Description

TECHNICAL FIELD

[0001] The present application relates to the field of terminal equipment, in particular to a wearable device. BACKGROUND

[0002] Benign paroxysmal positional vertigo (BPPV) is a common inner ear balance disorder. It is usually triggered by rapid changes in head position, such as getting up, lying down, turning over, etc. Patients suddenly feel a spinning dizziness. Otolith is a calcium carbonate crystal on the utricle and saccule of the inner ear. Under normal circumstances, the otolith is attached to the otolithic membrane, and its main function is to sense linear acceleration and changes in gravity, thereby helping the human body maintain balance. Head trauma, strenuous exercise, ear disease, etc. can cause the otolith to fall off from its original position, and the fallen otolith may enter the semicircular canal. The semicircular canal is an organ that senses rotational movement. Abnormal movement of the otolith in the semicircular canal stimulates the balance receptors of the inner ear, thereby causing dizziness.

[0003] Patients with BPPV usually need otolith repositioning rehabilitation treatment for cure. In addition to dizziness, the clinical manifestations of BPPV also include nystagmus, which is manifested as the eyes swinging left and right or up and down after the vestibule is stimulated by the otolith. Clinicians often determine the specific position of the otolith of the patient according to the direction of nystagmus to help the patient reposition the otolith. However, the number of professional medical personnel is small, and patients often cannot get timely treatment. In addition, medical personnel observe the nystagmus of patients with the naked eye and make judgments based on experience, but the amplitude of nystagmus movement is slight and the duration is short, and the accuracy of the judgment of medical personnel cannot be guaranteed, and the treatment is difficult. Currently, BPPV can also be treated by large medical equipment. When treating, the patient needs to be fixed on the medical equipment, and a camera device is used to aim at the face of the patient to record the eye movement of the patient, and then a professional medical personnel analyzes the video and judges the condition of the patient, and then controls the head movement of the patient through the machine to perform otolith repositioning operation. The advantage of this method is that the repositioning process is more accurate and standardized, but such medical equipment is bulky, high in cost, low in availability, and does not have autonomous operation, and needs to be guided and assisted by professional medical personnel, so patients still cannot get timely treatment.

[0004] It can be seen that there is a lack of a BPPV treatment method in the prior art that is convenient to operate, high in accuracy, and can provide timely treatment for patients. Invention content

[0005] The wearable device provided by the embodiment of the present application solves the problem that there is a lack of a BPPV treatment method in the prior art that is convenient to operate, high in accuracy, and can provide timely treatment for patients.

[0006] The embodiment of the present application provides a wearable device, comprising a shell, and further comprising a processor, a display assembly and a lens barrel assembly which are installed in the shell, the display assembly is fixedly connected with the lens barrel assembly and is in communication connection with the processor.

[0007] The lens barrel assembly comprises at least one lens barrel, each lens barrel is provided with a lens and a first eye detector, the first eye detector is in communication connection with the processor, and the first eye detector is used for collecting eye movement state information and transmitting the collected eye movement state information to the processor. In the first direction, the display assembly and the first eye detector are respectively arranged on the two sides of the lens, and the display interface of the display assembly faces the lens.

[0008] The wearable device provided by the embodiment of the present application can be worn by a user, for example, can be worn on the head or held in the hand. The processor, the display assembly and the lens barrel assembly are integrated together through the shell, and the wearable device is perfect in function, small in size, portable and high in availability. If the wearable device is used to treat otolithic syndrome, the patient can obtain the device in time, for example, can obtain the device by taking or purchasing independently in a hospital, a community or the like.

[0009] The lens barrel of the lens barrel assembly is provided with a lens and a first eye detector, the display assembly and the first eye detector are respectively arranged on the two sides of the lens, and the display interface of the display assembly faces the lens. The lens is located between the display assembly and the eye of the user, and is used for focusing, so that the user can clearly see the picture on the display interface. The first eye detector is used for collecting the eye movement state information of the user, for example, an eye movement image. The processor analyzes the eye movement state information, for example, can judge whether the user has nystagmus, the type of nystagmus, analyze the position of the otolith according to the type of nystagmus, and how to reset the otolith. The display assembly is used for displaying a picture, for example, the processor can display the nystagmus information, reset action guidance and the like in the form of an image, text, animation and the like on the display interface of the display assembly, for the user to view.

[0010] Therefore, the patient with otolithic syndrome only needs to align the eye with the lens barrel assembly of the wearable device, and the device can monitor and professionally analyze the eye movement state of the patient, generate guidance information on the display interface of the display assembly, and the patient can complete the otolith reset treatment independently according to the guidance information. Compared with the naked eye observation and judgment mode of medical staff, the first eye detector can more accurately capture the subtle movement of the patient's eye, and the analysis and calculation of the processor are also more accurate. Compared with large medical equipment, the wearable device is small in size, low in cost, high in availability, and the patient can complete the reset action independently according to the prompt on the display interface, without the assistance of professional medical staff, so that the patient can obtain the treatment in time.

