焦距：透镜光心到焦点的距离。Focal length: The distance from the optical center of the lens to the focus.
焦度：焦距的倒数。Power: The reciprocal of the focal length.
屈光：光线由一种介质进入另一种不同折射率的介质时，会发生前进方向的改变，在眼光学中即称为屈光。Refraction: When light enters another medium of different refractive index from one medium, a change in the direction of advancement occurs, which is called refraction in eye optics.
屈光度：表示屈光力大小的单位，以D表示，即指平行光线经过该屈光物质，以焦点在1m时该屈光物质的屈光力为1屈光度或1D。以透镜而言，是指透镜焦度的单位，例如当透镜的焦距为1m时，该透镜的屈折力为1D屈光度。Diopter: A unit indicating the magnitude of refractive power, expressed as D, which means that parallel rays pass through the refractive material, and the refractive power of the refractive substance is 1 diopter or 1D at a focus of 1 m. In the case of a lens, it refers to the unit of lens power. For example, when the focal length of the lens is 1 m, the refractive power of the lens is 1 D diopter.
视场角：以透镜为顶点，以被测目标的物像可通过透镜的最大范围的两条边缘构成的夹角，称为视场角。视场角的大小决定了视野范围，视场角越大，视野就越大，在视场角以外的目标物体不在视野范围内。Field of view: The angle at which the lens is the apex, and the object image of the object to be measured can pass through the two edges of the largest range of the lens, called the angle of view. The size of the field of view determines the field of view. The larger the field of view, the larger the field of view. The target object outside the field of view is not in the field of view.
虚像距：透镜后所成虚像距离人眼的距离。Virtual image distance: The distance between the virtual image formed by the lens and the human eye.

For example, referring to FIG. 4, at least one first sliding slot 313 is disposed on the inner wall of the first lens barrel 311. The first display screen 312 is connected to the first lens barrel 311 through the at least one first sliding slot 313. The 312 can slide within the first chute 313.
对于图4所示的结构，第一调整构件可以进行如下第一调整操作：当第一调整构件33中的第一电机331转动时，第一电机331驱动第一转筒333旋转，第一转筒333旋转带动第一转轴332旋入或旋出第一转筒333，第一转轴332旋入或旋出第一转筒333带动第一显示屏312沿着垂直于第一显示屏312的方向移动，即带动第一显示屏312沿着第一镜筒311的内壁移动，从而达到调整第一显示屏312的位置的目的。For the structure shown in FIG. 4, the first adjustment member may perform a first adjustment operation: when the first motor 331 in the first adjustment member 33 is rotated, the first motor 331 drives the first reel 333 to rotate, the first rotation The rotation of the cylinder 333 drives the first rotating shaft 332 to screw in or out of the first rotating cylinder 333. The first rotating shaft 332 is screwed in or out of the first rotating cylinder 333 to drive the first display screen 312 in a direction perpendicular to the first display screen 312. Moving, that is, driving the first display screen 312 to move along the inner wall of the first lens barrel 311, thereby achieving the purpose of adjusting the position of the first display screen 312.
对于图4所示的结构，第一调整构件还可以进行如下第二调整操作：当第一调整构件33中的第二电机334转动时，第二电机334驱动第二转筒336旋转，第二转筒336旋转带动第二转轴335旋入或旋出第二转筒336，第二转轴335旋入或旋出第二转筒336带动第二显示屏322沿着垂直于第二显示屏322的方向移动，即带动第二显示屏322沿着第二镜筒321的内壁移动，从而达到调整第一显示屏312的位置的目的。For the structure shown in FIG. 4, the first adjustment member may also perform a second adjustment operation: when the second motor 334 in the first adjustment member 33 rotates, the second motor 334 drives the second drum 336 to rotate, second The rotation of the rotating drum 336 drives the second rotating shaft 335 to screw in or out of the second rotating drum 336. The second rotating shaft 335 is screwed in or out of the second rotating cylinder 336 to drive the second display screen 322 along the second display screen 322.

可见，本申请实施例提供的头显300，可以分别调整第一显示屏312的位置和第二显示屏322的位置。对于有视力缺陷的用户来说，本申请实施例提供的头显300，可以通过分别调整左眼对应的第一显示屏312的位置和右眼对应的第二显示屏322的位置来清晰成像，而不会像现有技术那样对用户的视场范围产生影响，从而可以提高用户的使用体验。It can be seen that the head display 300 provided by the embodiment of the present application can adjust the position of the first display screen 312 and the position of the second display screen 322, respectively. For a user with vision defects, the head display 300 provided by the embodiment of the present application can clearly image by separately adjusting the position of the first display screen 312 corresponding to the left eye and the position of the second display screen 322 corresponding to the right eye. It does not affect the user's field of view as in the prior art, thereby improving the user experience.
