[0049] In order to have a clearer understanding of the technical features, objects and effects of the embodiments of the present application, the specific implementation manners of the embodiments of the present application will be described with reference to the drawings.

[0050] In this document, "illustrative" means "serving as an example, instance, or illustration." Any implementation described herein as "illustrative" is not necessarily to be construed as preferred or advantageous over other implementations.

[0051] For the sake of brevity, the drawings of the various aspects will not be described in detail in this document. Also, for the sake of brevity, the drawings will often only show portions of the apparatuses and / or processes being presented and described. However, the skilled artisan will recognize that the apparatuses and / or processes often include other components and / or steps not shown or described in the drawings.

[0052] As an access medium of virtual reality and / or mixed reality, the head-mounted display device or head-mounted display device can generally include a front-end assembly, a connecting band 10 and a rear-end assembly. The front-end assembly can include a main screen, an optical system and a protective shell, etc. The optical system is part of a virtual image generation system, and the display content of the main screen is presented to the wearer's left and right eyes through a pair of eyepieces of the optical system, and the wearer can perceive the virtual content.

[0053] The type of main screen can be adjusted according to the application of the glasses-type virtual reality display device in the virtual reality system, the augmented reality system or the mixed reality system. The optical system includes optical elements for changing the optical path of the display, such as lenses, light guides or prisms, etc.

[0054] The front-end assembly can generally include a front frame, a main board and an internal display assembly, both of which can be installed in the front frame. The main board, as the main control mechanism of the head-mounted display device, can be provided with integrated circuits, soldered wires, memories, CPUs, GPUs, inertial sensors and other components, and can be electrically connected to power management components, communication components, image capture components, infrared receiving components, ultrasonic components, etc. to collectively complete the basic functions of the virtual reality device. The communication components can further include Bluetooth, WiFi, antennas, baseband communication chips, etc. and can be provided on the main board or the front frame as needed, and will not be described in detail. The power supply assembly can generally include a battery and a power manager, etc. and can be provided in the front frame or in the rear-end assembly with rear pillows to provide power support for the overall device.

[0055] Switches, function switching buttons and other components can also be provided on the front frame to facilitate users to control the on-off and running state of the entire head-mounted display device through these buttons while wearing.

[0056] The internal display assembly is electrically connected to the main board, and the internal display mechanism is used to present virtual content to the wearer's eyes, which generally includes one or two display screens and two optical lenses such as Fresnel lenses, pancake lenses, etc. Under the control of the main board, the virtual content is projected onto the display screen and further transmitted through the two optical lenses to the wearer's eyes, forming a stereoscopic virtual content.

[0057] The rear-end assembly can be located behind the wearer's head when worn, and a length-adjustable connecting band 10 is connected between the front frame and the rear-end assembly. The connecting band 10 can include a top connecting band 10 and an edge connecting band 10, wherein the edge connecting band 10 can adjust the tightness of the user when wearing, and the top connecting band 10 can hang the head-mounted display device on the user's head. It can balance the weight of the front and rear and increase the comfort of the user when wearing.

[0058] When the head-mounted display device is running, the operating system of the device is in a working state, and the working information of the device can be presented to the user through the internal display assembly. The user can connect and pair with external interactive devices such as handles, wristbands, etc. through the communication components of the head-mounted display device to control the head-mounted display device.

[0059] All information such as device running information, power information, display content, etc. can be displayed through the internal display assembly. In this way, the user needs to view all the information in the on state through the home screen, and the user needs to be in the wearing state to view, which is inconvenient for the user.

[0060] This application provides a head-mounted display device. In addition to the aforementioned inner display component, an outer display mechanism, also referred to as an outer display component, can be provided on the outer surface of the head-mounted display device for displaying preset information.

The external display mechanism includes an external display screen 51 electrically connected to the motherboard. The external display screen 51 is located on the outer surface of the head-mounted display device and is used to display preset information.

[0062] With the above technical solution, the external display screen 51 faces outward and can be used to display some information of the head-mounted display device. This information can be viewed without wearing the head-mounted display device, which is more convenient than the related technologies where users must wear the head-mounted display device to view information through the internal display component.

