[0032] The following detailed description of the application will be made in connection with Figures 1-13 a head-mounted device according to embodiments of the application.

[0033] As shown in Figure 1 , the present application provides a head-mounted device 100. Wherein, the head-mounted device 100 comprises a main body 102, a lens assembly 110 and a power detection assembly 118.

[0034] Further, as shown in Figure 1 , Figure 2 and Figure 4 , the main body 102 is provided with a mounting slot 104, and the mounting slot 104 is provided with a first electrode contact 106 and a second electrode contact 108.

[0035] Further, the lens assembly 110 is detachably arranged in the mounting slot 104.

[0036] Specifically, when the user uses the lens assembly 110 on the head-mounted device 100, the user can gently slide the lens assembly 110 along the mounting slot 104 on the main body 102 of the head-mounted device 100 until the lens assembly 110 enters the correct position of the mounting slot 104. Wherein, in the process of the lens assembly 110 entering the mounting slot 104, the lens assembly 110 can be attracted by the magnetic attraction device in the mounting slot 104, so that the lens assembly 110 is fixed. Once the lens assembly 110 reaches the correct position and is fixed, the user will feel a certain resistance to remind the user that the lens assembly 110 has been correctly installed, and at the same time, the lens assembly 110 will be firmly installed in the mounting slot 104 to ensure that it will not move or loosen.

[0037] Further, as shown in Figure 1 , Figure 2 , Figure 3 and Figure 7 , the lens assembly 110 comprises a resistance assembly 112, a third electrode contact 114 and a fourth electrode contact 116, and the resistance assembly 112 is used to connect between the third electrode contact 114 and the fourth electrode contact 116.

[0040] Further, after the resistance assembly 112 and the power detection assembly 118 form a path, the power detection assembly 118 can start to work, and the power detection assembly 118 is configured to measure a resistance signal of the resistance assembly 112 and determine the power information of the lens assembly 110 according to the resistance signal. Specifically, once the resistance assembly 112 and the power detection assembly 118 form a path, the resistance value of the resistance assembly 112 will cause a change in current, and this changed current will be transmitted through the circuit to the power detection assembly 118, and the power detection assembly 118 will detect the change in the value of this current and calculate the resistance value of the resistance assembly 112 according to the change in the value of this current to obtain the resistance signal of the resistance assembly 112.

[0041] In this way, by arranging the resistance assembly 112 on the lens assembly 110, after the lens assembly 110 is installed on the main body 102, that is, in the case of using an external lens assembly 110 for the head-mounted device 100, the head-mounted device 100 can automatically identify the power information of the installed lens assembly 110 by measuring the resistance value of the resistance assembly 112, without the need for the user to manually mark or remember the power information of the lens assembly 110, thereby solving the problem that the lens assembly 110 cannot be matched with the user's vision due to the placement confusion of the lens assembly 110. Moreover, the user does not need to frequently wear and take off the head-mounted device 100 and replace the lens assembly 110 installed on the main body 102 to select a lens assembly 110 that matches the user's vision, thereby simplifying the user's operation of selecting the lens assembly 110 and improving the user's convenience of using the lens assembly 110 on the head-mounted device 100.

[0042] According to the head-mounted device 100 provided by the embodiment of the present application, the head-mounted device 100 comprises a main body 102, a lens assembly 110 and a degree detection assembly 118.

Further, when the lens assembly 110 is arranged in the mounting slot 104, the first electrode contact 106 is connected with the third electrode contact 114, and the second electrode contact 108 is connected with the fourth electrode contact 116, so that the resistance assembly 112 and the degree detection assembly 118 form a path. The degree detection assembly 118 is used for measuring a resistance signal of the resistance assembly 112, and determining degree information of the lens assembly 110 according to the resistance signal. According to the head-mounted device 100 provided by the embodiment of the present application, the resistance assembly 112 is arranged on the lens assembly 110. When the lens assembly 110 is used, the resistance signal of the resistance assembly 112 is measured, and the degree information of the lens assembly 110 is determined. In this way, the degree of the lens assembly 110 connected to the head-mounted device 100 can be determined without frequently wearing and taking off the head-mounted device 100, and the efficiency of using the lens assembly 110 connected to the head-mounted device 100 is improved.

