DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0032] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0033] The terms "at least one (item)", "at least one of" and the like in the specification and claims of the present application refer to any one, any two or a combination of more than two of the objects included therein. For example, at least one (item) of a, b, and c can be represented by: "a", "b", "c", "a and b", "a and c", "b and c" and "a, b and c", where a, b, and c can be single or multiple. Similarly, "at least two (items)" refers to two or more, and its meaning is similar to that of "at least one (item)".

[0034] The wearable device and device control method provided in the embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0035] Typically, a wearable device (such as an extended reality (eXtended Reality, XR) device) includes an optical display element and a shading component. The shading component may include a fitting component, which is used to fit with the user's face. When the user uses the XR device, the user can first wear the XR device on the user's head. At this time, the user's face fits with the fitting component, and then the user's eyes can view the image displayed by the optical display element through the opening on the shading component. However, since the facial features of different users are different, for example, different users wear different objects on their faces (for example, some users may wear vision correction glasses, etc.), and the shading component of the wearable device is of a single model, after the user wears the XR device on the user's head, the distance between the user's eyes and the optical display element may be too close or too far, resulting in the user being unable to clearly view the image displayed by the optical display element; or, for example, different users have different forehead-zygomatic differences, and the shading component of the wearable device is of a single model, after the user wears the XR device on the user's head, the pressure between the user's face and the fitting component may be too high or too low, for example, the pressure between the forehead of the user's face and the fitting component is too high or too low, resulting in discomfort to the user when wearing the wearable device. Therefore, the wearable device is less convenient to use.

[0036] However, in an embodiment of the present application, the wearable device may include an optical display element, an adjustment component connected to the optical display element (the adjustment component is also communicatively connected to the optical display element), a fitting component for fitting to the user's face (the fitting component is connected to the adjustment component), and a detection component communicatively connected to the optical display element; wherein the adjustment component can be extended or contracted, and during the extension of the adjustment component, the adjustment component drives the optical display element and the fitting component away from each other; during the contraction of the adjustment component, the adjustment component drives the optical display element and the fitting component closer to each other; the detection component is used to detect a first parameter, and the first parameter includes at least one of the following: a first distance between the user's eye and the optical display element, a first pressure between the user's face and the fitting component; the optical display element is used to control the extension or contraction of the adjustment component based on the first parameter when displaying a picture. It can be understood that when the user wears vision correction glasses on his face, the detection member can detect the first distance between the user's eyes and the optical display element, so that the optical display element can control the adjustment component to stretch or shrink based on the first distance when the user may be viewing the picture displayed by the optical display element, so as to increase or decrease the distance between the user's eyes and the optical display element, so that the distance between the user's eyes and the optical display element can meet the needs of the user, thereby reducing the situation where the user cannot clearly view the picture displayed by the optical display element. And / or, when the forehead and cheek difference of the user's face is not compatible with the side of the fitting component used to fit the user's face, the detection member can detect the first pressure between the user's face and the fitting component, so that the optical display element can control the adjustment component to stretch or shrink based on the first pressure when the user may be wearing the optical display element, so as to adjust the shape of the side of the fitting component used to fit the user's face, thereby increasing or reducing the pressure between the user's face and the fitting component, so as to reduce the discomfort of the user when wearing the wearable device. In this way, the convenience of use of the wearable device can be improved.

[0037] Figure 1A and Figure 1B FIG. 1 shows a schematic diagram of the structure of a wearable device provided in an embodiment of the present application. Figure 1A and Figure 1BAs shown, the wearable device provided in the embodiment of the present application may include: an optical display element 11; an adjustment component 12, which is connected to the optical display element 11, and the adjustment component 12 is also communicatively connected to the optical display element 11, and the adjustment component 12 can be stretched or contracted; a fitting component 13, which is used to fit the user's face, and the fitting component 13 is connected to the adjustment component 12; a detection component 14, which is communicatively connected to the optical display element 11, and the detection component 14 is used to detect a first parameter, and the first parameter includes at least one of the following: a first distance between the user's eye and the optical display element 11, and a first pressure between the user's face and the fitting component 13.

[0038] In some embodiments of the present application, the wearable device may include at least one of the following: a virtual reality (VR) device, an augmented reality (AR) device, an extended reality (XR) device, a mixed reality (MR) device, etc. Of course, the wearable device may also include other devices, which are not limited in the embodiments of the present application.

[0039] In some embodiments of the present application, the optical display element 11 is used to display a picture for the user to view. The optical display element 11 can also be called a head display body, a head display end, etc. Of course, the optical display element 11 can also have other names, which are not limited in the embodiments of the present application.

[0040] In some embodiments of the present application, the above-mentioned fitting component 13 may include a frame structure and a buffer structure, wherein the buffer structure is wrapped outside the frame structure, and the buffer structure is used to buffer the pressure between the frame structure and the user's face. The frame structure and the buffer structure are provided with at least two openings, so that when the user fits the user's face to the fitting component 13, the user's eyes can view the image displayed by the optical display element 11 through the at least two openings.

[0041] In some examples, a shading member is wrapped outside the bonding component 13, and the shading member can also be connected to the optical display element 11. The shading member is used to block external light to reduce the influence of external light on the user when viewing the image displayed by the optical display element 11. The above bonding component 13 and the shading member can be referred to as a shading component.

[0042] In some embodiments of the present application, the number of the above-mentioned bonding component 13 may be at least one.