[0063] The connecting strap 10 is adjustable in length and is connected between the front frame and the rear component, thereby forming a loop to be fitted over the wearer's head. The length of the connecting strap 10 can be adjusted to suit different wearers.

[0064] The front-end component may also include a light-shielding mask to block out light and reduce the influence of external light when the internal display mechanism displays content to the wearer's eyes, as is known to those skilled in the art. The internal display mechanism includes an electronic display screen and an optical system to achieve a virtual reality presentation effect, as is known to those skilled in the art.

[0065] The external display screen 51 can display preset information such as: current battery percentage, charging status, calorie data, date and time, currently running application name, application name, system upgrade progress, etc. In this way, the external display screen 51 and the internal display mechanism have a clear division of labor, allowing relevant information to be viewed through the external display screen 51 without needing to wear or remove it.

[0066] It should be noted that in the present application, "front, back, left, right" are defined based on the state of the user wearing the head-mounted display device, with the front-end component in front of the wearer's eyes and the rear-end component 20 behind the wearer's head. "Inside, outside" is based on the head-mounted display device itself, with the side of the rear-end component 20 facing the front-end component being the inside, and the side facing away from the front-end component being the outside.

[0067] In a possible embodiment, the outer display screen 51 can be located on the outer surface of the front frame, for example embedded in any position of the front surface of the front frame, and can be electrically connected to the mainboard through a circuit inside, which can be square, rhombus, triangle, oval, racetrack, circular, etc. The shape is preferably circular, and is preferably arranged at the top center of the front part of the front frame. Of course, it can also be arranged on the side of the front frame, and will not be described in detail. When the outer display screen 51 is working, the user does not need to wear the head-mounted display device, and can check the part of the running status of the device, such as the power, network connection status, etc. through the outer display screen 51. In an embodiment, the user's motion state, step count, etc. or other information, such as verification information, payment information, etc. generated when the user performs game download, account login, etc. through the head-mounted display device can also be displayed, and will not be described in detail.

[0068] In a possible embodiment, the outer display screen 51 can be located on the connecting band 10, which can also be called a headband. The headband can be made of soft material or hard shell material, and can be arranged with a circuit cable inside. The part of the device in the rear-end component can be electrically connected to the corresponding component in the front-end component to realize signal, data, power, etc. transmission.

[0069] When the part of the connecting band 10 surrounding the side of the head (i.e. the above-mentioned edge connecting band) is made of hard shell material, in a possible embodiment, the outer display screen 51 can be embedded in any position of the part surrounding the side of the head, and can be electrically connected to the mainboard through a circuit inside.

When the outer display screen 51 is working, the user does not need to wear the head-mounted display device, and can check the part of the running status of the device, such as the power, network connection status, etc. through the outer display screen 51. In an embodiment, the user's motion state, step count, etc. or other information, such as verification information, payment information, etc. generated when the user performs game download, account login, etc. through the head-mounted display device can also be displayed, and will not be described in detail.

[0070] In the case that the part of the connection band 10 for surrounding the head side (i.e. the above-mentioned edge connection band) is of a soft band material, in one possible implementation, the external display screen 51 can be arranged in any position of the part for surrounding the head side in a form of suspension or wrapping by a gel material, and the inside can be electrically connected to the main board by a wire, and the shape can be square, rhombus, triangle, ellipse, track, circle, etc. When the external display screen 51 is working, the user does not need to wear the head-mounted display device, and can check the part of the running status of the device, such as the power, the network connection status, etc. through the external display screen 51. In one implementation, the user's motion state, the step count, etc. or other information, such as the generated verification information, payment information, etc. when the user is downloading the game, logging in the account, etc. through the head-mounted display device, can also be displayed, and details are not described herein.

[0071] The above-mentioned implementation of the external display screen 51 and the connection band 10 is only an example, and should not be understood as a limitation. When the connection band 10 is of a soft material, the external display screen 51 can also be wrapped by a plastic, PU, etc. material and arranged on the connection band 10, and details are not described herein.

