In this chapter we were introduced to the meaning and possibilities of augmented reality. It is a very exciting field that has been briefly introduced in this chapter. We have been introduced to the many forms of augmented reality and how it manifested themselves in the hand of the users in the form of smartphones. We know also understand how powerful AR is at delivering immersive experience for users.

We were introduced to Vuforia, the free AR SDK by Qualcomm. We understand how powerful it can be in improving the flow of creating AR apps for users. Having it handle the technicalities of AR and allowing us to focus on making a better experience. We know the many tracking techniques that Vuforia offers and how different of an experience each can deliver. This should allow us to better utilize them in the future.

Unity was introduced to us, we have a vague idea of how powerful that engine is or how it can enable us as developers to forge AR experience as creatively as we want them. In the book, we will further explore the surface of Unity's power. While we won't be able to go through everything that is Unity in this book, we will see how simple knowledge in a few components can create impressive AR apps.

In the next chapter, we will go through the process of setting up our environment to start creating AR apps. We will set up both Unity and Vuforia to better understand how they both work together. We will also deploy Vuforia sample apps on device to test how a final app looks like.