并且，由于用户的左眼、右眼的视力可能不完全一样，例如有的用户左眼视力有缺陷，但右眼视力正常，若同步调节第一显示屏312和第二显示屏322的位置，则往往只能使得一只眼睛能够观察到清晰的图像，而另一只眼睛不能观察到清晰的图像，总体视觉体验不佳。本申请实施例提供的头显300，可以根据实际视力情况分别调节左眼对应的第一显示屏312的位置和右眼对应的第二显示屏322的位置，从而使得左眼和右眼都能观察到清晰的图像，提高用户视觉体验。Moreover, since the visual acuity of the left eye and the right eye of the user may not be exactly the same, for example, the left eyesight of the user is defective, but the right eye vision is normal, and if the positions of the first display screen 312 and the second display screen 322 are synchronously adjusted, Often, only one eye can observe a clear image, while the other eye can not observe a clear image, the overall visual experience is not good. The head display 300 provided by the embodiment of the present application can adjust the position of the first display screen 312 corresponding to the left eye and the position of the second display screen 322 corresponding to the right eye according to the actual vision condition, so that both the left eye and the right eye can be Observe clear images and enhance the user's visual experience.
此外，现有技术中采用手动调节方式，而用户在佩戴头显300后视力受阻(参见图1)，不便于进行手动操作。本申请实施例提供的头显300，可以通过控制电机转动调整显示屏的位置，而不需要用户手动调整显示屏的位置，因而调节方式更为方便。In addition, the manual adjustment method is adopted in the prior art, and the user is obstructed after wearing the head display 300 (see FIG. 1), which is inconvenient for manual operation. The head display 300 provided by the embodiment of the present application can adjust the position of the display screen by controlling the rotation of the motor, without requiring the user to manually adjust the position of the display screen, and thus the adjustment mode is more convenient.
进一步地，参见图5a，本申请实施例提供的头显300还可以包括第二调整构件34。第二调整构件34可以包括第三电机343、传动组件344和螺杆组件345， 螺杆组件345与第一镜筒311和第二镜筒321通过螺纹连接。第二调整构件34可以执行以下第三调整操作：第三电机343通过传动组件344驱动螺杆组件345旋转，以使得第一镜筒311和第二镜筒321相互靠近或者相互远离，即使得两个镜筒同时向内或同时向外移动。Further, referring to FIG. 5a, the head display 300 provided by the embodiment of the present application may further include a second adjusting member 34. The second adjustment member 34 can include a third motor 343, a transmission assembly 344, and a screw assembly 345, The screw assembly 345 is screwed to the first barrel 311 and the second barrel 321 . The second adjustment member 34 can perform the following third adjustment operation: the third motor 343 drives the screw assembly 345 to rotate by the transmission assembly 344 such that the first barrel 311 and the second barrel 321 are close to each other or away from each other, that is, two The lens barrel moves inward or simultaneously at the same time.
也就是说，头显300可以通过第二调整构件34调整第一镜筒311和第二镜筒321的位置，使得第一镜筒311和第二镜筒321相互靠近或者相互远离，从而使得目镜间距增大或减小。That is, the head display 300 can adjust the positions of the first barrel 311 and the second barrel 321 by the second adjustment member 34 such that the first barrel 311 and the second barrel 321 are close to each other or away from each other, thereby making the eyepiece The spacing increases or decreases.
由于目镜间距应与用户瞳距保持一致，而不同用户的瞳距大小不同，因而目镜间距也不同。本申请实施例提供的头显300，可以通过电机转动来调节目镜间距，从而与不同用户的实际瞳距大小相适应，提高用户的视觉体验。并且，由于不需要手动调节，因而该调节方式更为方便。Since the eyepiece spacing should be consistent with the user's interpupillary distance, and the different user's interpupillary distances are different, the eyepiece spacing is also different. The head display 300 provided by the embodiment of the present application can adjust the eyepiece spacing by rotating the motor, thereby adapting to the actual user's actual distance, thereby improving the user's visual experience. Moreover, this adjustment method is more convenient because manual adjustment is not required.

Among them, the far-sighted user corresponds to a larger screen distance, and the corresponding screen distance is also larger; the near-screen user corresponds to a smaller screen distance, and the corresponding screen distance reference value is also smaller.