[0072] In another possible implementation, the rear-end component 20 can include an outer panel 21, a skeleton 22, and an inner panel, the inner panel and the outer panel 21 are respectively arranged on the inner side and the outer side of the skeleton 22, and an outer accommodating cavity is formed between the outer panel 21 and the skeleton 22; the outer panel 21 is provided with a mounting groove 210 on the outer surface, the mounting groove 210 is located in the outer accommodating cavity, the external display screen 51 is fixed in the slot of the mounting groove 210, and the mounting groove 210 is provided with a first avoiding hole 201 on the bottom wall; the external display mechanism further includes a comprehensive wire harness 54, the comprehensive wire harness 54 passes through the first avoiding hole 201, one end is electrically connected to the external display screen 51, and the other end is electrically connected to the main board.

[0073] In the case of the above-mentioned technical solution, on the one hand, when wearing, the inner panel 21 contacts the back of the wearer's brain, and the external display screen 51 is located on the outer panel 21, so that the wearing comfort is not affected, and a third party can also check the relevant information on the external display screen 51 in the case of wearing, which is very convenient; on the other hand, the external display screen 51 is arranged on the rear-end component, so that the weight of the front-end component can be balanced, and the wearing comfort can be improved; on the other hand, the comprehensive wire harness 54 can electrically connect the main board and the external display screen 51 by passing through the first avoiding hole 201 on the bottom wall of the mounting groove 210, the mounting groove 210 can provide a protection space for the external display screen 51, so that the external display screen 51 is not affected by other components in the outer accommodating cavity, and the stable performance of the external display screen 51 is ensured. In addition, the skeleton 22 can play a supporting role, so that the structural strength of the rear-end component is large.

[0074] In a possible embodiment, the head-mounted display device can further comprise an adjusting knob 30 and a mounting bracket 40; the mounting bracket 40 is located in a mounting hole of the adjusting knob 30 and fixedly connected to the bottom wall of the mounting groove 210, the adjusting knob 30 is rotatably mounted in the mounting groove 210, and the shape of the adjusting knob 30 is preferably circular for the convenience of user operation; the outer display screen 51 is mounted on the mounting bracket 40, and the shape of the outer display screen 51 corresponds to the shape of the adjusting knob 30, for example, when the shape of the adjusting knob 30 is circular, the shape of the outer display screen 51 is also circular, and the radius of the outer display screen 51 is smaller than the radius of the adjusting knob 30, so as to closely fit the adjusting knob 30 and ensure the stability of the structure.

[0075] In the case of the above technical solution, the adjusting knob 30 is rotatably sleeved outside the mounting bracket 40, thereby being sleeved outside the outer display screen 51, the outer display screen 51 is fixed on the rear-end assembly 20 through the mounting bracket 40, the adjusting knob 30 is freely rotated alone to adjust the length of the connecting belt 10, and the outer display screen 51 remains fixed. The comprehensive wire harness 54 passes through the third avoiding hole 401 of the mounting bracket 40 and the first avoiding hole 201 of the mounting groove 20 to electrically connect the outer display screen 51 and the main board together, so that the display screen 51 can display relevant information; therefore, the outer display screen 51 is nested in the adjusting knob 30, space can be saved, and the appearance can be improved. Since the mounting bracket 40 is fixedly connected to the bottom wall of the mounting groove 210, the first avoiding hole 201 is located in the side wall of the mounting groove 210, and the second avoiding hole 202 is located in the side wall of the mounting groove 210, therefore, the rotation of the adjusting knob 30 will not affect the comprehensive wire harness 54, and the comprehensive wire harness 54 can be stably connected between the outer display screen 51 and the main board.

[0076] In the case of the above technical solution, the adjusting knob 30 is rotatably sleeved outside the mounting bracket 40, thereby being sleeved outside the outer display screen 51, the outer display screen 51 is fixed on the rear-end assembly 20 through the mounting bracket 40, the adjusting knob 30 is freely rotated alone to adjust the length of the connecting belt 10, and the outer display screen 51 remains fixed.

