown, the first line 1203 also includes a cursor 1205 and a cursor 1206, and the cursor 1205 and the cursor 1206 can be located at the position of the scale value "1". The initial distance between the cursor 1205 and the cursor 1206 is 20 millimeters.

[0071] As Figure 1D shown, the first scale 1202 also displays an angle disc 1207, and the number "0" is displayed on the angle disc 1207, thereby indicating that the angle between the first scale 1202 and the horizontal line is 0 degrees, that is, the first scale 1202 is parallel to the horizontal line.

[0072] Move the first scale or move the user interface.

[0073] Figures 2A - 2D Schematic diagram of the electronic device 100 receiving a user operation to move the first scale 1202 or move the user interface.

[0074] Exemplarily, as Figure 2A shown, the electronic device 100 displays a user interface 2100 and a first scale 1202. The user interface 2100 is similar to the user interface 1200, except that the user interface 2100 further includes an image 2101 drawn by the user, and the image 2101 can be composed of line segment AB, line segment BD, line segment AC, and line segment CD.

[0075] The electronic device 100 can receive a user operation on the first scale 1202 to change the display position of the first scale 1202.

[0076] Optionally, the user operation can be a long press and drag operation on the first scale 1202. The user operation can also be other operations, and this application does not limit this.

[0077] Exemplarily, asFigure 2A As shown, the user can long-press and drag the first scale 1202 so that the first scale 1202 moves towards the top of the electronic device 100. In response to the user operation, the first scale 1202 can be located at Figure 2B the position shown.

[0078] Not limited to dragging the first scale 1202 towards the top of the electronic device 100, the user can also drag the first scale 1202 towards the bottom of the electronic device 100, or the left side or the right side of the electronic device 100 to change the display position of the dragged first scale 1202. This application does not make any limitations in this regard.

[0079] From Figure 2A and Figure 2B it can be seen that when the user drags the first scale 1202, the position of the user interface 2100 does not change, Figure 2B the position of the image 2101 in Figure 2A is the same as the position of the image 2101 in the display screen.

[0080] Optionally, when the user drags the first scale 1202, the angle disc 1207 needs to be located within the display area of the display screen of the electronic device 100, and the edge of the angle disc 1207 cannot exceed the display area of the display screen of the electronic device 100. For example, the edge of the angle disc 1207 cannot be located outside the display area of the display screen of the electronic device 100, so that the user can view the angle between the first scale 1202 and the horizontal line in real time.

[0081] In some embodiments, the user can also drag the user interface 2100 to change the display position of the first scale 1202 in the user interface 2100.

[0082] The electronic device 100 can receive the user operation on the user interface 2100 to change the display position of the user interface 2100.

[0083] Optionally, the user operation can be an operation of long-pressing and dragging the user interface 2100. The user operation can also be other operations. This application does not make any limitations in this regard.

[0084] Exemplarily, as Figure 2C shown, the user can long-press and drag the user interface 2100 so that the user interface 2100 moves towards the top of the electronic device 100. In response to the user operation, the entire user interface 2100 is translated a certain distance towards the top of the electronic device 100, and the user interface 2100 can be located at Figure 2D the position shown. The position of the first scale 1202 remains unchanged, but the display position of the first scale 1202 in the user interface 2100 also changes accordingly.

[0085] Not limited to dragging the user interface 2100 to the top of the electronic device 100, the user can also drag the user interface 2100 to the bottom of the electronic device 100, or to the left or right of the electronic device 100 to change the display position of the first scale 1202 in the user interface 2100, and the present application does not make any limitations thereto.

[0086] By Figure 2C and Figure 2D It can be seen that when the user drags the user interface 2100, the position of the user interface 2100 changes. Figure 2D The position of the image 2101 in the display screen in Figure 2C is different from the position of the image 2101 in the display screen in

[0087] When the user interface is scaled, the first scale 1202 is also scaled proportionally.

[0088] Figures 3A - 3D Schematic diagram of the electronic device 100 receiving a user operation to scale the user interface.

[0089] In some embodiments, the electronic device 100 can receive a user operation to reduce the user interface 1200.

[0090] Exemplarily, as Figure 3A shown, the electronic device 100 can receive a user operation acting on the user interface 1200. In response to the user operation, the electronic device 100 can reduce the user interface 1200 and display Figure 3B the user interface 3100 shown.

[0091] Optionally, the user operation can be a user operation of pinching two fingers towards each other. The user operation can also be other operations, and the present application does not make any limitations thereto.

