Follow along easily and get a great start to building your own apps. You don't even need a physical HoloLens device! In this course, HoloLens Development Fundamentals, you're going to be building a demo app that showcases the five main pillars of mixed reality experiences for HoloLens. First, you'll cover how to use gaze, gestures, and spatial mapping to manipulate a full 3D experience with natural interaction. Next, you'll learn how to create actions that handle basic or complex gestures, such as tap, navigate, or manipulate. Then, you'll discover how to design both voice commands and audio, and then implement them for your users to use. Finally, you'll go through how to take advantage of the holographic framework to implement both voice commands and spatial audio, with little effort, and bring your HoloLens app to life. By the end of this course, you'll have an understanding of what mixed reality apps are and how they are put together.
