[0002] At present, head-mounted display devices such as VR glasses and AR glasses have begun to be popularized, and users have certain requirements for the use experience of head-mounted display devices.

[0003] A head-mounted display device generally includes a first display and a second display corresponding to two pupils of a user. However, after wearing the head-mounted display device, the user may have a problem of pupil deviation from the first display and the second display, which reduces the user's use experience. SUMMARY

[0004] Therefore, the present application provides a head-mounted device adjustment method that facilitates alignment of two pupils with a first display and a second display.

[0005] Some embodiments of the present application provide a head-mounted device adjustment method applicable to a head-mounted device including a first display and a second display, including the following steps: a pupil detection step of detecting a pupil of a user after the user wears the head-mounted device; a deviation judgment step of obtaining pupil information detected by a detection device and judging whether the position of the head-mounted device is deviated according to the pupil information, outputting a first instruction when it is judged that the head-mounted device is deviated, and outputting a second instruction when it is judged that the head-mounted device is not deviated; a display guidance step of displaying a guidance picture by the first display and the second display after receiving the first instruction to guide the user to adjust the wearing position of the head-mounted device; a interpupillary distance detection step of detecting the distance between the two pupils of the user after receiving the second instruction; and an adjustment step of setting a first range according to the distance between the two pupils and adjusting the distance between the first display and the second display to the first range.

[0006] The above detects the pupil of the user to judge whether the head-mounted device is deviated, thereby guiding the user to adjust the wearing to enable the pupil to be aligned with the first display and the second display on the head-mounted device as a whole, and further automatically adjusts the distance between the first display and the second display by detecting the distance between the two pupils of the user, so that the first display is aligned with one pupil and the second display is aligned with the other pupil, thereby further improving the range of the user to see the display picture of the first display and the second display and improving the user's use experience.

[0007] In some embodiments, the pupil detection step comprises a first detection step of detecting a distance between a preset measurement point on the head-mounted device and the pupil. The wearing judgment step compares the value of the distance between the measurement point and the pupil with a preset second range, and when the value of the distance between the measurement point and the pupil is outside the second range, it is judged that the user does not wear the head-mounted device, and when the value of the distance between the measurement point and the pupil is within the second range, the controller judges that the user wears the device body and outputs a wearing signal. The second detection step detects the included angle between the pupil and the measurement point after the wearing signal is acquired, and outputs the detected included angle value.

[0008] The above-mentioned first detection step and wearing judgment step are used to judge whether the user wears the head-mounted device by detecting the distance between the pupil and the head-mounted device, which requires fewer factors to be judged and is beneficial to improve the judgment speed. The second detection step can further provide the included angle between the pupil and the measurement point, which is beneficial to subsequent judgment of whether the wearing of the head-mounted device deviates.

[0009] In some embodiments, the pupil information comprises an included angle value between the pupil and a preset measurement point on the head-mounted device.

[0010] In some embodiments, the deviation judgment step comprises acquiring the included angle value and comparing the included angle value with a preset included angle range, when the included angle value is outside the included angle range, it is judged that the position of the head-mounted device deviates, and a first instruction is output, and when the included angle value is within the included angle range, it is judged that the position of the head-mounted device does not deviate, and a second instruction is output.

[0011] The above-mentioned deviation judgment step can judge whether the head-mounted device deviates by comparing the included angle value with the included angle range, which can improve the judgment speed.

[0012] In some embodiments, the guide picture is configured to gradually fade when the wearing position of the head-mounted device is gradually adjusted from the deviated position to the non-deviated position.

[0013] The display of the above-mentioned guide picture can gradually fade during the approach to the non-deviated position, which can meet the expectation of the user during execution and improve the guiding effect.

[0014] In some embodiments, the guide picture comprises a virtual line, and the virtual line is displayed on one side of the head-mounted device relative to the deviated direction of the user.

[0015] The above-mentioned virtual line is displayed on one side of the head-mounted device relative to the deviated direction of the user, which can make the customer more intuitively know the deviated direction and further improve the guiding effect.