[0011] As can be seen, the wearable device provided in this application embodiment is easy to operate and highly accurate, and can provide timely treatment for patients with benign paroxysmal positional vertigo (BPPV).

[0012] In one possible implementation, a first eye detector is mounted on the inner wall of each lens barrel. Mounting the first eye detector on the inner wall of the lens barrel prevents it from obstructing the light path and affecting the user's viewing of the display interface.

[0013] In one possible implementation, at least one lens tube includes two lens tubes spaced apart in a second direction. The second direction is perpendicular to the first direction.

[0014] Using the above method, users can place their eyes close to the two lens tubes to view the images inside the lens tubes.

[0015] In one possible implementation, the display component includes two displays spaced apart in a second direction, each of which is mounted inside a separate lens barrel.

[0016] With the above solution, a display screen is installed inside each lens barrel, allowing users to view the image inside the lens barrel with both eyes, resulting in a high level of comfort.

[0017] In one possible implementation, each first eye detector is an eye-tracking camera, and the eye movement state information is image information. The eye-tracking camera can be used to track the nystagmus movements of patients with benign paroxysmal positional vertigo (BPPV).

[0018] In one possible implementation, the wearable device further includes an eye support component and at least one second eye detector. The eye support component is fixedly connected to the housing and is disposed in a first direction on the side of the first eye detector away from the display component. The at least one second eye detector is mounted on the eye support component and is communicatively connected to the processor for collecting vibration information.

[0019] With the above solution, the eye support can directly contact the wearer's eye socket and other parts. The second eye detector is installed on the second eye support. Vibrations of the user's eyes can be transmitted to the second eye detector through the eye support. The second eye detector is used to assist in detecting the user's eye movement state and improve detection accuracy.

[0020] In one possible implementation, the eye support assembly includes two eye support members. When at least one lens barrel includes two lens barrels spaced apart in a second direction, the two eye support members are configured to correspond one-to-one with the two lens barrels.

[0021] At least one second eye detector includes two second eye detectors, which are respectively disposed on two eye supports, and each second eye detector is disposed in a first direction at the end of its respective eye support away from the lens tube assembly.

[0022] According to the scheme, the two second eye detectors are arranged on the two eye supports respectively. The second eye detectors are arranged on the two eye supports, so that the vibration information of the eyes of the user can be collected, and the data reliability is improved.

[0023] In a possible implementation, each second eye detector is a vibration sensor.

[0024] In a possible implementation, the wearable device further includes a face support fixedly connected to the housing.

[0025] According to the scheme, the face support can be used to support the forehead, nose bridge and other positions of the user, so that the comfort of the user when wearing the device is improved.

[0026] In a possible implementation, the wearable device further includes a loudspeaker installed on the housing and in communication connection with the processor. The loudspeaker can be used to issue voice prompts to help the user complete the operation.

[0027] In a possible implementation, the wearable device further includes an inertial measurement unit installed on the housing and in communication connection with the processor.

[0028] According to the scheme, the inertial measurement unit can track the posture change of the user, and determine whether the user completes the reset action.

[0029] In a possible implementation, the wearable device further includes a circuit board installed on the housing, and the processor is integrated on the circuit board.

[0030] In a possible implementation, the wearable device is a head-mounted device. The head-mounted device is convenient to wear, has high integration, and is easy to obtain, and can provide timely and professional treatment for the patient. SUMMARY

The head-mounted device can be, for example, smart glasses, a head-mounted display device with augmented reality (AR), virtual reality (VR), or mixed reality (MR) technology, or a smart helmet, etc. The embodiments of the present application do not limit this.

[0075] Please refer to Figures 1 to 4 , Figure 1 The schematic diagram of the principle structure of the wearable device of the embodiments of the present application is shown in FIG. 1.Figure 2 A perspective view of a wearable device according to an embodiment of the present application; Figure 3 An exploded view of a wearable device according to an embodiment of the present application; Figure 4 A structural view of a housing of a wearable device according to an embodiment of the present application.

[0076] As shown in Figures 1 to 3 , the wearable device 100 includes a housing 1, and further includes a processor 41, a display assembly 5 and a lens barrel assembly 3 (the display assembly 5 is hidden in the lens barrel assembly 3, which can be referred to in detail in Figure 9 ). The housing 1 is the outer shell of the wearable device 100, and is used to mount and protect the internal components of the wearable device 100. The specific structure of the housing 1 is not limited, as shown in Figure 4 , in one possible implementation, the housing 1 can include a front shell 11, a top shell 12, a bottom shell 13, and two side walls 14. The various parts of the housing 1 surround a receiving space, and the housing 1 has an opening 15. The processor 41, the display assembly 5 and the lens barrel assembly 3 are mounted in the receiving space, and a user can view the inside of the housing 1 from the opening 15 of the housing 1. The front shell 11 is arranged opposite the opening 15 in a first direction X, the two side walls 14 are arranged opposite each other in a second direction Y, and the top shell 12 and the bottom shell 13 are arranged opposite each other in a third direction Z. The first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0077] For example, when a user wears the wearable device 100, the opening 15 of the housing 1 faces the user's face, the front shell 11 faces the front of the user, the top shell 12 faces above the top of the user's head, and the bottom shell 13 faces below the bottom of the user's head. In one possible implementation, the housing 1 can also not have the opening 15, as long as the lens barrel 31 of the lens barrel assembly 3 is exposed to the outer surface of the housing 1 for the user to view, which is not limited in the present application.

