Focal length: The distance between the optical center and the focal length of the lens.

Optical power: The reciprocal of the focal length.

Refractive index: When a ray enters another medium with a different refractive index from one medium, the direction of travel changes. This is called the index of refraction in the optical system of the eye.

Dioptre: Represents a unit of refractive power and is represented by D. Specifically, when a parallel ray passes through a refracting material, the refractive power of the refracting material is 1 diopter or 1D at a focal point of 1 m. With respect to a lens, a diopter is a unit of refractive power of a lens. For example, when the focal length of the lens is 1 m, the refractive power of the lens is 1D (diopter).

Angle of view: The angle of view formed by the two sides of the maximum range formed when the objective image of the object to be measured passes through the lens with the lens as the apex is called the angle of view. The angle of view determines the field of view, and the larger the angle of view, the larger the field of view, and the target object outside the angle of view does not exist in the field of view.

Virtual image distance: The distance between the human eye and the virtual image formed behind the lens.

Pupillary distance: The distance between two human pupils.

Eyepiece spacing: The distance between the center points of two eyepieces.

It is fixedly connected to the display screen 322 of 2.

The first display screen 312 can be slide-connected to the first lens barrel 311 in a plurality of ways. For example, referring to FIG. 4, at least one first shoot 313 is placed on the inner wall of the first lens barrel 311 and the first display screen 312 uses at least one first shoot 313. By doing so, it is connected to the first lens barrel 311 and the first display screen 312 can slide in the first chute 313.

In the structure shown in FIG. 4, the first adjusting member can perform the following first adjusting operation: When the first motor 331 of the first adjusting member 33 rotates, the first motor 331 is The first rotary cylinder 333 is rotationally driven, and the first rotary cylinder 333 is rotated to drive the first rotary shaft 332 to be screwed into or unscrewed from the first rotary cylinder 333.

It can be understood that the head-mounted display 300 provided in this embodiment of the present application can adjust the position of the first display screen 312 and the position of the second display screen 322 separately. For visually impaired users, the head-mounted display 300 provided in this embodiment of the present application is a position of a first display screen 312 corresponding to the left eye and a second display screen 322 corresponding to the right eye. By adjusting the positions separately, a clear image can be formed and the user's field of view is not affected as in the prior art, thereby improving the user experience.

Also, the vision of the user's left eye and the vision of the right eye may not be exactly the same. For example, some users have impaired vision in the left eye, but have normal vision in the right eye. Therefore, when the position of the first display screen 312 and the position of the second display screen 322 are adjusted in synchronization, usually only one eye can observe a clear image and the other eye is clear. I can't observe a good image. As a result, the overall visual experience is poor.

The lens barrel 311 and the second lens barrel 321 of the above are brought closer to or separated from each other, and the eyepiece spacing is increased or decreased.

Since the eyepiece spacing must match the user's interpupillary distance and each user has a different interpupillary distance, the eyepiece spacing also differs. The head-mounted display 300 provided in this embodiment of the present application adjusts the eyepiece spacing by rotating a motor to adapt to the actual interpupillary distance of different users and improve the user's visual experience.

FIG. 7 is another schematic structural diagram of the head-mounted display 300. The head-mounted display 300 provided in this embodiment of the present application may further include a visual input unit 35 configured to detect visual information input by the user. The visual information includes at least one of the visual parameter and the interpupillary distance parameter. Visual parameters include left eye visual parameters and / or right eye visual parameters.

Further, the head-mounted display 300 may further include a memory 36 configured to store visual information corresponding to the user's identification information.

The head-mounted display 300 is a first adjusting member 33 or a second adjusting member so as to perform an adjusting operation based on the visual information detected by the visual input unit 35 or based on the visual information stored in the memory 36. It may further include a microprocessor 37 configured to control 34.