[0092] Exemplarily, the user interface 3100 can be reduced by a factor of 0.8 based on the user interface 1200. Correspondingly, the size of the image 2101 on the user interface 3100 / the size of the image 2101 on the user interface 1200 = 0.8.

[0093] Optionally, in response to the user operation of reducing the user interface 1200, the size of the first scale 1202 will also be correspondingly reduced, so that the scale shown on the first scale 1202 is also correspondingly reduced. The size of the first scale 1202 on the user interface 3100 / the size of the first scale 1202 on the user interface 1200 = 0.8.

[0094] In some embodiments, the electronic device 100 can receive a user operation to enlarge the user interface 1200.

[0095] Exemplarily, asFigure 3C As shown, the electronic device 100 can receive a user operation acting on the user interface 1200. In response to the user operation, the electronic device 100 can magnify the user interface 1200 and display Figure 3D the user interface 3200 shown.

[0096] Optionally, the user operation can be a user operation of two-finger reverse sliding. The user operation can also be other operations, which are not limited in this application.

[0097] Exemplarily, the user interface 3200 can be magnified 1.3 times based on the user interface 1200. Correspondingly, the size of the image 2101 on the user interface 3200 / the size of the image 2101 on the user interface 1200 = 1.3.

[0098] Optionally, in response to the user operation of magnifying the user interface 1200, the size of the first scale 1202 will also be magnified correspondingly, so that the scale shown on the first scale 1202 is also magnified correspondingly. The size of the first scale 1202 on the user interface 3200 / the size of the first scale 1202 on the user interface 1200 = 1.3.

[0099] Draw a straight line or a curve based on the first scale 1202.

[0100] Figures 4A - 4L Schematic diagram of the electronic device 100 receiving a user operation to draw a straight line or a curve.

[0101] The user can draw a straight line or a curve through the first scale 1202.

[0102] Exemplarily, as Figure 4A shown, the electronic device 100 can receive a sliding operation of the user along the second line 1204 on the first scale 1202, for example, moving from the position A ( Figure 4A the position where the single finger of the solid-line gesture in ) to the position B ( Figure 4A the position where the single finger of the dashed-line gesture in ) on the second line 1204, and then releasing the finger. The electronic device 100 can obtain Figure 4B the curve 4101 shown to implement drawing a curve through the first scale 1202.

[0103] Exemplarily, as Figure 4C shown, the electronic device 100 can receive a sliding operation of the user along the first line 1203 on the first scale 1202, for example, moving from the position C ( Figure 4C the position where the single finger of the solid-line gesture in ) to the position D ( Figure 4Cthe position where the single finger of the dotted-line gesture is located), and then release the finger, the electronic device 100 can obtain Figure 4D the line segment 4102 shown in the figure to draw a straight line through the first scale 1202.

[0104] Based on Figures 4A - 4D the description in the embodiment, when the user draws a straight line or a curve through the first scale 1202, for example, when drawing a straight line of the first length or a curve of the first length, the user needs to move the first length along the first line 1203 or the second line 1204 of the first scale 1202.

[0105] In some embodiments, the user can quickly draw a straight line or a curve through the cursor 1205 and the cursor 1206. For example, when the user needs to draw a line segment of the first length or a curve of the first length, the user can draw a line segment of the second length or a curve of the second length between the cursor 1205 and the cursor 1206, and the second length is less than the first length. The electronic device 100 can automatically complete the line segment with the length between the cursor 1205 and the cursor 1206, and the user does not need to move from the position where the cursor 1205 is located to the position where the cursor 1206 is located, saving the user's operation.

[0106] In some embodiments, the electronic device 100 can display the distance between the cursor 1205 and the cursor 1206 near (such as above) the cursor 1205 or the cursor 1206.

[0107] Exemplarily, as Figure 4E shown in the figure, a number 4103 is displayed above the cursor 1206, and the number 4103 includes the number "20mm", and the number 4103 is used to indicate the distance between the cursor 1205 and the cursor 1206.

[0108] In some embodiments, the electronic device 100 can also display the number 4103 above the cursor 1205, and this application does not make a limitation on this.

[0109] When the user changes the position of the cursor 1205 or the cursor 1206, the number displayed above the cursor 1206 will also change correspondingly.

[0110] Exemplarily, as Figure 4E shown in the figure, the user can move the cursor 1206 from the position E ( Figure 4E the position where the single finger of the solid-line gesture is located in the figure) along the first line 1203 to the position F on the first line 1203 ( Figure 4E the position where the single finger of the dotted-line gesture is located in the figure), and then release the finger, and the electronic device 100 can move the cursor 1206 to Figure 4F the position F shown in the figure.