[0043] According to some embodiments of the present application, optionally, as shown in Figure 3 and Figure 7 , the lens assembly 110 further comprises a frame 120 and a lens 122.

[0044] The third electrode contact 114 and the fourth electrode contact 116 are arranged on the frame 120.

[0045] Further, the lens 122 is arranged in the frame 120, and at least one lens 122 is arranged in each frame 120.

In this way, the resistance element 124 is arranged on the lens assembly 110, and when the head-mounted device 100 uses the externally connected lens assembly 110, the head-mounted device 100 can automatically identify the power information of the installed lens assembly 110 by measuring the resistance value of the resistance element 124, so as to facilitate the user to select the lens assembly 110 that matches the user's eyesight, and the convenience of the user to use the lens assembly 110 on the head-mounted device 100 is improved.

[0052] According to some embodiments of the present application, optionally, as shown in Figure 3 The resistance assembly 112 is arranged in the frame 120.

[0053] The wire 126 in the resistance assembly 112 is connected between the third electrode contact 114 and the first end of the resistance element, between the second end of the resistance element 124 and the fourth electrode contact 116, so that the resistance element 124 is connected between the third electrode contact 114 and the fourth electrode contact 116, and the resistance element 124 is connected to the circuit path, so as to facilitate the measurement of the resistance value of the resistance element 124.

[0054] Further, when the resistance assembly 112 is arranged in the frame 120, the resistance assemblies 112 with different resistance values correspond to the lens assemblies 110 with different powers, and the correspondence between the resistance values of the resistance assemblies 112 and the power information is stored in the head-mounted device 100.

[0055] According to the head-mounted device 100 of the embodiments of the present application, the resistance component 112 is arranged in the frame 120, and the wires 126 are connected between the third electrode contact 114 and the first end of the resistance element 124, and between the second end of the resistance element 124 and the fourth electrode contact 116. In this way, the resistance component 112 is built in the lens component 110, and in the case that the head-mounted device 100 uses an external lens component 110, the head-mounted device 100 can automatically identify the degree information of the installed lens component 110 by measuring the resistance value of the resistance component 112, so as to facilitate the user to select the lens component 110 matching the user's own eyesight, and improve the convenience of the user to use the lens component 110 on the head-mounted device 100.

[0056] According to some embodiments of the present application, as shown in Figure 7 Optionally, the resistance component 112 is detachably mounted on the frame 120.

[0061] Further, in the case that the resistance component 112 is detachably mounted on the frame 120, the resistance components 112 with different resistance values correspond to the lens components 110 with different degrees, and the resistance component 112 is used in combination with the corresponding lens component 110. In actual application process, the user can customize and modify the degree information associated with the resistance components 112 with different resistance values, so as to mark the degree of the lens component 110 in a personalized manner in the case that multiple people use the head-mounted device 100.

[0062] According to the head-mounted device 100 of the embodiments of the present application, the resistance component 112 is detachably mounted on the frame 120; the resistance component 112 further comprises: a fifth electrode contact 128 connected with the resistance element 124 through the wire 126, the fifth electrode contact 128 corresponding to the third electrode contact 114; a sixth electrode contact 130 connected with the resistance element 124 through the wire 126, the sixth electrode contact 130 connected with the resistance element 124 through the wire 126. In this way, the resistance component 112 is externally connected on the lens component 110, which facilitates automatic identification of the power information of the installed lens component 110 through the resistance value of the resistance component 112, facilitates the user to select the lens component 110 matching the user's eyesight, and improves the convenience of the user to use the lens component 110 on the head-mounted device 100; on the other hand, it is convenient for the user to customize the power information associated with the resistance component 112, and facilitates the user to mark the power of the lens component 110 individually.

[0063] According to some embodiments of the present application, as shown in Figure 7 When the resistance component 112 is mounted on the frame 120, the third electrode contact 114 and the fifth electrode contact 128 are connected, and the fourth electrode contact 116 and the sixth electrode contact 130 are connected.

