With the rapid development of smart audio, mobile phones, TWS headsets, smart watches, wearable devices, smart speakers, smart screens, smart glasses, smart homes and other products are gradually integrating smart audio technology to provide smart interconnection and more convenient control methods.
The popularity of TWS headsets has earned a lot of hot spots for smart wearable devices, and the smart wearable market has ushered in a new round of development opportunities. Among them, smart glasses are generally considered by the industry to be another market hotspot after TWS headsets.
The current smart glasses market mainly combines smart audio with the form of glasses and configures an independent operating system for it, so that it has the functions of both, that is, it can be used for fashion decoration, and it has an open style. Audio experience. But this is only the beginning of the smart glasses direction of various manufacturers. With the continuous development of technology, smart glasses will gradually link with vision to realize the function of AR augmented reality and provide more abundant applications.
Although smart audio glasses are only the beginning of smart glasses, many manufacturers have begun to lay out the market, which can occupy an advantageous position in the future smart glasses competition. Among them, brands such as Huawei, BOSE, Amazon, and Aftershockz have launched iterative products. Brands such as Rapoo and Razer have also launched their first smart glasses products; and brands such as Apple, Facebook, and OPPO have also established smart glasses projects.

2. AR smart glasses
AR augmented reality is a technology that calculates the position and angle of the camera image in real time and adds the corresponding image. It is a new technology that “seamlessly” integrates real world information and virtual world information. Through computer and other science and technology, virtual information is applied to the real world. The real environment and virtual objects are superimposed on the same screen or space in real time, and they are perceived by the human senses, so as to achieve a sensory experience beyond reality.
Smart audio glasses are in the previous stage of AR glasses, first solving the problem of open stereo audio. And the stage of commercial portable AR smart glasses will truly change the interactive experience of electronic technology products. Application scenarios such as AR video calling, AR viewing, AR office, AR navigation, etc. will bring a brand-new experience with a sense of future technology.
At present, many brand manufacturers such as Apple, Huawei, Samsung, Microsoft, Facebook, OPPO and other AR smart glasses equipped with AR augmented reality technology are actively exploring. However, compared to smart audio glasses, due to technical difficulties and limitations in volume and weight, most of them are still in the R&D and concept stage, and cannot be truly portable and used like ordinary glasses.
Among them, Apple AR glasses have received the most attention from the market. As early as 2018, foreign media broke the news that a well-known analyst published a report predicting that Apple will release augmented reality glasses called “Apple Glasses” by 2021 at the latest. Recently, well-known analyst Ming-Chi Kuo predicts in the Apple MR/AR product blueprint forecast that Apple is expected to launch helmet-type products in 2022 and glasses-type products in 2025 at the earliest.
In the direction of AR device research and development, Apple has applied for dozens of software and hardware patents. At present, many of Apple’s technologies and functions are also regarded as paving the way for AR devices, such as AirPods’ spatial audio technology, iPhone / Apple Watch / HomePod UWB ultra-wideband chip on other devices, LiDAR lidar scanner of iPhone 12 Pro series and iPad Pro 2020, etc.
Samsung has also been in the exploration stage with AR smart glasses. Last year, it unveiled an AR glasses at the 2020 CES Global Consumer Electronics Show. It is matched with Samsung’s smart fitness program called GEMS, which can display virtual coaches through AR glasses. Conduct simultaneous teaching.
Recently, two promotional videos of Samsung AR smart glasses were exposed. The videos showed some of the functions of Samsung Glasses Lite augmented reality glasses, including projection screen viewing, games, office, and interconnection with mobile phones, drones and other devices. Acting as a display screen; the other video shows the future application scenarios of Samsung AR glasses. Reality and virtual images are combined to realize functions such as virtual reality scenes and virtual video calls.
And Facebook also broke out to the outside world in 2020 that it is developing VR virtual reality glasses, which are very different from the bulky appearance of current VR glasses and resemble sunglasses on the market. According to reports, this spectacle lens is less than 9 mm thick and uses holographic optics (holographic optics) and other technologies, and said that the current work is only in the pure research stage.
In the domestic market, OPPO launched the second-generation AR glasses concept product OPPO AR Glass 2021 at the Future Technology Conference 2020. It is already very light in appearance design and can be used by connecting to a mobile phone. Using Birdbath optical technology, it can provide a viewing experience similar to watching a 90-inch giant screen from 3 meters away.
And it supports functions such as voice interaction, gesture control, and spatial positioning. Gesture control can detect and track both hands in milliseconds through a set of binocular fisheye cameras. When wearing AR glasses, users can perform gesture interactions such as tapping menus, pushing open and zooming in objects; spatial positioning uses a ToF lens, binocular fisheye camera and IMU to form a spatial positioning system to achieve centimeter level, 1 Positioning accuracy within.
The current smart glasses market is mainly based on smart audio glasses. After several years of development, the appearance is not much different from ordinary sunglasses, and it has both the functions of glasses and music playback, a sense of fashion and a sense of future technology. It is also stronger. And the open stereo audio provides users with a novel listening experience, liberates both ears, and avoids ear pain caused by long-term wearing of in-ear headphones.
However, the current smart audio glasses are only the beginning of smart glasses. With the continuous development of technology, future smart glasses products will be equipped with more functions and gradually become more complete. And with the application of AR augmented reality technology, the combination of visual effects and auditory experience, smart glasses will undergo earth-shaking changes, providing users with a new interactive experience. At that time, smart glasses may become the next competition place for Internet giants, mobile phone manufacturers, and audio manufacturers.