[0111] In response to moving the cursor 1206 from position E to position F, the distance between the cursor 1205 and the cursor 1206 also changes. The electronic device 100 can display the number 4104 near (e.g., above) the cursor 1206. The number 4104 includes the number "30mm", and the number 4104 is used to indicate the distance between the cursor 1205 and the cursor 1206.

[0112] The user can also quickly draw a line segment between the cursor 1205 and the cursor 1206.

[0113] In a possible implementation, as Figure 4G shown, the electronic device 100 can receive an input operation by the user between the cursor 1205 and the cursor 1206, such as a click operation. In response to the user's input operation, the electronic device 100 can automatically draw a line segment between the cursor 1205 and the cursor 1206, obtaining Figure 4H the line segment 4105 shown. The length of the line segment 4105 is equal to the length between the cursor 1205 and the cursor 1206. In this way, without the user manually moving from the position where the cursor 1205 is located to the position where the cursor 1206 is located, the electronic device 100 can quickly draw the line segment 4105 between the cursor 1205 and the cursor 1206, saving the user's operation.

[0114] In other possible implementations, as Figure 4I shown, the electronic device 100 can receive a user operation by the user to draw a short line segment between the cursor 1205 and the cursor 1206, such as the user operation to draw the line segment 4106. The length of the line segment 4106 is less than the length between the cursor 1205 and the cursor 1206. In response to drawing the line segment 4106 between the cursor 1205 and the cursor 1206, the electronic device 100 can automatically draw a line segment between the cursor 1205 and the cursor 1206, obtaining Figure 4J the line segment 4105 shown. The length of the line segment 4105 is equal to the length between the cursor 1205 and the cursor 1206. In this way, without the user manually moving from the position where the cursor 1205 is located to the position where the cursor 1206 is located, the electronic device 100 can quickly draw the line segment 4105 between the cursor 1205 and the cursor 1206, saving the user's operation.

[0115] Not limited to the user operations of clicking and drawing short line segments, the electronic device 100 can also quickly draw a straight line between the cursor 1205 and the cursor 1206 based on other operations. This application does not make any limitations in this regard.

[0116] In some embodiments, the electronic device 100 can also receive a user operation to stop the function of automatically completing the line segment between the cursor 1205 and the cursor 1206, so that the user can draw a line segment of any length between the cursor 1205 and the cursor 1206.

[0117] Optionally, the electronic device 100 can receive a user operation to superimpose the cursor 1205 and the cursor 1206 and stop the function of automatically completing the line segment between the cursor 1205 and the cursor 1206.

[0118] Exemplarily, as Figure 4K shown, the electronic device 100 can receive an input operation for the cursor 1206, such as long-pressing the cursor 1206 and dragging the cursor 1206 to move towards the position where the cursor 1205 is located, so that the cursor 1206 and the cursor 1205 are superimposed and displayed.

[0119] Exemplarily, as Figure 4L shown, after the cursor 1206 and the cursor 1205 are superimposed and displayed, the electronic device 100 no longer displays the cursor 1206. The number "2" is displayed on the cursor 1205 to indicate that the cursor 1206 and the cursor 1205 are already superimposed and displayed.

[0120] Optionally, after the cursor 1206 and the cursor 1205 are superimposed and displayed, the electronic device 100 displays a prompt message 4107 near the cursor 1206. The prompt message 4107 includes the text "Disable positioning cursor", and the prompt message 4107 is used to prompt the user that the function of automatically completing the line segment between the cursor 1205 and the cursor 1206 has been stopped.

[0121] In some embodiments, the user can also drag the cursor 1206 again so that the cursor 1206 and the cursor 1205 are no longer superimposed and displayed. After the cursor 1206 and the cursor 1205 are no longer superimposed and displayed, the electronic device 100 can enable the function of automatically completing the line segment between the cursor 1205 and the cursor 1206 again. Specifically, reference can be made to Figures 4G - 4J the description in the embodiment, and details are not described herein again in this application.

[0122] Rotate the first scale 1202.

[0123] In some implementations, the electronic device 100 can receive a user operation to rotate the first scale 1202 to change the angle between the first scale 1202 and the horizontal line, so that the user can draw line segments, angles, and graphics of different angles through the first scale 1202.

[0124] Figures 5A - 5I Shows a schematic diagram of the electronic device 100 rotating the first scale 1202 based on a user operation.

[0125] Among them,Figures 5A - 5B FIG. Figures 5A - 5B shows a schematic diagram of an electronic device 100 rotating a first scale 1202 based on a user operation.