[0064] In this way, the resistance element 124 is connected between the third electrode contact 114 and the fourth electrode contact 116 through the fifth electrode contact 128 and the fourth electrode contact 116, thereby forming a path with the power detection component 118, which facilitates automatic identification of the power information of the installed lens component 110 by detecting the resistance value of the resistance element 124.

[0065] According to the head-mounted device 100 of the embodiments of the present application, when the resistance component 112 is mounted on the frame 120, the third electrode contact 114 and the fifth electrode contact 128 are connected, and the fourth electrode contact 116 and the sixth electrode contact 130 are connected, so that the resistance element 124 is connected between the third electrode contact 114 and the fourth electrode contact 116. In this way, the resistance component 112 is externally connected on the lens component 110, which can automatically identify the power information of the installed lens component 110 by measuring the resistance value of the resistance component 112 in the case of using the lens component 110 on the head-mounted device 100, facilitates the user to select the lens component 110 matching the user's eyesight, and improves the convenience of the user to use the lens component 110 on the head-mounted device 100.

[0066] According to some embodiments of the present application, as shown in Figure 2 The power detection component 118 comprises a sensor 132, an analog-to-digital converter 134 and a microcontroller 136.

[0067] The sensor 132 is connected to both the first electrode contact 106 and the second electrode contact 108, and is configured to measure a resistance signal of the resistance assembly 112.

[0068] Specifically, after the lens assembly 110 is installed in the mounting slot 104, as shown in FIG. 2, the first electrode contact 106 and the third electrode contact 114 are connected, the second electrode contact 108 and the fourth electrode contact 116 are connected, and the sensor 132 forms a path with the resistance assembly 112, and a current flows through the resistance element 124 and the wire 126. Figure 5 The resistance value of the resistance element 124 is different, which results in different current values. The current values are obtained and measured by the sensor 132. The sensor 132 calculates the resistance value of the resistance element 124 based on the change of the current value, and obtains the resistance signal of the resistance assembly 112.

[0069] In actual application, as shown in FIG. 3, the main body 102 is provided with a rated power supply 142, and the rated power supply 142 is connected to the sensor 132, the first electrode contact 106 and the second electrode contact 108, so as to provide appropriate power source for the power detection assembly 118, and to ensure that the power detection assembly 118 has stable power supply when working. Figure 5

[0070] Further, the analog-to-digital converter 134 is connected to the sensor 132, and is configured to convert the resistance signal measured by the sensor 132 into a digital signal.

[0071] Specifically, after the sensor 132 obtains the resistance signal, the sensor 132 transmits the resistance signal to the analog-to-digital converter 134. The analog-to-digital converter 134 converts the analog and continuous resistance signal into a discrete digital signal. Specifically, after receiving the resistance signal, the analog-to-digital converter 134 samples the resistance signal, i.e. samples the resistance signal at a certain time interval to obtain a plurality of sample values. Further, the analog-to-digital converter 134 quantizes the plurality of sample values, i.e. divides the continuous resistance signal into a plurality of discrete levels, and converts the continuous resistance signal into a corresponding digital signal, so as to process and store the digital signal.

[0072] Further, the microcontroller 136 is connected to the analog-to-digital converter 134, and is configured to receive the digital signal converted by the analog-to-digital converter 134, and determine the power information of the lens assembly 110 according to the digital signal.

[0073] ​Specifically, after obtaining the digital signal, the analog-to-digital converter 134 transmits the digital signal to the microcontroller 136, and the microcontroller 136 receives the digital signal and performs a preset conversion algorithm. The conversion algorithm can convert the digital signal into corresponding degree information according to a preset relationship between the resistance value (i.e., the numerical value of the digital signal) and the degree information.

[0074] In actual application, the microcontroller 136 can also perform relevant data processing, storage or transmission on the digital signal, and the microcontroller 136 can also interact with other modules on the head-mounted device 100 to display the degree information or perform further operations.

