Augmented reality (AR) has applications in many areas including sports, ecommerce, education, entertainment, and the military. AR uses mobile devices and sensors to overlay digital information and graphics onto the real world. Early examples of AR date back to the 1970s and 1980s but the technology is now more widely used. Popular AR apps allow users to play games, view product information and translations, and get directions overlaid on real-time camera views of locations. Developers have a variety of toolkits for creating AR experiences across Android, iOS, and Windows platforms. The goal of AR is to automate tasks and facilitate collaboration through integrated technologies that solve problems effectively.
