In this chapter, we showed you how to go beyond the standard AR applications by using multi-targets or cloud recognition for computer-vision-based AR. We also showed you how you can improve the tracking performance for your image targets. In addition, we introduced you to some advanced rendering techniques for your AR applications. Finally, we also showed you some novel interaction techniques that you can use to create great AR experiences. This chapter concludes your introduction to the world of Augmented Reality development for Android. We hope you are ready to progress onto new levels of AR application development.
