[0052] Figure 1 FIG. 1 is a schematic diagram showing a communication system 100 according to an embodiment of the present application. For example, the communication system 100 can be applied in the field of virtual reality (VR) or augmented reality (AR), but is not limited thereto. As shown in FIG. 1, the communication system 100 includes at least a first contact lens element 110 and a second contact lens element 120. Figure 1

[0053] In some embodiments, the first contact lens element 110 and the second contact lens element 120 can operate according to a master-slave control mechanism, in which the second contact lens element 120 can be directly or indirectly controlled by the first contact lens element 110. That is, the first contact lens element 110 can be regarded as a master element, and the second contact lens element 120 can be regarded as a slave element.

[0054] ​The first contact lens element 110 includes an image capturer 111, a human body communication (HBC) module 112, and a processor 113. For example, the image capturer 111 can be implemented by a camera element. The image capturer 111 can capture a first image data DM1. The processor 113 is coupled to the image capturer 111 and the HBC module 112.

[0055] The second contact lens element 120 includes a second image capturer 121 and a second HBC module 122. For example, the second image capturer 121 can be implemented by another camera element. The second image capturer 121 can capture a second image data DM2. The second HBC module 122 is coupled to the second image capturer 121. It must be understood that although not shown in the figure, each of the first contact lens element 110 and the second contact lens element 120 can further include other elements, such as a transmission line, a signal source, an antenna element, an electrode, a battery, or (and) a power supply module. Figure 1

[0056] The first contact lens element 110 and the second contact lens element 120 can communicate through the first HBC module 112 and the second HBC module 122. The second HBC module 122 can transmit the second image data DM2 to the first HBC module 112. Then, the processor 113 can generate a viewing angle differential data DE according to the first image data DM1 and the second image data DM2. For example, the first image data DM1 can correspond to a left eye image of a user, and the second image data DM2 can correspond to a right eye image of the user, but not limited thereto. In detail, the processor 113 can compare the first image data DM1 and the second image data DM2 with each other, and then determine the viewing angle differential data DE according to a difference value between the two.

[0057] ​According to actual measurement results, since the first contact lens element 110 and the second contact lens element 120 are connected through a human body communication mechanism, various data are transmitted through the human body as a transmission medium, so that the overall communication quality and data accuracy can be greatly improved. In addition, the generation of the perspective difference data DE also helps to improve the subsequent data compression and corresponding transmission efficiency.

[0058] The following embodiments will introduce various different configurations and detailed structural features of the communication system 100. It must be understood that these drawings and descriptions are only examples and are not intended to limit the present application.

[0059] Figure 2 is a schematic diagram showing a communication system 200 according to an embodiment of the present application. Figure 2 and Figure 1 Similarly, in the embodiment of Figure 2 , the communication system 200 includes a first contact lens element 210, a second contact lens element 220, and a computing device 230, wherein the second contact lens element 220 can be directly or indirectly controlled by the first contact lens element 210. For example, the computing device 230 can be implemented through a mobile device, such as a smart phone, a tablet computer, or a notebook computer.

[0060] The first contact lens element 210 includes a first image capture device 211, a first human body communication module 212, a processor 213, a first wireless communication module 214, and a first display 215. The first image capture device 211 can capture a first image data DM1. The processor 213 is coupled to the first image capture device 211, the first human body communication module 212, and the first wireless communication module 214. For example, the first wireless communication module 214 can be a Bluetooth module or a Wi-Fi module, but is not limited thereto.

[0061] The second contact lens element 220 includes a second image capture device 221, a second human body communication module 222, and a second display 225. The second image capture device 221 can capture a second image data DM2. The second human body communication module 222 is coupled to the second image capture device 221 and the second display 225.