[0043] In some embodiments of the present application, one end of the adjustment component 12 may be fixedly connected to the optical display element 11, or detachably connected. The adjustment component 12 may also be connected to the optical display element 11 through a wire or wireless network communication, so that the adjustment component 12 may be extended or retracted according to the control of the optical display element 11. The other end of the adjustment component 12 may be fixedly connected to the fitting component 13, or detachably connected.

[0044] In some embodiments of the present application, the adjustment component 12 may be located inside the shading member or outside the shading member.

[0045] In some embodiments of the present application, Figure 1A and Figure 1B , the number of the above-mentioned adjustment components 12 is at least two; wherein, at least two adjustment components 12 are evenly distributed between the optical display element 11 and the bonding component 13.

[0046] It should be noted that Figure 1A and Figure 1B In the figure, the number of the adjustment components 12 is 6 for illustration.

[0047] In some embodiments of the present application, a portion of the at least two adjustment components 12 can be connected to a side of a first portion of the fitting component 13, another portion of the at least two adjustment components 12 can be connected to a side of a second portion of the fitting component 13, and another portion of the at least two adjustment components 12 can be connected to a side of a third portion of the fitting component 13.

[0048] The first part, the second part and the third part are parts on one side of the fitting component 13 for fitting with the user's face, and when the user's face is fitted with the fitting component 13, the first part, the second part and the third part are fitted with different facial parts of the user's face. For example, when the user's face is fitted with the fitting component 13, the first part fits with the user's forehead, the second part fits with the user's eye corners, and the third part fits with the middle of the user's face.

[0049] It can be understood that since different parts of the at least two adjustment components 12 can be connected to different parts of the fitting component 13, the distance between the fitting component 13 and the optical display element 11 can be adjusted by controlling the different parts of the adjustment components 12 to extend or contract, so as to adjust the exit pupil distance, so that the adjusted exit pupil distance can be suitable for the user; and / or, the shape of the side of the fitting component 13 that is used to fit the user's face (which can also be understood as the forehead-zygomatic difference) can be adjusted by controlling the different parts of the adjustment components 12 to extend or contract, so that the adjusted side of the fitting component 13 that is used to fit the user's face can adapt to the forehead-zygomatic difference of the user.

[0050] In some embodiments of the present application, when the number of the fitting components 13 is at least two, each adjustment component 12 can be connected to one fitting component 13 respectively.

[0051] Thus, it can be known that since at least two adjustment components can be arranged between the optical display element and the fitting component, the optical display element can control at least part of the at least two adjustment components to extend or contract separately according to needs, so that the side of the fitting component used to fit with the user's face presents a shape that adapts to the user's facial features. Therefore, when the user's face is fitted with the fitting component, the situation where the pressure between the user's face and the fitting component is too high or too low can be reduced, thereby reducing the situation where the user's facial discomfort or the gap between the user's face and the fitting component is large, thereby improving the convenience of use of the wearable device.

[0052] In the embodiment of the present application, during the extension of the adjusting component 12, the adjusting component 12 drives the optical display element 11 and the bonding component 13 away from each other; during the contraction of the adjusting component 12, the adjusting component 12 drives the optical display element 11 and the bonding component 13 toward each other.

[0053] In some embodiments of the present application, the distance between the optical display element 11 and the fitting component 13 can be adjusted by controlling the adjustment component 12 to expand or contract, so as to adjust the pupil distance, so that the adjusted pupil distance can be suitable for the user. And / or, the shape (also understood as the forehead-zygomatic difference) presented on the side of the fitting component 13 that fits the user's face can be adjusted by controlling the adjustment component 12 to expand or contract, so that the adjusted side of the fitting component 13 that fits the user's face can adapt to the forehead-zygomatic difference of the user.

[0054] The specific structure of the adjustment component 12 will be described below by way of example.

[0055] In some embodiments of the present application, Figure 1A and Figure 1B ,like Figure 2As shown, the above-mentioned adjustment component 12 includes: a first structural rod 121, a first end of the first structural rod 121 is connected to the optical display unit 11, and a second end of the first structural rod 121 is provided with a groove 1211; a second structural rod 122, a first end of the second structural rod 122 is connected to the fitting component 13, and a second end of the second structural rod 122 is inserted into the groove 1211; a driving structure 123, and the driving unit 123 is located in the groove 1211.

[0056] In the embodiment of the present application, the second structural rod 122 and the first structural rod 121 are clearance-fitted with each other through the groove 1211 , so that the second structural rod 122 can move in a direction away from or close to the bottom of the groove 1211 .

[0057] In some embodiments of the present application, the first end of the second structural rod 122 may be specifically connected to the frame structure of the fitting component 13 .

[0058] In an embodiment of the present application, the above-mentioned driving structure 123 is used to drive the second structural rod 122 to move in a direction away from the bottom of the groove 1211 so that the adjustment assembly 12 extends; or, to drive the second structural rod 122 to move in a direction close to the bottom of the groove 1211 so that the adjustment group 12 contracts.

[0059] In some embodiments of the present application, the driving unit 123 may be connected to the optical display unit 11 in communication, for example, via a wired communication connection, a wireless network communication connection, etc. The driving unit 123 may include at least one of the following: an electric driving member, an electromagnetic driving member, etc.

[0060] The electric drive member may include a motor, an electric motor, etc. When the electric drive member is powered on, the electric drive member may drive the second structural rod 122 to move in a direction away from or close to the bottom of the groove 1211 according to the control of the optical display unit 11 .

[0061] The electromagnetic drive member may include an electromagnet, an electromagnetic coil, etc. The optical display unit 11 can supply different currents to the electromagnetic drive member so that the electromagnetic drive member can drive the second structural rod 122 to move in a direction away from or close to the bottom of the groove 1211 .