Specifically, the microprocessor 37 is configured to control the first adjusting member 33 so as to perform the adjusting operation based on the visual information.
The microprocessor 37 determines the reference value of the first screen-inter-eye distance and / or the reference value of the second screen-inter-eye distance based on the visual information, and the reference value of the first screen-inter-eye distance. The first rotation direction and the first rotation circumference amount of the first motor 331 are determined based on, and / or the second of the second motor 334 based on the reference value of the second screen-to-eye distance. In determining the second rotation direction and the second rotation circumference amount, the first screen-eye distance is the distance between the position of the first display screen 312 and the left eye reference position. The distance between the second screen and the eye is the distance between the position of the second display screen 322 and the reference position of the right eye.
The first adjusting member 33 adjusts the position of the first display screen 312 based on the first rotation direction of the first motor and the first rotation circumference amount, in other words, the first adjusting member 33. However, the above-mentioned first adjustment operation is performed, whereby the distance between the adjusted position of the first display screen 312 and the left eye reference position becomes equal to the reference value of the first screen-eye distance. When,
The first adjusting member 33 adjusts the position of the second display screen 322 based on the second rotation direction of the second motor 334 and the second rotation circumference amount, in other words, the first adjusting member. 33 performs the above-mentioned second adjustment operation, whereby the distance between the adjusted position of the second display screen 322 and the right eye reference position becomes equal to the reference value of the second screen-eye distance.

The amount of rotation circumference of 2 can be obtained.

In a first possible embodiment, the head-mounted display 300 includes a visual input unit 35, and the visual information detected by the input unit 35 includes a left eye visual parameter and / or a right eye visual parameter.

The visual parameters herein may include at least one of myopia and hyperopia. The visual input unit 35 may include at least one of a voice input unit and a manual input unit. In other words, the user can enter visual information in audio or manual format. When the user inputs visual information in a voice format, the visual input unit 35 may specifically include at least one microphone configured to detect the visual information in the voice format input by the user. .. When the user inputs visual information in a manual manner, the visual input unit 35 may specifically include a touch panel, a keyed input panel, a knob-type input panel, and the like. In this way, the user can input accurate left-eye and / or right-eye visual parameters in audio or manual fashion by using the visual input unit 35. For example, see FIG. 8 for a scenario in which the user inputs visual parameters by using the touch panel 40. For example, see Figure 9 for a scenario where the user inputs visual parameters by using voice.

In this embodiment of the present application, when the user starts using the head-mounted display 300, for example, when the head-mounted display 300 is turned on, the head-mounted display 300 gives a visual prompt and / or an auditory prompt. By using it, the user can be further reminded to enter visual information. For example, referring to FIG. 10, the head-mounted display 300 can provide a voice prompt to "enter visual information" by using a loudspeaker (or headset). Alternatively, for example, the head-mounted display 300 may provide a character prompt of "input visual information" by using the display screen of the visual input unit 35 or the touch panel 40. Alternatively, for example, the head-mounted display 300 may brighten the touch panel 40 of the visual input unit 35 to prompt the user to input visual information. See FIG. 11 for a schematic diagram in which the head-mounted display 300 encourages the user by using the touch panel 40.

The microprocessor 37 can determine a reference value for the distance between the display screen and the reference position of the human eye based on the exact visual parameters entered by the user in voice or manual fashion. Hyperopic users correspond to relatively large screen-eye distance and relatively large screen-eye distance reference values, and myopia users have relatively small screen-eye distance and relatively small screen-eye distance. Corresponds to the reference value.

Prior to being worn by the user, the head-mounted display 300 provided in this embodiment of the present application may perform a first adjustment operation, a second adjustment operation, and a third adjustment operation based on visual information. Please note that it is good. In this case, since the user does not wear the head-mounted display, the user cannot know the actual position of the human eye. The screen-eye distance is the distance between the display screen and a preset reference position for the human eye. The reference position of the human eye is usually set at a position 10 mm to 20 mm away from the lens. For example, the left eye reference position may be set at a position 15 mm away from the first lens 314, and the right eye position may be set at a position 15 mm away from the second lens 324.

In one embodiment, the microprocessor 37 is configured to determine a reference value for the first screen-to-eye distance based on the left eye visual parameter, the first based on the left eye visual parameter and Equation 1. It may include determining a reference value for the screen-to-eye distance. The microprocessor 37 may be configured to determine a reference value for the second screen-to-eye distance based on the right eye visual parameter, and the second screen-to-eye distance based on the right eye visual parameter and Equation 1. May include determining a reference value for. Equation 1 can be expressed as:
u _i = 1 / (D _i -1 / k).

