[0002] At present, wearable devices such as smart watches are intelligent, lightweight and beautiful, and more and more people are willing to use wearable devices to exchange information. Due to the small screen of wearable devices, it is not convenient to perform screen touch operations on wearable devices (such as the dial of smart watches). Therefore, some wearable devices have added joystick functions. Taking smart watches as an example, the crown of the smart watch is used as a joystick. By shaking the crown in different directions, various interface selection functions of the smart watch can be controlled, which greatly optimizes the user experience and improves the operability of the smart watch.

[0003] Limited by the size of wearable devices, in order to integrate the joystick function into the wearable device, the joystick needs to be miniaturized. However, the related art generally requires the establishment of a special direction detection mechanism to detect the operating direction of the joystick, and the direction detection mechanism of the joystick needs to occupy a large space, resulting in a relatively complex structure of the joystick, which is difficult to meet the problem of miniaturization requirements of the joystick. For example, the related art generally uses resistors, infrared sensors or electromagnetic induction devices to detect the operating direction of the joystick, and these devices need to occupy a large space, which is difficult to meet the miniaturization requirements of the joystick.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0014] Currently, due to the size of smart watches, in order to integrate the joystick function into the crown of smart watches, the joystick needs to be miniaturized. However, existing joysticks generally require a special direction detection mechanism to detect the operating direction of the joystick. The direction detection mechanism of the joystick needs to occupy a large space, resulting in a complex structure of the joystick, which is difficult to meet the problem of miniaturization requirements. For example, in the related art, resistors, infrared sensors or electromagnetic induction devices are generally used to detect the operating direction of the joystick. These devices need to occupy a large space and are difficult to meet the miniaturization requirements of the joystick.

[0015] Based on this, in order to simplify the structure of the joystick, an embodiment of the present application provides a wearable device, in which the joystick is connected to the power ground, and a capacitor plate is set in the operable direction of the joystick. The joystick and the capacitor plate can constitute a capacitor, and the capacitor plate can be regarded as the positive plate of the capacitor, and the joystick can be regarded as the negative plate of the capacitor. Furthermore, when the user operates the joystick to move toward the capacitor plate, the capacitance of the capacitor changes, which is specifically manifested as a change in the magnitude of the current flowing through the capacitor plate. Then, the actual operating direction of the joystick can be detected by the change in the current of the capacitor plate. In this way, when a capacitive sensor is used to detect the actual operating direction of the joystick, the capacitive sensor includes a capacitor plate and a joystick. Since the joystick itself can be used as a part of the capacitive sensor after being grounded, and the capacitor plate of the other part of the capacitive sensor occupies a small space, the structure is relatively simple, and the demand for miniaturization of the joystick can be met.

[0016] The following is combined with Figure 1-Figure 10 The wearable device and control method provided by the embodiments of the present application are described in detail.

[0017] like Figure 1 As shown, the embodiment of the present application provides a wearable device 100, which may include: a capacitor plate 111 and a rocker 112, the capacitor plate 111 and the rocker 112 form a capacitive sensor 110, the rocker 112 is grounded, and the capacitor plate 111 is arranged in an operable direction of the rocker 112; The capacitive sensor 110 is used to detect the actual operation direction of the joystick 112 from the operable directions.

[0018] In the embodiment of the present application, the capacitor plate 111 can be energized, the joystick 112 is connected to the power ground, the capacitor plate 111 and the joystick 112 do not contact each other, a capacitor plate 111 and the joystick 112 can constitute a capacitor, the capacitive sensor 110 may include at least one capacitor, the capacitor plate 111 can be regarded as the positive plate of the capacitor, the joystick can be regarded as the negative plate of the capacitor, the distance between the capacitor plate 111 and the joystick 112 can be understood as the distance between the positive plate and the negative plate of the capacitor, and the distance between the positive plate and the negative plate of the capacitor determines the capacitance of the capacitor.

[0019] In the embodiment of the present application, the distance between the capacitor plate 111 and the joystick 112 can change as the user operates the joystick 112 to shake. For example, in a scenario where the user operates the joystick to shake toward the capacitor plate, the distance between the capacitor plate 111 and the joystick 112 changes, causing the capacitance of the capacitor to change, which is specifically manifested as a change in the magnitude of the current flowing through the capacitor plate 111. Then, the actual operation direction of the joystick can be detected by the change in the current of the capacitor plate, and better human-computer interaction can be achieved by using this function.