[0062] It can be seen that since the adjustment component can include a first structural rod, a second structural rod and a driving structure, and the second end of the second structural rod can be inserted into the groove of the first structural rod, it can be ensured that the second structural rod can move in a direction away from or close to the bottom of the groove, so that the adjustment component can be accurately controlled to extend or contract by driving the second structural rod to move through the driving structure, thereby improving the accuracy of controlling the extension or contraction of the adjustment component.

[0063] In some embodiments of the present application, Figure 2 ,like Figure 3 As shown, the driving structure 123 includes a driving motor 1231 , one end of which is connected to the bottom of the groove 1211 , and a power output end of the driving motor 1231 is connected to the second end of the second structural rod 122 .

[0064] In an embodiment of the present application, the above-mentioned drive motor 1231 is used to drive the second structural rod 122 to move in a direction away from the bottom of the groove 1211 through the power output end of the drive motor 1231; or, drive the second structural rod 122 to move in a direction close to the bottom of the groove 1211 through the power output end of the drive motor 1231.

[0065] In some embodiments of the present application, the drive motor 1231 can control the motor output end of the drive motor 1231 to extend out of the drive motor 1231 according to the control of the optical display element 11, so that the power output end of the drive motor 1231 can drive the second structural rod 122 to move in a direction away from the bottom of the groove 1211. Alternatively, the motor output end of the drive motor 1231 can be controlled to retract the drive motor 1231, so that the power output end of the drive motor 1231 can drive the second structural rod 122 to move in a direction close to the bottom of the groove 1211.

[0066] It can be seen that since the driving structure can include a driving motor, the second structural rod can be accurately driven to move in a direction away from or close to the bottom of the groove by controlling the movement of the power output end of the driving motor, thereby improving the accuracy of controlling the extension or contraction of the adjusting component.

[0067] In some embodiments of the present application, Figure 3 ,like Figure 4 As shown, the driving structure 123 further includes: a first elastic member 124 , a first end of which is connected to the power output end of the driving motor 1231 , and a second end of which is connected to the second end of the second structural rod 122 .

[0068] In some embodiments of the present application, the first elastic member 124 may be any of the following: a spring, a metal spring, an elastic thermoplastic polyurethane rubber (TPU), an elastic memory alloy, etc. Of course, the first elastic member 124 may also be other elastic members, which is not limited in the embodiments of the present application.

[0069] In some embodiments of the present application, the first elastic member 124 is used to buffer the pressure between the user's face and the fitting component 13 .

[0070] In the embodiment of the present application, since the optical display element 11 may not be able to accurately control the extension or contraction of the adjustment component 12, after controlling the extension or contraction of the adjustment component 12, a certain adjustment component 12 or some adjustment components 12 may be longer or shorter. Therefore, a first elastic member 124 may be provided to buffer the pressure between the user's face and the fitting component 13 through the first elastic member 124, thereby reducing the discomfort caused to the user's face due to a certain adjustment component 12 or some adjustment components 12 being longer or shorter.

[0071] It can be seen that since the first elastic member can be set in the driving structure, the situation where the pressure between the user's face and the fitting component is too high or too low due to the inability of the driving structure to accurately drive the adjustment component can be reduced, thereby improving the ease of use of the wearable device.

[0072] In some embodiments of the present application, Figure 2 ,like Figure 5 As shown, the driving structure 123 includes: a first magnetic member 1232 , which is disposed in the groove 1211 ; and a second magnetic member 1233 , which is disposed at the second end of the second structural rod 122 .

[0073] In some embodiments of the present application, the first magnetic member 1232 is an electromagnetic driving member, and the second magnetic member 1233 is a magnet. Alternatively, the first magnetic member 1232 is a magnet, and the second magnetic member 1233 is an electromagnetic driving member. Alternatively, both the first magnetic member 1232 and the second magnetic member 1233 are electromagnetic driving members.

[0074] In some embodiments of the present application, the first magnetic member 1232 may be disposed at the bottom of the groove 1211 , or at other locations within the groove 1211 .

[0075] In the embodiment of the present application, when a first current is passed through at least one of the first magnetic member 1232 and the second magnetic member 1233, a magnetic attraction force is generated between the first magnetic member 1232 and the second magnetic member 1233, and the magnetic attraction force is used to drive the second structural rod 122 to move in a direction away from the bottom of the groove 1211; or, when a second current is passed through at least one of the first magnetic member 1232 and the second magnetic member 1233, a magnetic repulsion force is generated between the first magnetic member 1232 and the second magnetic member 1233, and the magnetic repulsion force is used to drive the second structural rod 122 to move in a direction close to the bottom of the groove 1211.

[0076] In some embodiments of the present application, the first current may be a positive current or a negative current. The second current may be a negative current or a positive current. The first current and the second current may be opposite. The first current and the second current may be passed from the optical display element 11 to at least one of the first magnetic member 1232 and the second magnetic member 1233.

[0077] It can be seen that since the driving structure can include a first magnetic member and a second magnetic member, and by passing current through the first magnetic member and the second magnetic member, the second structural rod can be accurately controlled to move in a direction away from or close to the bottom of the groove without setting up additional components. Therefore, while ensuring that the second structural rod can be accurately controlled to move in a direction away from or close to the bottom of the groove, the complexity and cost of the driving structure can be reduced.

