When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0027] refer to Figure 1 , is a cross-sectional schematic diagram of a wearable device, the wearable device comprising:

[0028] Ontology 1;

[0029] The ring 2 is located on the body 1; wherein the ring 2 can rotate on the body 1 with the center of the ring 2 as the rotation center;

[0030] The optical sensing component 3 is located in the body 1 and aligned with a partial area of ​​the ring 2, and is used to collect image information of the ring 2;

[0031] The image processing component (not shown) is located in the main body 1 and is electrically connected to the optical sensing component 3, and is used to determine the rotation state of the ring 2 according to the image information; wherein different image information corresponds to different rotation states.

[0032] Wearable devices may include any type of wearable device, including smart watches, smart bracelets, smart glasses and other wearable devices.

[0033] The body 1 is the body of the wearable device, for example, if the wearable device is a smart watch, the body 1 is the body of the smart watch. If the wearable device is a smart bracelet, the body 1 is the bracelet body of the smart bracelet.

[0034] refer to Figure 1 , is a schematic diagram of a wearable device, Figure 1 A body 1 is shown in FIG. Figure 1 The wearable device shown is a watch, and the main body 1 is the watch body.

[0035] The ring 2 is a ring-shaped structure on the body 1, and can rotate on the body 1. The rotation here refers to the rotation on the body 1 with the center of the ring 2 as the rotation center. The direction, angle and speed of rotation can be determined according to actual use requirements. For example, the direction of rotation can include clockwise rotation and counterclockwise rotation. The angle of rotation can be any angle determined according to requirements, which can be 10 degrees, 30 degrees and 60 degrees, etc. The size of the angle is not limited; the speed of rotation can be the speed of rotation according to requirements.

[0036] The size and width of the ring 2 match the body 1 and can be determined according to actual needs. The ring 2 has a width, an inner diameter and an outer diameter, and the width of the ring 2 can be determined by the difference between the outer diameter and the inner diameter. The larger the difference between the outer diameter and the inner diameter, the wider the width of the ring 2, and the smaller the difference between the outer diameter and the inner diameter, the narrower the width of the ring 2.

[0037] refer to Figure 2 , is a schematic diagram of a wearable device, Figure 2 The wearable device shown is a watch, and the wearable device may also include other components, such as a watch strap. The body 1 may also include other components, such as a base, Figure 1 The middle strap is connected to the body 1 via the base.

[0038] refer to Figure 3 , which is a schematic diagram of the relationship between the body 1 and the ring 2, refer to Figure 4 ,for Figure 3 Schematic diagram of the separation between the main body 1 and the ring 2 shown.

[0039] Exemplarily, the wearable device is a watch, and the ring 2 is a detachable bezel. Figure 4 The diagram shown is the diagram after the bezel is removed from the watch body.

[0040] The ring 2 can be located on the surface of the body 1, such as Figures 1 to 3 shown.

[0041] refer to Figure 5 , is a schematic diagram of another circular ring, and the width of the circular ring 2 is represented by L. The wider the width of the circular ring 2, the more conducive it is for the optical sensing component 3 to collect images. The circular ring 2 may also have a thickness, and the thickness may be represented by H.

[0042] The optical sensor assembly 3 is located in the body 1 and can be fixed at a preset position in the body 1, that is, the position of the optical sensor assembly 3 is fixed. The optical sensor assembly 3 is aligned with a partial area of ​​the ring 2, and a surface of the ring 2 faces the optical sensor assembly 3, so that the optical sensor assembly 3 can easily collect image information of the ring 2. The optical sensor assembly 3 is aligned with a portion of the surface of the ring 2, and the image information of the area of ​​the surface aligned with the optical sensor assembly 3 is collected. Exemplarily, the image information of the area in the surface is different.

[0043] Exemplarily, the main body 1 has a preset space therein, and the preset space is used to accommodate the optical sensor component 3 . The preset space can be determined according to actual needs. For example, the optical sensor component 3 is located in the preset space and can collect image information of the ring 2 .

[0044] The size of the portion where the optical sensing component 3 is aligned with the ring 2 can be determined according to actual needs.

[0045] The optical sensor component 3 may have a preset sampling frequency. When the position of the optical sensor component 3 remains unchanged, the optical sensor component 3 can collect image information of the ring 2, and the size of the image collected each time is the same. For example, the image collected each time is an image of X rows of pixels and Y columns of pixels. This makes it easier for the image processing component 4 to determine the rotation state.

[0046] The optical sensor component 3 can collect continuous image information, such as M frames of continuous images, at a preset collection frequency. After the ring 2 rotates, the area of ​​the ring 2 aligned with the optical sensor component 3 changes. Since the image information at each position in the ring 2 is different, the image information collected by the optical sensor component 3 changes. When the ring 2 is fixed, the image information collected by the optical sensor component 3 is the same.

[0047] The model, structure and size of the optical sensor component 3 are not limited, as long as they can collect image information of the ring 2. The format of the image information collected by the optical sensor component 3 is also not limited, and the collected image can be a color image or a grayscale image.

[0048] Exemplarily, the optical sensing component 3 may include an optical sensor.

[0049] refer to Figure 1 , showing a positional relationship between the ring 2 and the optical sensor assembly 3, refer to Figure 5 , also shows the positional relationship between the ring 2 and the optical sensor component 3, where the optical sensor component 3 is located below the ring 2.

[0050] The image processing component is located in the body 1 and is electrically connected to the optical sensing component 3, and is used to determine the rotation state of the ring 2 according to the image information; wherein different image information corresponds to different rotation states.

