[0038] The control module determines the user's eye fatigue degree based on the eye status information fed back by the eye fatigue detection module; when it is determined that the fatigue degree reaches a preset anti-fatigue threshold (less than the threshold under the eye fatigue state), the control module determines the eye acupoint position based on the eye surrounding image information fed back by the image acquisition module and the internal pre-stored eye information-acupoint matching database (or a pre-stored acupoint position calculation algorithm); then a control instruction is issued to control the position adjustment structure 221 to make the rotating massage structure 222 accurately correspond to the eye acupoint position (the image acquisition module feeds back the correspondence between the rotating massage structure 222 and the eye acupoint position in real time); then the rotating massage structure 222 starts acupoint massage to relieve eye fatigue.

The eye fatigue detection module is arranged on the first mounting structure 211, and the image acquisition module is arranged on the first mounting structure 211 or / and the second mounting structure 213; three angle adjustment mechanisms 214 are arranged on the first mounting structure 211, and the angle adjustment mechanism 214 and the second mounting structure 213 are respectively provided with acupoint massage modules 22; the acupoint massage module 22 arranged on the angle adjustment mechanism 214 is used to massage the Yuyao acupoint, Zanzhu acupoint or Sizhukong acupoint around the eye; the acupoint massage module 22 arranged on the second mounting structure 213 is used to massage the temple around the eye. Scientific research shows that massaging the key acupoints such as Yuyao, Zanzhu, Sizhukong and temples can effectively relieve eye fatigue.

[0040] In order to ensure the accuracy of acupoint location determination, in this embodiment, there are preferably four image acquisition modules in a massage module, which are used to accurately determine the Yuyao point, Zanzhu point, Sizhukong point and the temple respectively.

[0041] In this embodiment, the position adjustment structure 221 in the acupoint massage module 22 includes a lateral adjustment mechanism 2211 and a vertical adjustment mechanism 2212, and the vertical adjustment mechanism 2212 is arranged on the power part of the lateral adjustment mechanism 2211; the rotary massage structure 222 includes a rotary drive member 2221 fixed on the vertical adjustment mechanism 2212 and a massage ball 2222 connected to the power part of the rotary drive member 2221.

[0042] In this embodiment, the angle adjustment mechanism 214 specifically includes a base 2141 fixed on the first mounting structure 211, a flip frame 2142 hinged on the base 2141, and a telescopic driving member 2143 (preferably a micro electric cylinder or a pneumatic cylinder) for driving the flip frame 2142 to rotate; the fixed end of the telescopic driving member 2143 is hinged on the base 2141, and the telescopic end is hinged to the flip frame 2142; the acupoint massage module 22 is arranged on the side of the flip frame 2142 facing the human face; in the initial state, the flip frame 1422 is approximately horizontal, and the rotating massage structure 222 in the acupoint massage module 22 faces upward; when the angle is adjusted, the rotating massage structure 222 flips toward the direction of the human eye along with the flip frame 2142.

[0043] In some embodiments, the smart head mounted device is a lightweight VR glasses, and the head mounted device body 1 has no rear shell module and middle shell, but only a lens module, temples and a control and display module. For VR glasses, the implementation scheme of the connecting frame 21 is as follows: the first mounting structure 211 includes a first fixing clip 2111 matched with the lens module and a first locking member 2112 inserted on the first fixing clip 2111; the second mounting structure 213 includes a second fixing clip 2131 matched with the temples and a second locking member 2132 inserted on the second fixing clip 2131.

[0044] In some other embodiments, the smart head mounted device is Figure 4The VR head-mounted device shown in the figure has a head-mounted device body 1 having a rear shell module 13 (rear shell and rear shell silicone sleeve), a middle shell 12 and a lens module 14, and strap fixing arms 11 are provided on both sides of the middle shell 12; wherein at least the portion of the shell 12 corresponding to the temple position is made of a flexible silicone material, and the portion of the rear shell or the rear shell silicone sleeve corresponding to the fish waist point, the bamboo point or the bamboo point is made of a flexible silicone material. For this type of VR head-mounted device, the implementation scheme of the connecting frame 21 is as follows: the first mounting structure 211 includes a first fixing clip 2111 matched with the lens module 14 and a first locking member 2112 inserted on the first fixing clip 2111; the second mounting structure 213 includes a second fixing clip 2131 matched with the strap fixing arm 11 and a second locking member 2132 inserted on the second fixing clip 2131. Since the parts corresponding to the eye acupuncture points are made of flexible silicone material, which can be elastically deformed, the massage balls 2222 in the acupuncture point massage module 22 will not affect the massage effect when pressing the flexible silicone onto the acupuncture points for massage.