[0078] In some embodiments of the present application, Figure 5 The above-mentioned adjustment component 12 also includes: a limiting rod 125, a first end of which is connected to the bottom of the groove 1211, and a second end of the limiting rod 125 is facing the second end of the second structural rod 122; wherein the above-mentioned first magnetic member 1232 is arranged on the limiting rod 125.

[0079] In the embodiment of the present application, since the optical display element 11 may not supply current to at least one of the first magnetic member 1232 and the second magnetic member 1233, a limit rod 125 may be provided. In this way, when the optical display element 11 does not supply current to at least one of the first magnetic member 1232 and the second magnetic member 1233, the second end of the second structural rod 122 may contact the second end of the limit rod 125 instead of contacting the bottom of the groove 1211, thereby preventing the second structural rod 122 from being inserted into the first structural rod 121 and causing damage to the bottom of the groove 1211.

[0080] Thus, it can be known that, on the one hand, since a limit rod can be arranged in the groove, it can be avoided that the second end of the second structural rod causes damage to the groove bottom of the groove when the current is not passed through at least one of the first magnetic member and the second magnetic member, thereby improving the durability of the first structural rod. On the other hand, since the first magnetic member can be arranged on the limit rod, the distance between the first magnetic member and the second magnetic member can be made closer, so that passing a current with a smaller current value through the first magnetic member and the second magnetic member can drive the second structural rod to move in a direction away from or close to the groove bottom of the groove, thereby reducing the energy consumption of driving the second structural rod to move.

[0081] In some embodiments of the present application, Figure 5 ,like Figure 6As shown, the driving structure 123 further includes: a second elastic member 1234 , and the second elastic member 1234 is disposed at the second end of the limiting rod 125 .

[0082] In some embodiments of the present application, the second elastic member 1234 may be any of the following: a spring, a metal spring, an elastic TPU, an elastic memory alloy, etc. Of course, the second elastic member 1234 may also be other elastic members, which is not limited in the embodiments of the present application.

[0083] In some embodiments of the present application, the second elastic member 1234 is used to buffer the pressure between the user's face and the fitting component 13 .

[0084] In the embodiment of the present application, since the optical display element 11 may not be able to accurately control the extension or contraction of the adjustment component 12, after controlling the extension or contraction of the adjustment component 12, a certain adjustment component 12 or some adjustment components 12 may be longer or shorter. Therefore, a second elastic member 1234 may be provided to buffer the pressure between the user's face and the fitting component 13 through the second elastic member 1234, thereby reducing the discomfort to the user's face caused by a certain adjustment component 12 or some adjustment components 12 being longer or shorter.

[0085] It can be seen that since a second elastic member can be provided in the driving structure, the situation where the pressure between the user's face and the fitting component is too high or too low due to the driving structure being unable to accurately drive the adjustment component can be reduced, thereby improving the ease of use of the wearable device.

[0086] In some embodiments of the present application, when the detection member 14 is used to detect the first distance, the detection member 14 may include a distance detection unit, and the distance detection unit may include at least one of the following: a distance detection sensor, a distance detection camera, etc. When the detection member 14 is used to detect the first pressure, the detection member 14 may include a pressure detection unit, and may include at least one of the following: a piezoresistor, a pressure sensor.

[0087] In some embodiments of the present application, when the detection member 14 is used to detect the first distance, the detection member 14 can be disposed on the optical display element 11, for example, on a surface of the optical display element 11 close to the bonding component 13. When the detection member 14 is used to detect the first pressure, the detection member 14 can be disposed on the bonding component 13, for example, on a surface of the bonding component 13 close to the bonding component 13.

[0088] In some embodiments of the present application, the number of the detection element 14 may be at least one. The detection element 14 may be disposed on the optical display element 11 and / or disposed on the bonding component 13 .

[0089] It should be noted that Figure 1A and Figure 1B In the figure, the number of the detection components 14 is three, and the three detection components 14 are respectively arranged on the optical display element 11 and the bonding component 13.

[0090] In some embodiments of the present application, Figure 1A and Figure 1B ,like Fig. 7A and Figure 7B As shown, the above-mentioned detection component 14 includes at least one of the following: a distance detection camera 141, which is arranged on the optical display element 11, and the distance detection camera 141 is communicated with the optical display element 11, and the distance detection camera 141 is used to detect a first distance; at least two pressure sensors 142, each pressure sensor 142 is arranged on a surface of the fitting component 13 for fitting with the user's face, each pressure sensor 142 is symmetrical with an adjustment component 12 relative to the fitting component 13, each pressure sensor 142 is communicated with the optical display element 11, and each pressure sensor 142 is used to detect a first pressure.

[0091] It should be noted that Fig. 7A and Figure 7B In the figure, the detection part 14 includes a distance detection camera 141 and six pressure sensors 142. The pressure sensors A1 and A2 are arranged on the other side of the first part of the bonding component 13, the pressure sensors B1 and B2 are arranged on the other side of the second part of the bonding component 13, and the pressure sensors C1 and C2 are arranged on the other side of the third part of the bonding component 13. Fig. 7A In the figure, the adjustment component 12 is located in the shading member, so the adjustment component 12 is not shown.

[0092] In some embodiments of the present application, the distance detection camera 141 may be specifically an eye movement monitoring camera. When the optical display element 11 displays a picture, the distance detection camera 141 may capture multiple images and determine whether the multiple images include the user's eyes. When any of the multiple images includes the user's eyes, the distance detection camera 141 may emit a detection light to the user's eyes and calculate the first distance based on the difference between the time of emitting the detection light and receiving the reflected light of the detection light. The detection light may include infrared light, visible light, etc.