In Equation 1, when u _i represents the reference value of the first screen-eye distance, D _i represents the left eye refractive power, and u _i represents the reference value of the second screen-eye distance, D _i represents the right eye refractive power, k represents a constant, and may be specifically related to actual product characteristics such as lens parameters as well as product specifications and size. The unit of refractive power D _i is 1 / meter, 1 / meter is also called diopter represented by D, and 1 diopter corresponds to 100 diopters of vision. Specifically, 100 diopter myopia corresponds to -1dD and 100 diopter hyperopia corresponds to + 1D. In this way, in the screen-eye distance reference value calculated based on Equation 1, the myopia parameter corresponds to the small screen-eye distance reference value, and the hyperopia parameter is the large screen-eye distance reference value. Corresponds to.

Specifically, in some cases, the microprocessor 37 has a screen-to-eye distance reference value (first) based on Equation 1 and the visual parameters (left-eye visual parameter and / or right-eye visual parameter) entered each time by the user. A screen-eye distance reference value and / or a second screen-eye distance reference value) may be calculated.

Alternatively, in another case, the head-mounted display 300 may further include a memory 36, which may store a preset first comparison table. The first comparison table includes the correspondence between the visual parameter and the screen-eye distance, and the correspondence between the screen-eye distance and the visual parameter in the first comparison table is the above-mentioned equation 1. Meet. For example, the visual parameter is myopia. The first comparison table provided in this embodiment of the present application may specifically be Table 1 below.

When determining the reference value for the first screen-eye distance, the microprocessor 37 determines the current distance between the first display screen 312 and the left eye reference position, i.e. the current of the first display screen 312. The current first screen-eye distance is determined based on the position, and the first screen-the difference between the reference value of the eye distance and the current first screen-eye distance is used. The first rotation direction and the first rotation circumference amount of the motor 331 of the motor 331 can be determined.

Each time the head-mounted display 300 is used, the current position of the display screen on the head-mounted display 300 may be a preset position or a saved position after the previous adjustment. Please note. This is not particularly limited herein.

For example, using the first motor 331 as an example, the first screen-to-eye distance, the reference value determined by the microprocessor 37 based on the left eye visual parameter is 25 mm, and the current first one. If the screen-to-eye distance is 20 mm, the first display screen 312 needs to be further adjusted backwards (away from the left eye reference position) by 5 mm, which is expressed as + 5 mm as the adjustment target distance. obtain. The microprocessor 37 may calculate the first rotation circumference of the first motor 331 based on the 5 mm and the first thread pitch of the first rotating shaft 332. Specifically, the first rotation circumference may be a quotient obtained by dividing 5 mm by the first screw pitch. The first screen-eye distance, if the reference value determined by the microprocessor 37 based on the left eye visual parameter is 25 mm and the current first screen-eye distance is 30 mm. The display screen 312 needs to be further adjusted forward by 5 mm (in the direction closer to the left eye reference position), which can be expressed as -5 mm as the adjustment target distance. Also, based on whether the position of the first display screen 312 needs to be adjusted back and forth, the microprocessor 37 will also indicate that the first rotation of the first motor 331 is clockwise or counterclockwise. You can decide if there is one. Specifically, the correspondence between the movement direction of the first display screen 312 and the rotation direction of the first motor 331 is the spiral direction of the threads of the first rotary cylinder 333 and the first rotation shaft 332. is connected with. Similarly, the microprocessor 37 may further determine the second rotation direction and the second rotation circumference amount of the second motor 334.

Further, in a possible embodiment, the memory 36 may further store a preset second comparison table, which is the adjustment target distance of the display screen and the rotation direction and rotation circle of the motor. Includes the correspondence with the circumference. After determining the distance to be adjusted, the microprocessor 37 may determine the direction of rotation and the amount of circumference of the motor by searching the second comparison table.

After the microprocessor 37 determines the first rotation direction and the first rotation circumference amount of the first motor 331, the first adjusting member 33 may perform the first adjustment operation described above. The distance between the adjusted position of the first display screen 312 and the left eye reference position becomes equal to the reference value of the first screen-eye distance. After the microprocessor 37 determines the second rotation direction and the second rotation circumference amount of the second motor 334, the first adjusting member 33 may perform the above-mentioned second adjusting operation. The distance between the adjusted position of the second display screen 322 and the left eye reference position becomes equal to the reference value of the second screen-eye distance.