[0126] Exemplarily, as Figure 5A shown, the electronic device 100 may receive an operation of the user on the first scale 1202, such as an operation of long - pressing the first scale 1202 with two fingers and sliding the two fingers in the opposite direction. In response to the user operation, the electronic device 100 may rotate in the direction of the two - finger slide. Figure 5A In [the figure], the two fingers of the user rotate counter - clockwise, and the first scale 1202 also rotates counter - clockwise. As Figure 5B shown, the first scale 1202 may rotate to the Figure 5B angle shown. In response to the first scale 1202 rotating to the Figure 5B angle shown, the electronic device 100 may display the number "45" on the angle disc 1207, thereby prompting that the included angle between the first scale 1202 and the horizontal line is 45 degrees.

[0127] Figures 5C - 5F FIG. Figures 5C - 5F shows another schematic diagram of an electronic device 100 rotating a first scale 1202 based on a user operation.

[0128] Rotating the first scale 1202 by an angle A may be rotating the first scale 1202 by an angle A based on the 0 reference line. Optionally, the 0 reference line may be the horizontal line, and the 0 reference line may also be other reference lines, which are not limited in this application.

[0129] Exemplarily, as Figure 5C shown, the electronic device 100 may receive an input operation of the user on the angle disc 1207, such as a click. In response to the user input operation, the electronic device 100 may display the Figure 5D angle disc 5001 shown. Multiple angle values are displayed on the angle disc 5001, such as "0" - degree angle value, "45" - degree angle value, "90" - degree angle value, "135" - degree angle value, "180" - degree angle value, etc. An option 5109 is also displayed on the angle disc 5001. The user may long - press and drag the option 5109 to rotate the first scale 1202 to any angle.

[0130] Optionally, the included angle between the first scale 1202 and the horizontal line is 0 degrees, and the electronic device 100 may magnify and display the "0" - degree angle value to prompt that the current included angle between the first scale 1202 and the horizontal line is 0 degrees.

[0131] The user may choose to rotate the first scale 1202 to any angle.

[0132] Exemplarily, as Figure 5EAs shown, the electronic device 100 can long - press and drag the option 5109, so that the first scale 1202 can be rotated to any angle. When the electronic device 100 long - presses and drags the option 5109 counter - clockwise, the first scale 1202 can be rotated counter - clockwise. When the option 5109 is located at the scale line of the "45" - degree angle value, the electronic device 100 can thickly display the scale line of the "45" - degree angle value to prompt the current rotation angle of the first scale 1202.

[0133] Optionally, when the 0 reference line is horizontal, the electronic device 100 can rotate the first scale 1202 45 degrees counter - clockwise based on the horizontal line.

[0134] Optionally, Figure 5E In the first scale 1202 and the angle between the horizontal line is 45 degrees, the electronic device 100 can magnify the display of the "45" - degree angle value to prompt that the current angle between the first scale 1202 and the horizontal line is 45 degrees.

[0135] The user can confirm the rotation effect of the first scale 1202. When the user confirms that the first scale 1202 is rotated 45 degrees counter - clockwise, the user can release the finger, and the electronic device 100 can display Figure 5F the user interface shown.

[0136] In response to the first scale 1202 rotating to Figure 5F the angle shown, the electronic device 100 can display the number "45" on the angle disk 1207 to prompt that the angle between the first scale 1202 and the horizontal line is 45 degrees.

[0137] In some embodiments, when the user needs to continue rotating the first scale 1202, the electronic device 100 can receive the input operation of the user on the angle disk 1207, such as a click. In response to the user's input operation, the electronic device 100 can display Figure 5E the angle disk 5001 shown. Since the angle between the first scale 1202 and the horizontal line is 45 degrees, the option 5109 is still located at the scale line of the "45" - degree angle value.

[0138] Optionally, the angle between the first scale 1202 and the horizontal line is 45 degrees, and the electronic device 100 can magnify the display of the "45" - degree angle value to prompt that the current angle between the first scale 1202 and the horizontal line is 0 degrees.

[0139] The user can continue to drag option 5109 and rotate the first scale 1202 to other angles. For example, when the user drags option 5109 such that option 5109 is located at the scale line of the "90" - degree angle value, the electronic device 100 can rotate the first scale 1202 counter - clockwise by 90 degrees based on the 0 - degree reference line, that is, display the first scale 1202 perpendicular to the 0 - degree reference line (horizontal line).

[0140] Figures 5G - 5I Fig. shows another schematic diagram of the electronic device 100 rotating the first scale 1202 based on user operations.

