[0002] With the rapid development of smart wearable technology, smart glasses, as a new generation of wearable terminals, are evolving from single information display devices into comprehensive devices that integrate vision correction, voice interaction and other functions.

[0087] A camera 40 can also be added to this new type of smart glasses. It is installed at the front end of the right temple of the eyeglass frame 10 and electrically connected to the main control module 305 for collecting image and video data.

[0088] Example 1

[0089] In this embodiment:

[0090] The eyeglass frame 10 is made of TR90 memory polymer material, with a frame width of 140mm and a temple length of 145mm, which fits the head shape of most adults.

[0091] The nematic liquid crystal lens 20 adopts a structure in which a nematic liquid crystal layer is sandwiched between two layers of 0.7mm thick ITO conductive glass. The liquid crystal layer is 5μm thick. The transparent electrode layer adopts a 16×16 dot matrix ITO electrode with a light transmittance ≥85%.

[0092] The integrated module 30 adopts an integrated packaging process, with an overall size of 45mm×8mm×6mm. It is embedded in the hollow cavity of the left temple and electrically connected to the camera 40 on the right temple and the nematic liquid crystal lens 20 in the frame via a flexible ribbon cable.

[0093] The internal sub-modules of the integrated module 30 adopt a stacked layout. The bottom layer is the power module 306, the middle layer is the main control module 305 and the drive module 301, and the top layer is the SIM card communication module 304, microphone 302 and speaker 303. The microphone 302 opening is located at the front of the left temple near the corner of the mouth, and the speaker 303 opening is located at the rear of the left temple near the ear canal opening.

[0094] The camera 40 uses a 2-megapixel CMOS sensor with a 60° field of view and a fixed focal length. It is mounted on the outer front end of the right temple and the lens surface is covered with a sapphire scratch-resistant lens to enable basic photo taking and video call functions.

[0095] Regarding circuit parameters:

[0096] The main controller 3051 uses a low-power STM32 microcontroller with an operating frequency of 80MHz;

[0097] The adjustable voltage unit 3011 uses the TPS61088 boost chip, with an output voltage range of 0-10V and an adjustment accuracy of 0.1V;

[0098] The electrode drive array 3012 uses the ADS7843 driver chip;

[0099] SIM card unit 3041 supports Nano-SIM cards;

[0100] The RF transceiver unit 3042 uses the EC200S-CN4GCat.1 module;

[0101] The audio codec unit 3043 uses the ES8311 low-power audio codec;

[0102] The rechargeable lithium battery unit 3061 has a capacity of 250mAh, and the charging management unit 3062 supports 5V / 0.5A charging via a Type-C interface;

[0103] The workflow is as follows:

[0104] Press and hold the power button on the left temple for 3 seconds. The power distribution management unit 3063 supplies power to each module. The main controller 3051 reads the system configuration parameters and the default diopter parameter (-2.00D) from the data storage unit 3052 and outputs the corresponding driving voltage adjustment signal to the adjustable voltage unit 3011. The electrode driving array 3012 outputs the driving voltage to the transparent electrode layer, which changes the molecular arrangement of the nematic liquid crystal layer and adjusts the lens diopter to -2.00D.

[0105] When a call comes in, the RF transceiver unit 3042 receives the call signal and transmits it to the main controller 3051. The main controller 3051 controls the audio codec unit 3043 to convert the digital voice signal into an analog signal, which is then played through the speaker 303. When the user answers the call by briefly pressing the power button, the microphone 302 collects the user's voice signal, which is then digitized and encoded by the audio codec unit 3043 and transmitted to the RF transceiver unit 3042, and then sent to the other party via the wireless network. After the call ends, the user briefly presses the power button to hang up the phone.

[0106] Press the power button twice in quick succession to enter the diopter adjustment mode. Each short press of the power button increases the diopter by 0.25D. Press and hold the power button for 1 second to decrease the diopter by 0.25D. After adjustment, if there is no operation for 5 seconds, the current diopter parameters will be automatically saved to the data storage unit 3052.

[0107] Pressing the power button three times consecutively will cause the camera 40 to take a picture and store it in the data storage unit 3052. During a call, pressing the power button three times consecutively will activate the video call function. The video data collected by the camera 40 will be processed by the main controller 3051 and then sent to the other party through the radio frequency transceiver unit 3042.

[0108] The remaining technical details in this embodiment are described above and will not be repeated here.

[0109] Example 2

[0110] This embodiment adds an automatic diopter adjustment function based on camera 40 to the existing embodiment 1. Specifically:

[0111] The main controller 3051 programs the object distance detection algorithm and the automatic diopter matching algorithm, while the data storage unit 3052 pre-stores the optimal diopter parameter table corresponding to different object distances. The camera 40 continuously captures scene images at a frame rate of 5fps, and the main controller 3051 detects the distance between the user and the object in real time through image feature extraction and depth calculation.

[0112] When the user's viewing distance is detected to be 30cm (reading scenario), the main controller 3051 automatically calls the reading mode diopter parameter (-3.00D) stored in the data storage unit 3052 and outputs the corresponding adjustment signal to the drive module 301 to adjust the lens diopter to -3.00D; when the user's viewing distance is detected to be more than 5m (distant viewing scenario), the main controller 3051 automatically calls the distant viewing mode diopter parameter (-2.00D) to adjust the lens diopter to -2.00D; when the user's viewing distance is detected to be between 30cm and 5m, the main controller 3051 calculates the corresponding optimal diopter parameter based on the distance value through linear interpolation and adjusts it in real time.

[0113] To avoid accidental triggering, the diopter adjustment will automatically pause when the user's head is rapidly turned or their eyes are closed for more than 1 second; the automatic adjustment function will be restored when the user maintains a stable visual state for more than 2 seconds. The user can switch between manual and automatic diopter adjustment modes by pressing the power button 4 times in succession.

[0114] Example 3

[0115] This embodiment adds a multi-user switching function based on face recognition using camera 40, specifically:

[0116] The face recognition algorithm is programmed into the main controller 3051, and the data storage unit 3052 can store up to 8 sets of facial feature information, corresponding refractive parameters, call configuration parameters and frequently used contact information of different users.

[0117] When used for the first time, the user presses and holds the power button for 5 seconds to enter the user registration mode. The camera 40 captures the user's face image, and the main controller 3051 extracts the face feature information and stores it in the data storage unit 3052. At the same time, the user can set the corresponding refractive power parameters and call configuration parameters.

[0118] In daily use, the camera 40 automatically captures facial images after powering on. The main controller 3051 compares the captured facial features with the feature information stored in the data storage unit 3052. If the comparison is successful, the corresponding refractive error parameters and call configuration parameters for the user are automatically loaded. If the comparison fails, the default user parameters are loaded.

[0119] Users can manually switch registered users by pressing the power button five times in quick succession; they can also delete user information stored in data storage unit 3052 by performing a delete operation.

[0120] In summary, the novel smart glasses disclosed in this invention have at least the following beneficial effects:

[0121] (1) It solves the core technical problem that existing smart glasses cannot simultaneously integrate electrically adjustable refractive power vision correction and independent voice call functions;

[0122] (2) By using a nematic liquid crystal lens in conjunction with a drive module, the electronically controlled dynamic adjustment of the refractive power of vision correction is realized, replacing the traditional fixed optical lens;

[0123] (3) Voice calls can be sent and received independently through the built-in SIM card communication module, so that smart glasses can complete communication without relying on a smartphone.

[0124] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