[0016] In some embodiments, a preset measurement point is arranged on the head-mounted device, and the measurement point is located on the symmetry line between the first display and the second display. The pupil distance detection step includes: an included angle detection step, detecting a first included angle between a line connecting the measurement point and one of the pupils and the symmetry line between the first display and the second display, and a second included angle between a line connecting the measurement point and the other pupil and the symmetry line between the first display and the second display. A distance detection step, detecting a first distance between the measurement point and one of the pupils, and a second distance between the measurement point and the other pupil. A pupil distance acquisition step, acquiring values of the first included angle, the second included angle, the first distance, and the second distance, and calculating the distance between the two pupils according to the values of the first included angle, the second included angle, the first distance, and the second distance.

[0017] The distance between the two pupils can be calculated by detecting the first included angle, the second included angle, the first distance, and the second distance, so that whether the user wears the device body can be detected, whether the device body is deviated can be detected, and intermediate parameters of the distance between the two pupils can be calculated, avoiding setting too many detection devices, reducing the cost, and improving the compactness of the head-mounted device structure.

[0018] In some embodiments, the adjustment method of the head-mounted device further includes: a re-adjustment step, in response to a re-adjustment instruction, sequentially executing the pupil detection step, the deviation judgment step, the display guidance step, the pupil distance detection step, and the adjustment step.

[0019] The re-adjustment step re-executes the pupil detection step, the deviation judgment step, the display guidance step, the pupil distance detection step, and the adjustment step in an abnormal state, avoiding the need to shut down and restart the head-mounted device every time an abnormality occurs, and improving the user experience.

[0020] In addition, the application also provides a head-mounted device that facilitates the alignment of the two pupils with the first display and the second display.

[0026] The connecting assembly enables the adjusting device to simultaneously adjust the first display and the second display by adjusting the connecting assembly, which improves the speed and convenience of the adjustment and reduces the number of adjusting devices, thereby making the overall structure of the head-mounted device more compact.

[0027] The adjusting method of the head-mounted device in the present application detects the pupil of the user, determines whether the device body is worn in a deviated manner according to the pupil information, outputs a first instruction when the device body is worn in a deviated manner, and outputs a second instruction when the device body is not worn in a deviated manner.

[0086] Also, see Figure 6 and Figure 7 The embodiments of the present application also provide a method for adjusting a head-mounted device, which is suitable for a head-mounted device 100 comprising a first display 21 and a second display 22. For the convenience of understanding, the following embodiments are described with the head-mounted device 100 further comprising a device main body 10, a detection apparatus 30, an adjusting apparatus 40, and a controller. It should be noted that in other embodiments, the subject performing each step is not limited to the device main body 10, the detection apparatus 30, the adjusting apparatus 40, and the controller.

[0087] The method for adjusting a head-mounted device comprises a pupil detection step, a deviation judgment step, a display guidance step, a pupillary distance detection step, and an adjustment step.

[0088] The pupil detection step is that the detection apparatus 30 detects the pupil of the user after the user wears the device main body 10.

[0089] When the head-mounted device 100 is turned on, the detection apparatus 30 starts to detect. When the user does not wear the device main body 10, the detection apparatus 30 cannot detect the pupil of the user. When the user wears the device main body 10, the detection apparatus 30 can detect the pupil of the user.

[0090] In some embodiments, the pupil detection step specifically comprises the following steps:

[0091] The first detection step is that the detection apparatus 30 detects the distance between a preset measurement point T on the head-mounted device 100 and the pupil.

[0092] The preset measurement point T can be arranged on any one or more of the device main body 10, the first display 21, the second display 22, the detection apparatus 30, the adjusting apparatus 40, and the controller.

[0093] In some embodiments, the detection device 30 detects that the measuring point T is at a first distance Z1 from one of the pupils and at a second distance Z2 from the other pupil. The distance values of the measuring point T from the pupils include the value of the first distance Z1 and the value of the second distance Z2.

[0094] The wearing judgment step is that the controller compares the distance values of the measuring point T from the pupils with a preset second range, and judges that the user does not wear the device main body 10 when the distance values of the measuring point T from the pupils are outside the second range, and judges that the user wears the device main body 10 and outputs a wearing signal when the distance values of the device main body 10 from the pupils are within the second range.