[0078] As shown in Figures 1 to 3 , in one possible implementation, the wearable device 100 can further include a strap 2, and the two ends of the strap 2 along its extension direction are connected to the two side walls 14 of the housing 1, respectively. The strap 2 can fix the wearable device 100 to the user's head. For example, when a user wears it, the user can pass the head through the gap between the strap 2 and the housing 1, and fix the strap 2 to the back of the head or other parts. In one possible implementation, the strap 2 is rotatably connected to the side walls 14 of the housing 1, so that the angle can be flexibly adjusted when worn, and the wearing comfort is improved. Specifically, the two ends of the strap 2 can be provided with connecting holes 20, and the side walls 14 of the housing 1 can be provided with 141 knobs, and the connecting holes 20 of the strap 2 are sleeved on the corresponding knobs 141 and can rotate relative to the knobs 141. The strap 2 and the side walls 14 of the housing 1 can also be rotatably connected by other means, or can also be directly fixedly connected, which is not limited in the present application.

[0079] In some possible implementation manners, the bandage 2 can be replaced by a glasses leg, and the user can wear the glasses leg on the ear. It should be noted that the above wearing scenarios are merely examples, and the shapes and structures of the components in the drawings do not limit the actual structure of the wearable device.

[0080] As shown in FIG. 1, the wearable device 1 includes a mirror barrel assembly 3, a display assembly 5, a processor 41, and a storage 42.

In one possible implementation manner, the mirror barrel assembly 3 includes two mirror barrels 31, and the user can place the eyes close to the two mirror barrels 31 to view the images in the mirror barrels 31. In some possible implementation manners, the mirror barrel assembly 3 can include only one mirror barrel 31, and the user can view through the single eye.

[0081] Further, the display assembly 5 is fixedly connected with the mirror barrel assembly 3 and is in communication connection with the processor 41. The display assembly 5 is a device capable of generating an optical signal. The display assembly 5 can map the optical signal to the eyes of the user through the mirror barrel 31. In other words, the user can see the text, image, video, and other information on the display assembly 5 through the mirror barrel 31. In use, the user needs to place the eyes close to the mirror barrel 31 of the mirror barrel assembly 3. In one possible implementation manner, the display assembly 5 includes a display screen 51, and the user can directly observe the display interface of the display screen 51. In some possible implementation manners, the display assembly 5 can also include an optical projection device such as a micro projector or the like for directly projecting the optical signal (for example, a light beam) to the retina of the user, and the present application does not limit this. The display assembly 5 has a real interface, that is, an interface for displaying images, for example, a display surface of the display screen 51, and the present application does not limit this.

[0082] The processor 41 can be used for parsing signals, processing data, generating program instructions, coordinating and scheduling processes, etc., and can control the overall operation of the wearable device 100. The display assembly 5 is communicatively connected to the processor 41, and the display assembly 5 can display a picture under the control of the processor 41.

The number of processors 41 in the wearable device 100 is not limited and can be one or more. When the wearable device 100 has multiple processors 41, different processors 41 can integrate different processing units.

[0083] The specific form of the processor 41 is not limited. In one possible implementation, the wearable device 100 further includes a circuit board 4, the circuit board 4 is installed in the shell 1, and the processor 41 is integrated in the circuit board 4. Specifically, the processor 41 can be integrated in a system on a chip (SOC), and then the system on a chip is integrated on the circuit board 4. The circuit board 4 can also be provided with connection circuits, signal interfaces, various functional modules, etc., which are not limited in the present application.

[0084] Those skilled in the art can understand that the specific manner in which the display assembly 5 is communicatively connected to the processor 41 is not limited, and can be wired connection, such as connection through a data line or a data interface. It can also be wireless connection, such as communication through wifi (Wireless Fidelity), Bluetooth, cellular network, etc. In one possible implementation, the connection manner of the display assembly 5 and the processor 41 is wired connection. The shell 1 of the wearable device can be embedded with multiple data transmission lines and data transmission ports inside and outside, for realizing data transmission between the display assembly 5 and the processor 41.

