AR display, also known as augmented reality display, is a technology that superimposes digital information, such as images, videos, or 3D models, onto the user's view of the real world. This technology typically involves the use of special glasses, headsets, or mobile devices that overlay digital content onto the user's physical environment in real-time. AR display technology has a wide range of applications, including gaming, education, training, healthcare, and more. It allows users to interact with digital content in a more immersive and interactive way, enhancing their overall experience and understanding of the information being presented. Researchers in the field of AR display are continuously exploring new ways to improve the technology, such as enhancing the accuracy of object recognition, improving display quality, and refining user interaction methods. Overall, AR display technology has the potential to revolutionize how we perceive and interact with the world around us.
