In this chapter, we introduced the foundational background of AR. We've presented some of the main concepts of AR, such as sensory augmentation, dedicated display technology, real-time spatial registration of physical and digital information, and interaction with the content.
We've also presented computer vision-based and sensor-based AR systems, the two major trends of architecture on mobile devices. The basic software architecture blocks of an AR application have also been described and will be used as a guide for the remaining presentation of this book. By now, you should have installed the third-party tools used in the coming chapters. In the next chapter, you will get started with viewing the virtual world and implementing camera access with JME.