[0085] Please refer to Figures 5 to 9 , Figure 5 for Figure 2 a sectional view in the A-A direction; Figure 6 a schematic diagram of the principle structure of the lens barrel in the wearable device of the present application; Figure 7Fig. 2 is a schematic diagram of a perspective view of a lens barrel of a wearable device according to an embodiment of the present application; Figure 8 Fig. 3 is a schematic diagram of an internal structure of the lens barrel of the wearable device according to an embodiment of the present application; Figure 9 Fig. 4 is a schematic diagram of an exploded structure of a lens barrel assembly of the wearable device according to an embodiment of the present application.

[0086] As shown in Fig. 1, the wearable device according to an embodiment of the present application comprises a housing 1, a lens barrel assembly 3, a display assembly 5, a processor 41, and a power supply 42. Figures 5 to 9 As shown in Fig. 3, each lens barrel 31 is provided with a lens 311 and a first eye detector 312, the first eye detector 312 is in communication connection with the processor 41, and the first eye detector 312 is configured to collect eye movement state information and transmit the collected eye movement state information to the processor 41. In the first direction X, the display assembly 5 and the first eye detector 312 are respectively arranged on the two sides of the lens 311, and the display interface of the display assembly 5 faces the lens 311.

[0087] The first direction X may, for example, be the length direction of the lens barrel 31 (when the lens barrel 31 is in the cylindrical structure shown in the figure, the length direction is the radial direction of the lens barrel 31), or the first direction X may also deviate from the length direction of the lens barrel 31, which is not limited in the present application. For example, when the lens barrel assembly 3 is installed in the housing 1, the first direction X may be parallel to the width direction of the housing 1, the second direction Y may be parallel to the length direction of the housing 1, and the third direction Z may be parallel to the height direction of the housing 1.

[0088] The first eye detector 312 and the processor 41 may be in communication connection through wired or wireless connection, which is not limited in the present application. In one possible implementation, the first eye detector 312 and the processor 41 are in wired connection. The eye movement state information collected by the first eye detector 312 may, for example, be a video recording of the user's eye movement, which is not limited in the present application.

[0089] The lens 311 can appropriately magnify and focus the image on the display interface to adapt to the visual habits of the human eye. As can be understood by those skilled in the art, since the display assembly 5 is very close to the user's eye, the user cannot clearly see the content on the display interface. The lens 311 can focus the light on the retina of the human eye to form a clear image, so that the user can clearly see the content on the display interface. Through the magnification of the lens 311, the user's field of view can also be filled, creating an immersive viewing experience. In addition, the lens 311 also has the functions of magnifying the field of view, correcting optical distortion, correcting chromatic aberration, etc., which are not limited in the present application.

[0090] The wearable device 100 provided by the embodiments of the present application can be worn by a user, for example, can be worn on the head or held in the hand. The processor 41, the display assembly 5 and the lens barrel assembly 3 are integrated together through the shell 1, which is functional, small and portable, and has high availability. If the wearable device 100 is used to treat the vestibular disorder, the patient can obtain the device in time, for example, can obtain the device by taking or purchasing independently in a hospital, a community or the like.

[0091] The lens barrel 31 of the lens barrel assembly 3 is provided with a lens 311 and a first eye detector 312, and the display assembly 5 and the first eye detector 312 are respectively arranged on two sides of the lens 311, and the display interface of the display assembly 5 faces the lens 311. The lens 311 is located between the display assembly 5 and the eye of the user, and is used for focusing to enable the user to see the picture on the display interface. The first eye detector 312 is used to collect the eye movement state information of the user, for example, an eye movement image. The processor 41 analyzes the eye movement state information, for example, can determine whether the user has nystagmus, the type of nystagmus, analyze the position of the otolith according to the type of nystagmus, and how to reset the otolith, and the like. The display assembly 5 is used to display a picture, for example, the processor 41 can display the nystagmus information, reset action guidance and the like in the form of an image, text, animation or the like on the display interface of the display assembly 5, for the user to view.

[0092] Therefore, the patient with the vestibular disorder only needs to align the eye with the lens barrel assembly 3 of the wearable device 100, and the device can monitor and analyze the eye movement state of the patient professionally, generate guidance information on the display interface of the display assembly 5, and the patient can complete the otolith reset treatment independently according to the guidance information. Compared with the naked eye observation and judgment method of the medical staff, the first eye detector 312 can more accurately capture the subtle movement of the eye of the patient, and the analysis and calculation of the processor 41 are also more accurate. Compared with large medical equipment, the wearable device 100 is small in size, low in cost, high in availability, and the patient can complete the reset action independently according to the prompt on the display interface, without the assistance of professional medical staff, so that the patient can obtain the treatment in time.

[0093] It can be seen that the wearable device 100 provided by the embodiments of the present application is convenient to operate and high in accuracy, and can provide timely treatment for the patient with the vestibular disorder.