[0093] In some embodiments of the present application, a portion of the at least two pressure sensors 142 may be disposed on the other side of the first portion of the bonding component 13, another portion of the two pressure sensors 142 may be disposed on the other side of the second portion of the bonding component 13, and another portion of the two pressure sensors 142 may be disposed on the other side of the third portion of the bonding component 13.

[0094] Thus, it can be known that, since the detection member can include a distance detection camera, and the distance detection camera is arranged on the optical display element, and the distance detection camera is connected to the optical display element in communication, the first distance can be accurately detected by the distance detection camera, so that the optical display element can accurately obtain the first distance, and then the optical display element can accurately control the adjustment component to stretch or shrink, so that the distance between the user's eye and the optical display element is suitable for the user. And / or, since the detection member can include at least two pressure sensors, and each pressure sensor is arranged on the side of the fitting component for fitting with the user's face, each pressure sensor is symmetrical with an adjustment component relative to the fitting component, and each pressure sensor is connected to the optical display element in communication, therefore, the first pressure of the part where each adjustment component is located can be known by each pressure sensor, so that the optical display element can accurately obtain the first pressure of the part where each adjustment component is located, and then the optical display element can accurately control the adjustment component to stretch or shrink, so that the pressure of the part where each adjustment component is located is suitable for the user. In this way, the convenience of use of the wearable device can be improved.

[0095] In the embodiment of the present application, the optical display element 11 is used to control the expansion or contraction of the adjustment component 12 based on the first parameter when displaying an image.

[0096] In some embodiments of the present application, the optical display element 11 can display an image when in a working state, and control the adjustment component 12 and the detection component 14 to be in a working state, so that the detection component 14 can detect the first parameter, and the optical display element 11 can control the adjustment component 12 to extend or contract based on the first parameter.

[0097] In one scenario, the first parameter includes a first distance, so that the optical display element 11 can control at least part of the adjustment component 12 to extend when the first distance is less than a preset distance, or can control at least part of the adjustment component 12 to contract when the first distance is greater than the preset distance, so as to adjust the exit pupil distance, so that after the at least part of the adjustment component 12 is extended, the adjusted exit pupil distance meets the needs of the user. After the adjustment, if the exit pupil distance still does not meet the needs of the user, the user can input the optical display element 11 so that the optical display element 11 can control at least one of the adjustment components 12 to extend or contract again according to the user's input to adjust the exit pupil distance again.

[0098] In some examples, the optical display element 11 can control the adjustment component 12 connected to one side of the second part of the bonding component 13 to extend when the first distance is less than the preset distance; or, can control the adjustment component 12 connected to one side of the second part of the bonding component 13 to contract when the first distance is greater than the preset distance.

[0099] It can be understood that the above-mentioned preset distance can be considered as a distance that meets the needs of most users. Therefore, when the first distance is different from the preset distance, it can be considered that the distance between the current user's eyes and the optical display element 11 is inappropriate, so that the optical display element 11 can adjust the distance between the user's eyes and the optical display element 11 by controlling at least part of the adjustment component 12 or contracting it, so that the distance between the user's eyes and the optical display element 11 matches the distance that meets the needs of most users.

[0100] In another scenario, the first parameter includes a first pressure, so that the optical display element 11 can first obtain the difference between the first pressures detected by the pressure sensors 142 disposed at different parts of the fitting component 13 (such as the first part, the second part, the third part, etc.), and when the difference is greater than or equal to the preset pressure difference, control the pressure sensors 142 disposed at different parts of the fitting component 13 to extend or contract respectively, so that the shape presented by the side of the fitting component 13 for fitting the user's face (which can also be understood as the forehead-cheek difference) matches the user's face. After adjustment, if the forehead-cheek difference still does not meet the user's needs, the user can input the optical display element 11 so that the optical display element 11 can control at least one of the adjustment components 12 to extend or contract again according to the user's input to adjust the forehead-cheek difference again.

[0101] In some examples, the optical display element 11 may first obtain a difference between a first pressure detected by a pressure sensor 142 disposed at a first portion of the bonding component 13 and a first pressure detected by a pressure sensor 142 disposed at a third portion of the bonding component 13, and when the difference is greater than or equal to a preset pressure difference, control the pressure sensor 142 disposed at the first portion of the bonding component 13 and the pressure sensor 142 disposed at the third portion of the bonding component 13 to extend or contract respectively.

[0102] It can be understood that if the difference between the first pressures detected by the pressure sensors 142 arranged at different parts of the fitting component 13 is greater than or equal to the preset pressure difference, it can be considered that the side of the fitting component 13 used to fit the user's face does not match the forehead-cheek difference of the user's face. Therefore, the pressure sensors 142 arranged at different parts of the fitting component 13 can be controlled to expand or contract respectively so that the side of the fitting component 13 used to fit the user's face matches the forehead-cheek difference of the user's face.