[0020] For example, the capacitor plate 111 and the rocker 112 may form a capacitor, and the capacitance C of the capacitor is given by: .

[0021] in, is the dielectric constant of vacuum, is the dielectric constant of the medium between the capacitor plate 111 and the rocker 112, is the mutual covering area between the capacitor plate 111 and the rocker 112, is the distance between the capacitor plate 111 and the rocker 112 .

[0022] In the wearable device of the embodiment of the present application, the capacitor plate 111 and the joystick 112 , , is a fixed value. When the joystick is shaken up, down, left, or right, the distance between the capacitor plate 111 and the joystick 112 will change. , thereby changing the capacitance of the capacitor. Further, when it is detected that the capacitance change reaches a certain threshold, it can be determined that the joystick moves to a specific position in a specific operable direction, thereby executing a specific function.

[0023] And because , is the charge of the capacitor, U is the voltage value on the surface of the capacitor. In the actual circuit, the embodiment of the present application can control the voltage on the surface of the capacitor to remain unchanged (that is, the working voltage of the capacitor plate 111 is a fixed value), and the capacitance change is determined by the charge change. Decide.

[0024] The formula for the charge change is: .

[0025] in, The time before the user operates the joystick 112 to move. The time after the user operates the joystick 112 to move, The current flowing through the capacitor plate 111.

[0026] Furthermore, in the wearable device, the voltage of the capacitor plate 111 is set to be constant, and the distance between the capacitor plate 111 and the joystick 112 can be determined by detecting the magnitude of the current flowing through the capacitor plate 111. Among them, the distance between the capacitor plate 111 and the rocker 112 is When the capacitance C of the capacitor increases, the charge of the capacitor As a result, the current flowing through the capacitor plate 111 The distance between the capacitor plate 111 and the rocker 112 When the capacitance C of the capacitor decreases, the charge of the capacitor As a result, the current flowing through the capacitor plate 111 It can be seen that when the user operates the joystick 112 to shake, when the distance between the capacitor plate 111 and the joystick 112 changes, the change in the distance between the capacitor plate 111 and the joystick 112 is inversely proportional to the change in the current flowing through the capacitor plate 111.

[0027] Furthermore, the actual operation direction of the joystick can be detected by the change in the current of the capacitor plate 111, and better human-computer interaction can be achieved by using this function. For example, when it is detected that the current of the capacitor plate 111 becomes larger, it can be determined that the distance d between the joystick 112 and the capacitor plate 111 becomes smaller, indicating that the joystick moves toward the direction close to the capacitor plate 111; for another example, when it is detected that the current of the capacitor plate 111 becomes smaller, it can be determined that the distance d between the joystick 112 and the capacitor plate 111 becomes larger, indicating that the joystick moves away from the capacitor plate 111.

[0028] In practical applications, the capacitor plate 111 can be a capacitor film, that is, a thin film capacitor sheet. The capacitor plate 111 takes up less space, which is conducive to the miniaturization of the joystick in the wearable device. In practical applications, the embodiment of the present application does not specifically limit the area size and shape of the capacitor plate 111. The embodiment of the present application can be set according to actual needs.

[0029] In practical applications, a part of the rocker 112 or the rocker 112 may have conductive properties, and the rocker 112 is connected to the power ground, so that the rocker 112 can be regarded as the negative plate of the capacitor. For example, the rocker 112 can be made of metal. In practical applications, the embodiment of the present application does not specifically limit the size and shape of the rocker 112. The embodiment of the present application can be set according to actual needs.

[0030] It should be pointed out that in the related art, it is necessary to set up special devices for detecting the operation direction of the joystick in the wearable device (such as resistors, infrared sensors or electromagnetic induction devices). These detection devices need to occupy a large space and it is difficult to meet the miniaturization requirements of the joystick.