[0094] It should be noted that the specific type of the first eye detector 312 is not limited. In one possible implementation, the first eye detector 312 is an eye tracking camera, and the eye movement state information is image information. The eye tracking camera can detect the eye movement of the user, such as the eye gaze direction, the blinking operation, the gaze operation, and the like, thereby realizing eye tracking. For example, the eye tracking camera can locate the pupil position of the user by using image processing technology, obtain the pupil center coordinates, and then calculate the gaze point of the user, and further track the movement mode of the pupil. Therefore, the eye tracking camera can be used to track the nystagmus movement of the patient with benign paroxysmal positional vertigo.

[0095] The specific structure of the eye tracking camera is not limited, and for example, can include a lens and a photosensitive element. The lens projects the optical image of the eye of the user onto the photosensitive element, and the photosensitive element converts the optical signal into an electrical signal and sends it to the processor 41 for analysis and processing. In some possible implementations, the eye tracking camera can also cooperate with an infrared device to track the eye movement of the user and comprehensively collect the eye movement information of the user, which is not limited in the present application.

[0096] It should be noted that the specific position of the first eye detector 312 in the lens barrel 31 is not limited. As shown in Figures 5 to 7 one possible implementation, the first eye detector 312 is mounted on the inner wall surface of the lens barrel 31. Mounting the first eye detector 312 on the inner wall surface of the lens barrel 31 can prevent it from blocking the light path and affecting the user's viewing of the display interface. In some possible implementations, the first eye detector 312 can also be mounted on the end surface of the lens barrel 31 or the like, as long as it does not block the user's line of sight and can detect the position of the user's eye, which will not be enumerated here.

[0097] As shown in Figures 1 to 3 one possible implementation, the lens barrel assembly 3 includes two lens barrels 31 arranged at intervals in the second direction Y, and the first eye detector 312 is arranged in each of the two lens barrels 31, so that the eyes of the user can be detected at the same time, and the data of the two eyes can be complementary and calibrated to improve the accuracy. In some possible implementations, only one lens barrel 31 can be provided with the first eye detector 312. Since the movements of the two eyes are usually synchronized, only the movement information of one eye of the user can be detected, thereby saving costs, which is not limited in the present application.

[0098] As shown in Figure 9As shown, in a possible implementation manner, the display assembly 5 includes two display screens 51 arranged at intervals in the second direction Y, and the two display screens 51 are respectively installed in the two barrels 31. With this structure, the display screen 51 is installed in each barrel 31, and the user can watch the picture in the barrel 31 with both eyes, and the comfort is higher. In a possible implementation manner, the display assembly 5 can also be provided with only one display screen 51, and the one display screen 51 is installed in the two barrels 31 at the same time, and the picture on the display screen 51 can be divided into two parts by the split-screen mode, for the user to watch with both eyes, which is not limited in the present application.

[0099] The display screen 51 can be a liquid crystal display (LCD), an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, or a quantum dot light emitting diode (QLED) display screen, which is not limited in the present application.

[0100] It should be noted that the specific structure of the barrel 31, the connection mode of each component to the barrel 31, and the mounting position of each component in the barrel 31 are not limited, which will be illustrated below with reference to the accompanying drawings.

[0101] As shown in FIG. 1, Figures 5 to 8 As shown, in a possible implementation manner, the barrel 31 includes a main body 313, which is a hollow cylindrical structure, for example, a cylinder as shown in the figure, and can also be a square cylinder, a polygonal cylinder, etc., which is not limited in the present application. The lens 311 and the first eye detector 312 are accommodated in the main body 313. The lens 311 and the first eye detector 312 can be fixed to the inner wall of the main body 313 by bonding, clamping, welding, etc.

[0102] As shown in FIG. 1, Figure 7 and Figure 8As shown in FIG. 13, in one possible implementation, the inner wall of the main body 313 has a first boss 3131 and a second boss 3132, the lens 311 is bonded to the first boss 3131, and the first eye detector 312 is bonded to the second boss 3132. The boss can increase the bonding area between the objects, and the bonding is more firm. The number of the first boss 3131 and the second boss 3132 is not limited, and each can be one or more. In one possible implementation, the main body 313 of the lens barrel 31 is provided with a plurality of first bosses 3131 (four first bosses 3131 in one example), the plurality of first bosses 3131 are annularly and spacedly arranged on the inner wall of the main body 313, and the lens 311 is simultaneously bonded to the plurality of first bosses 3131, so that the connection between the lens barrel 31 and the lens 311 is more reliable. In another possible implementation, the main body 313 of the lens barrel 31 is provided with one first boss 3131, which is arranged as an annular boss extending along the circumference of the main body 313.