In this possible embodiment, the head-mounted display determines the screen-to-eye distance reference value based on the accurate visual parameters input by the user, determines the rotation direction and the rotation circumference of the motor, and displays the display screen. The position of the can be adjusted so that a visually impaired user can observe a clear image on the adjusted display screen.

In a second possible embodiment, the head-mounted display 300 may further include a memory 36, where the visual information stored in the memory 36 is a left eye visual parameter and / or a right eye visual parameter corresponding to the user's identification information. including. In this case, the head-mounted display 300 corresponds to the user's identification information, determines the screen-to-eye distance reference value based on the accurate visual parameters stored in the memory 36, and determines the rotation direction and rotation circumference of the motor. Can be determined to adjust the position of the display screen, which allows a visually impaired user to observe a clear image on the adjusted display screen.

In another embodiment, the visual information detected by the visual input unit 35 or the visual information stored in the memory 36 includes a value of the first screen-inter-eye distance and a value of the second screen-inter-eye distance. including. In this possible embodiment, the head-mounted display determines the screen-to-eye distance reference value based on the exact screen-to-eye distance value input by the user, and determines the direction of rotation and the amount of rotation of the motor. The position of the display screen can be adjusted so that a visually impaired user can observe a clear image on the adjusted display screen.

In particular, the first possible embodiment described above can be applied to a scenario in which the user uses the head-mounted display 300 for the first time. In this scenario, the memory 36 does not store the visual information corresponding to the user's identification information. In this case, the user needs to input the left eye visual parameter and / or the right eye visual parameter by using the visual input unit 35. In this case, if the user does not enter a visual parameter, the head-mounted display 300 considers the user's vision to be normal by default, and the visual parameter is a preset normal visual parameter. Another possible embodiment can be applied to scenarios where the user is not new to using the head-mounted display 300. In this scenario, the memory 36 can store the visual information corresponding to the user's identification information, which makes it more effective for the user based on the visual information of the memory 36 the next time the head-mounted display 300 is used. Adjustments can be made to the user without having to re-enter visual information.

Further, when the visual information detected by the visual component 35 or the visual information stored in the memory 36 includes the interpupillary distance parameter, the microprocessor 37 performs a second adjustment operation based on the visual information. It may be further configured to control the adjusting member 34, specifically, the microprocessor 37 has a third rotation direction and a third rotation circumference of the third motor 343 based on the interpupillary distance parameter. Includes determining. The second adjusting member 34 is configured to perform the above-mentioned third adjusting operation based on the third rotation direction of the third motor 343 and the third rotation circumference amount, thereby performing the first eyepiece. The adjusted distance between the lens and the second eyepiece is equal to the interpupillary distance parameter.

The method of determining the third rotation direction and the third rotation circumference of the third motor 343 used by the microprocessor 37 is the first rotation direction of the first motor 331 used by the microprocessor 37. And the same as the method of determining the first rotation circumference. Details are not described again herein. The difference between the interpupillary distance parameter and the current eyepiece spacing may be similar to the adjustment target distance described above.

The head-mounted display provided in this embodiment of the present application is a memory-stored exact interpupillary distance parameter based on the exact interpupillary distance parameter entered by the user or corresponding to the user's identification information. Based on, the direction of rotation and the amount of rotation of the motor can be determined and the positions of the two eyepieces can be adjusted so that the adjusted position of the eyepieces adapts to the user's current interpupillary distance. Being able to understand that it enhances the user's visual experience.

Further, the head-mounted display 300 provided in this embodiment of the present application may further include an identifier input unit 39 configured to input user identification information.

The iris recognition component and the face recognition component may specifically include a camera.

In the second possible embodiment described above, when the identifier input unit 39 is used to detect the user's identification information, the head-mounted display 300 matches the user's identification information and is stored in the memory 36. The adjustment operation may be performed based on the information.

Also, in this embodiment of the present application, when the user starts using the head-mounted display 300, for example, when the power of the head-mounted display 300 is turned on, the head-mounted display 300 has a visual prompt and / or an auditory sense. You can further remind the user to enter the identification information by using the target prompt. For example, the head-mounted display 300 may prompt the user to "enter identification information" by using voice. Alternatively, referring to, for example, FIG. 12, when the head-mounted display 300 includes the touch panel 40, the head-mounted display 300 may prompt the user to "enter identification information" by using the touch panel 40.