[0031] In the scenario where the embodiment of the present application uses the capacitive sensor 110 to detect the actual operating direction of the joystick 112, the capacitive sensor 110 includes a capacitive plate 111 and a joystick 112. Since the joystick 112 itself can serve as a part of the capacitive sensor 110 after being grounded, and the capacitive plate 111 of the other part of the capacitive sensor 110 occupies a small space, the structure of the capacitive sensor 110 is relatively simple, which can meet the demand for miniaturization of the joystick in the wearable device 100.

[0032] According to the wearable device provided in the embodiment of the present application, the wearable device includes a capacitor plate and a rocker, the capacitor plate 111 and the rocker 112 form a capacitive sensor 110, the rocker is grounded, and the capacitor plate is arranged in the operable direction of the rocker; wherein the capacitive sensor is used to detect the actual operation direction of the rocker from the operable direction. In this way, in the case of detecting the actual operation direction of the rocker, the capacitor plate and the rocker form a capacitive sensor, and the actual operation direction of the rocker is detected by the capacitive sensor. Since the rocker itself can be used as a part of the capacitive sensor after being grounded, and the capacitor plate of the other part of the capacitive sensor occupies a small space, the structure of the capacitive sensor is relatively simple, which can meet the demand for miniaturization of the rocker in the wearable device.

[0033] In practical applications, in order to meet the personalized needs of the human-computer interaction function of the wearable device, the wearable device 110 may have one or more operating functions, and this application does not impose any specific restrictions.

[0034] Among them, the number of joysticks 112 in the wearable device 110 can be one or more, and this application does not make any specific restrictions.

[0035] Among them, for one joystick 112, the operable directions of the joystick 112 may include one or more, and the present application does not make any specific limitation.

[0036] Among them, a capacitor plate 111 can be set in each operable direction of a joystick 112. Furthermore, in the wearable device 110, for a joystick 112, the number of capacitor plates 111 set in the operable direction of the joystick 112 can be one or more, and this application does not make any specific restrictions.

[0037] The following is an example in which a wearable device 110 includes a joystick 112 and N capacitor plates 111 for explanation.

[0038] In a specific embodiment, there are multiple capacitor plates 111 , and the multiple capacitor plates 111 are arranged around the rocker 112 . The rocker 112 has multiple operable directions, and one capacitor plate is arranged in one operable direction of the rocker.

[0039] For example, the number of the capacitor plates 111 is N, where N is a positive integer, the joystick 112 has N operable directions, and the N capacitor plates 111 are disposed in the N operable directions of the joystick 112 .

[0040] A capacitive plate 111 may be provided in each operable direction of the joystick 112 , and thus the capacitive sensor 110 may detect the actual operating direction of the joystick 112 from the N operable directions of the joystick 112 .

[0041] Among them, the embodiment of the present application can set the number of capacitor plates 111 according to the actual needs of the wearable device (for example, the number of operation instructions corresponding to a joystick). For example, N can be any value such as one, two, or four. The embodiment of the present application does not impose any specific restrictions on the value of N.

[0042] Among them, when N is greater than 1, the areas of the N capacitor plates 111 can be the same or different, and the present application does not impose any specific limitation on this.

[0043] Among them, when N is greater than 1, the shapes of the N capacitor plates 111 can be the same or different, and the present application does not impose any specific limitation on this.

[0044] When N is greater than 1, the N capacitor plates 111 do not contact each other, thereby preventing the N capacitor plates 111 from interfering with each other.

[0045] In this way, in the embodiment of the present application, the joystick 112 can have N operable directions, and the N capacitor plates 111 are arranged one by one in the N operable directions of the joystick 112, so that the capacitive sensor 110 can detect the actual operating direction of the joystick 112 from the N operable directions of the joystick 112.

[0046] For example, in one example, Figure 2 As shown, N is eight, the joystick 112 has eight operable directions, and the eight capacitor plates 111 are respectively arranged in the eight operable directions of the joystick 112, and the eight operable directions are east, south, west, north, southeast, northeast, southwest, and northwest.

