Summary

In this chapter, we've introduced you to three interaction techniques, suitable for a wide variety of AR applications. Picking allows you to select 3D objects by touching the screen, just like you would in 2D selection. Proximity-based camera techniques allow you to experiment with the distance and orientation of your device to trigger application events. Finally, we've showed you a simple example of a 3D gesture detection method to add even more interaction possibilities into your application. These techniques should serve as building blocks for you to create your own interaction methods, targeted to your specific application scenario. In the final chapter, we will introduce some advanced techniques and further reading to help you get the best out of your Augmented Reality applications.