[0075] According to the head-mounted device 100 of the embodiments of the present application, the degree detection assembly 118 includes the sensor 132, the analog-to-digital converter 134 and the microcontroller 136. The sensor 132 is connected with the first electrode contact 106 and the second electrode contact 108, and is used to measure the resistance signal of the resistance assembly 112. The analog-to-digital converter 134 is connected with the sensor 132, and is used to convert the resistance signal into a digital signal. The microcontroller 136 is connected with the analog-to-digital converter 134, and is used to determine the degree information of the lens assembly 110 according to the digital signal. In this way, in the case that the head-mounted device 100 uses an external lens assembly 110, the degree information of the installed lens assembly 110 can be automatically recognized by measuring the resistance signal of the resistance assembly 112, which facilitates the user to select a lens assembly 110 that matches his / her eyesight, and improves the convenience of the user to use the lens assembly 110 on the head-mounted device 100.

[0076] According to some embodiments of the present application, the microcontroller 136 specifically converts the digital signal into the degree information of the lens assembly 110 according to the preset conversion relationship and the digital signal.

[0077] The preset conversion relationship is used to indicate the conversion relationship between different resistance values (i.e., the numerical value of the digital signal) and the degree information.

[0078] In actual application, the preset conversion relationship can be implemented by a preset conversion algorithm. The conversion algorithm can be a pre-set algorithm or an algorithm implemented by programming, and the purpose is to convert the digital signal into actual degree information.

[0079] Specifically, after the microcontroller 136 receives the digital signal output by the analog-to-digital converter 134, the digital signal is transmitted to the conversion algorithm inside the microcontroller 136. The microcontroller 136 performs the conversion algorithm to perform a series of mathematical operations and conversion operations on the digital signal according to the preset conversion relationship and the calibration data, such as numerical value interpolation, correction and unit conversion, etc., to convert the digital signal into the degree information of the lens assembly 110.

[0080] For example, the resistance value 10Ω corresponds to a myopia degree of 200°, and after the microcontroller 136 receives the digital signal corresponding to the resistance value 10Ω, the microcontroller 136 obtains the current degree of the lens assembly 110 as 200° by performing a series of mathematical operations and conversion operations on the digital signal.

[0081] According to the head-mounted device 100 provided by the embodiments of the present application, the microcontroller 136 is specifically configured to: convert the digital signal into the degree information of the lens assembly 110 according to the digital signal and the preset conversion relationship. In this way, the degree information of the installed lens assembly 110 is automatically identified, which facilitates the user to select the lens assembly 110 that matches the user's own vision, and improves the convenience of the user to use the lens assembly 110 on the head-mounted device 100.

[0082] According to some embodiments of the present application, optionally, as shown in Figure 2 The head-mounted device 100 further includes a processor 138.

[0083] The processor 138 is arranged in the main body 102, and the processor 138 is connected with the microcontroller 136.

[0084] Further, the microcontroller 136 is further configured to transmit the digital signal to the processor 138.

[0085] Specifically, after the microcontroller 136 receives the digital signal output by the analog-to-digital converter 134, the microcontroller 136 transmits the digital signal to the processor 138 for processing through a specific communication protocol.

[0086] Further, after the processor 138 receives the digital signal, the processor 138 compares the digital signal with data in a register, a buffer or a storage unit of the processor 138 through an internal algorithm to find the degree setting information corresponding to the digital signal, so as to determine whether the digital signal is set, and in the case that the resistance assembly 112 is detachably mounted on the lens frame 120, it can be determined whether the resistance assembly 112 is assembled on the lens assembly 110 for the first time. Specifically, in the case that the processor 138 finds the degree setting information corresponding to the digital signal, it is indicated that the digital signal is set, that is, it is indicated that the resistance assembly 112 is not assembled on the lens assembly 110 for the first time. At this time, the processor 138 will retrieve the degree setting information corresponding to the digital signal stored in the processor 138, and take the degree setting information as the degree information of the lens assembly 110.

[0087] In the process of searching the degree setting information corresponding to the digital signal by the processor 138, the storage system and the database inside the processor 138 can be involved. The processor 138 processes and converts the acquired digital signal, and maps it to the degree setting information set by the user before, which can include a series of algorithms and conversion processes to ensure the accurate mapping and conversion between the digital signal and the degree information.