[0095] When the device main body 10 is worn, there may be some deviation in the position of the device main body 10 in each wearing, which will cause the distance between the measuring point T and the pupil to deviate in each wearing. The set second range allows the existence of the above deviation, thereby improving the accuracy of detection.

[0096] When comparing the distance values of the measuring point T from the pupils with the preset second range, the second range includes a range corresponding to the first distance Z1 and a range corresponding to the second distance Z2. At the same time, comparing the values of the first distance Z1 and the second distance Z2 can further improve the accuracy of detection.

[0097] The second detection step is that the detection device 30 detects the included angle between the pupil and the measuring point T after obtaining the wearing signal, and outputs the detected included angle value.

[0098] In some embodiments, the measuring point T is set to be located on the symmetry line S between the first display 21 and the second display 22, the included angle between the line connecting the measuring point T and one of the pupils and the symmetry line S between the first display 21 and the second display 22 is a first included angle α1, the included angle between the line connecting the measuring point T and the other pupil and the symmetry line S between the first display 21 and the second display 22 is a second included angle α2, and the included angle values include the value of the first included angle α1 and the value of the second included angle α2.

[0099] Through the first detection step and the wearing judgment step, whether the user wears the device main body 10 is judged by detecting the distance between the pupil and the head-mounted device 100, and the factors needed to be judged are less, which is conducive to improving the judgment speed. Through the second detection step, the included angle between the pupil and the measuring point T can be further provided, which is conducive to subsequent judgment of whether the wearing of the device main body 10 deviates.

[0100] The deviation judgment step is that the controller obtains the pupil information detected by the detection device 30, and judges whether the position of the device main body 10 is deviated according to the pupil information, and outputs a first instruction when it is judged that the device main body 10 is deviated, and outputs a second instruction when it is judged that the device main body 10 is not deviated.

[0101] In some embodiments, the pupil information includes an angle value between the pupils and a preset measuring point T on the head-mounted device 100. The angle value includes a first angle value a1 and a second angle value a2, so that the angle between the two pupils and the measuring point T can be determined, thereby improving the accuracy of detection.

[0102] In some embodiments, the deviation determination step includes: the controller acquires the angle value and compares the angle value with a preset angle range; when the angle value is outside the angle range, the controller determines that the position of the device main body 10 is deviated, and outputs a first instruction; when the angle value is within the angle range, the controller determines that the position of the device main body 10 is not deviated, and outputs a second instruction.

[0103] In some embodiments, the pupil information further includes a first distance value Z1 and a second distance value Z2, and in the deviation determination step, the first distance value Z1 is further compared with a preset first distance Z1 range, and the second distance value Z2 is further compared with a preset second distance Z2 range. When the angle value is outside the angle range, the first distance value Z1 is outside the first distance Z1 range, and the second distance value Z2 is also outside the second distance Z2 range, the controller determines that the position of the device main body 10 is deviated, and outputs a first instruction; when the angle value is within the angle range, the first distance value Z1 is within the first distance Z1 range, and the second distance value Z2 is also within the second distance Z2 range, the controller determines that the position of the device main body 10 is not deviated, and outputs a second instruction. The conditions affecting the result are added when determining, thereby improving the accuracy of the determination.

[0104] Please refer to Figure 4 , Figure 5a and Figure 5b , Figure 4 The schematic diagram of the display device provided by an embodiment of the present application displays a guide picture. Figure 5a The schematic diagram of the deviation of the pupils relative to the device main body provided by an embodiment of the present application. Figure 5b The schematic diagram of the deviation of the pupils relative to the first display 21 and the second display 22 provided by an embodiment of the present application.

[0105] The display guide step is that the first display 21 and the second display 22 display a guide picture after receiving the first instruction, so as to guide the user to adjust the wearing position of the device main body 10.

[0106] When the first display 21 and the second display 22 display the guide picture, the user can adjust the wearing position of the device main body 10 according to the indication of the guide picture, so that the two pupils of the user are aligned with the whole of the first display 21 and the second display 22, which is beneficial to improve the range of the image that the user can see.