Since the mounting bracket 40 is fixedly connected to the bottom wall of the mounting groove 210, the first avoiding hole 201 is located in the side wall of the mounting groove 210, and the second avoiding hole 202 is located in the side wall of the mounting groove 210, therefore, the rotation of the adjusting knob 30 will not affect the comprehensive wire harness 54, and the comprehensive wire harness 54 can be stably connected between the outer display screen 51 and the main board.

[0077] In a possible implementation, the head-mounted display device further comprises a U-shaped clamping piece 26 and a fastener, the U-shaped clamping piece 26 comprises two wings and a clamping slot 230 between the two wings, each wing has at least one first connecting hole; the mounting bracket 40 is provided with a limiting slot 4220 on the outer side of the protruding first avoiding hole 201; the mounting bracket 40 passes through the clamping slot 230, and the clamping piece is clamped in the limiting slot 4220; the fastener passes through the first connecting hole and is connected with the slot wall of the mounting slot 210. In this way, on the one hand, the U-shaped clamping piece 26 can limit the rotation of the mounting bracket 40 and fixedly connect the mounting bracket 40 to the slot wall of the mounting slot 210, thereby fixedly connecting the mounting bracket 40 to the rear end assembly 20; on the other hand, the U-shaped clamping piece 26 is located outside the mounting slot 210, which can avoid occupying the internal space of the mounting slot 210, thereby reducing the volume of the mounting slot 210. In the case that the wall thickness of the mounting slot 210 is unchanged, the reduction in volume can make the mounting slot 210 have higher structural strength.

[0078] In an example, the number of limiting slots 4220 can be two and symmetrically distributed. In this way, the two wings of the U-shaped clamping piece 26 are clamped in the two limiting slots 4220 respectively, which is beneficial to increase the connection stability.

[0105] S110: In response to a user operation instruction, sensor data of the head-mounted display device is acquired.

[0106] As described above, various sensors can be connected to the mainboard, including a gravity sensor, an acceleration sensor, an IMU, a distance sensor, etc. It should be noted that the user operation instruction herein can be obtained through the hardware of the head-mounted display device itself or through an external device.

[0107] S120: The sensor data of the head-mounted display device is analyzed to obtain display information of the head-mounted display device.

[0108] It should be noted that the data collected by the sensor is complex, and the data collected by the sensor needs to be analyzed and processed, and the display information of the head-mounted display device is obtained according to the result of the analysis and processing.

[0109] S130: The display information is displayed through the outer display screen 51 of the head-mounted display device.

[0110] In the scheme of the embodiment of the present application, the user cannot obtain the state information such as the power of the device without wearing the device, and needs to wear the device to obtain the information, which leads to inconvenience in use. Through the above-mentioned manner, the display of the device state information such as the power can be realized when the user does not wear the device, which facilitates the user to use.

[0111] In a possible implementation, in response to a user operation instruction, the sensor data of the head-mounted display device is acquired, including: acquiring a screen touch signal of the outer display screen 51 of the head-mounted display device; analyzing the screen touch signal of the outer display screen 51 to obtain a touch instruction corresponding to the screen touch signal; and acquiring the sensor data of the head-mounted display device according to the touch instruction.

[0112] It should be noted that the screen touch signal of the outer display screen 51 of the head-mounted display device is acquired, and the screen touch signal of the outer display screen 51 is analyzed to obtain a touch instruction corresponding to the screen touch signal, and then the sensor data of the head-mounted display device is acquired according to the touch instruction. The above method can improve the information processing efficiency of the head-mounted display device. For example, when a user needs to know the network status information of the head-mounted display device, the icon of the network status bar of the outer display screen 51 can be touched to control the head-mounted display device to acquire network sensor data.

[0113] In a possible implementation, as shown in Figure 11A The outer display screen 51 is in communication connection with the mainboard through a board-level bus such as SPI / I2C, and the communication content includes but is not limited to configuration information, version information and image display information. After receiving the touch instruction of the master control chip, the mainboard analyzes and responds, and the main functions of the mainboard include driving screen display, switching image, operating external register, reading touch information and the like.