[0103] An embodiment of the present application provides a wearable device, which may include an optical display element, an adjustment component connected to the optical display element (the adjustment component is also communicatively connected to the optical display element), a fitting component for fitting to the user's face (the fitting component is connected to the adjustment component), and a detection component communicatively connected to the optical display element; wherein the adjustment component can be extended or contracted, and during the extension of the adjustment component, the adjustment component drives the optical display element and the fitting component away from each other; during the contraction of the adjustment component, the adjustment component drives the optical display element and the fitting component closer to each other; the detection component is used to detect a first parameter, and the first parameter includes at least one of the following: a first distance between the user's eye and the optical display element, a first pressure between the user's face and the fitting component; the optical display element is used to control the extension or contraction of the adjustment component based on the first parameter when displaying a picture. Since the detection member can detect the first distance between the user's eyes and the optical display element, the optical display element can control the adjustment component to extend or contract based on the first distance to increase or decrease the distance between the user's eyes and the optical display element when the image is displayed, that is, when the user may be viewing the image displayed by the optical display element. Therefore, the distance between the user's eyes and the optical display element can meet the needs of the user, thereby reducing the situation where the user cannot clearly view the image displayed by the optical display element. And / or, since the detection member can detect the first pressure between the user's face and the fitting component, the optical display element can control the adjustment component to extend or contract based on the first pressure to increase or decrease the pressure between the user's face and the fitting component when the image is displayed, that is, when the user may be wearing the optical display element, so that the discomfort of the user when wearing the wearable device can be reduced. In this way, the convenience of use of the wearable device can be improved.

[0104] Of course, in order to facilitate fixing the wearable device to the user's face, the wearable device can also be provided with a fixing on the optical display element 11, so that the user can fix the wearable device to the user's face through the fixing, which will be illustrated by an example below.

[0105] In some embodiments of the present application, Fig. 7A The wearable device provided in the embodiment of the present application may further include: a fixing member 15, which is connected to the optical display element 11; wherein the fixing member 15 is used to fix the wearable device on the user's face.

[0106] In some embodiments of the present application, the fixing member 15 may include at least one of the following: a fixing belt, a fixing hook, a fixing clip, etc.

[0107] In which, when the fixing member 15 includes a fixing belt, both ends of the fixing belt are connected to the optical display element 11, and a fixed space for fixing the user's head can be formed between the fixing belt and the fitting component 13, so that the wearable device can be fixed to the user's face through the fixed space.

[0108] When the fixing member 15 includes fixing hooks, the number of the fixing hooks can be at least two, one part of the fixing hooks is connected to one area of ​​the optical display element, and the other part of the fixing hooks is connected to another area of ​​the optical display element, wherein the one part of the fixing hooks is hung on one facial area of ​​the user's face (for example, one ear), and the other part of the fixing hooks is hung on another facial area of ​​the user's face (for example, another ear), so that the wearable device can be fixed to the user's face.

[0109] In the case where the fixing member 15 includes a fixing clip, the number of the fixing clips can be at least two, one part of the fixing clips is connected to one area of ​​the optical display element, and the other part of the fixing clips is connected to another area of ​​the optical display element, and a clamping area for fixing the user's head can be formed between the one part of the fixing clips and the other part of the fixing clips, so that the wearable device can be fixed to the user's face through the clamping area.

[0110] The device control method provided in the embodiment of the present application can be executed by a device control apparatus, a wearable device, or a functional module or entity in a wearable device. The device control method provided in the embodiment of the present application is described by taking a wearable device executing the device control method as an example.

[0111] Figure 8 FIG. 1 is a flow chart of a device control method provided in an embodiment of the present application. Figure 8 As shown, the device control method provided in the embodiment of the present application may include the following steps 101 and 102.

[0112] Step 101: When an optical display element of a wearable device displays an image, the wearable device obtains a first parameter through a detection element of the wearable device.

[0113] In an embodiment of the present application, the above-mentioned first parameter includes at least one of the following: a first distance between the user's eyes and the optical display element, and a first pressure between the user's face and the fitting component of the wearable device.

[0114] It should be noted that, for the description of how the detection component obtains the first parameter, reference may be made to the specific description in the above embodiment, and the embodiments of the present application will not be repeated here.

[0115] Step 102: The wearable device controls the extension or contraction of an adjustment component of the wearable device based on a first parameter through an optical display element.

[0116] In some embodiments of the present application, the wearable device can control at least part of the adjustment components to extend or contract according to the size relationship between the first parameter and the preset parameter.

[0117] In one scenario, the wearable device can control at least part of the adjustment component to stretch or shrink so as to increase or decrease the distance between the user's eyes and the optical display element.

[0118] In another scenario, the wearable device can control at least one of the partial adjustment components to extend, and control at least one of the partial adjustment components to contract, so as to adjust the shape of a side of the fitting component that is used to fit the user's face.

[0119] The embodiment of the present application provides a device control method, in which the wearable device can obtain a first parameter through a detection part of the wearable device when the optical display element displays a picture, and the first parameter includes at least one of the following: a first distance between the user's eyes and the optical display element, a first pressure between the user's face and the fitting component of the wearable device, and through the optical display element, based on the first parameter, control the extension or contraction of the adjustment component of the wearable device. Because in the case where the optical display element displays a picture, that is, when the user may be viewing the picture displayed by the optical display element, the wearable device can obtain the first distance between the user's eyes and the optical display element through the detection part, and control the extension or contraction of the adjustment component based on the first distance to increase or decrease the distance between the user's eyes and the optical display element, therefore, the distance between the user's eyes and the optical display element can meet the user's needs, thereby reducing the situation where the user cannot clearly view the picture displayed by the optical display element. And / or, when the optical display element displays a picture, that is, when the user may be wearing the optical display element, the wearable device can obtain the first pressure between the user's face and the fitting component of the wearable device through the detection member, and control the adjustment component to stretch or contract based on the first pressure to increase or reduce the pressure between the user's face and the fitting component, thereby reducing the discomfort of the user when wearing the wearable device. In this way, the convenience of use of the wearable device can be improved.

[0120] The following will use different scenarios as examples to illustrate specific solutions for controlling the extension or contraction of the adjustment component of the wearable device.