[0047] Among them, Figure 2As shown, the eight capacitor plates 111 are respectively arranged in the north direction of the joystick 112, the second capacitor plate 1112 is arranged in the northeast direction of the joystick 112, the third capacitor plate 1113 is arranged in the east direction of the joystick 112, the fourth capacitor plate 1114 is arranged in the southeast direction of the joystick 112, the fifth capacitor plate 1115 is arranged in the south direction of the joystick 112, the sixth capacitor plate 1116 is arranged in the southwest direction of the joystick 112, the seventh capacitor plate 1117 is arranged in the west direction of the joystick 112, and the eighth capacitor plate 1118 is arranged in the northwest direction of the joystick 112.

[0048] In this way, the joystick 112 can have eight operable directions, and the eight capacitor plates 111 are arranged one by one in the east, south, west, north, southeast, northeast, southwest, northwest and other directions of the joystick 112, so that the capacitive sensor 110 can detect the actual operating direction of the joystick 112 from the N operable directions of the joystick 112.

[0049] In order to realize direction recognition of multiple operable directions for a joystick, the capacitive sensor 110 may include multiple capacitors, each of which is composed of one of the multiple capacitor plates and the joystick.

[0050] Among them, multiple capacitors share one rocker as the negative plate of the capacitor.

[0051] The plurality of capacitors are respectively used to detect the actual operation direction of the joystick from the plurality of operable directions of the joystick. One capacitor is used to detect whether one operable direction is the actual operation direction of the joystick.

[0052] For example, the first capacitor plate 1111 and the joystick 112 constitute a first capacitor, and the first capacitor is used to detect whether the actual operating direction of the joystick is towards the north; the second capacitor plate 1112 and the joystick 112 constitute a second capacitor, and the second capacitor is used to detect whether the actual operating direction of the joystick is towards the northeast; and so on, the eighth capacitor plate 1118 and the joystick 112 constitute an eighth capacitor, and the eighth capacitor is used to detect whether the actual operating direction of the joystick is towards the northwest.

[0053] In actual applications, the N capacitor plates 111 can be capacitor plates of the same model and have the same area size. When the joystick 112 is not operated, the distance between the N capacitor plates 111 and the joystick 112 (i.e., the initial distance) can be the same. Furthermore, the initial capacitance of the N capacitors is the same. The same current threshold can be set for the N capacitor plates 111. A unified detection method can be used to detect the actual operating direction of the joystick 112 from the N operable directions of the joystick 112. Due to the unified detection method of the N operable directions, the detection process of the actual operating direction is simpler.

[0054] In this way, the joystick 112 of the embodiment of the present application can have N operable directions, and the N capacitor plates 111 are arranged one by one in the N operable directions of the joystick 112, and the capacitive sensor 110 includes N capacitors composed of N capacitor plates 111 and a joystick 112. The N capacitors can detect the actual operating direction of the joystick 112 from the N operable directions of the joystick 112.

[0055] In a specific example, in order to encapsulate the joystick-related parts of the wearable device into an independent joystick function module, such as Figure 5 As shown, the wearable device 100 may further include a shell 130 having an opening, the first end 112 a of the rocker is located inside the shell 130 , and the second end 112 b of the rocker extends to the outside of the shell 130 through the opening of the shell 130 .

[0056] Among them, the embodiment of the present application can set the shape and size of the shell 130 according to actual needs, and the present application does not limit the specific structure of the shell 130.

[0057] In this way, the embodiment of the present application encapsulates part of the joystick-related circuits in the wearable device 100 into an independent joystick function module through the housing 130, thereby preventing other modules from interfering with the circuits inside the joystick function module.

[0058] In order to facilitate the rocking operation of the rocker 112, the shape of the opening of the housing 130 may be an outwardly expanding structure, as shown in FIG. Figure 5 The shell 130 has a target frame 131, and the target frame 131 is provided with an opening; the target frame 131 has a first surface 131a and a second surface 131b opposite to each other, the first surface 131a faces the first end 112a of the rocker, and the second surface 131b faces the second end 112b of the rocker; the size of the opening on the first surface 131a is smaller than the size of the opening on the second surface 131b.

[0059] In this way, the shape of the opening of the shell 130 expands from the inside to the outside, thereby preventing the rocker 112 from being stuck in the opening when it is shaken, and making the shaking operation of the rocker 112 more convenient.

[0060] For example, Figure 5 As shown, the size of the opening of the housing 130 gradually increases along the direction from the first surface 131 a to the second surface 131 b to form a trapezoidal opening.