[0103] As shown in FIG. 13, Figure 5 , Figure 7 , Figure 8 In one possible implementation, the lens barrel 31 can further include a connecting portion 314, the main body 313 is fixedly connected to the connecting portion 314, and the display screen 51 of the display assembly 5 is installed on the connecting portion 314. Specifically, the connecting portion 314 can have a plate-shaped structure, which is fixedly connected to an end face of the main body 313 away from the first eye detector 312. In the first direction X, one face of the connecting portion 314 facing the lens 311 is provided with a third boss 3141, the third boss 3141 is annular and located in the main body 313, and the display screen 51 is clamped in the annular third boss 3141, so as to be fixedly connected to the lens barrel 31. The display screen 51 can also be bonded or welded to the third boss 3141, so as to improve the firmness of the connection. In another possible implementation, a plurality of third bosses 3141 can also be arranged on the connecting portion 314, for example, the plurality of third bosses 3141 can be annularly and spacedly distributed, and the display screen 51 is clamped in the plurality of third bosses 3141, which is not limited in the present application.

[0104] As shown in FIG. 13, Figure 9As shown, in one possible implementation, the lens barrel assembly 3 may further include a connecting rod 315. Each lens barrel 31 has a connecting portion 314 with a connecting hole 3142 that penetrates the connecting portion 314 in the second direction Y. The connecting rod 315 passes through the corresponding connecting hole 3142 on the connecting portion 314 of the two lens barrels 31, thus fixing the two lens barrels 31 together. It should be noted that the number of connecting rods 315 and the number of connecting holes 3142 on the connecting portion 314 are not limited. In another possible implementation, each lens barrel 31's connecting portion 314 has two connecting holes 3142, and the lens barrel assembly 3 includes two connecting rods 315. These two connecting rods 315 fix the lens barrel 31, restricting its degree of freedom, preventing tilting, and making the connection more secure.

[0105] like Figure 4 and Figure 9 As shown, in one possible implementation, the wearable device housing 1 is provided with a locking platform 17, and the end of the connecting rod 315 engages with the locking platform 17 to fix the lens barrel assembly 3 to the housing 1. Specifically, each of the two side walls 14 of the housing 1 is provided with a locking platform 17 corresponding to the number of connecting rods 315. Each locking platform 17 has a groove 171 adapted to the shape of the connecting rod 315. The two ends of each connecting rod 315 respectively mate with the corresponding locking platform 17 on the two side walls 14 and engage in the groove 171, thereby fixing it to the housing 1. The connecting rod 315 can also be further strengthened to the locking platform 17 by means of bonding, welding, etc., which is not limited in this application.

[0106] like Figure 5 As shown, in one possible implementation, the circuit board 4 is mounted on the front shell 11 of the housing 1. Specifically, a mounting platform 110 is provided on the front shell 11, and the circuit board 4 can be fixedly connected to the mounting platform 110 of the front shell 11 by fasteners 81. There is space between the wall of the front shell 11 and the circuit board 4, which is beneficial for heat dissipation of the circuit board. The fasteners 81 can be screws, nuts, bolts, etc., and this application does not limit them. The number of fasteners 81 is not limited. In one possible implementation, the circuit board 4 is a rectangular plate structure, and the mounting platform 110 is set as a ring structure adapted to the shape of the circuit board 4. The four corners of the circuit board 4 are fixed to the mounting platform 110 of the front shell 11 by four fasteners 81 respectively. In some possible implementations, the circuit board 4 can also be soldered to the front shell 11, and this application does not limit it.

[0107] Please see Figure 10 , Figure 10 This is a schematic diagram of the principle structure of the eye support component in the wearable device according to an embodiment of this application.

[0108] like Figures 1 to 3 , Figure 5 , Figure 10As shown, in a possible implementation, the wearable device 100 can further include an eye support assembly 6 fixedly connected to the housing 1 and arranged on the side of the first eye detector 312 away from the display assembly 5 in the first direction X.

[0109] The eye support assembly 6 is configured to support the eyes of the user and facilitate positioning of the lens barrels 31 when the user wears the wearable device. When the user wears the wearable device, the position of the lens barrels 31 can be quickly found according to the position of the eye support assembly 6, and the eye socket and other parts are abutted on the eye support assembly 6, so as to view the inside of the lens barrels 31. The specific structure of the eye support assembly 6 is not limited, and in a possible implementation, the eye support assembly 6 includes two eye support members 61, which are arranged in one-to-one correspondence with the two lens barrels 31, and each eye support member 61 is fixedly connected to the housing 1. The two eye support members 61 can support the eyes of the user and improve the wearing comfort.