[0121] In a possible implementation of the present application, the first parameter includes a first distance. Figure 8 ,like Fig. 9As shown, the above step 101 can be specifically implemented by the following step 101a, and the above step 102 can be specifically implemented by the following step 102a or step 102b.

[0122] Step 101a: When the optical display element of the wearable device displays an image, the wearable device obtains a first distance through a distance detection camera of the detection element.

[0123] In some embodiments of the present application, the wearable device can capture multiple images through a distance detection camera and determine whether the multiple images include the user's eyes. If the user's eyes are included in any one of the multiple images, the wearable device can control the distance detection camera to emit detection light to the user's eyes, and calculate the first distance based on the difference between the time of emitting the detection light and receiving the reflected light of the detection light.

[0124] In some examples, the wearable device can first calculate the product of the difference between the time of emitting the detection light and receiving the reflected light of the detection light and the transmission speed of the detection light to obtain a first value, and then determine the ratio of the first value and the constant 2 as the first distance.

[0125] It should be noted that the wearable device can also calculate the first distance in other ways, which is not limited in this embodiment of the present application.

[0126] Step 102a: The wearable device controls the adjustment component to extend through the optical display element when the first distance is less than the preset distance.

[0127] In some embodiments of the present application, the wearable device can control the extension of the adjustment component connected to one side of the second part of the fitting component.

[0128] In an embodiment of the present application, if the first distance is less than the preset distance, it can be considered that the distance between the user's eyes and the optical display element is close. Therefore, the wearable device can control the adjustment component to extend to increase the distance between the user's eyes and the optical display element.

[0129] Step 102b: The wearable device controls the adjustment component to retract through the optical display element when the first distance is greater than the preset distance.

[0130] In some embodiments of the present application, the wearable device can control the extension of the adjustment component connected to one side of the second part of the fitting component.

[0131] In an embodiment of the present application, if the first distance is greater than the preset distance, it can be considered that the distance between the user's eyes and the optical display element is far. Therefore, the wearable device can control the adjustment component to contract to reduce the distance between the user's eyes and the optical display element.

[0132] Thus, it can be known that since the wearable device can accurately obtain the first distance between the user's eye and the optical display element through the distance detection camera, the wearable device can accurately control the extension of the adjustment component through the optical display element to increase the distance between the user's eye and the optical display element when the first distance is less than the preset distance, that is, when the user's eye and the optical display element are closer, so that the user can clearly view the picture displayed by the optical display element. Alternatively, when the first distance is greater than the preset distance, that is, when the user's eye and the optical display element are farther, the adjustment component is accurately controlled to shrink to reduce the distance between the user's eye and the optical display element, so that the user can clearly view the picture displayed by the optical display element. In this way, the ease of use of the wearable device can be improved.

[0133] In some embodiments of the present application, after the wearable device controls the adjustment component of the wearable device to extend or contract, the wearable device can also detect the distance between the user's eyes and the optical display element through a distance detection camera, and control the adjustment component to stop extending or contracting when the distance matches a preset distance. After step 102, the device control method provided in the embodiment of the present application can also include the following steps 201 and 202.

[0134] Step 201: The wearable device obtains a second distance between the user's eyes and the optical display element through a distance detection camera.

[0135] It should be noted that, for the description of the wearable device acquiring the second distance, reference may be made to the specific description of the wearable device acquiring the first distance in the above embodiment, and the embodiments of the present application will not be repeated here.

[0136] Step 202: When the second distance matches the preset distance, the wearable device controls the adjustment component to stop extending or contracting through the optical display element.

[0137] In an embodiment of the present application, if the second distance matches the preset distance, it can be considered that the distance between the user's eyes and the optical display element can meet the user's needs. It can be understood that the user can clearly view the image displayed by the optical display element at this time. Therefore, the wearable device can control the adjustment component to stop extending or contracting through the optical display element.

[0138] In this way, it can be seen that since the wearable device can detect the second distance between the user's eyes and the optical display element again through the distance detection camera after controlling the adjustment component of the wearable device to extend or contract, and when the second distance matches the preset distance, that is, when the distance between the user's eyes and the optical display element can meet the user's needs, the optical display element is used to control the adjustment component to stop extending or contracting. Therefore, it can be avoided that the user is still unable to clearly view the picture displayed by the optical display element due to excessive extension or excessive contraction of the control adjustment component. In this way, the convenience of use of the wearable device can be improved.

[0139] In some embodiments of the present application, after the wearable device controls the adjustment component to stop extending or contracting through the optical display element, the wearable device can record the distance between the user's eyes and the optical display element, so that when the user wears the wearable device next time, the wearable device can directly control the adjustment component to extend based on the distance.

[0140] In another possible implementation of the present application, the at least two adjustment components include a first adjustment component and a second adjustment component, the detection component includes a first pressure sensor and a second pressure sensor, the first pressure sensor is symmetrical with the first adjustment component relative to the fitting component, and the second pressure sensor is symmetrical with the second adjustment component relative to the fitting component; the first parameter includes a first pressure. Figure 8 ,like Fig.10 As shown, the above step 101 can be specifically implemented through the following step 101b, and the above step 102 can be specifically implemented through the following step 102c and step 102d.

[0141] Step 101b: When the optical display element of the wearable device displays an image, the wearable device detects and obtains two first pressures through the first pressure sensor and the second pressure sensor.

[0142] In some embodiments of the present application, the first pressure sensor may be disposed on the other side of the first portion of the bonding component, and the second pressure sensor may be disposed on the other side of the third portion of the bonding component.