Further, after adjusting the position of the display screen or the eyepiece spacing, the head-mounted display 300 may further trigger the prompt information to notify the user that the display screen position / eyepiece spacing has been adjusted. .. Prompt information herein may include visual and / or auditory prompts. For example, prompt information may include, or another type of prompt information. This is not particularly limited herein.

For example, referring to FIG. 13, after adjusting the position of the display screen (for example, the first display screen 312), the head-mounted display 300 displays “display screen position adjusted”, “adjustment completed”, and so on. Alternatively, characters such as visual prompt information such as "ok" may be displayed. For example, referring to FIG. 14, after adjusting the eyepiece spacing, the head-mounted display 300 may display the visual prompt information "eyepiece spacing adjusted" on at least one display screen. For example, after adjusting the position of the display screen, the head-mounted display 300 may display the actual distance between the adjusted position of the display screen and the position of the human eye on the display screen. For example, after adjusting the eyepiece spacing, the head-mounted display 300 may display the adjusted eyepiece spacing on at least one display screen. For example, after adjusting the position of the display screen / eyepiece spacing, the head-mounted display 300 may provide a voice prompt saying "adjustment completed". For example, referring to FIG. 15, after adjusting the position of the first display screen 312, the head-mounted display 300 may provide a voice prompt saying "the position of the first display screen has been adjusted". For example, after adjusting the position of the display screen / eyepiece spacing, the head-mounted display 300 may provide a “tick” voice prompt. For example, after adjusting the position of the display screen / eyepiece spacing, the head-mounted display 300 can simultaneously display the prompt information "adjustment completed" on the display screen and make a "click" sound. For example, after adjusting the position / eyepiece spacing of the display screen, the head-mounted display 300 may notify the user that the position / eyepiece spacing of the display screen has been adjusted by vibration. There may also be other possible prompt formats not listed herein.

Furthermore, after the user wears the head-mounted display 300, the actual position of the human eye and the reference position of the human eye may differ slightly due to the tightness of the wearing or individual differences, or the user's vision. Parameters may change slightly. After the head-mounted display 300 adjusts the position of the display screen based on the accurate visual information of the user, the image observed by the user on the display screen may not be particularly clear. In this case, the user may fine-tune the position of the display screen by triggering the instruction information.

In a possible embodiment, the head-mounted display 300 provided in this embodiment of the present application may further include a mounting detection unit 310 and an instruction input unit 38. The attachment detection unit 310 may be configured to detect whether the terminal 30 is already attached by the user. The instruction input unit 38 is input by the user when the attachment detection unit 310 detects that the terminal 30 is already attached by the user, and instructs the user to adjust the left eye visual parameter and / or the right eye visual parameter. It may be configured to detect the first instructional information used.

The microprocessor 37 determines the first adjustment value and / or the second adjustment value based on the first instruction information, and the first adjustment value is the adjustment value of the first screen-to-eye distance. , The second adjustment value is the adjustment value of the second screen-to-eye distance, and the fourth rotation direction and the fourth rotation circumference amount of the first motor 331 are set based on the first adjustment value. It may be further configured to determine and / or determine the fifth rotation direction and fifth rotation circumference of the second motor 334 based on the second adjustment value.

The first adjusting member 33 adjusts the position of the first display screen 312 based on the fourth rotation direction of the first motor 331 and the fourth rotation circumference amount, and / or the second motor 334. It may be further configured to adjust the position of the second display screen 322 based on the fifth rotation direction and the fifth rotation circumference.

The visual parameter adjustment amplitude indicated by the user by using the first instructional information may be relatively small. Specifically, the instruction input unit 38 may include at least one of the voice instruction input unit and the attitude instruction input unit. The voice instruction input unit may specifically include a microphone configured to detect the user's voice instruction. The attitude indicator input unit may specifically include a camera configured to detect the user's attitude indicator. Posture input components herein can detect posture instruction information used by the user to direct adjustment of left eye visual parameters and / or right eye visual parameters, eg, movement of the user's eyes. It can be information and movement information of the user's head. Further, the instruction input unit 38 may further include a plurality of sensors specifically configured to detect user instruction information.