[0110] It should be noted that the manner in which the eye support member 61 is fixedly connected to the housing 1 is not limited, and in a possible implementation, the eye support member 61 is fixed to the top shell 12 of the housing 1. Specifically, as shown in Figure 4 and Figure 5 The inner wall of the top shell 12 of the housing 1 is provided with two mounting tables 121, and the two mounting tables 121 are arranged in the second direction Y. The side of each mounting table 121 away from the front shell 11 is recessed inward along the first direction X to form a clamping groove 122. The eye support member 61 includes a body 611 configured to support the eyes of the user and a protruding portion 612 connected to the body 611, and the protruding portion 612 is clamped in the clamping groove 122 of the corresponding mounting table 121, so as to fix the eye support member 61 on the housing 1. In a possible implementation, the clamping groove 122 of the mounting table 121 and the protruding portion 612 of the eye support member 61 can be configured as a data interface, the clamping groove 122 of the mounting table 121 can be in communication connection with the processor 41 through a wiring structure or the like, and various electronic elements (such as the second eye detector 63) in the eye support member 61 can be in communication connection with the processor 41. The eye support member 61 can also be directly fixed on the corresponding lens barrel 31, which is not limited in the present application.

[0111] As shown in Figure 10As shown, in one possible implementation, the wearable device 100 further includes at least one second eye detector 63. The second eye detector 63 is mounted on the eye support component 6 and is communicatively connected to the processor 41 for collecting vibration information. Specifically, the second eye detector 63 can be mounted on the eye support member 61 of the eye support component 6. Since the eye support member 61 is in direct contact with the wearer's eye socket and other parts, the vibration of the user's eyes can be transmitted to the second eye detector 63 through the eye support member 61, thereby assisting in the detection of the user's eye movement state and improving detection accuracy. The number of second eye detectors 63 is not limited. In one possible implementation, at least one second eye detector 63 includes two second eye detectors 63, which are respectively disposed on two eye support members 61. Both eye support members 61 are provided with second eye detectors 63, which can collect vibration information of the user's eyes and improve data reliability.

[0112] The specific form of the second eye detector 63 is not limited. In one possible implementation, the second eye detector 63 is a vibration sensor. The vibration sensor can detect orbital vibrations, assist in the analysis of the ring-shaped nystagmus movement in benign paroxysmal positional vertigo (BPPV), and further improve the accuracy and professionalism of diagnosis and treatment.

[0113] The specific location of the second eye detector 63 is not limited. For example, it can be located inside the eye support 61 (the second eye detector 63 is disposed within the body 611 of the eye support 61), on the end face, bottom, side wall 14, etc., as long as it can detect the user's eye vibrations and does not obstruct the user's view. In one possible implementation, each second eye detector 63 is disposed in the first direction X at the end of its respective eye support 61 away from the lens barrel assembly 3. This position is closer to the user's eye and can detect subtle eye vibrations, resulting in higher detection reliability.

[0114] like Figures 1 to 3 As shown, in one possible implementation, the wearable device 100 further includes a face support 7, which is fixedly connected to the housing 1. The face support 7 can be used to support the user's forehead, bridge of the nose, and other areas, improving the user's wearing comfort. The specific structure of the face support 7 is not limited. In one possible implementation, the face support 7 is a frame structure, which is fixedly connected to the end face of the housing 1 on the side away from the front shell 11. In the first direction X, the side of the frame structure away from the housing 1 is recessed towards the housing 1, allowing the user to fit their face into this recessed part. With this structure, the face support 7 fits the user's face shape more closely, facilitating facial positioning and providing a better wearing experience.

[0115] The method of fixing the facial support 7 to the housing 1 is not limited. For example...Figure 2 and Figure 3 As shown, in one possible implementation, the face support 7 is fixedly connected to the housing 1 by a fastener 82. In the first direction X, a portion of the fastener 82 passes through the face support 7 and the other portion passes through the housing 1, thereby fixing the face support 7 to the housing 1. The fastener 82 can be, for example, a screw, bolt, nut, etc., and this application does not limit this. In one possible implementation, the face support 7 is provided with a hollow structure 71, and the fastener 82 can be accommodated within the hollow structure 71. Using this structure not only reduces the difficulty of drilling holes in the face support 7, but also hides the fastener 82 visually, making the wearable device 100 more aesthetically pleasing.

[0116] like Figure 1 As shown, in one possible implementation, the wearable device 100 may further include a speaker 83, which is mounted on the housing 1 and communicatively connected to the processor 41. Voice prompts can be issued through the speaker 83 to help the user complete related operations. For example, the speaker 83 may remind the user to wear the wearable device in the correct posture and to perform actions such as looking at the lens 31 and turning their head. In another possible implementation, the wearable device 100 may also be equipped with a microphone that can listen to the user's voice. The user can communicate with the wearable device 100 through the microphone and speaker 83 to control the wearable device 100 to perform specific operations. The wearable device 100 may also conduct a medical consultation with the user through voice dialogue; this application does not limit this aspect.

[0117] The specific structure and installation location of the speaker 83 are not limited. In one possible implementation, the speaker 83 is mounted on one side wall 14 of the housing 1 and fixed to the side wall 14 via a data interface snap-fit. With this structure, the speaker 83 can both communicate with the processor 41 via the data interface and be directly fixed to the housing 1 via the data interface, without the need for additional connecting devices. This simplifies the structure of the housing 1, reduces the weight of the wearable device 100, makes it lighter and more comfortable to wear, and improves the user experience.