需要说明的是，本申请实施例提供的头显300可以在用户佩戴之前，根据视力信息执行上述第一调整操作、第二调整操作和第三调整操作。此时，用于用户尚未佩戴头显，因而并不能获知人眼的实际位置，屏眼距指的是显示屏与预设的人眼参考位置之间的距离。其中，人眼参考位置通常设置在距离透镜10mm-20mm之间。示例性的，左眼参考位置可以设置于距离第一透镜314的位置15mm的地方，右眼位置可以设置于距离第二透镜324位置15mm的地方。It should be noted that the head display 300 provided by the embodiment of the present application may perform the first adjustment operation, the second adjustment operation, and the third adjustment operation according to the vision information before the user wears. At this time, the user has not worn the head display, and thus the actual position of the human eye is not known, and the screen distance refers to the distance between the display screen and the preset human eye reference position. Among them, the human eye reference position is usually set between 10mm and 20mm from the lens. Illustratively, the left eye reference position may be placed 15 mm from the position of the first lens 314, and the right eye position may be placed 15 mm from the second lens 324 position.
在一种实施方式中，微处理器37用于根据左眼的视力参数确定第一屏眼距参考值可以包括：根据左眼的视力参数和表达式一确定第一屏眼距参考值。微处理器37用于根据右眼的视力参数确定第二屏眼距参考值可以包括：根据右眼的视力参数和表达式一确定第二屏眼距参考值。其中，表达式一可以表示为：In an embodiment, the determining, by the microprocessor 37, the first screen distance reference value according to the vision parameter of the left eye may include determining the first screen distance reference value according to the vision parameter of the left eye and the expression 1. The determining, by the microprocessor 37, the second screen distance reference value according to the vision parameter of the right eye may include determining the second screen distance reference value according to the right eye's vision parameter and the expression 1. Among them, the expression one can be expressed as:
ui＝1/(Di-1/k)u i =1/(D i -1/k)
在表达式一中，当ui表示第一屏眼距参考值时，Di表示左眼的焦度；当ui表示第二屏眼距参考值时，Di表示右眼的焦度。k表示常数，具体可以与实际产品的特性有关，例如透镜参数、产品规格尺寸等。焦度Di的单位为1/米，1/米又叫屈光度，用D表示，且1屈光度对应100度视力。具体的，近视100度对应-1dD，远视100度对应+1D。这样，在根据表达式一计算的屏眼距参考值中，近视参数对应的屏眼距参考值小，远视参数对应的屏眼距参考值大。In Expression 1, when u i represents the first screen distance reference value, D i represents the power of the left eye; when u i represents the second screen distance reference value, D i represents the power of the right eye. k represents a constant, which may be related to the characteristics of the actual product, such as lens parameters, product size, and the like. The unit of power D i is 1/m, 1/m is also called diopter, which is represented by D, and 1 diopter corresponds to 100 degrees of vision. Specifically, myopia 100 degrees corresponds to -1 dD, and far vision 100 degrees corresponds to +1 D. Thus, in the screen distance reference value calculated according to the expression one, the screen distance corresponding to the near vision parameter is smaller than the reference value, and the distance corresponding to the far vision parameter is larger than the reference value.
具体的，在一种情况下，微处理器37可以根据每次用户输入的视力参数(左眼的视力参数/和或右眼的视力参数)以及表达式一，计算屏眼距参考值(第一屏眼距参考值和/或第二屏眼距参考值)。Specifically, in one case, the microprocessor 37 can calculate the screen distance reference value according to the visual parameter (the visual parameter of the left eye and/or the visual parameter of the right eye) and the expression 1 of the user input each time (the first) One screen eye distance reference value and / or second screen eye distance reference value).
或者，在另一种情况下，头显300还可以包括存储器36，存储器36中可以存储有预设的第一对照表，该第一对照表中包括视力参数和屏眼距的对应关系，且该第一对照表中屏眼距与视力参数的对应关系满足上述表达式一。示例性的，以视力参数为近视为例，本申请实施例提供的一种第一对照表具体可以为如下表1：Alternatively, in another case, the head display 300 may further include a memory 36. The memory 36 may store a preset first comparison table, where the first comparison table includes a correspondence relationship between the vision parameter and the screen distance, and The correspondence between the eye distance and the visual acuity parameter in the first comparison table satisfies the above expression 1. Illustratively, the first comparison table provided by the embodiment of the present application may be as follows:

100度100 degree 参考值2Reference value 2
150度150 degrees 参考值3Reference value 3
200度200 degrees 参考值4Reference value 4
250度250 degrees 参考值5Reference value 5
300度300 degrees 参考值6Reference value 6
...... ......