For example, when a user needs to know the network status information of the head-mounted display device, the corresponding network status bar icon can be selected through the keys of the head-mounted display device to control the head-mounted display device to acquire network sensor data.

[0116] In a possible implementation, the sensor data of the head-mounted display device is parsed to obtain display information of the head-mounted display device, including: the coulometer sensor data of the head-mounted display device is parsed to obtain power data and charging state data; and the power data and the charging state data are displayed through the external display screen 51 of the head-mounted display device.

[0117] It should be noted that, as shown in Figure 11B the coulometer sensor data of the head-mounted display device is parsed to obtain power data and charging state data, and then the power data and the charging state data are displayed through the external display screen 51 of the head-mounted display device.

[0119] It should be noted that, since the external display screen 51 has limited display content, and the power data and the charging state data have more content, they cannot be completely displayed on the external display screen 51 and the display effect is poor. Therefore, the power data and the charging state data can be processed to obtain power display information, and then the power display information is displayed through the external display screen 51 of the head-mounted display device. In this way, the display efficiency of the power information can be improved, and the user experience can be improved.

This can realize display and viewing of the step information and the heat value information when the user does not wear the device, and improve user experience.

[0139] Based on the head-mounted display device provided in the above embodiments, the application further provides embodiments of a head-mounted display device information code display method and device, an electronic device, and a storage medium. The method can include:

[0140] S210: identifying a user operation instruction received by the head-mounted display device.

[0141] It should be noted that the user operation instruction herein can be an operation instruction of a button on the head-mounted display device itself, or an operation instruction transmitted to the head-mounted display device by an external device. Since the user operation instruction received by the head-mounted display device is usually more, the received user operation instruction needs to be identified.

[0142] S220: generating an information code corresponding to the user instruction in response to the user operation instruction.

[0143] It should be noted that the information code herein refers to information coding, that is, a process of assigning a code to an information element in order to facilitate storage, retrieval and use of information. Different codes are used to establish a one-to-one correspondence between the codes and the basic units of various information.

[0144] S230: Display the information code to the external display screen 51 of the head-mounted display device, so that the external device can read the information code through the external display screen 51.

[0145] It should be noted that, as shown in Figure 1 , since the external display screen 51 is located on the rear-end component 20 of the head-mounted display device, after displaying the information code to the external display screen 51 of the head-mounted display device, the external device can read the information code through the external display screen 51. Preferably, as shown in Figure 15 , the information code herein can be a matrix two-dimensional code (also known as a two-dimensional barcode), which refers to a barcode with readability in another dimension based on a one-dimensional barcode, using black and white rectangular patterns to represent binary data, which can obtain the information contained therein after being scanned by a device.

[0146] S230: Receive the response instruction issued by the external device after reading the information code.

[0147] It should be noted that the external device herein refers to a device independent of the head-mounted display device, and the receiving of the response instruction issued by the external device after reading the information code refers to issuing a corresponding response instruction according to the read information code after receiving the reading of the information code.

[0148] S230: Display the information corresponding to the response instruction to the external display screen 51.

[0149] It should be noted that by displaying the information corresponding to the response instruction to the external display screen 51, the display of the interaction result of the external device to the head-mounted display device can be completed.

[0150] In the scheme of the embodiments of the present application, the external display screen 51 is arranged on the rear-end component 20 of the head-mounted display device, and the information code corresponding to the user operation instruction received by the head-mounted display device is generated in response to the user operation instruction, the information code is displayed to the external display screen 51 of the head-mounted display device, so that the external device can read the information code through the external display screen 51, and the response instruction issued by the external device after reading the information code is received; the information corresponding to the response instruction is displayed to the external display screen 51. The above-mentioned manner can be used for specific head-mounted display device objects to interact with the information code and perform payment response or information interaction, thereby improving user experience.

[0151] In a possible implementation, the information code corresponding to the user operation instruction is generated in response to the user operation instruction, including: determining payment information according to the user operation instruction; and encoding the payment information and the head-mounted display device information to generate the information code corresponding to the user operation instruction.

