Augmented reality (AR) technology is a cutting-edge innovation that seamlessly integrates real-world information with virtual elements. It enables users to experience sensory details—such as sight, sound, touch, and even taste—that are typically difficult to encounter in specific real-world settings. Through advanced computer technologies, these virtual elements are simulated and overlaid onto the real world, creating an enhanced perception of reality. The real environment and virtual objects are combined in real-time within the same visual space, offering an immersive and interactive experience.
AR not only displays real-world information but also overlays virtual data, allowing both types of information to complement and merge together. In visual AR applications, users can use head-mounted displays to combine the physical world with computer-generated graphics, enhancing their perception of the surrounding environment. This technology encompasses various innovations such as multimedia, 3D modeling, real-time video display, multi-sensor fusion, real-time tracking, and scene integration. Unlike traditional human perception, AR provides unique informational experiences that expand our understanding of the world.
One of the key features of AR systems is the integration of real and virtual information, real-time interactivity, and the ability to place virtual objects in a three-dimensional spatial context. AR has found wide application across multiple sectors including military, healthcare, construction, education, engineering, entertainment, and more. Its versatility allows it to enhance real-world environments by adding informative and engaging digital layers.
In the medical field, AR helps doctors locate surgical sites more accurately. In the military, it supports real-time geographic data and location identification. For cultural heritage, AR can reconstruct historical monuments, allowing visitors to explore virtual reconstructions of damaged parts. In industrial maintenance, it provides real-time technical support through augmented displays. In video communication, AR adds fun elements like virtual accessories during calls. In sports broadcasting, it enhances viewer engagement by overlaying relevant data. In gaming, AR games allow players worldwide to interact in shared real-world spaces. In tourism, it delivers contextual information about exhibits and locations. In urban planning, it projects future development scenarios into current environments.
Professor Wang Yongtian from Beijing Institute of Technology is a leading figure in AR research in China. The first AR application for everyday use was XINGWIKI, a free app released on Apple’s AppStore. As technology evolves, people aim to access consistent media and information across devices—from PCs to mobile phones, projectors to head-mounted displays. The future interface will extend beyond small screens, enabling users to interact naturally with information in larger, more flexible environments.
Virtual Reality (VR) and Augmented Reality (AR) have evolved significantly since their inception. VR was first conceptualized in 1965 by Ivan Sutherland, who introduced the idea of interactive graphic displays and force feedback devices. AR emerged from research on head-mounted displays, aiming to provide additional information over real-world environments. Over the years, both technologies have seen advancements in hardware, software, and integration with other fields like AI and big data.
The application of VR and AR in education has opened new possibilities. These technologies offer immersive learning experiences, making complex concepts tangible and interactive. They stimulate student interest, facilitate cross-disciplinary learning, and support personalized education. From head-mounted devices to handheld apps, each tool brings unique benefits to different educational contexts.
Despite the potential, challenges remain. Issues such as motion sickness from VR devices, limited educational resources, high costs, and technical constraints hinder widespread adoption. However, ongoing developments in hardware, software, and AI promise to overcome these barriers, paving the way for broader implementation in schools and classrooms.
Looking ahead, VR and AR will continue to transform teaching methods, improve educational efficiency, and foster innovation. As these technologies mature, they will play a crucial role in shaping the future of education, making learning more engaging, accessible, and impactful for students around the world.
