Augmented Reality for Android Application Development

Chapter 5. Same as Hollywood – Virtual on Physical Objects

In the previous chapter you learned about the basic building blocks for implementing GPS and sensor-based AR applications. If you tried the different examples we presented, you might have noticed that the feeling of getting digital objects in real space (registration) works but can become coarse and unstable. This is mainly due to the accuracy problems of the used sensors (GPS, accelerometer, and so on) found in smartphones or tablet devices, and the characteristics of these technologies (for example, gyroscope drifting, GPS reliance on satellite visibility, and other such technologies). In this chapter, we will introduce you to a more robust solution, with it being the second major approach ...