For example, referring to FIG. 16, the user may instruct the left eye myopia diopter to increase by 1 diopter and the right eye hyperopia diopter to decrease by 3 diopters by using voice. Alternatively, for example, the memory 36 may further store preset adjustment steps. For example, the visual parameter is 1 diopter, and the user can be instructed to increase the left eye myopia diopter, in other words, to increase the left eye myopia diopter by 1 diopter by using voice. Alternatively, for example, the user can turn his head to the left to indicate that the left eye visual parameter needs to be adjusted, and turn his head up to indicate that the user's visual parameter needs to be increased. The user can turn his head to the right to indicate that the right eye visual parameters need to be adjusted, and turn his head down to indicate that the user's visual parameters need to be reduced. Alternatively, for example, the user can move his hand to the left to indicate that the left eye visual parameter needs to be adjusted, and with reference to FIG. 17, to indicate that the left eye visual parameter needs to be increased. Hands turn up. The user can move his hand to the right to indicate that the right eye visual parameter needs to be adjusted, and with reference to Figure 18, the hand is down to indicate that the right eye visual parameter needs to be reduced. Turn to. Alternatively, for example, the user may trigger the first instructional information by using both voice and posture. For example, the user can use voice to instruct the left eye visual parameters to be adjusted to turn the head up and to increase the left eye visual parameters based on preset steps.

The microprocessor 37 determines the adjusted visual parameters based on the visual parameter adjustment values indicated by the first instructional information, the adjusted visual parameters, Equation 1, and the actual screen-to-eye distance. The screen-to-eye distance adjustment value may be determined based on the value.

Alternatively, the memory 36 may further store a second comparison table similar to that in Table 1, and the second comparison table describes the correspondence between the visual parameter adjustment value and the screen-to-eye distance adjustment value. Used to indicate. By searching Table 2, the microprocessor 37 may determine the screen-to-eye distance adjustment value corresponding to the visual parameter adjustment value based on the visual parameter adjustment value indicated by the first instruction information. .. For example, myopia is used as an example. For details of the second comparison table, refer to Table 2 below. The visual parameter adjustment values in Table 2 are relatively small.

The myopia parameter adjustment value in Table 2 may be positive or negative. For example, the myopia parameter adjustment value becomes positive when it increases and becomes negative when it decreases. Correspondingly, the adjustment value may also be positive or negative. For example, when the myopia parameter adjustment value is positive, it indicates that the myopia parameter is increasing. In this case, the screen-to-eye distance adjustment value can be negative, indicating that the screen-to-eye distance needs to be reduced and the display screen needs to be moved in a direction closer to the human eye. When the myopia parameter adjustment value is negative, it indicates that the myopia parameter is decreasing. In this case, the screen-to-eye distance adjustment value can be positive, indicating that the screen-to-eye distance needs to be increased and the display screen needs to be moved away from the human eye.

Note that Table 2 above has been described by using myopia as an example, and hyperopia is similar to myopia. Details are not described again herein.

The screen-to-eye distance adjustment value may be the same as the above-mentioned adjustment target distance, and the first rotation direction and the first rotation circumference amount are determined based on the screen-to-eye distance adjustment value. The method is the same as the method for determining the first rotation direction and the first rotation circumference amount based on the adjustment target distance. The microprocessor 37 determines the fourth rotation direction and the fourth rotation circumference amount based on the adjustment value of the first screen-eye distance, and is based on the adjustment value of the second screen-eye distance. The fifth rotation direction and the fifth rotation circumference amount can be determined, and the position of the first display screen 312 and the position of the second display screen 322 can be finely adjusted. The specific process is not described again herein.

In another possible embodiment, the instruction input unit 38 is further configured to detect a second instruction information of the user when the attachment detection unit 310 detects that the terminal 30 has already been attached by the user. obtain. The second instructional information is used to instruct the first screen-inter-eye distance and / or the second screen-inter-eye distance to increase or decrease, or the second instructional information is the first display. Used to instruct the position of screen 312 and / or the position of the second display screen 322 to be adjusted back and forth. In other words, the second instruction information is used to directly indicate the position of the display screen.