微处理器37在确定第一屏眼距参考值时，可以根据第一显示屏312当前的位置确定当前第一显示屏312和左眼参考位置的距离即当前第一屏眼距，从而根据第一屏眼距参考值与当前第一屏眼距的差值，确定第一电机331的第一转动方向和第一转动圈数。When determining the first screen distance reference value, the microprocessor 37 may determine the distance between the current first display screen 312 and the left eye reference position, that is, the current first screen distance according to the current position of the first display screen 312, thereby The difference between the one-eye distance reference value and the current first screen eye distance determines the first rotation direction and the first rotation number of the first motor 331.
需要说明的是，在每次使用头显300时，头显300中显示屏的当前位置可以是预设的位置，也可以是保留的上次调整后的位置，这里不做具体限定。It should be noted that, when the head display 300 is used, the current position of the display screen in the head display 300 may be a preset position, or may be a reserved last adjusted position, which is not specifically limited herein.
举例来说，以第一电机331为例，若微处理器37根据左眼的视力参数确定的第一屏眼距参考值为25mm，当前第一屏眼距为20mm，则还需要将第一显示屏312向后(向远离左眼参考位置的方向)调整5mm，可以记为待调整距离为+5mm。微处理器37可以根据该5mm以及第一转轴332的第一螺距计算第一电机331的第一转动圈数。其中，第一转动圈数具体可以为5mm与第一螺距的商。若微处理器37根据左眼的视力参数确定的第一屏眼距参考值为25mm，当前第一屏眼距为30mm，则还需要将第一显示屏312向前(向靠近左眼参考位置的方向)调整5mm，可以记为待调整距离为-5mm。并且，微处理器37可以根据需要向前还是向后调整第一显示屏312的位置，确定第一电机331的第一转动方向是顺时针转动还是逆时针转动。具体的，第一显示屏312的移动方向与第一电机331的转动方向的对应关系，与第一转筒333和第一转轴332的螺纹的螺旋方向有关。类似的，微处理器37还可以确定第二电机334的第二转动方向和第二转圈。For example, taking the first motor 331 as an example, if the first screen distance reference value determined by the microprocessor 37 according to the vision parameter of the left eye is 25 mm, and the current first screen distance is 20 mm, the first need to be the first The display screen 312 is adjusted backwards (in a direction away from the left eye reference position) by 5 mm, and can be recorded as a distance to be adjusted of +5 mm. The microprocessor 37 can calculate the first number of revolutions of the first motor 331 based on the 5 mm and the first pitch of the first rotating shaft 332. Wherein, the first number of rotations may specifically be a quotient of 5 mm and the first pitch. If the first screen distance reference value determined by the microprocessor 37 according to the vision parameter of the left eye is 25 mm, and the current first screen distance is 30 mm, the first display screen 312 needs to be forward (toward the left eye reference position). The direction of the adjustment is 5mm, which can be recorded as the distance to be adjusted is -5mm. Moreover, the microprocessor 37 can adjust the position of the first display screen 312 forward or backward as needed to determine whether the first rotational direction of the first motor 331 is clockwise or counterclockwise. Specifically, the corresponding relationship between the moving direction of the first display screen 312 and the rotating direction of the first motor 331 is related to the spiral direction of the threads of the first drum 333 and the first rotating shaft 332. Similarly, the microprocessor 37 can also determine the second direction of rotation of the second motor 334 and the second revolution.
此外，在一种可能的实施方式中，存储器36中还可以保存有预设的第二对照表，该第二对照表包括显示屏的待调整距离与电机的转动方向及转动圈数的对应关系。微处理器37在确定待调整距离后，可以通过查找第二对照表确定电机的转动方向和转动圈数。In addition, in a possible implementation, the memory 36 may further store a preset second comparison table, where the second comparison table includes a correspondence between the to-be-adjusted distance of the display screen and the rotation direction and the number of rotations of the motor. . After determining the distance to be adjusted, the microprocessor 37 can determine the rotation direction and the number of rotations of the motor by searching the second comparison table.
在微处理器37确定第一电机331的第一转动方向和第一转动圈数之后，第一调整构件33可以执行上述第一调整操作，以使得调整后的第一显示屏312的位置与左眼参考位置的距离等于第一屏眼距参考值。在微处理器37确定第二电机334的第二转动方向和第二转动圈数之后，第一调整构件33可以执行上述第二调整操作，以使得调整后的第二显示屏322的位置与左眼参考位置的距离等于第二屏眼距参考值。After the microprocessor 37 determines the first rotational direction of the first motor 331 and the first rotational number, the first adjustment member 33 may perform the above-described first adjustment operation such that the adjusted position of the first display screen 312 and the left The distance of the eye reference position is equal to the first screen distance reference value. After the microprocessor 37 determines the second rotational direction and the second rotational number of the second motor 334, the first adjustment member 33 may perform the second adjustment operation described above such that the adjusted position of the second display screen 322 is left. The distance of the eye reference position is equal to the second screen distance reference value.
