This chapter shows you how to use media controls such as Image, CaptureElement, and MediaElement to render video and audio streams, including acquiring a video stream from your headset’s world-facing camera. You will also learn how to detect human faces in the acquired images (see Figure 5-1). Finally, you will explore UWP speech-synthesis and speech-recognition engines and learn how to use them to support hands-free interaction between the user and the app on the Mixed Reality device. Several classes developed in this chapter will be stored in the reusable MixedReality.Common class library; you will use them to build more complex examples in next chapter.

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