[0045] In some other embodiments, the smart head-mounted device is a VR head-mounted device, and its head-mounted device body 1 has a rear shell module 13 (rear shell and rear shell silicone sleeve), a middle shell 12 and a lens module 14, and strap fixing arms 11 are provided on both sides of the middle shell 12; however, the middle shell 12 and the rear shell module 13 do not reserve flexible silicone installation positions for eye acupuncture points. For this type of VR head-mounted device, the implementation scheme of the connecting frame 21 is as follows: the first mounting structure 211 includes a first mounting seat detachably connected to the side of the rear shell module 13 facing the face, and the second mounting structure 213 includes a second mounting seat detachably connected to the inner wall of the middle shell 12 facing the temple. Preferably, a magnetic component, Velcro or snap-fit ​​structure is provided between the first mounting seat and the rear shell module 13; a magnetic component, Velcro or snap-fit ​​structure is also provided between the second mounting seat and the inner wall of the middle shell 12.

[0046] In some embodiments, the control module is integrated with the main controller in the head-mounted device body 1. Considering that the integration will increase the amount of calculation and power consumption of the main controller, and reduce the calculation speed and response speed; in this embodiment, the control module is preferably set independently, and is electrically connected to the main controller in the head-mounted device body 1 through a pin connector to achieve data communication and power supply. Figure 5 As shown, the control module in this embodiment includes a storage unit, a judgment unit for determining the current user's eye fatigue degree according to the eye state information fed back by the eye fatigue detection module, an image processing unit for obtaining eye feature parameters according to the eye peripheral image information fed back by the image acquisition module, an acupoint determination unit for determining the eye acupoint position according to the eye feature parameters and a pre-stored eye information-acupoint matching database (or a pre-stored acupoint position calculation algorithm), an instruction sending unit, and a communication unit for communicating with the main controller in the head-mounted device body 1.

[0047] Depend on Figure 6 As shown, the control method implemented based on the above-mentioned eye fatigue prevention and relief device 2 includes:

[0048] S1. The eye fatigue detection module feeds back the user's eye status information to the control module in real time.

[0049] S2. The control module determines the degree of eye fatigue of the user based on the eye status information; when it is determined that there is a risk of fatigue, execute step S3, otherwise, return to execute step S1.

[0050] S3. The control module sends instructions of “close the application” and “play dynamic eye adjustment video” to the main controller in the head-mounted device body 1.

[0051] S4, application closed, dynamic eye adjustment video playing.

[0052] S5. After the playing time reaches the preset time, the dynamic eye adjustment video stops playing; the control module determines the eye acupoint position based on the eye surrounding image information fed back by the image acquisition module and the internally stored eye information-acupoint matching database (or a preset acupoint position calculation algorithm).

[0053] S6. The control module controls the angle adjustment mechanism 214 and the position adjustment structure 221 to perform corresponding actions, so that the rotating massage structure 222 accurately corresponds to the corresponding eye acupuncture point position (positioning reference point) (the image acquisition module provides real-time feedback on the corresponding relationship between the rotating massage structure 222 and the corresponding positioning reference point).

[0054] S7. After accurate correspondence (after the rotating massage structure 222 coincides with the corresponding positioning reference point), the rotating massage structure 222 starts acupoint massage to relieve eye fatigue.