[0141] Rotating the first scale 1202 by an angle A can be rotating the first scale 1202 by an angle A based on the 0 - reference line. Optionally, the 0 - reference line can be a horizontal line, and the 0 - reference line can also be other reference lines. This application does not limit this.

[0142] Reference Figure 5C According to the description in the embodiment, the electronic device 100 can receive a user's input operation on the angle disc 1207, such as a click. In response to the user's input operation, the electronic device 100 can display Figure 5G the shown angle disc 5002. Multiple angle values are displayed on the angle disc 5002, such as "0" - degree angle value, "45" - degree angle value, "90" - degree angle value, "135" - degree angle value, "180" - degree angle value, etc.

[0143] Optionally, the number "0" is displayed on the angle disc 5002 to indicate that the current included angle between the first scale 1202 and the horizontal line is 0 degrees.

[0144] The user can select any one of the multiple angle values, causing the first scale 1202 to rotate to the currently selected angle value by the user.

[0145] Exemplarily, as Figure 5G shown, the electronic device 100 can receive a user's input operation on the "45" - degree angle value among the multiple angle values, such as a click. In response to the user's input operation, the electronic device 100 can rotate the first scale 1202 counter - clockwise by 45 degrees and display Figure 5H the shown user interface.

[0146] Optionally, when the 0 - reference line is a horizontal line, the electronic device 100 can rotate the first scale 1202 counter - clockwise by 45 degrees based on the horizontal line.

[0147] In response to the first scale 1202 rotating to Figure 5HAt the shown angle, the electronic device 100 can display the number "45" on the angle disc 1207 to indicate that the included angle between the first scale 1202 and the horizontal line is 45 degrees.

[0148] In some embodiments, when the user needs to continue rotating the first scale 1202, as Figure 5H shown, the electronic device 100 can receive an input operation from the user on the angle disc 1207, such as a click. In response to the user's input operation, the electronic device 100 can display Figure 5I the shown angle disc 5002. The user can continue to rotate the first scale 1202 to other angles. For example, when the user clicks on the angle value of "90" degrees, the electronic device 100 can rotate the first scale 1202 counterclockwise by 90 degrees based on the 0-degree reference line, that is, display the first scale 1202 perpendicular to the 0-degree reference line (horizontal line). Again, for example, when the user clicks on the angle value of "45" degrees, the electronic device 100 can rotate the first scale 1202 counterclockwise by 45 degrees based on the 0-degree reference line. Since the included angle between the first scale 1202 and the 0-degree reference line is already 45 degrees, the position of the first scale 1202 remains unchanged and still shows Figure 5H the shown form.

[0149] Not limited to the above user operations for rotating the first scale 1202, the electronic device 100 can also rotate the first scale 1202 through other user operations, and this application does not limit this.

[0150] Quickly draw a specific angle based on the first scale 1202.

[0151] Figures 6A - 6I Shows a schematic diagram of the electronic device 100 quickly drawing a specific angle through the first scale 1202.

[0152] Exemplarily, as Figure 6A shown, the electronic device 100 can draw a line segment AB through the first scale 1202, and the line segment AB is parallel to the horizontal plane.

[0153] The user can rotate the first scale 1202. Exemplarily, as Figure 6A shown, the electronic device 100 can receive an input operation from the user on the angle disc 1207, such as a click. In response to the user's input operation, the electronic device 100 can display Figure 6B the shown angle disc 5002.

[0154] As Figure 6BAs shown, option 6001 is displayed below the angle disc 5002. Option 6001 includes the text "Set the current angle to 0 degrees", and option 6001 is used to prompt the user to set the 0-degree reference line. The electronic device 100 defaults the horizontal line as the 0-degree reference line, and the first scale 1202 rotates based on the 0-degree reference line. The user can set any line segment as the 0-degree reference line through option 6001.

[0155] When the user needs to rotate the first scale 1202 counterclockwise by 45 degrees, as Figure 6B shown, the electronic device 100 can receive the user's input operation for the "45" degree angle value among multiple angle values, such as a click. In response to the user's input operation, the electronic device 100 can rotate the first scale 1202 counterclockwise by 45 degrees and display Figure 6C the user interface shown. Figure 6C In [the figure] the included angle between the first scale 1202 and the 0-degree reference line is 45 degrees.

[0156] The user can move the first scale 1202 so that the first line 1203 of the first scale 1202 coincides with position A on the line segment AB. After that, the electronic device 100 can receive the user's drawing starting from position A along the first line 1203 to obtain Figure 6D the line segment AC shown. The included angle between the line segment AC and the line segment AB is 45 degrees.