[0061] In this way, the trapezoidal opening can prevent the opening on the first surface 131 a from being too large to affect the packaging effect of the rocker function module, and can also expand the opening from the inside to the outside to facilitate the rocking operation of the rocker 112.

[0062] Of course, in other embodiments, the shape of the opening may also be other shapes, and the present application does not impose any specific limitation on this.

[0063] In a specific example, Figure 1 and Figure 5 As shown, in order to set the capacitor plate 111 in the operable direction of the joystick 112, the wearable device 100 can also include a bracket body 120, which is arranged in the shell 130, and the bracket body 120 carries multiple capacitor plates 111; the first end 112a of the joystick is located inside the bracket body 120, and the second end 112b of the joystick extends outside the bracket body 120.

[0064] The support body 120 may have insulating properties, and the inner surface of the support body 120 may be divided into N regions when the support body 120 is unfolded, and each region carries a capacitor plate 111. For example, a flexible printed circuit (FPC) is arranged on the inner surface of the support body 120, and the capacitor plate 111 may be a capacitor film, and the capacitor film may be directly attached to the flexible printed circuit in the N regions.

[0065] For example, taking N as 8, 8 capacitor partitions are designed on the FPC and assembled on a fixed bracket body, such as Figure 3 As shown, the inner surface of the bracket body 120 can be divided into 8 areas in the unfolded state. Figure 2 As shown, the bracket body can be enclosed into an octagonal cube in a normal state, and a capacitor film is pasted on the capacitor partition of each side. The rocker 112 can be set on the central axis of the octagonal cube, so that the capacitor film is respectively located in the east, south, west, north, southeast, northeast, southwest, northwest and other directions of the rocker 112. Among them, the first capacitor plate 1111 is located in the north direction of the rocker 112, the second capacitor plate 1112 is located in the northeast direction of the rocker 112, the third capacitor plate 1113 is located in the east direction of the rocker 112, the fourth capacitor plate 1114 is located in the southeast direction of the rocker 112, the fifth capacitor plate 1115 is located in the south direction of the rocker 112, the sixth capacitor plate 1116 is located in the southwest direction of the rocker 112, the seventh capacitor plate 1117 is located in the west direction of the rocker 112, and the eighth capacitor plate 1118 is located in the northwest direction of the rocker 112.

[0066] In this way, the bracket body 120 of the embodiment of the present application can carry N capacitor plates 111, the first end 112a of the rocker 112 is located inside the bracket body 120, and the second end 112b of the rocker 112 extends outside the bracket body 120, so that the N capacitor plates 111 are respectively located in the N operable directions of the rocker 112.

[0067] In a specific example, Figure 4 and Figure 5 As shown, the identification process of the actual operation direction of the joystick 112 can be: when the second end 112b of the joystick 112 swings southward, the first end 112a of the joystick approaches the first capacitor plate 1111 located in the northward direction of the joystick, thereby changing the capacitance between the first capacitor plate 1111 and the joystick 112, and by detecting that the current value / current change on the first capacitor plate 1111 reaches a certain threshold, it can be determined that the second end 112b of the joystick 112 swings southward. Subsequently, when it is detected that the second end 112b of the joystick 112 swings southward, the corresponding control function can be triggered.

[0068] In practical applications, the wearable device 100 may be a device with a human-computer interaction function, and the wearable device 100 may be used to collect the actual operation direction of the joystick when the user operates the joystick, and perform corresponding control functions based on the actual operation direction of the joystick. The wearable device may be a terminal or other device other than a terminal. For example, the wearable device may be a smart watch, smart glasses, headphones, etc., which are not specifically limited in the embodiments of the present application.

[0069] refer to Figure 6 The wearable device 100 provided in the embodiment of the present application may further include: a controller 200 and a current detection circuit 300 ; the controller 200 is connected to the current detection circuit 300 , and the current detection circuit 300 is connected to the capacitor plate 111 .

