At the end of March, Xiaomi launched its new smart glasses - MIJIA smart audio glasses, which attracted widespread attention. Previously, companies such as Huawei and OPPO have also released smart eyewear products. International Data Corporation predicts that global shipments of smart glasses will continue to rise, reaching 123 million units by 2025. However, some people believe that smart glasses are still limited to entertainment in terms of product functionality. So, in the constantly growing intelligent ecosystem, what role does smart glasses play? What scenarios may be applied in the future? What is the development trend of smart glasses? Playing an important role in the intelligent ecosystem, as a product of a new wave of technology, smart glasses are not only a digital upgrade of traditional glasses, but also a deep integration of visual experience and intelligent concepts. With the continuous progress of technology and the gradual maturity of the market, smart glasses are expected to play a more important role in the intelligent ecosystem. Smart glasses are carriers of new ways of interaction. It integrates hardware such as display screens, sensors, cameras, speakers, and has an independent operating system. In addition to traditional interaction methods such as voice and touch, users can also control it through other means, such as eye movement. This human-computer interaction method that integrates virtual and real has enormous potential in multiple fields such as business, office, and entertainment, and is expected to bring users a brand new experience that is different from the past. Smart glasses are an important part of the smart ecosystem. Currently, with the accelerated integration of artificial intelligence into various industries, wearable smart devices such as smart helmets and smartwatches are constantly emerging. The maturity of smart glasses technology is relatively high, gradually becoming a popular product in the wearable smart device field. In the future, smart glasses will leverage their lightweight, portability, and high user stickiness to complement and collaborate with smart devices such as smartphones and smart homes, leveraging their advantages of realism and strong on-site experience. This will provide users with a more comprehensive and intelligent experience and help build a complete intelligent ecosystem. It is expected to be applied in new application scenarios such as sports, entertainment, and work. Due to its unique advantages, smart glasses may unlock more new application scenarios. Firstly, new sports scenes. Smart glasses can display information in real-time more directly, allowing users to obtain new messages when it is inconvenient to use smart terminal devices. For example, with the assistance of other wearable smart devices such as smart wristbands, smart glasses can allow users who are exercising to see their exercise data and physical condition information in real time. Secondly, new cultural and entertainment scenes. Smart glasses are concrete products that align with the concept of virtual and real fusion. They can achieve real-time holographic display and provide users with an immersive experience more conveniently. This makes smart glasses an ideal auxiliary tool for VR games, watching movies, live streaming and other entertainment activities. Thirdly, exchange new scenarios. Smart glasses can speak in first person