在该种可能的实现方式中，头显可以根据用户输入的准确的视力参数，确定屏眼距参考值，从而确定电机的转动方向和转动圈数，进而调整显示屏的位置，使得有视力缺陷的用户能够在调整后的显示屏上观察到清晰的图像。In this possible implementation manner, the head display can determine the distance from the reference value according to the accurate vision parameter input by the user, thereby determining the rotation direction and the number of rotations of the motor, thereby adjusting the position of the display screen to make the vision defect The user can see a clear image on the adjusted display.
在第二种可能的实现方式中，头显300还可以包括存储器36，存储器36中存储的视力信息包括与用户的标识信息对应的左眼的视力参数和/或右眼的视力参数。在该种情况下，头显300可以根据存储器36保存的与该用户的标识信息对应的准确的视力参数，确定屏眼距参考值，从而确定电机的转动方向和转动圈数，进而调整显示屏的位置，使得有视力缺陷的用户能够在调整后的显示屏上观察到清晰的图像。In a second possible implementation, the head display 300 may further include a memory 36. The vision information stored in the memory 36 includes a vision parameter of the left eye corresponding to the identification information of the user and/or a vision parameter of the right eye. In this case, the head display 300 can determine the distance from the reference value according to the accurate vision parameter stored in the memory 36 corresponding to the identification information of the user, thereby determining the rotation direction and the number of rotations of the motor, thereby adjusting the display screen. The location allows visually impaired users to see clear images on the adjusted display.
在另外的实施例方式中，视力输入部件35检测的视力信息或存储器36中存储 的视力信息包括第一屏眼距的数值和第二屏眼距的数值。在该种可能的实现方式中，头显可以根据用户输入的准确的屏眼距数值，确定屏眼距的参考值，从而确定电机的转动方向和转动圈数，进而调整显示屏的位置，使得有视力缺陷的用户能够在调整后的显示屏上观察到清晰的图像。In another embodiment, the vision information detected by the vision input unit 35 or stored in the memory 36 is stored. The visual acuity information includes the value of the first screen eye distance and the value of the second screen eye distance. In this possible implementation manner, the head display can determine the reference value of the screen distance according to the accurate screen distance value input by the user, thereby determining the rotation direction and the number of rotations of the motor, thereby adjusting the position of the display screen, thereby making the position of the display screen Users with visual impairments can see clear images on the adjusted display.
尤其地，上述第一种可能的实现方式可以适用于用户首次使用头显300的场景。在该场景中，存储器36中未保存有与用户的标识信息对应的视力信息，此时用户需要通过视力输入部件35输入左眼的视力参数和/或右眼的视力参数。在该种情况下，若用户并未输入视力参数，则头显300默认用户视力正常，视力参数为预设的正常视力参数。其它种可能的实现方式可以适用于用户非首次使用头显300的场景。在该场景中，存储器36中可以保存有与用户的标识信息相对应的视力信息，以便于用户在下次使用头显300时，可以根据存储器36中的视力信息，更加高效地进行调节，而不需要用户再次输入视力信息。In particular, the first possible implementation described above may be applied to a scenario in which the user first uses the head display 300. In this scenario, the visual acuity information corresponding to the identification information of the user is not stored in the memory 36. At this time, the user needs to input the visual acuity parameter of the left eye and/or the visual acuity parameter of the right eye through the visual acuity input component 35. In this case, if the user does not input the visual acuity parameter, the head display 300 defaults to the normal visual acuity, and the visual acuity parameter is a preset normal visual acuity parameter. Other possible implementations may be applicable to scenarios where the user is not using the headset 300 for the first time. In this scenario, the memory 36 may store vision information corresponding to the user's identification information, so that the user can adjust the vision more efficiently according to the vision information in the memory 36 when the head display 300 is used next time. The user is required to enter vision information again.

The second adjusting member 34 is configured to perform the third adjusting operation according to the third rotating direction of the third motor 343 and the third rotating ring, so that the distance between the adjusted first eyepiece and the second eyepiece is equal to 瞳Distance parameter.