The second instruction information may be specifically voice information and / or posture information. For example, the second instruction information can be used to increase the distance between the first screen and the eyes by 2 mm or to move the position of the first display screen 312 by 2 mm by using voice. In another example, the user turns his head to the right to indicate that he wants to adjust the second display screen 322 based on a preset step, increasing the second screen-eye distance, Alternatively, the head can be turned up to indicate that the position of the second display screen 322 is adjusted backwards (eg, 0.5 mm). In another example, the user turns his head to the right to indicate that he wants to adjust the second display screen 322 and moves his hand forward to indicate that the second screen-eye distance is reduced. , Or a second screen-you can move your hand backwards to indicate that you are increasing the distance between the eyes.

The microprocessor 37 determines the sixth rotation direction and the sixth rotation circumference of the first motor 331 based on the second instruction information, and / or the second instruction information. It may be further configured to determine the seventh rotation direction and the seventh rotation circumference of the motor 334. The first adjusting member 33 adjusts the position of the first display screen 312 based on the sixth rotation direction of the first motor 331 and the sixth rotation circumference amount, and / or the second motor 334. It may be further configured to adjust the position of the second display screen 322 based on the seventh rotation direction and the seventh rotation circumference.

In other words, the microprocessor 37 determines the sixth rotation direction and the sixth rotation circumference amount based on the adjustment value indicated by the second instruction information, which is the first screen-to-eye distance, and the second rotation direction is determined. By using the motor 331 of 1, the position of the first display screen 312 can be further fine-tuned. Alternatively, the microprocessor 37 determines the seventh rotation direction and the seventh rotation circumference based on the adjustment value indicated by the second instruction information, which is the second screen-to-eye distance, and the second. The position of the second display screen 322 can be further fine-tuned by using the motor 334 of.

After the user wears the head-mounted display 300, if the image on the display screen is not particularly clear, the user further inputs the first instruction information by voice or posture mode by using the instruction input unit 38, and visually. It is possible to understand that the parameters may be fine-tuned and the position of the display screen may be fine-tuned.

Therefore, prior to being worn by the user, the head-mounted display 300 provided in this embodiment of the present application adjusts the position of the display screen based on accurate visual information input by the user or stored in the memory 36. can do.

There is no need to make manual adjustments when the user's vision is restricted after wearing the 300. Therefore, visual restriction has no effect and the adjustment mode is more convenient, thereby improving the user experience.

In the prior art, there is another mode of directly adjusting the focal length by using voice. In this mode, a clearer image can be formed simply by repeatedly adjusting the position of the lens. As a result, the adjustment process is relatively long and the adjustment speed is relatively slow. The head-mounted display 300 provided in this embodiment of the present application can first make a rough adjustment of the position of the display screen based on the exact visual parameters input by the user, whereby the display screen is relatively large. It reaches the correct position and a relatively clear image is formed on the display screen. Then, the head-mounted display 300 can fine-tune the position of the display screen based on the instruction information triggered by the user by voice or posture, thereby forming a clear image into the adjusted display screen. , The adjustment process is simple and quick, which further enhances the user experience.

Further, the head-mounted display 300 may further fine-tune the eyepiece spacing in the same manner as the fine-tuning of the position of the display screen.

The instruction input unit 38 may be further configured to detect a third instruction information of the user when the attachment detection unit 310 detects that the terminal 30 has already been attached by the user. The third instructional information is used to instruct to increase or decrease the interpupillary distance parameter or eyepiece spacing. The microprocessor 37 may be further configured to determine the eighth rotation direction and the eighth rotation circumference of the third motor 343 based on the third instruction information. The second adjusting member 34 is configured to adjust the eyepiece spacing based on the eighth rotation direction of the third motor 343 and the eighth rotation circumference amount. The third instruction information may be specifically voice information and / or posture information. For example, with reference to FIG. 19, the user can indicate that the eyepiece spacing needs to be reduced by using a pinch gesture. For example, the user may instruct "two eyepieces closer to each other" by using voice.

The interpupillary distance parameter or eyepiece distance that increases or decreases based on the third instruction information may be the same as the above-mentioned adjustment target distance. The microprocessor 37 adjusts for details of the process in which the microprocessor 37 is configured to determine the eighth rotation direction and the eighth rotation circumference of the third motor 343 based on the third instruction information. See the above process of determining the first rotation direction and the first rotation circumference of the first motor 331 based on the target distance. Details are not described again herein.