[0157] Optionally, when the electronic device 100 monitors that the user drags the first scale 1202 towards position A on the line segment AB, the electronic device 100 can automatically adsorb the first scale 1202 so that the first line 1203 of the first scale 1202 coincides with position A on the line segment AB. Without the user manually making the first line 1203 of the first scale 1202 coincide with position A on the line segment AB, it can also improve the accuracy of the coincidence of the first line 1203 of the first scale 1202 with position A on the line segment AB.

[0158] In some embodiments, when the user needs to continue drawing other angle values based on the line segment AC, the electronic device 100 can set the line segment AC as the 0-degree reference line, so that the first scale 1202 can rotate other angle values based on the line segment AC. Without the user having to calculate how many angle values need to be rotated based on the horizontal line to obtain other angle values, it saves the user's calculation amount and enables more rapid drawing of any angle.

[0159] As Figure 6E shown, the electronic device 100 can receive the user's input operation for option 6001 (such as a click). In response to the user's input operation, the electronic device 100 can display Figure 6F the user interface shown.

[0160] As shown Figure 6F in Figure 6F , in response to a user's input operation on option 6001, the electronic device 100 may change the display form of option 6001. For example, the text "Reset to 0 degrees" is displayed on option 6001 to prompt the user that the current setting is that line segment AC is the 0-degree reference line.

[0161] Optionally, the user may also click on option 6001 again, causing the electronic device 100 to once again use the horizontal line as the 0-degree reference line.

[0162] After the electronic device 100 uses line segment AC as the 0-degree reference line, as Figure 6F shown in Figure 6F , the electronic device 100 may receive a user's input operation on the "45" degree angle value in the angle disc 5002, such as a click. In response to the user's input operation, the electronic device 100 may rotate the first scale 1202 counterclockwise by 45 degrees and display Figure 6G the user interface shown in Figure 6G .

[0163] As Figure 6G shown in Figure 6G , the first scale 1202 is rotated counterclockwise by 45 degrees based on line segment AC. In response to the 45-degree counterclockwise rotation based on line segment AC, the electronic device 100 may display the number "45" on the angle disc 1207, thereby prompting that the angle between the first scale 1202 and the 0-degree reference line (line segment AC) is 45 degrees.

[0164] As Figure 6G and Figure 6H shown in Figure 6G and Figure 6H , the user may move the first scale 1202 so that the first line 1203 of the first scale 1202 coincides with position A on line segment AB. After that, the electronic device 100 may receive a line segment AD drawn by the user starting from position A along the first line 1203, as Figure 6I shown in Figure 6I . The angle between line segment AD and line segment AC is 45 degrees.

[0165] Optionally, when the electronic device 100 detects that the user drags the first scale 1202 towards position A on line segment AB, the electronic device 100 may automatically snap the first scale 1202 so that the first line 1203 of the first scale 1202 coincides with position A on line segment AB. Without the user manually making the first line 1203 of the first scale 1202 coincide with position A on line segment AB, the accuracy of the coincidence of the first line 1203 of the first scale 1202 with position A on line segment AB can also be improved.

[0166] Figure 7 FIG. Figure 7 is a schematic flowchart of a method for using a ruler and compass tool provided by the present application.

[0167] S701. The electronic device displays a first user interface of a first application, and a scale icon is displayed on the first user interface.

[0168] Exemplarily, the first user interface can be Figure 1C the user interface 1200 shown, and the scale icon can be Figure 1C the scale icon option 1201 shown.

[0169] S702. The electronic device receives a first operation of the user on the scale icon, and displays a first scale on the first user interface. The first scale includes a first cursor and a second cursor.

[0170] Exemplarily, the first operation can be Figure 1C the input operation on the scale icon option 1201 in the user interface 1200 shown.

[0171] The first scale can be Figure 1D the first scale 1202 shown.

[0172] The first cursor can be Figure 1D the cursor 1205 shown, and the second cursor can be Figure 1D the cursor 1206 shown.

[0173] S703. The electronic device receives a second operation on the first scale.

[0174] In a possible implementation, the second operation includes any one of the following: an operation of drawing a second line segment between the first cursor and the second cursor, the length of the second line segment being less than the length of the first line segment, or a click operation between the first cursor and the second cursor.

[0175] In this way, the user can obtain the line segment between the first cursor and the second cursor without sliding along the first scale from the first cursor to the second cursor, saving the user's operation.

[0176] Exemplarily, the second operation can be Figure 4G the input operation acting between the cursor 1205 and the cursor 1206 shown, such as a click operation.