[0055] Although the eye fatigue detection technology is mature and can be easily implemented by those skilled in the art according to the general algorithm, in order to facilitate a deeper understanding of the concept of this embodiment, the working principle of the eye fatigue detection module used in this embodiment is illustrated below, wherein the eye fatigue detection module includes a video acquisition processor. The video acquisition processor is used to collect video images of eye states, extract eye feature images from video images (i.e., dynamic tracking of eye feature images, the extraction algorithm is a general algorithm and is not described here), and extract eye feature values ​​from eye feature images (i.e., eye state information, including eye closure time, blinking frequency / duration, the feature values ​​can be extracted using general algorithms such as spatial analysis method, singular feature value method, feature face method, etc., which are not described here). The judgment unit in the control module judges the degree of fatigue according to the eye feature values ​​(eye state information) and the preset thresholds stored in the storage unit; for example, when it is found that the eye closure duration is greater than the set corresponding preset threshold, the blinking frequency is greater than the set corresponding preset threshold, or / and the blinking duration is greater than the set corresponding preset threshold, it is judged that the current user is at risk of fatigue and needs massage to relieve eye fatigue. In some other embodiments, the eye fatigue detection module can directly and quickly obtain an eye fatigue threshold (i.e., eye status information), and the judgment unit in the control module can judge the degree of fatigue based on the comparison between the feedback eye fatigue threshold and the preset threshold; for example, if the eye fatigue threshold is lower than 7.5%, it is judged that there is no fatigue risk; when the eye fatigue threshold is between 7.5% and 15%, it is judged that there is a fatigue risk; when the eye fatigue threshold is greater than 15%, it is judged that there is a fatigue risk and the fatigue risk coefficient is relatively large.

[0056] In addition, there are many ways to determine the position of eye acupoints; the principle of the eye acupoint position determination method adopted in this embodiment is: the image processing unit in the control module processes the peri-eye image information (RGBD image) fed back by the image acquisition module to obtain eye feature parameters (3D features, such as orbital length, orbital height, eyebrow length and contour, depression and color, etc.); the acupoint determination unit determines the eye acupoint position according to the eye feature parameters and the pre-stored eye information-acupoint matching database (including several facial eye feature information and marked eye acupoint features), that is, the obtained eye feature parameters are compared with the feature parameters stored in the database by a similarity algorithm. If the similarity of the comparison matches the set similarity threshold parameter, the eye acupoint position data (positioning reference point) corresponding to the eye feature of the matched reference face is displayed in the peri-eye image (RGBD) (at this time, the relative position of the positioning reference point and the rotating massage structure 222 is displayed in the peri-eye image fed back to the control module, which is convenient for the subsequent precise adjustment of the position of the rotating massage structure 222). In some other embodiments, the image processing unit in the control module processes the RGBD image information around the eye fed back by the image acquisition module to obtain 3D feature parameters of the eye (orbital length, orbital height, pupil position, eyebrow length and contour, concave and convex areas); the acupoint determination unit determines the eye acupoint position based on the 3D feature parameters of the eye and a pre-stored acupoint position calculation algorithm (this algorithm is a common algorithm in the field of image processing; the algorithm is designed based on the fact that the Yuyao point is directly above the pupil and in the middle of the eyebrow; the Zanzhu point is the concave part of the eyebrow, and the Sizhukong point is the tip of the eyebrow).

[0057] The steps of the method or algorithm described in the embodiments disclosed above can be directly implemented by hardware, a software module executed by a processor, or a combination of the two. The software module can be placed in any other form of storage medium known in the technical field such as an electrically programmable ROM, an electrically erasable programmable ROM, a single-chip microcomputer or a processor. In order to clearly illustrate the interchangeability of hardware and software, the composition and principle of the control module have been generally described in the above description according to the function; for example, the storage unit, the judgment unit, the image processing unit, the acupoint determination unit, the instruction sending unit and the communication unit can be a processing chip integrating an algorithm; or they can be program codes stored in a storage medium; whether these functions are executed in hardware or software depends on the specific application and design constraints of the technical solution. No restrictions are made here.

[0058] In summary, the present invention can not only prevent eye fatigue in advance but also automatically relieve eye fatigue, and has strong versatility, can accurately determine the optimal positions of acupoints to be massaged for different users, improves the automatic relief effect of eye fatigue, and enhances user experience.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