[0107] In some embodiments, the guide picture is configured to gradually fade when the wearing position of the device body 10 is gradually adjusted from the deviated position to the non-deviated position. The guide picture disappears when the wearing position of the device body 10 is completely in the non-deviated position.

[0108] In some embodiments, referring to Figure 4 , the guide picture includes a virtual line B displayed on the side of the device body 10 relative to the deviated direction of the user.

[0109] Referring to Figure 3 and Figure 5c , Figure 3 a structural schematic diagram of a head-mounted device provided by an embodiment of the present application. Figure 5c a schematic diagram of the pupil aligning with the first display 21 and the second display 22 provided by an embodiment of the present application.

[0110] The pupil distance detection step is that the detection device 30 detects the distance between the two pupils of the user after receiving the second instruction.

[0111] The detection of the distance between the two pupils by the detection device 30 can be understood as directly detecting the distance between the two pupils, or can be understood as detecting an intermediate parameter that can be used to calculate the distance between the two pupils.

[0112] In some embodiments, the pupil distance detection step includes:

[0113] The included angle detection step is that the detection device 30 detects the first included angle α1 and the second included angle α2.

[0114] The distance detection step is that the detection device 30 detects the first distance Z1 between the measuring point T and one of the pupils, and the second distance Z2 between the measuring point T and the other pupil.

[0115] The pupil distance acquisition step is that the controller acquires the values of the first included angle α1, the second included angle α2, the first distance Z1 and the second distance Z2, and calculates the distance between the two pupils according to the values of the first included angle α1, the second included angle α2, the first distance Z1 and the second distance Z2.

[0116] The distance between the two pupils can be calculated by detecting the first included angle α1, the second included angle α2, the first distance Z1 and the second distance Z2, so the detection device 30 can detect whether the user wears the device body 10, whether the device body 10 is deviated, or an intermediate parameter that can be used to calculate the distance between the two pupils, thereby avoiding setting too many detection devices 30, reducing the cost, and improving the compactness of the structure of the head-mounted device 100.

[0117] In some embodiments, the detection device 30 comprises an eye movement detection component 31 for detecting the first angle a1 and the second angle a2, and a distance detection component 32 for detecting the first distance Z1 and the second distance Z2.

[0118] The adjusting step is that the controller sets a first range according to the distance between the two pupils, and controls the adjusting device 40 to adjust the distance between the first display 21 and the second display 22 to be within the first range. In this way, the first display 21 can be aligned with one pupil of the user, and the second display 22 can be aligned with the other pupil of the user.

[0119] In some embodiments, the adjusting method of the head-mounted device further comprises a readjusting step, in which the pupil detection step, the deviation judgment step, the display guiding step, the interpupillary distance detection step, and the adjusting step are sequentially executed after the controller responds to a readjusting instruction.

[0120] When an abnormality occurs in the adjusting method of the head-mounted device during execution, the user can press a button on the device body 10, and the button outputs a readjusting instruction after being pressed. The user can also make a preset gesture, and the device body 10 outputs a readjusting instruction after the sensor on the device body 10 senses the preset gesture.

[0121] The abnormality can occur in many situations, for example, the controller generates a program error during execution of the adjusting method of the head-mounted device. For another example, a user wears the device body 10, and the adjusting method of the head-mounted device is not executed completely before the user changes to another user wearing the device body 10.

[0122] In summary, the adjusting method of the head-mounted device of the present application detects the pupils of the user through the detection device 30 to determine whether the device body 10 is worn deviated, thereby guiding the user to adjust the wearing to enable the pupils to be aligned with the first display 21 and the second display 22 connected to the device body 10 as a whole. The adjusting method also detects the distance between the two pupils of the user to automatically adjust the distance between the first display 21 and the second display 22, so that the first display 21 is aligned with one pupil, and the second display 22 is aligned with the other pupil. In this way, the range in which the user sees the display of the first display 21 and the second display 22 is further improved, and the user's experience is improved.

[0123] In addition, those skilled in the art of the present technology should recognize that the above embodiments are only used to illustrate the present application, and are not used as a limitation on the present application. Any appropriate changes and variations to the above embodiments within the spirit and scope of the present application are within the scope of the present disclosure.