[0177] Exemplarily, the second operation can be Figure 4I the user operation of drawing a short straight line acting between the cursor 1205 and the cursor 1206 shown, such as the user operation of drawing the line segment 4106.

[0178] S704. In response to the second operation, the electronic device determines whether the second operation is a user operation acting between the first cursor and the second cursor.

[0179] S705. When it is determined that the second operation is a user operation acting between the first cursor and the second cursor, the electronic device displays a first line segment on the first user interface, and the length of the first line segment is equal to the distance length between the first cursor and the second cursor.

[0180] Exemplarily, the first line segment can be Figure 4H or Figure 4J the line segment 4105 shown.

[0181] Optionally, scales and scale values are displayed on the first scale.

[0182] Optionally, between the first cursor and the second cursor, it can refer to the connecting line where the first cursor points to the second cursor.

[0183] Optionally, the second operation is a user operation acting between the first cursor and the second cursor, which can mean that the starting position of the second operation is on the connecting line between the first cursor and the second cursor, and the ending position of the second operation is also on the connecting line between the first cursor and the second cursor. Or, all or most of the trajectory of the second operation is located on the connecting line between the first cursor and the second cursor.

[0184] Through this method, the electronic device can automatically complete the line segment between the first cursor and the second cursor based on the user operation acting between the first cursor and the second cursor through the first scale on the first scale, achieving the quick drawing of a line segment with a specific length, and the specific length is equal to the distance length between the first cursor and the second cursor, saving the user operation.

[0185] In a possible implementation, the second operation is a sliding operation along the first scale; the method further includes: when it is determined that the second operation is not a user operation acting between the first cursor and the second cursor, the electronic device displays a second line segment on the first user interface, and the length of the second line segment is equal to the length of the sliding trajectory of the second operation.

[0186] Optionally, the second operation is not a user operation acting between the first cursor and the second cursor, which can mean that the starting position of the second operation is not on the connecting line between the first cursor and the second cursor, or the ending position of the second operation is not on the connecting line between the first cursor and the second cursor, or all or most of the trajectory of the second operation is not on the connecting line between the first cursor and the second cursor.

[0187] In a possible implementation, the first scale includes a first line and a second line, the first line is used to draw a straight line on the first user interface, and the second line is used to draw a curve on the first user interface.

[0188] In this way, the user can not only draw a straight line through the first scale, but also draw a curve through the first scale.

[0189] Exemplarily, the first line may be Figure 1D the first line 1203 shown, and the second line may be Figure 1D the second line 1204 shown.

[0190] In a possible implementation, the second operation is a sliding operation along the first line on the first scale.

[0191] In a possible implementation, a first number is displayed above the second cursor, and the first number is used to indicate the distance length between the first cursor and the second cursor. In this way, the user can view the distance length between the first cursor and the second cursor in real time.

[0192] Exemplarily, the first number may be Figure 4E the number 4103 shown, or Figure 4F the number 4104 shown.

[0193] In a possible implementation, the method further includes: the electronic device receives a third operation of the user on the second cursor; in response to the third operation, the electronic device overlaps and displays the first cursor and the second cursor.

[0194] In this way, the user can overlap and display the first cursor and the second cursor, and the electronic device stops the function of automatically completing the line segment between the first cursor and the second cursor, so that the user can draw a line segment of any length along the first scale.

[0195] Exemplarily, the third operation may be Figure 4K a user operation of long-pressing the cursor 1206 and dragging the cursor 1206 to move along the first scale towards the position where the cursor 1205 is located as shown.

[0215] In a possible implementation, when the second number is 0, the second reference line is the same as the first reference line; when the second number is not 0, the second reference line is different from the first reference line.

For example: when a touch operation with a touch operation intensity less than the first pressure threshold acts on the short message application icon, the instruction to view the short message is executed. When a touch operation with a touch operation intensity greater than or equal to the first pressure threshold acts on the short message application icon, the instruction to create a new short message is executed.

[0281] The software system of the electronic device 100 can adopt a layered architecture, event-driven architecture, microkernel architecture, microservices architecture, or cloud architecture. In the embodiments of the present invention, the Android system with a layered architecture is taken as an example to exemplarily illustrate the software structure of the electronic device 100.

[0282] Figure 9 It is a software structure block diagram of the electronic device 100 in the embodiments of the present invention.

[0283] The layered architecture divides software into several layers, and each layer has clear roles and divisions of labor. The layers communicate with each other through software interfaces. In some embodiments, the Android system is divided into four layers, from top to bottom: the application layer, the application framework layer, the Android runtime and system libraries, and the kernel layer.