[0051] The image processing component is a component that can determine the rotation state of the ring 2 according to the image information, and can be a processor. All hardware structures with this function are within the scope of this embodiment. In this embodiment, the hardware structure of the image processing component is used to determine the rotation state. The image processing component is a device in the related art that can determine the rotation state of the ring 2 according to the image information. The process of the image processing component determining the rotation state is not limited and is not an improvement point of the scheme. It can be determined according to the related technology. For example, the corresponding processing is performed according to the processing device inside the image processing component, or the rotation state of the ring 2 is determined in combination with the related processing process.

[0052] The image processing component determines different rotation states according to different image information, that is, different image information corresponds to different rotation states, so the rotation state of the ring 2 can be determined according to the change information of the image information.

[0053] The rotation state may include displacement, rotation angle, rotation speed, etc. relative to the optical sensing component 3 .

[0054] The optical sensing component 3 and the image processing component may be integrated components, for example, they may be two components of an optical tracking sensor (OTS), which is a common sensor for surface detection and can determine the relative movement of the detected surface. The optical tracking sensor may include an optical encoder having an image acquisition function and a function of determining the relative displacement of the captured object relative to the optical tracking sensor based on the captured image.

[0057] Since the optical sensor assembly 3 is located inside the body 1, the influence of external information on the image information of the ring collected by the optical sensor assembly 3 is reduced, thereby improving the stability and accuracy of determining the rotation state of the ring and improving the user experience.

[0058] In one embodiment, there is a light transmission space between the area where the optical sensing component 3 and the ring 2 are aligned, and no other structures exist, thereby reducing the blocking of light by other structures and reducing the impact on the optical sensing component 3 collecting image information.

By setting the through hole on the display screen 102, the influence of the display screen 102 on the image collected by the optical sensor component 3 can be reduced, thereby improving the imaging quality.

[0061] For example, the size and shape of the through hole can be determined according to actual needs, and can be circular, positive, rectangular, etc. The size of the through hole can be larger than the area occupied by the optical sensor component 3 on the main board 103, which can facilitate the optical sensor component 3 to collect images.

The light source 3A and the image collector 3B may be adjacent to each other and located on the same side of the ring 2, so that after the light emitted by the light source 3A is irradiated on the ring 2, the light is reflected by the ring 2 to the image collector 3B, thereby facilitating the image collector 3B to collect image information of the ring 2. Figure 7 As shown, a positional relationship among a light source 3A, an image collector 3B and a ring 2 is shown.

The preset patterns at different positions in the second surface 202 are different, which can facilitate the determination of whether the ring 2 rotates and the rotation state after the rotation according to the collected image information. For the convenience of representation, the preset pattern on the second surface 202 can be recorded as a first preset pattern.

[0073] In one embodiment, the first surface 201 faces away from the body 1. Figure 3 , the first surface 201 of the ring 2 is exposed from the main body 1 .

[0089] In one embodiment, the wearable device further comprises:

[0090] The processor is located in the body 1 and is electrically connected to the optical sensing component 3, and is used to adjust the wearable device according to the rotation state. Different rotation states correspond to different adjustment information.

[0091] The model and parameters of the processor are not limited, and the processor has the function of adjusting the wearable device according to the rotation state. Exemplarily, the rotation state corresponds to the adjustment information one by one, that is, different rotation states correspond to their own adjustment information.

[0092] For example, if you rotate it 10 degrees clockwise, the corresponding adjustment information is to reduce the volume. If you rotate it 10 degrees counterclockwise, the corresponding adjustment information is to increase the volume. If you rotate it 45 degrees clockwise, the corresponding adjustment information is to switch the dial. If you rotate it 90 degrees clockwise, the corresponding adjustment information is to mute mode.

[0105] In one embodiment, a specific application example is provided.

[0106] The wearable watch has a ring, and the ring includes DECO. This kind of watch is a smart watch. It can be based on the needs and occasions of the user. The ring is located on the surface of the watch body. The ring on the surface of the watch can be rotated to switch different functions and interfaces. This design not only improves the practicality and personalization of the watch, but also increases the beauty and fun of the watch. The concept of the wearable watch DECO originates from the current development status of the rotatable field, that is, using a rotating mechanism to change the shape, function or interaction method of an object. At present, the research and application of the rotatable field are mainly concentrated in the following aspects: rotatable displays, rotatable robots, rotatable furniture and rotatable toys. The wearable watch DECO applies the concept and technology of the rotatable field to the traditional wearable device of the watch, bringing a new experience and value to users.

[0107] By using the principle of optical reflection, the rotation of the ring (including DECO) is detected, reducing the influence of the strong magnetic environment on the determination of the rotation state of the ring. This embodiment uses the principle of optical reflection to identify the rotation direction and rotation angle of the watch DECO, increasing the playability and fun of the watch. At the same time, different shortcut functions (conference mode, one-key physical examination, night running mode, etc.) can be set at different angles, and rotating in the menu interface is the rotating crown function (zoom in and out, volume adjustment, etc.).

[0108] This optical solution can solve the inherent external interference problem of the Hall sensor. Because the external magnetic field environment is very complex, the Hall sensor in the watch is very susceptible to interference during actual use, causing the dial to switch randomly. The solution of this embodiment does not need to interact with the outside world, and only needs to ensure the stability of the optical structure to ensure performance.

[0109] The Optical Tracking Sensor (OTS) is a product based on optical navigation technology that can acquire continuous surface images (frames) of the ring through a CMOS image sensor and digitally determine the speed, direction, and amplitude of movement to measure changes in position.

[0110] This solution is based on the OTS principle. The optical tracking sensor is located under the watch ring DECO. By detecting the rotation of DECO, the UI interface is switched and specific functions are adjusted. For example, the functions of switching dials, adjusting volume, adjusting screen brightness, and waking up the screen can be realized.