[0088] The head-mounted device 100 according to the embodiments of the present application further includes a processor 138 arranged in the main body 102, the processor 138 is connected with the microcontroller 136, and the microcontroller 136 is further configured to transmit the digital signal to the processor 138; the processor 138 is specifically configured to: search the degree setting information corresponding to the digital signal; and in the case that the degree setting information corresponding to the digital signal is found, take the degree setting information as the degree information of the lens assembly 110. In this way, the degree information of the installed lens assembly 110 is automatically identified, which facilitates the user to select the lens assembly 110 matching the user's own eyesight, and improves the convenience of the user using the lens assembly 110 on the head-mounted device 100.

[0089] According to some embodiments of the present application, optionally, as shown in Figure 2 The head-mounted device 100 further includes a display screen 140.

[0090] The display screen 140 is arranged on the main body 102.

[0091] In the case that the degree setting information corresponding to the digital signal is not found by the processor 138, it indicates that the digital signal has not been set, i.e., the resistor assembly 112 is assembled on the lens assembly 110 for the first time. At this time, the processor 138 displays the guide information through the display screen 140 to prompt and guide the setting of the degree information associated with the current resistor assembly 112 and the digital signal corresponding thereto. On this basis, the user can set the degree information associated with the current resistor assembly 112 and the digital signal corresponding thereto based on the guiding indication of the guide information through the button, the touch screen or the voice command and the like. Further, the display screen 140 can receive the user input, and the processor 138 further sets the degree information associated with the digital signal and the resistor assembly 112 according to the user input, and the degree information is the degree setting information corresponding to the digital signal. After the processor 138 sets the degree information associated with the digital signal and the resistor assembly 112, the association relationship between the digital signal and the degree information is stored in the storage system inside the processor 138, such as the database, the register, the buffer or the storage unit inside the processor 138, to ensure the reliability and safety of the association relationship. Moreover, the processor 138 also stores the degree setting information corresponding to the set digital signal, so as to directly call the degree setting information subsequently.

[0092] According to the head-mounted device 100 provided by the embodiment of the present application, the display screen 140 is arranged on the main body 102, and the processor 138 is further configured to: in the case where the diopter setting information corresponding to the digital signal is not found, display the guide information through the display screen 140; and the display screen 140 is further configured to: receive the user input; and the processor 138 is further configured to: determine the diopter information corresponding to the digital signal and the resistance component 112 according to the user input. In this way, the user can customize the diopter information associated with the resistance component 112, and the user can mark the diopter of the lens component 110 individually.

[0093] According to some embodiments of the present application, the processor 138 is further configured to compare the diopter information and the historical diopter data.

[0094] The diopter information can be calculated by the processor 138, or the diopter information can be transmitted to the processor 138 by the microcontroller 136.

[0095] In the case where the diopter information is transmitted to the processor 138 by the microcontroller 136, after the microcontroller 136 calculates the diopter information of the lens component 110, the microcontroller 136 stores the diopter information in the register or buffer of the microcontroller 136, and then transmits the diopter information to the processor 138 through a specific communication interface supported by the processor 138, such as Bluetooth, Universal Serial Bus (USB) or other custom communication protocol interface.

[0096] For example, the microcontroller 136 transmits the diopter information to the processor 138 through Bluetooth. The microcontroller 136 sends an instruction to the Bluetooth module to transmit the diopter information of the lens component 110, and then sends the diopter information to the processor 138 through the Bluetooth connection. For other wireless communication protocols, the corresponding communication means is used to realize the transmission of the diopter information.

[0097] Further, the historical diopter data can be the ideal diopter information after user calibration, user personal preference setting information or other related data previously stored in the processor 138. In actual application, the historical diopter data can be the diopter information or diopter setting information recorded by the processor 138 last time.

[0098] On this basis, after the processor 138 obtains the diopter information of the lens component 110, the processor 138 stores the diopter information in the buffer or register of the processor 138, reads the historical diopter data previously stored, and then takes the historical diopter data as a reference value to judge whether the diopter information is consistent with the historical diopter data through a series of judgments and comparisons.