[0070] Among them, the current detection circuit 300 can be used to detect the current or current change of the capacitor plate 111. For example, the current detection circuit 300 can detect the current of the capacitor plate 111, and the controller 200 can first obtain the current of the capacitor plate 111 detected by the current detection circuit 300, and determine the current change of the capacitor plate 111 detected by the current detection circuit 300. Alternatively, the current detection circuit 300 can detect the current change of the capacitor plate 111, and the controller 200 can directly obtain the current change of the capacitor plate 111 detected by the current detection circuit 300.

[0071] The controller 200 can be used to determine the actual operation direction of the joystick from the N operable directions of the joystick based on the current changes of the N capacitor plates; and determine the target control instruction based on the actual operation direction of the joystick. Different target control instructions are determined for different actual operation directions of the joystick.

[0072] In this way, the wearable device provided in the embodiment of the present application can identify the actual operation direction of the joystick by detecting the current change of the capacitor plate, and then execute the control instructions corresponding to the actual operation direction of the joystick, using this function to achieve better human-computer interaction.

[0073] In practical applications, for example, the wearable device may be a watch, and the joystick may be a crown of the watch. Specifically, the crown of the watch may be located at the second end 112b of the joystick 112, and a portion of the crown of the watch may be pulled out of the rod body and have the function of a joystick.

[0074] For example, the watch may be a smart watch, such as Figure 7 As shown, the dial of the watch has a display interface 400 , on which there may be a moving icon 401 , and the moving icon 401 is used to indicate the actual operating direction (ie, the shaking direction) of the joystick 112 .

[0075] For example, refer to Figure 4 and Figure 5 When the second end 112b of the rocker 112 swings southward, the first end 112a of the rocker approaches the first capacitor plate 1111 located in the northward direction of the rocker, so that the distance d between the first capacitor plate 1111 and the rocker 112 becomes smaller, and the capacitance between the first capacitor plate 1111 and the rocker 112 changes accordingly. By detecting that the current change on the first capacitor plate 1111 reaches a certain threshold, it can be determined that the second end 112b of the rocker 112 swings southward. Figure 7 As shown, the moving icon 401 is used to indicate that the actual operating direction of the joystick 112 is swinging southward.

[0076] Subsequently, when the second end 112b of the rocker 112 is detected to be swinging downward, the corresponding control function may be triggered to be executed. Figure 8 As shown, 9 shortcut function keys can be displayed on the display interface 400 of the watch, and the southward swing of the second end 112b of the joystick 112 can correspond to selecting the 8th shortcut function key and executing the interface corresponding to the 8th shortcut function key on the display interface.

[0077] In this way, adding a joystick function to the crown of the watch and indirectly controlling various control functions of the watch by shaking the crown greatly optimizes the user experience and improves the playability of the watch.

[0078] Based on the same concept as the wearable device provided in any of the above embodiments, an embodiment of the present application also provides a control method for a wearable device, which is used to control the wearable device provided in any of the above embodiments.

[0079] refer to Figure 9-1 The present application embodiment provides a control method for a wearable device, which is applied to Figure 7 The wearable device provided in the embodiment shown may include: Step 910: when the wearable device includes multiple capacitor plates, obtaining current changes of the multiple capacitor plates; Step 920: determining the actual operation direction of the joystick from the multiple operable directions of the joystick based on the current changes of the multiple capacitor plates; Step 930: Determine the target control instruction based on the actual operation direction of the joystick.

[0080] Among them, the actual operation direction of the joystick is different, and the determined target control instructions are also different.

[0081] According to the control method of the wearable device provided by the embodiment of the present application, when the wearable device includes multiple capacitor plates, the current change of multiple capacitor plates is obtained; based on the current change of the multiple capacitor plates, the actual operation direction of the joystick is determined from the multiple operable directions of the joystick; based on the actual operation direction of the joystick, the target control instruction is determined. In this way, the actual operation direction of the joystick can be identified by detecting the current change of the capacitor plates, and then the control instruction corresponding to the actual operation direction of the joystick is executed. This function is used to achieve better human-computer interaction, improve the operability of the wearable device, and optimize the user experience.

[0082] In a specific embodiment, Figure 9-2 As shown, in the above step 920, based on the current changes of the multiple capacitor plates, determining the actual operation direction of the joystick from the multiple operable directions of the joystick includes: Step 921: determining a target capacitor plate having the largest current change among the multiple capacitor plates based on the current changes of the multiple capacitor plates; Step 922: Determine a target operable direction where a target capacitor plate is located from a plurality of operable directions of the joystick; Step 923: Determine the actual operation direction of the joystick based on the target operable direction where the target capacitor plate is located.

