Augmented Reality: A Comprehensive Review

Augmented Reality (AR) aims to modify the perception of real-world images by overlaying digital data on them. A novel mechanic, it is an enlightening and engaging mechanic that constantly strives for new techniques in every sphere. The real world can be augmented with information in real-time. AR aims to accept the outdoors and come up with a novel and efficient model in all application areas. A wide array of fields are displaying real-time computer-generated content, such as education, medicine, robotics, manufacturing, and entertainment. Augmented reality is considered a subtype of mixed reality, and it is treated as a distortion of virtual reality. The article emphasizes the novel digital technology that has emerged after the success of Virtual Reality, which has a wide range of applications in the digital age. There are fundamental requirements to understand AR, such as the nature of technology, architecture, the devices required, types of AR, benefits, limitations, and differences with VR, which are discussed in a very simplified way in this article. As well as a year-by-year tabular overview of the research papers that have been published in the journal on augmented reality-based applications, this article aims to provide a comprehensive overview of augmented reality-based applications. It is hard to find a field that does not make use of the amazing features of AR. This article concludes with a discussion, conclusion, and future directions for AR.