[0118] like Figure 1As shown, in one possible implementation, the wearable device 100 may further include an Inertial Measurement Unit (IMU) 84. The IMU 84 is mounted on the housing 1 and is communicatively connected to the processor 41. The IMU 84 is a sensor used to detect and measure acceleration and rotational motion, and may include an accelerometer, angular velocity meter (or gyroscope), etc. The accelerometer can detect the magnitude of the acceleration of the wearable device 100 in various directions and can also be used to identify the attitude and orientation changes of the wearable device 100. The gyroscope can be used to determine the motion state of the wearable device 100. Therefore, the IMU 84 can track the user's attitude changes and determine whether the user has completed the reset action. Furthermore, the IMU 84 can also be used to detect whether the user is wearing the wearable device correctly, etc., which is not limited in this application.

[0119] Please see Figures 11 to 13e , Figure 11 This is a schematic diagram of the display interface in a wearable device according to an embodiment of this application; Figure 12 This is a schematic diagram illustrating the working process of the wearable device according to an embodiment of this application; Figure 13a A diagram illustrating the initial posture for a user wearing a wearable device; Figure 13b This is a schematic diagram of horizontal nystagmus. Figure 13c This is a schematic diagram of vertical nystagmus. Figure 13d A diagram illustrating a user wearing a wearable device in a sitting or lying position; Figure 13e This is a diagram illustrating a user wearing a wearable device while lying on their side.

[0120] like Figure 11 As shown, in one example scenario, the display interface of display component 5 can display three types of information: nystagmus type, internal state animation, and professional motion animation. Those skilled in the art will understand that different types of benign paroxysmal positional vertigo (BPPV) cause different nystagmus directions. For example, posterior semicircular canal BPPV often causes vertically upward, slightly torsional nystagmus. Figure 13c Horizontal semicircular canal benign paroxysmal positional vertigo (BPPV) primarily causes nystagmus in the horizontal direction, for example... Figure 13b Displaying the type of nystagmus on the screen helps patients understand their condition. Professional motion animations provide dynamic visual guidance for patients to perform repositioning movements; patients can turn their heads or perform standing exercises based on the animations. Figure 13a ), sitting or lying down (such as Figure 13d ), lying on your side (such as Figure 13e) actions, through which the position of the otolith is changed. The internal state animation refers to the animation of the otolith in the patient's ear, which can be simulated according to the patient's eye state information and body posture, so that the patient can more intuitively see the current position and target position of the otolith, and further judge how to complete the reduction action. The internal state animation can be fitted in real time as the patient's posture changes, helping the patient to complete the otolith reduction.

[0121] It should be noted that, Figure 11 The positions of various information in the display interface in the various embodiments are only schematic and do not represent the actual layout. More or less information can be displayed on the display interface than in the figures, and the present application does not limit this.

[0122] As Figures 12 to 13e indicated, the process of the user wearing the wearable device for self-treatment can include, for example:

[0123] (1) Wear the wearable device. During the wearing process, the inertial measurement unit 84 can be used to detect whether the user's wearing posture is correct. If the wearing is not correct, a voice prompt or other information can be sent to remind the user.

[0124] (2) Sample initialization. For example, it can include clearing the last used data and resetting the eye tracking camera and other elements.

[0125] (3) Detect eye information. The eye information can include the eye movement state information detected by the first eye detector 312 and the vibration information collected by the second eye detector 63.

[0126] (4) Determine whether there is nystagmus movement. This process can be completed by the processor 41. If the result of the judgment is that there is no nystagmus movement, the process can be directly ended. If there is nystagmus movement, the next process is entered.

[0127] (5) Determine the type of nystagmus. For example, determine whether the nystagmus movement is in the vertical direction or the horizontal direction.

[0128] (6) Show guidance information. For example, display the type of nystagmus, internal state animation, and professional action animation display information on the display screen 51.

[0129] (7) Detect the body posture. This process can be completed by the inertial measurement unit 84, for example, detecting the change in the orientation of the device, acceleration data, and the like, and analyzing the patient's posture change in cooperation with the processor 41 to determine whether the patient has completed the action. If the patient's action is incorrect, the patient can be reminded again through the display of the picture on the display screen 51, voice prompts, and the like.

[0130] (8) Determine whether there is nystagmus movement. After the patient completes the guided action, it is necessary to determine again whether there is nystagmus movement. If not, the ear stone reset is completed, the patient has been cured, and the process can be ended. If so, it means that the ear stone reset is not completed, and it is necessary to return to step (5) for treatment again until there is no nystagmus movement.

[0131] It should be noted that the above process is only illustrative, and the actual operation process can include more or fewer steps, which is not limited by the present application.

[0132] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application also intends to include these modifications and variations.
