DETAILED DESCRIPTION

[0048] The embodiments of the present invention solve the technical problem of how to improve the adjustment efficiency of a head-mounted display device by providing a head-mounted display device control method, device and head-mounted display device.

[0049] In order to better understand the technical solution of the present invention, the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0050] like Figure 1-4As shown, the head-mounted display device of an embodiment of the present invention includes a shell 60 and a wearing component 70; the shell 60 includes a front cover 601 and a rear cover 602 fixedly connected to the front cover 601, and the rear cover 602 is provided with two through holes 6021 for human eye observation, and the through holes 6021 can be cylindrical; the wearing component 70 has a plurality of headbands 701, one ends of the plurality of headbands 701 are respectively fixed to a plurality of end surfaces of the rear cover 602, and the other ends of the plurality of headbands 701 are fixed together, such as three headbands 701 can be respectively fixed to the upper end surface, the left end surface, and the right end surface of the rear cover 602.

[0051] In this embodiment, a bracket 21 and two lens barrels 11 are provided in the housing 60; a sliding rod 211 is provided on the bracket 21 and a screen 22 is fixed thereto; the bracket 21 may be frame-shaped, so that the screen 22 may be fixed in the bracket 21, and the screen 22 may be fixed in the bracket 21 by adhesive; the lens barrels 11 correspond to the through holes 6021 one by one, the lens barrels 11 may be cylindrical, a lens 12 is fixed in each lens barrel 11, the lens 12 may be fixed in the lens barrel 11 by glue, the lens 12 is located between the screen 22 and the corresponding through hole 6021, and a sliding groove is provided on the lens barrel 11 111; the slide bar 211 is located in the slide groove 111, the four corners of the bracket 21 can be respectively provided with a slide bar 211, the four corners of the lens barrel 11 can be respectively provided with a slide groove 111, and each slide bar 211 is respectively located in the corresponding slide groove 111; the lens 12 is composed of a first lens 121 and a second lens 122, and a composite film 13 is attached to the lens 12, which can be the first lens 121 with the composite film 13, the second lens 122 with the composite film 13, or both the first lens 121 and the second lens 122 with the composite film 13.

[0052] In this embodiment, a motor 31, an iris assembly 41, a sensor and a controller 51 are also provided in the housing 60. The controller 51 is electrically connected to the motor 31, the iris assembly 41 and the sensor respectively; the motor 31 can be fixed on the lens barrel 11 or on the bracket 21; the iris assembly 41 can be fixed at a position where the human eye can be detected.

[0053] Among them, the lens 12 is a convex lens, which is used to image the image displayed on the screen 22 on the retina of the human eye; the motor 31 is used to drive the slide bar 211 to slide in the slide groove 111; the iris assembly 41 is used to collect the user's iris information; the sensor is used to detect the position information of the screen 22; the composite film 13 can change the optical path and reduce the thickness requirement of the lens 12 for imaging, which is conducive to the miniaturization of the head-mounted display device.

[0054] Among them, the composite film 13 is a multi-film layer structure, and the composite film 13 includes a first anti-reflective film layer, an ink layer, a second anti-reflective film layer and an infrared filter film layer. The ink layer is a ring-shaped structure layer, and the ink layer is arranged at the edge of the composite film 13, and the ink layer is arranged between the first anti-reflective film layer and the second anti-reflective film layer to block the edge light. The first anti-reflective film layer and the second anti-reflective film layer are used to increase the transmittance of light. The infrared filter film layer is a thinner infrared filter film layer, which is used to filter excess light. It can be understood that in VR glasses, a filter is used or an infrared filter film technology is set, which can achieve better picture quality by filtering light of a specific color, and by filtering out unnecessary spectral components or interfering light in the incident light, reducing the interfering components in the background, and improving the contrast of the target to the background, thereby improving the signal-to-noise ratio of the system and enhancing the user's visual experience and immersion.

[0055] When a user uses the head mounted display device, the user can put the multiple headbands 701 on the head and align the two eyes with the two through holes 6021 respectively, and can watch the picture displayed on the screen 22 through the through holes 6021 and the lens 12 in sequence. If the picture on the screen 22 seen by the user is not clear, the controller 51 can control the motor 31 to drive the slide bar 211 to slide in the slide groove 111, drive the bracket 21 to slide on the lens barrel 11, thereby changing the position of the screen 22, that is, changing the distance between the screen 22 and the lens 12, and adjusting the clarity of the picture displayed on the screen 22 seen by the human eye.