[0062] The first contact lens element 210 and the second contact lens element 220 can communicate through the first human communication module 212 and the second human communication module 222. In some embodiments, when the first contact lens element 210 communicates with the second contact lens element 220, both the first human communication module 212 and the second human communication module 222 can use a first human communication operating frequency band FB1. For example, the first human communication operating frequency band FB1 can be between 60 MHz and 100 MHz, but is not limited thereto. The second human communication module 222 can transmit the second image data DM2 to the first human communication module 212. Then, the processor 213 can generate a perspective difference data DE according to the first image data DM1 and the second image data DM2. Then, the processor 213 can transmit the first image data DM1 and the perspective difference data DE to the computing device 230 using the first human communication module 212.

[0063] Generally, the computing device 230 can receive and process the first image data DM1 and the perspective difference data DE. It must be understood that because the computing device 230 does not need to receive the second image data DM2, the overall data transmission of the communication system 200 can be further reduced. However, the computing device 230 can still estimate the second image data DM2 according to the first image data DM1 and the perspective difference data DE. In detail, the computing device 230 includes a third human communication module 232, an image processing module 233, and a second wireless communication module 234. The image processing module 233 is coupled to the third human communication module 232 and the second wireless communication module 234. For example, the second wireless communication module 234 can be another Bluetooth module or another Wi-Fi module, but is not limited thereto.

[0064] The third human communication module 232 can receive the first image data DM1 and the perspective difference data DE from the first human communication module 212. In some embodiments, when the first contact lens element 210 communicates with the computing device 230, both the first human communication module 212 and the third human communication module 232 can use a second human communication operating frequency band FB2, which can be different from the first human communication operating frequency band FB1 described above. For example, the second human communication operating frequency band FB2 can be between 10 MHz and 50 MHz, but is not limited thereto. In this design, even if the first human communication module 212 is shared, the data transmission of the second human communication operating frequency band FB2 is not easily interfered with the data transmission of the first human communication operating frequency band FB1 described above. In other embodiments, the processor 213 can also use the first wireless communication module 214 to transmit the first image data DM1 and the perspective difference data DE to the second wireless communication module 234.

[0065] The image processing module 233 can generate a display information IM according to the first image data DM1 and the perspective difference data DE. For example, the display information IM can include: distance (Distance), object identification (Object Identification), object tracking (Object Tracking), or (and) general augmented reality related information, but not limited thereto. Then, the image processing module 233 can use the second wireless communication module 234 to transmit the display information IM to the first wireless communication module 214.

[0066] In the first contact lens element 210, the first display 215 can obtain the display information IM from the first wireless communication module 214. The first display 215 can further display a target picture TG according to the display information IM. Then, the processor 213 can use the first human communication module 212 to transmit the display information IM to the second contact lens element 220.

[0067] In the second contact lens element 220, the second human communication module 222 can receive the display information IM from the first human communication module 212. The second display 225 can obtain the display information IM from the second human communication module 222, wherein the second display 225 can further display the aforementioned target picture TG according to the display information IM. In other words, the first display 215 and the second display 225 can perform a synchronized display program to improve the actual visual experience of the user. It must be noted that because the second contact lens element 220 is substantially controlled by the first contact lens element 210, the computing resource of the communication system 200 will be more conservatively used, thereby reducing the overall power consumption.

[0068] Figure 3 is a flowchart showing a communication method according to an embodiment of the present application. First, in step S310, a first contact lens element and a second contact lens element are provided, wherein the first contact lens element includes a first image grabber, a first human communication module, and a processor, and the second contact lens element includes a second image grabber and a second human communication module. In step S320, a first image data is grabbed by the first image grabber. In step S330, a second image data is grabbed by the second image grabber. In step S340, the second image data is transmitted to the first human communication module by the second human communication module. Finally, in step S350, a perspective difference data is generated by the processor according to the first image data and the second image data. It must be understood that the above steps do not need to be performed in sequence, and Figure 1 、 2 each feature of the embodiment of Figure 3 the communication method can be applied to the communication method.

[0069] The present invention proposes a novel communication system and method. Compared with conventional designs, the present invention has advantages such as improved communication quality, increased transmission efficiency, reduced computing resources, and reduced signal interference, making it suitable for application in a variety of devices.