[0152] It should be noted that, in order to avoid information confusion caused by the same information code corresponding to multiple head-mounted display devices, the head-mounted display device information and the payment information determined by the user operation instruction can be encoded to generate a specific head-mounted display device information code corresponding to the user operation instruction.

[0153] For example, the user selects the experience duration of the head-mounted display device through the key of the head-mounted display device, and the head-mounted display device determines the preset payment information corresponding to the experience duration according to the obtained user operation instruction, and encodes the preset payment information and the head-mounted display device information to obtain a specific head-mounted display device information code corresponding to the payment information. Through the above-mentioned manner, the device interaction efficiency can be improved.

[0154] In a possible implementation, the information corresponding to the response instruction is displayed to the external display screen 51, including: identifying the information code to obtain payment information and head-mounted display device information corresponding to the information code; obtaining confirmation information of the payment information and the head-mounted display device information; and displaying the confirmation information to the external display screen 51.

[0155] It should be noted that, in order to avoid the problem of payment failure caused by the error of the information code when the external device identifies and interacts with the information code, the payment information and the head-mounted display device information corresponding to the information code need to be confirmed by the external device, therefore, the payment information and the head-mounted display device information corresponding to the information code can be obtained by identifying the information code, the confirmation information of the payment information and the head-mounted display device information is obtained, and the confirmation information is displayed to the external display screen 51. Through the above-mentioned manner, the security of device interaction can be improved.

[0156] In a possible implementation, the method further includes: identifying the information code to obtain head-mounted display device verification information corresponding to the information code; and controlling the head-mounted display device when the external device meets the head-mounted display device verification information.

[0157] It should be noted that, in order to avoid multiple external devices interacting with the same head-mounted display device when the external device interacts with the head-mounted display device, the information of the external device needs to be verified, and the external device controls the head-mounted display device when the external device meets the head-mounted display device verification information. Through the above-mentioned manner, the device interaction efficiency can be improved.

[0158] In a possible implementation, when the external device meets the verification information of the head-mounted display device, the head-mounted display device is controlled, including: when the external device meets the verification information of the head-mounted display device, transmitting the input instruction obtained by the external device to the head-mounted display device.

[0159] It should be noted that, since the head-mounted display device has less functions realized by the self keys, when a complex function needs to be realized, the head-mounted display device needs to be controlled according to the external information, therefore, the input instruction obtained by the external device can be transmitted to the head-mounted display device.

[0160] For example, when the user needs to set the software of the head-mounted display device, the control setting information can be transmitted to the head-mounted display device by the external device. In this way, the device interaction efficiency can be improved.

[0161] In a possible implementation, when the external device meets the verification information of the head-mounted display device, the input instruction obtained by the external device is transmitted to the head-mounted display device, including: when the external device meets the verification information of the head-mounted display device, obtaining the text input information of the external device; and transmitting the text input information to the head-mounted display device as the input instruction.

[0162] It should be noted that, the text information of the head-mounted display device is usually input by the joystick of the head-mounted display device, and this input method is low in efficiency, therefore, the text input information of the external device can be obtained, and the text input information is transmitted to the head-mounted display device as the input instruction, so as to realize the efficient input of the text information. In this way, the device interaction efficiency can be improved.

[0163] In a possible implementation, when the external device meets the verification information of the head-mounted display device, the head-mounted display device is controlled, including: when the external device meets the verification information of the head-mounted display device, projecting the interface of the head-mounted display device to the external device; obtaining the interface operation instruction of the head-mounted display device by the external device; and controlling the head-mounted display device according to the interface operation instruction.

[0164] It should be noted that, the head-mounted display device is usually controlled by the joystick and the physical keys connected thereto, and this control method is single in function, therefore, the interface of the head-mounted display device can be projected to the external device, the head-mounted display device obtains the interface operation instruction of the head-mounted display device by the external device, and the head-mounted display device is controlled according to the interface operation instruction.

[0165] For example, when performing an extended reality (XR) game experience, a complex setting of game content is required, and the control interface of the head-mounted display device can be projected to an external device, and the projected control interface is controlled by the external device, and the head-mounted display device performs corresponding control response. Through the above-mentioned mode, the device interaction efficiency can be improved.
