This chapter provided you with an inside look at the different components of the HoloLens device. You saw the major components of the device such as camera, sensors, lenses, speakers, and a set of processing units. The camera and sensors ensure the capturing and projecting of holograms, which is of prime importance for the functioning of the device; the speakers, on other hand, ensure the floating and surrounding audio that give a mixed experience along with the 3D view objects. It is also worth mentioning how different sets of processing units come together and process high volumes of data to produce an immersive experience. It would not be wrong to say that it is this combination of technological innovations that makes the HoloLens the awe-inspiring device that it is.

You have gone through the different possibilities of applications that can be developed using HoloLens. In the next chapter, we will jump-start building projects from scratch. Through these projects, you will learn not just about 3D application development for HoloLens, but will also learn about integration scenarios, which will be one of the core requirements for enterprises. You will learn to integrate with Azure services from within the HoloLens application, and dynamically consume data from cloud and change the user experience in real time.