微处理器37确定第三电机343的第三转动方向和第三转动圈数的方法，与微处理器37确定第一电机331的第一转动方向和第一转动圈数类似，这里不再赘述。其中，瞳距参数与当前目镜间距之间的差值可以类似于上述待调整距离。The microprocessor 37 determines the third rotation direction and the third rotation number of the third motor 343, and the microprocessor 37 determines that the first rotation direction of the first motor 331 is similar to the first rotation rotation number, and details are not described herein. . Wherein, the difference between the pitch parameter and the current eyepiece distance may be similar to the above-mentioned distance to be adjusted.

Alternatively, for example, the memory 36 may also store a preset adjustment step size, for example, the visual acuity parameter is 1 degree, and the user may voice up to increase the left eye myopia degree, that is, equivalent to indicating that the left eye myopia degree is increased by 1 degree. Or, by way of example, the user can turn the head to the left to indicate that the eyesight parameter of the left eye needs to be adjusted, and turn the head up to indicate that the user's vision parameter is raised; the user can turn the head to the right to Indicates that the vision parameter of the right eye needs to be adjusted, and the head is turned down to indicate that the user's vision parameter is lowered.

The microprocessor 37 can determine the adjustment value of the screen distance corresponding to the adjustment value of the vision parameter by using the lookup table 2 according to the adjustment value of the vision parameter indicated by the first indication information. For example, the second comparison table can be specifically referred to the following Table 2. The values of the adjustment values of the visual acuity parameters in Table 2 are small.
表2Table 2
近视参数调整值Myopia parameter adjustment value 屏眼距调整值Screen distance adjustment value
...... ......
-1.5度-1.5 degrees 调整值1Adjustment value 1
-1度-1 degree 调整值2Adjustment value 2
-0.5度-0.5 degrees 调整值3Adjustment value 3
0.5度0.5 degrees 调整值4Adjustment value 4
1度1 degree 调整值5Adjustment value 5
1.5度1.5 degrees 调整值6Adjustment value 6
...... ......
其中，表2中近视参数的调整值可以有正、负之分，例如增大时为正，减小时为负。相应的，调整值也可以有正、负之分。例如，当近视参数调整值为正时，表示近视参数增大，此时屏眼距调整值可以为负，表示屏眼距需要减小，显示屏需要向靠近人眼的方向移动；当近视参数调整值为负时，表示近视参数调小，此时屏眼距调整值可以为正，表示屏眼距需要增大，显示屏需要向远离人眼的方向移动。Among them, the adjustment value of the nearsighted parameter in Table 2 may have positive and negative points, for example, positive when increasing, and negative when decreasing. Correspondingly, the adjustment value can also have positive and negative points. For example, when the adjustment value of the nearsighted parameter is positive, it indicates that the nearsighted parameter is increased, and the adjustment value of the eye shadow distance may be negative, indicating that the distance of the screen eye needs to be reduced, and the display screen needs to move toward the human eye; when the near vision parameter When the adjustment value is negative, it means that the myopia parameter is reduced. At this time, the adjustment value of the screen eye distance can be positive, indicating that the screen distance needs to be increased, and the display screen needs to move away from the human eye.
值得注意的是，以上表2是以近视为例进行说明的，对于远视情况与近视类似，这里不再赘述。It is worth noting that Table 2 above is illustrated by a similar example. For hyperopia, it is similar to myopia, and will not be described here.

The first screen distance and/or the second screen distance are reduced or decreased, or the second indication information is used to indicate the position of the first display screen 312 and/or the second display screen 322 being adjusted forward or backward. That is, the second indication information is used to directly indicate the position of the display screen.
其中，第二指示信息具体可以为语音信息和/或体态信息。示例性的，第二指示信息可以通过语音调大第一屏眼距2mm，或者向远处移动第一显示屏312的位置2mm。再示例性，用户可以向右转动头部，表示调节第二显示屏322，向上转动头部表示调大第二屏眼距，或表示按照预设步长(例如0.5mm)向后调节第二显示屏322的位置。再示例性，用户可以向右转动头部，表示调节第二显示屏322，向前移动手部以表示调小第二屏眼距，或者向后移动手部以表示调大第二屏眼距。The second indication information may specifically be voice information and/or body information. Exemplarily, the second indication information may be adjusted by the voice to increase the first screen distance by 2 mm, or to move the position of the first display screen 312 to the distance by 2 mm. By way of example, the user can turn the head to the right to indicate that the second display screen 322 is adjusted, the upward rotation of the head indicates that the second screen distance is turned up, or that the adjustment is performed backward according to the preset step size (for example, 0.5 mm).

