Status Quo of augmented reality (Overview)

It's so tired. Busy all day. This kind of work is about to crash.

Augmented reality (AR) is a technology that integrates virtual objects or other information generated by computers with the real environment seen by users. It can combine virtual reality with real-time interaction, 3D registration features. Unlike traditional virtual reality (VR), augmented reality provides users with a composite visual effect based on the existing real world, when a user moves in a real scenario, the virtual object changes accordingly, so that the virtual object can be perfectly combined with the real environment. With its powerful spatial data analysis and processing capabilities, ar technology has been widely used in medicine, industrial assembly and training, robot path design, film and entertainment, aviation design, military and other fields.

Ivan Sutherland, a pioneer in computer graphics technology, and his students at Harvard University and Utah State University jointly developed the earliest AR system model, which proposed ultimate display) a word used to describe the display system of computer graphics. It can track the person's head to update the display, so that the user is like in virtual reality, he is considered a pioneer in modern virtual reality. Since then, from 1970s to 1980s, a small number of researchers have been engaged in Ar System Research at the armland laboratory at the U.S. Air Force Base, the NASA Ames Research Center, and the University of North Carolina. By 1990s, Boeing researchers had developed a pilot AR system to assist workers in cabling. In the past decade, the sharp decrease in hardware prices has lowered the price of AR system laboratory equipment to an acceptable level, leading to the climax of a new round of AR system research. In 1994, Professor M. Green from Albert University in Canada re-conducted research in this direction and received high attention from all parties. Now the University of wisconsion-Madison, Washington State University, briham young university, SUNY at Buffalo, and University of clemenson have all started research in this direction. Since 1998, researchers from the AR system around the world will hold a meeting every year to exchange the latest research results.

Compared with Immersive Virtual Reality, augmented reality is not only widely used but also safer. Because the Augmented Reality system allows users to still see real scenarios while viewing virtual objects. Researchers in this field began to gather at a series of annual international seminars and work conferences related to augmented reality, such, international augmented reality working conferences, international Augmented Reality Seminars, and International mixed and augmented reality conferences have greatly promoted the research and development of augmented reality! In recent years, with the increasing computing capability of mobile devices and attention to the grid computing environment, research on outdoor Augmented Reality systems and support for Distributed Collaborative operations Augmented Reality systems has increased significantly.
