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.

Apple

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

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.

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.

3.Conclusion

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.