也就是说，微处理器37可以根据第二指示信息指示的第一屏眼距的调整值，确定第六转动方向和第六转动圈数，进而通过第一电机331微调第一显示屏312的位置；或者，微处理器37可以根据第二指示信息指示的第二屏眼距的调整值，确定第七转动方向和第七转动圈数，进而通过第二电机334微调第二显示屏322的位置。That is, the microprocessor 37 can determine the sixth rotation direction and the sixth rotation number according to the adjustment value of the first screen distance indicated by the second indication information, and further fine-tune the first display screen 312 by the first motor 331.

与现有技术中手动调节焦距的方式相比，本申请实施例提供的头显300不仅不会影响用户的视场范围，而且不需要用户在佩戴之后视力受阻的情况下进行手动调节，因而不会受到视力受阻的影响，调节方式更为方便，因此更能提高用户的使用体验。Compared with the method of manually adjusting the focal length in the prior art, the head display 300 provided by the embodiment of the present application not only does not affect the field of view of the user, but also does not require the user to perform manual adjustment when the vision is blocked after wearing, and thus does not It will be affected by the obstruction of vision and the adjustment method is more convenient, so it can improve the user experience.
现有技术中还存在一种直接通过语音调节焦距的方式，该种方式需要反复调节透镜的位置才能使得成像较为清晰，调节过程较长，调节速度较慢。本申请实施例提供的头显300可以首先根据用户输入的准确的视力参数，对显示屏的位置进行粗调，以使得显示屏到达一个较为准确的位置，使得显示屏成像较为清晰；而后可以根据用户通过语音、体态等方式触发的指示信息对显示屏的位置进行微调，从而可以使得调整后的显示屏的成像更为清晰，且调节过程简单快速，更能提高用户使用体验。In the prior art, there is also a way to adjust the focal length directly by voice. This method requires repeated adjustment of the position of the lens to make the imaging clear, the adjustment process is long, and the adjustment speed is slow.

进一步地，与微调显示屏的位置类似，头显300还可以微调目镜间距。Further, similar to the position of the fine-tuning display, the head display 300 can also fine-tune the eyepiece spacing.
具体的，指示输入部件38还可以用于，在佩戴检测部件310检测到终端30已被用户佩戴时，检测用户的第三指示信息，第三指示信息用于指示增大或减小瞳距参数或目镜间距。微处理器37还可以用于，根据第三指示信息确定第三电机343的第八转动方向和第八转动圈数。第二调整构件34还用于，根据第三电机343的第八转动方向和第八转动圈数，调整目镜间距。其中，第三指示信息具体可以为语音和/或体态信息。示例性的，参见图19，用户可以通过捏合手势表示需要减小目镜间距。示例性的，用户可以通过语音指示“靠近两个目镜”。Specifically, the indication input component 38 is further configured to detect third indication information of the user when the wearing detection component 310 detects that the terminal 30 has been worn by the user, and the third indication information is used to indicate increasing or decreasing the distance parameter. Or eyepiece spacing.

其中，第三指示信息指示的增大或减小的瞳距参数或目镜间距可以类似于上述待调整距离，关于微处理器37用于根据第三指示信息确定第三电机343的第八转动方向和第八转动圈数的过程，具体可以参见上述微处理器37根据待调整距离确定第一电机331的第一转动方向和第一转动圈数的过程，这里不再赘述。Wherein, the increased or decreased pitch parameter or the eyepiece pitch indicated by the third indication information may be similar to the above-mentioned to-be-adjusted distance, and the microprocessor 37 is configured to determine the eighth rotation direction of the third motor 343 according to the third indication information. For the process of determining the first rotation direction and the first rotation number of the first motor 331 according to the distance to be adjusted, the process of determining the first rotation direction of the first motor 331 by the microprocessor 37 is not described herein.
这样，本申请实施例提供的头显300可以在用户佩戴之前，根据用户输入的准确的瞳距参数调整目镜间距；而在用户佩戴之后，可以根据用户通过语音、体态等非手动操作方式触发的指示信息对目镜间距进行微调，从而使得调整后的目镜间距与不同用户的实际瞳距更好地匹配，使得用户佩戴后的感觉更为舒适，提高用户的视觉体验。In this way, the head display 300 provided by the embodiment of the present application can adjust the eyepiece spacing according to the accurate distance parameter input by the user before being worn by the user; and after the user wears, the user can trigger according to the non-manual operation mode such as voice and body posture.

另外，头显300在微调显示屏的位置/目镜间距之后，还可以触发提示信息，这里不再赘述。In addition, the head display 300 can also trigger the prompt information after fine-tuning the position of the display screen/eyepiece spacing, which will not be described here.
具体的，本申请实施例中的指示输入部件38与视力输入部件35可以是同一部件，也可以不同。Specifically, the instruction input component 38 and the vision input component 35 in the embodiment of the present application may be the same component or different.
