On February 7th, 20 1 and 20 19, the World Intellectual Property Organization (WIPO) exposed a Huawei patent of "spectacle frame", describing a relatively economical AR head-mounted display device. Different from the smart glasses currently on the market, Huawei's smart glasses realize the functions of smart glasses such as AR by combining a specific smart watch with a spectacle frame, and the spectacle frame itself is not equipped with a camera, display screen or microphone.
2. After the combination of the two, the camera on the smart watch can be turned outwards to record user activities, AR, etc. In addition, special adapters and mirrors are used in the glasses frame so that users can project the contents displayed by the watch onto the glasses.