[0143] It can be understood that the first pressure detected by the first pressure sensor is the pressure between the forehead of the user's face and the fitting component, and the first pressure detected by the second pressure sensor is the pressure between the mid-face part of the user's face (such as the cheekbone) and the fitting component.

[0144] Step 102c: The wearable device determines, through the optical display element, a pressure difference between a first pressure detected by the first pressure sensor and a first pressure detected by the second pressure sensor.

[0145] In some embodiments of the present application, the pressure difference between the first pressure detected by the first pressure sensor and the first pressure detected by the second pressure sensor can be used to characterize: the shape of the side of the fitting component that is used to fit the user's face (such as the forehead-zygomatic difference).

[0146] Step 102d: When the absolute value of the pressure difference is greater than or equal to the preset pressure difference, the wearable device controls the first adjustment component and the second adjustment component to extend or contract respectively.

[0147] In an embodiment of the present application, if the absolute value of the pressure difference is greater than or equal to the preset pressure difference, it can be considered that the shape of the side of the fitting component that is used to fit the user's face (for example, the forehead-zygomatic difference) does not match the user's face. At this time, the pressure between the side of the fitting component that is used to fit the user's face and the forehead of the user's face may be too large. Therefore, the wearable device can control the first adjustment component and the second adjustment component to extend or contract respectively, so that the shape of the side of the fitting component that is used to fit the user's face (for example, the forehead-zygomatic difference) matches the user's face.

[0148] In some embodiments of the present application, the wearable device can control the first adjustment component to extend and control the second adjustment component to contract; or, can control the first adjustment component to contract and control the second adjustment component to extend.

[0149] Thus, it can be known that since the wearable device can accurately obtain the first pressure between different parts of the user's face and the fitting component through the first pressure sensor and the second pressure sensor, and determine the pressure difference between different parts and the fitting component, the wearable device can accurately control the first adjustment component and the second adjustment component to extend or contract respectively through the optical display element when the absolute value of the pressure difference is greater than or equal to the preset pressure difference, that is, when the shape presented by the side of the user's face that fits (such as the forehead-zygomatic difference) does not match the user's face, so that the shape presented by the side of the user's face that fits matches the user's face, thereby reducing the pressure between the user's face and the fitting component, and thus reducing the discomfort of the user when wearing the wearable device. In this way, the ease of use of the wearable device can be improved.

[0150] In some embodiments of the present application, the above step 102d can be specifically implemented through the following step 102d1 or step 102d2.

[0151] Step 102d1: When the pressure difference is greater than 0, the wearable device controls the first adjustment component to contract and controls the second adjustment component to extend.

[0152] In an embodiment of the present application, if the pressure difference is greater than 0, it can be considered that the pressure between the first part of the fitting component and the forehead of the user's face is larger, while the pressure between the third part of the fitting component and the mid-face part of the user's face (such as the cheekbone part) is smaller. Therefore, the wearable device can control the first adjustment component to contract and control the second adjustment component to extend so that the shape of the side of the fitting component used to fit the user's face matches the user's face.

[0153] In some embodiments of the present application, during the process of controlling the first adjustment component to contract and controlling the second adjustment component to extend, the wearable device can also again determine another pressure difference between the pressure detected by the first pressure sensor and the pressure detected by the second pressure sensor, and when the absolute value of the other pressure difference is less than a preset pressure difference, control the first adjustment component to stop contracting and control the second adjustment component to stop extending.

[0154] Step 102d2: When the pressure difference is less than 0, the wearable device controls the first adjustment component to extend and controls the second adjustment component to contract.

[0155] In an embodiment of the present application, if the pressure difference is less than 0, it can be considered that the pressure between the first part of the fitting component and the forehead of the user's face is relatively small, while the pressure between the third part of the fitting component and the mid-face part of the user's face (such as the cheekbone part) is relatively large. Therefore, the wearable device can control the first adjustment component to extend and control the second adjustment component to contract so that the shape of the side of the fitting component used to fit the user's face matches the user's face.

[0156] In some embodiments of the present application, during the process of controlling the first adjustment component to extend and controlling the second adjustment component to contract, the wearable device can also again determine another pressure difference between the pressure detected by the first pressure sensor and the pressure detected by the second pressure sensor, and when the absolute value of the other pressure difference is less than a preset pressure difference, control the first adjustment component to stop extending and control the second adjustment component to stop contracting.

[0157] As can be seen, since the wearable device can also accurately control the first adjustment component to expand or contract, and control the second adjustment component to contract or expand, according to the magnitude relationship between the pressure detected by the first pressure sensor and the pressure detected by the second pressure sensor, so that the shape of the side of the fitting component that fits the user's face matches the user's face, the pressure between the user's face and the fitting component can be reduced, and thus the discomfort of the user when wearing the wearable device can be reduced. In this way, the convenience of use of the wearable device can be improved.

[0158] In some embodiments of the present application, after the wearable device controls the first adjustment component and the second adjustment component to stop extending or contracting through the optical display element, the wearable device can record the pressure detected by the first pressure sensor and the pressure detected by the second pressure sensor, and when the user wears the wearable device next time, based on the pressure detected by the first pressure sensor and the pressure detected by the second pressure sensor, control the first adjustment component and the second adjustment component to extend or contract respectively until the pressure currently detected by the first pressure sensor matches the recorded pressure detected by the first pressure sensor, and the pressure currently detected by the second pressure sensor matches the recorded pressure detected by the second pressure sensor.