此外，用户在使用头显300时，用户在观察到清晰的图像后，还可以触发头显300通过显示屏显示当前调整后的屏眼距的数值以及目镜间距的数值。 In addition, when the user uses the head display 300, after viewing the clear image, the user can also trigger the head display 300 to display the value of the currently adjusted screen eye distance and the value of the eyepiece spacing through the display screen.
值得注意的是，在本申请实施例中，存储器36中存储的视力参数可以是头显300根据第一指示信息调整后的视力参数；存储器36中存储的瞳距的数值，可以是根据上述第三指示信息调整后的瞳距的数值。这样，在头显300根据存储器中存储的视力信息调整显示屏的位置或目镜间距时，可以根据上次使用时调整后的视力信息，更加准确、高效地进行调整。It should be noted that, in the embodiment of the present application, the visual acuity parameter stored in the memory 36 may be the visual acuity parameter adjusted by the head display 300 according to the first indication information; the value of the interpupillary distance stored in the memory 36 may be according to the above The value of the third distance after the adjustment of the information. Thus, when the head display 300 adjusts the position of the display screen or the eyepiece pitch based on the visual acuity information stored in the memory, it is possible to perform the adjustment more accurately and efficiently based on the adjusted vision information at the time of the last use.
例如，存储器36中存储的视力参数具体可以为用户上次使用时，通过语音或体态指示调整后的视力参数。举例来说，若用户通过视力输入部件35输入的左眼的近视参数为100度，而后又通过指示输入部件38指示调大左眼近视参数3度，则存储器36中保存的用户的左眼的视力参数为近视103度。这样，用户在下次使用时，可以根据存储器36中保存的与该用户的标识信息对应的视力参数，直接、准确、高效地调整显示屏的位置和目镜间距，而不需要用户再次输入视力参数。For example, the visual acuity parameter stored in the memory 36 may specifically be an adjusted visual acuity parameter indicated by a voice or a body state when the user last used. For example, if the myopia parameter of the left eye input by the user through the vision input unit 35 is 100 degrees, and then the instruction of the input unit 38 is directed to increase the left eye myopia parameter by 3 degrees, the left eye of the user saved in the memory 36 The visual acuity parameter is 103 degrees of myopia. In this way, the user can adjust the position of the display screen and the eyepiece distance directly, accurately, and efficiently according to the vision parameter corresponding to the identification information of the user stored in the memory 36, without using the user to input the vision parameter again.
或者，在本申请实施例中，存储器36中存储的视力参数也可以视力输入部件35检测到的用户输入的视力参数；存储器36中存储的屏眼距的数值也可以是微调前的屏眼距的数值；存储器36中存储的瞳距的数值，也可以是视力输入部件35检测到的用户输入的瞳距参数。Alternatively, in the embodiment of the present application, the visual acuity parameter stored in the memory 36 may also be the visual acuity parameter input by the visual input component 35; the value of the inter-screen distance stored in the memory 36 may also be the pre-fine-screen distance of the eye. The value of the interpupillary distance stored in the memory 36 may also be the interpupillary parameter of the user input detected by the visual acuity input unit 35.
此外，在本申请实施例中，在一种可能的情况下，在用户本次使用结束后，头显300可以将显示屏位置和目镜间距恢复为预设值。该种情况下，当该用户再次使用时，头显300可以根据该用户的标识信息对应的调整信息，调整显示屏的位置和目镜间距。In addition, in the embodiment of the present application, in a possible case, after the user ends this use, the head display 300 can restore the display screen position and the eyepiece spacing to a preset value. In this case, when the user uses the user again, the head display 300 can adjust the position of the display screen and the eyepiece spacing according to the adjustment information corresponding to the identification information of the user.
在另一种可能的情况下，在用户本次使用结束后，头显300可以保留本次调整后的显示屏的位置和目镜间距。该种情况下，若该用户再次使用之前其他用户没有使用过该头显300，则该头显300中的显示屏的位置和目镜间距仍为该用户上次使用时调整后的数值，该用户再次使用时，不需要再对显示屏的位置和目镜间距进行调节，可以直接观察到清楚的图像。若在该用户再次使用之前，其他用户使用过该头显300，则头显300中的显示屏的位置和目镜间距可能发生了改变，则该用户再次使用时，可以根据存储器36中保存的与该用户的标识信息对应的视力信息，准确、高效地调整显示屏的位置和目镜间距。In another possible case, after the user has finished using this time, the head display 300 can retain the position of the adjusted display screen and the eyepiece spacing.