[0099] In the process of judging whether the degree information is consistent with the historical degree data, the difference between the degree information and the historical degree data can be calculated, and then whether the degree information is consistent with the historical degree data can be judged according to the difference; or, whether the degree information is consistent with the historical degree data can be judged by comparing whether the values of the degree information and the historical degree data are equal. The specific manner of judging whether the degree information is consistent with the historical degree data is not limited here.

[0100] Further, the display screen 140 can also be used to display the degree information of the lens assembly 110. In actual application, the display screen 140 can present the degree information of the lens assembly 110 to the user in the form of numbers, graphics or other symbols, so that the user can check the degree of the lens assembly 110 installed on the head-mounted device 100. In this way, the user can directly know the degree of the lens assembly 110 installed on the head-mounted device 100 without wearing the head-mounted device 100, which provides the user with real-time and accurate degree information prompt, and facilitates the user to quickly know whether the current degree information matches the user's vision, so as to ensure that the user can quickly select the correct lens assembly 110 in the scenario where multiple people use the head-mounted device 100, and improve the efficiency of using the external lens assembly 110 on the head-mounted device 100.

[0101] Specifically, in the case where the processor 138 determines that the degree information is consistent with the historical degree data, the display screen 140 will display the degree information, so that the user can intuitively understand the degree information of the lens assembly 110 currently used by the head-mounted device 100. Further, in the case where the processor 138 determines that the degree information is inconsistent with the historical degree data, the display screen 140 will display the degree information and a prompt information to inquire whether the user replaces the lens assembly 110.

[0102] The degree information of the lens assembly 110 will be displayed on the display screen 140 for a short time and for a long enough time so that the user can see it clearly. After the user confirms the degree information of the current lens assembly 110, the user can provide confirmation feedback to the head-mounted device 100 by pressing a button or performing eye movements, to inform the head-mounted device 100 that the user has known the current degree information of the lens assembly 110.

[0103] Further, in actual application, the prompt information can be presented in the form of subtitles, icons or indication arrows, etc. to inform the user that the current lens assembly 110 has inconsistent diopter information with the historical diopter data, and to ask the user's attitude towards this situation. On this basis, the head-mounted device 100 will wait for the user's response to the prompt information. The user can feed back to the head-mounted device 100 whether to replace the lens assembly 110 by pressing the button, making eye movements or using voice control, etc. In the case that the user chooses to replace the lens assembly 110, the head-mounted device 100 can provide corresponding guidance for the user through the display screen 140 to inform the user how to replace the lens assembly 110, or the head-mounted device 100 can indicate that it will automatically adjust to adapt to the diopter of the current lens assembly 110.

[0104] According to the head-mounted device 100 of the embodiment of the present application, the processor 138 is further configured to compare the diopter information with the historical diopter data; and the display screen 140 is further configured to display the diopter information when the diopter information is consistent with the historical diopter data, and display the diopter information and the prompt information when the diopter information is inconsistent with the historical diopter data. In this way, the user can directly know the diopter of the lens assembly 110 installed on the head-mounted device 100 without wearing the head-mounted device 100, which provides the user with real-time and accurate diopter information prompt, and facilitates the user to quickly know whether the current diopter information matches the user's vision, so as to ensure that the user can quickly select the correct lens assembly 110 in the scenario that multiple people use the head-mounted device 100, and improve the efficiency of using the external lens assembly 110 on the head-mounted device 100.

The method can specifically include the following S402-S408:

[0133] S402: Measure the resistance signal of the resistance component.

In this way, the user does not need to frequently wear and remove the head-mounted device to determine the diopter of the external lens assembly used on the head-mounted device, thereby improving the efficiency of using the external lens assembly on the head-mounted device.

[0143] In the embodiments of the present application, S406 can specifically include S406a as follows:

[0144] S406a: converting the digital signal into the diopter information of the lens assembly according to the digital signal and a preset conversion relationship.

[0145] The preset conversion relationship is used to indicate the conversion relationship between different resistance values (i.e. the numerical value of the digital signal) and the diopter information.