[0056] like Figure 5 As shown, the present invention provides a head mounted display device control method that can be applied to the controller 51 mentioned above, including:

[0057] Step S1, obtaining the collected iris information of the user;

[0058] Step S2, determining the screen position information corresponding to the user's iris information according to the pre-stored one-to-one correspondence between the iris information and the screen position information, and recording it as the target position information;

[0059] Step S3, controlling the screen in the head mounted display device to move to a position corresponding to the target position information.

[0060] The iris information and the corresponding screen position information satisfy the condition that when the screen is at the position corresponding to the screen position information, the user corresponding to the iris information can clearly see the picture displayed on the screen.

[0061] That is, the controller is used to obtain the user's iris information collected by the iris component, and determine the screen position information corresponding to the user's iris information based on the one-to-one correspondence between the pre-stored iris information and the screen position information, and record it as the target position information, so as to move the screen to the position corresponding to the target position information.

[0062] When the user uses the head-mounted display device for the first time, before step S1, the head-mounted display device control method also includes: collecting and storing the user's iris information; after receiving a confirmation signal of the screen position, storing the current screen position information, and establishing a corresponding relationship between the stored screen position information and the iris information; wherein the confirmation signal indicates that the user can clearly see the picture displayed on the screen.

[0063] When a user uses the head-mounted display device for the first time, the iris component will collect and store the user's iris information; the user can determine whether he can see the picture displayed on the screen clearly. If the user determines that he can see the picture displayed on the screen clearly, the user can press the confirmation button on the shell to trigger a confirmation signal, which means that the user can now see the picture displayed on the screen clearly; if the user determines that he cannot see the picture displayed on the screen clearly, the user can adjust the adjustment button on the shell to trigger the adjustment signal. After receiving the adjustment signal, the controller controls the motor to drive the bracket to slide on the lens barrel to change the position of the screen. The user can repeatedly adjust the adjustment button until he can see the picture displayed on the screen clearly, and then press the confirmation button to trigger the confirmation signal; after receiving the confirmation signal, the controller will control the sensor to detect and store the current position information of the screen, and match the current position information of the screen with the user's iris information to complete the entry of the user's iris information.

[0064] When the user uses the head-mounted display device subsequently, the iris component will collect the user's iris information, and the controller will search for the screen position information corresponding to the stored iris information and control the sensor to detect the current position information of the screen. If the current position information of the screen is consistent with the target position information, it means that the current position of the screen can enable the user to see the picture displayed on the screen clearly, and there is no need to adjust the screen position.

[0065] If the current position information of the screen is inconsistent with the target position information, it means that the user cannot see the image displayed on the screen clearly at the current position of the screen and the screen position needs to be adjusted. The controller will automatically control the motor to drive the bracket to slide on the lens barrel, and control the sensor to detect the actual position information of the screen in real time until the actual position information of the screen is consistent with the target position information, and the adjustment of the screen position is completed. At this time, step S3 includes: obtaining the current position information of the screen; if the current position information is inconsistent with the target position information, controlling the screen to move to the position corresponding to the target position information.

[0066] From the above, it can be seen that the head-mounted display device control method of an embodiment of the present invention determines the screen target position information corresponding to the user's iris information based on the one-to-one correspondence between the pre-stored iris information and the screen position information, and controls the screen in the head-mounted display device to move to the position corresponding to the target position information. The user can then clearly see the picture displayed on the screen, thereby realizing automatic adjustment of the head-mounted display device and improving the adjustment efficiency.

[0068] An acquisition module is used to acquire the collected user's iris information;

[0069] A determination module, used to determine the screen position information corresponding to the user's iris information according to the pre-stored one-to-one correspondence between the iris information and the screen position information, and record it as the target position information;

[0070] The control module is used to control the screen in the head mounted display device to move to a position corresponding to the target position information.

[0071] The iris information and the corresponding screen position information satisfy the condition that when the screen is at the position corresponding to the screen position information, the user corresponding to the iris information can clearly see the picture displayed on the screen.

[0072] Furthermore, the head mounted display device control apparatus may further include:

[0073] A collection module is used to collect and store the user's iris information;

[0074] A storage module, used to store the current screen position information after receiving the confirmation signal of the screen position, and establish a corresponding relationship between the stored screen position information and the iris information;

[0075] The confirmation signal indicates that the user can clearly see the image displayed on the screen.

[0076] Furthermore, the control module can be specifically used for:

[0077] Get the current position information of the screen;

[0078] If the current position information is inconsistent with the target position information, the screen is controlled to move to the position corresponding to the target position information.