After being worn by the user, the head-mounted display 300 can fine-tune the eyepiece spacing based on user-triggered instructional information in a non-manual manner such as voice or posture, thereby adjusting. Improves the user's visual experience by better matching the actual interpupillary distance of the user with different eyepiece spacing and feeling more comfortable after the user wears the head-mounted display 300.

Further, after fine-tuning the position of the display screen / eyepiece spacing, the head-mounted display 300 may further trigger the prompt information. Details are not described again herein.

Specifically, the instruction input unit 38 and the visual input unit 35 in this embodiment of the present application may be the same or different.

The current value of and the current value of the adjusted eyepiece spacing can be displayed.

In this embodiment of the present application, the visual parameter stored in the memory 36 may be a visual parameter obtained after the head-mounted display 300 makes adjustments based on the first instruction information, and may be stored in the memory 36. It should be noted that the interpupillary distance value made may be the interpupillary distance value obtained after the adjustment is made based on the third instruction information. In this way, when the head-mounted display 300 adjusts the position of the display screen or the eyepiece spacing based on the visual information stored in the memory, the adjustment is adjusted the last time the user used the head-mounted display 300. It can be done more accurately and more effectively based on the visual information.

For example, the visual parameters stored in the memory 36 may be specifically the visual parameters adjusted by using the voice or the posture when the user last used the head-mounted display 300. For example, if the left eye myopia parameter entered by the user by using the visual input unit 35 is 100 diopters, then using the instruction input unit 38 to instruct the memory 36 to increase the left eye myopia parameter by 3 diopters. The stored user's left eye visual parameter is 103 diopter myopia. In this way, the next time the user uses the head-mounted display 300, the user responds to the user's identification information and directly determines the position of the display screen and the eyepiece spacing based on the visual parameters stored in the memory 36. It can be adjusted accurately and effectively without the need to re-enter visual parameters.

Alternatively, in this embodiment of the present application, the visual parameter stored in the memory 36 may be a visual parameter input by the user and detected by the visual input unit 35, and the screen-eye stored in the memory 36. The interpupillary distance value may be a screen-to-eye distance value obtained before fine adjustment, and the interpupillary distance value stored in the memory 36 is input by the user and detected by the visual input unit 35. It may be an interpupillary parameter.

Further, in this embodiment of the present application, in a possible case, after the user has finished using the head-mounted display 300 this time, the head-mounted display 300 has a preset value for the position of the display screen and the eyepiece spacing. Can be returned to. In this case, when the user uses the head-mounted display 300 again, the head-mounted display 300 may adjust the position of the display screen and the eyepiece spacing based on the adjustment information corresponding to the user's identification information.

In another possible case, after the user has now finished using the head-mounted display 300, the head-mounted display 300 can store the display screen position and eyepiece spacing obtained after the current adjustment. In this case, if another user has not used the head-mounted display 300 before the user uses the head-mounted display 300 again, the position of the display screen and the eyepiece spacing on the head-mounted display 300 are the user's previous head-mounted. It remains the adjusted value when using the display 300. When the user uses the head-mounted display 300 again, a clear image can be directly observed without having to adjust the position of the display screen and the eyepiece spacing. If another user uses the head-mounted display 300 before the user uses the head-mounted display 300 again, the position of the display screen and the eyepiece spacing on the head-mounted display 300 may change. When the user uses the head-mounted display 300 again, the position of the display screen and the eyepiece spacing correspond to the user's identification information and can be adjusted accurately and effectively based on the visual information stored in the memory 36.

The position of the screen can be adjusted separately based on the accurate visual information entered by the user or based on the stored visual information corresponding to the user to form a clear image and the user's field of view can be expanded. It is not affected as in the prior art, thereby improving the user experience. Also, according to the method provided in this embodiment of the present application, the position of the display screen may be adjusted by rotating the motor, and the user does not need to manually adjust the position of the display screen. .. Therefore, the adjustment mode is simpler.

Further, the visual information may further include an interpupillary distance parameter, the interpupillary distance parameter is a reference value for the eyepiece spacing, and the eyepiece spacing is between the first eyepiece and the second eyepiece. The distance of. The first eyepiece includes the first display screen and the second eyepiece includes the second display screen. With reference to Figure 22, the method may further include the following steps:

103. 103. The terminal adjusts the eyepiece spacing based on the interpupillary distance parameter so that the adjusted eyepiece spacing is equal to the interpupillary distance parameter.