[0284] The application layer may include a series of application packages.

[0285] As Figure 9 shown, the application packages may include applications such as camera, gallery, calendar, call, map, navigation, WLAN, Bluetooth, music, video, short message, etc.

[0286] The application framework layer provides application programming interfaces (APIs) and programming frameworks for the applications in the application layer. The application framework layer includes some predefined functions.

[0287] As Figure 9 shown, the application framework layer may include a window manager, a content provider, a view system, a telephone manager, a resource manager, a notification manager, etc.

[0288] The window manager is used to manage window programs. The window manager can obtain the display screen size, determine whether there is a status bar, lock the screen, capture the screen, etc.

[0289] The content provider is used to store and obtain data, and make this data accessible to applications. The data may include videos, images, audio, dialed and answered calls, browsing history and bookmarks, phone books, etc.

[0290] The view system includes visible controls, such as controls for displaying text, controls for displaying pictures, etc. The view system can be used to build applications. The display interface can be composed of one or more views. For example, a display interface including a short message notification icon may include a view for displaying text and a view for displaying pictures.

[0291] The telephone manager is used to provide the communication function of the electronic device 100. For example, the management of call status (including connection, disconnection, etc.).

[0292] The resource manager provides various resources for applications, such as localized strings, icons, pictures, layout files, video files, and so on.

[0293] The notification manager enables an application to display notification information in the status bar. It can be used to convey messages of the notification type, and can automatically disappear after a short stay without user interaction. For example, the notification manager is used to inform that a download is completed, a message reminder, etc. The notification manager can also be a notification that appears in the system top status bar in the form of a chart or a scrolling text, such as a notification of a background-running application, or a notification that appears on the screen in the form of a dialogue window. For example, it prompts text information in the status bar, emits a prompt tone, the electronic device vibrates, the indicator light flashes, etc.

[0294] Android Runtime includes the core libraries and the virtual machine. Android runtime is responsible for the scheduling and management of the Android system.

[0295] The core libraries contain two parts: one part is the functional functions that the Java language needs to call, and the other part is the core libraries of Android.

[0296] The application layer and the application framework layer run in the virtual machine. The virtual machine executes the Java files of the application layer and the application framework layer as binary files. The virtual machine is used to perform functions such as the management of the object life cycle, stack management, thread management, security and exception management, and garbage collection.

[0297] The system libraries can include multiple functional modules. For example: surface manager, Media Libraries, 3D graphics processing library (such as: OpenGL ES), 2D graphics engine (such as: SGL), etc.

[0298] The surface manager is used to manage the display subsystem and provides the fusion of 2D and 3D layers for multiple applications.

[0299] The media libraries support the playback and recording of a variety of common audio and video formats, as well as static image files, etc. The media libraries can support a variety of audio and video coding formats, such as: MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc.

[0300] The 3D graphics processing library is used to implement 3D graphics drawing, image rendering, synthesis, and layer processing, etc.

[0301] The 2D graphics engine is the drawing engine for 2D drawing.

[0302] The kernel layer is the layer between the hardware and the software. The kernel layer contains at least a display driver, a camera driver, an audio driver, and a sensor driver.

[0303] Next, in combination with the capture and photographing scenario, the working processes of the software and hardware of the electronic device 100 are exemplarily described.

[0304] When the touch sensor 180K receives a touch operation, a corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes the touch operation into a raw input event (including information such as touch coordinates and the timestamp of the touch operation). The raw input event is stored in the kernel layer. The application framework layer obtains the raw input event from the kernel layer and identifies the control corresponding to the input event. Taking the touch operation as a touch click operation and the control corresponding to the click operation being the control of the camera application icon as an example, the camera application calls the interface of the application framework layer to start the camera application, and then starts the camera driver by calling the kernel layer, and captures a static image or video through the camera 193.

The computer can be a general-purpose computer, a special-purpose computer, a computer network, or other programmable devices. The computer instructions can be stored in a computer-readable storage medium or transmitted from one computer-readable storage medium to another. For example, the computer instructions can be transmitted from a website, computer, server, or data center to another website, computer, server, or data center by wire (such as coaxial cable, optical fiber, digital subscriber line) or wirelessly (such as infrared, wireless, microwave, etc.). The computer-readable storage medium can be any available medium that the computer can access or a data storage device such as a server or data center that includes one or more integrated available media. The available medium can be a magnetic medium (for example, a floppy disk, a hard disk, a magnetic tape), an optical medium (for example, a DVD), or a semiconductor medium (for example, a solid-state disk (SSD)), etc.
