In this chapter, we have discussed various sensors that are generally available to us from mobile market devices. We have discussed how to create a basic plugin in the major languages for the different platforms at our disposal, and we now have all of the basic knowledge we need to get started making AR applications and games with Unity. 

In the next chapter, we will take what we have learned so far and create a prototype project that will allow us to incorporate sound as the basis for an AR application.