[0083] Among them, it is detected that the current change of the target capacitor plate is the largest, and it can be determined that the distance between the joystick 112 and the target capacitor plate becomes smaller, indicating that the first end of the joystick moves toward the direction close to the target capacitor plate, that is, the first end of the joystick moves toward the operable direction of the target capacitor plate set in the joystick, and then the actual operating direction of the joystick can be determined.

[0084] Among them, the moving direction of the second end of the joystick can be opposite to the moving direction of the first end of the joystick. When the actual operating direction of the joystick is understood as the moving direction of the second end of the joystick, the target capacitor plate can be set in the direction opposite to the operable direction of the joystick and determined as the actual operating direction of the joystick.

[0085] For example, the target capacitor plate is the first capacitor plate 1111. When it is detected that the current change of the first capacitor plate 1111 is the largest, it can be determined that the distance between the joystick 112 and the first capacitor plate 1111 is reduced, indicating that the first end of the joystick moves toward the north, and the second end of the joystick moves toward the south accordingly. Therefore, it can be determined that the actual operating direction of the joystick is south.

[0086] Of course, in other embodiments of the present application, the present application can also determine the actual operation direction of the joystick in other ways, and the present application does not limit the analysis and processing method of the current change of multiple capacitor plates. For example, based on the current change of multiple capacitor plates, M capacitor plates whose current change is greater than a certain threshold value are determined among the multiple capacitor plates, and based on the size of the current change of the M capacitor plates, the weight of each capacitor plate in the M capacitor plates is determined, and based on the weights of the M capacitor plates and the operable directions of the M capacitor plates, the actual operation direction of the joystick is determined.

[0087] In a specific embodiment, after determining the target control instruction based on the actual operation direction of the joystick, the control method of the wearable device provided in the embodiment of the present application may further include: Execute the target control command; display the target interface corresponding to the target control command on the display screen of the wearable device.

[0088] Among them, the actual operation direction of the joystick is different, and the determined target control instructions are also different.

[0089] In this way, after detecting the actual operation direction of the joystick, the corresponding target control instruction is executed, and the target interface corresponding to the target control instruction is displayed on the display screen of the wearable device, which can achieve better human-computer interaction, improve the operability of the wearable device, and optimize the user experience.

[0090] In practical applications, when the wearable device is a watch and the joystick is the crown of the watch, the target control instruction can be used to control the interface functions of the watch. The interface functions may include but are not limited to APP selection, panel switching, interface switching, volume increase and decrease, game playing and other scenarios, which are extremely convenient for users. It improves the operability of the watch functions for users.

[0091] For example, refer to Fig.10 , the present application embodiment provides a control method for a smart watch, which may include: Step 1010: Detecting that the user is shaking the rocker crown; Step 1020: respectively detecting the current changes of eight capacitor plates in eight operable directions of the rocker crown; and determining the actual operation direction of the rocker crown based on the current changes of the eight capacitor plates; Step 1030: Generate and execute a control instruction based on the actual operation direction of the joystick crown; Step 1040: Display the target interface corresponding to the control instruction on the display screen of the watch.

[0092] Among them, the joystick crown refers to the crown with joystick function on the smart watch.

[0093] Among them, the embodiment of the present application can obtain the current change of eight capacitor plates through the MCU (Micro Controller Unit) chip, identify the actual operation direction of the joystick crown based on the current change of the eight capacitor plates, and generate corresponding control instructions based on the actual operation direction of the joystick crown. The control instructions can control the selection of interface functions of the watch.

[0094] In this way, when the user shakes the rocker crown, the change in the current I of the eight capacitor plates is detected respectively, thereby determining the distance between each capacitor plate and the rocker crown, and identifying the actual operation direction of the rocker (i.e., the shaking direction). After this function is implemented, it is extremely convenient for users in scenarios such as watch APP selection, dial switching, interface switching, volume increase and decrease, and game playing, and improves the operability of the watch functions for users.
