00:03With Microsoft HoloLens you can create mixed reality apps. Apps that combine
00:09the real world with a virtual holographic world. Here are the five
00:14building blocks you need to start building on the Windows holographic
00:17platform. Gaze is the first form of user interaction on HoloLens. It tracks where
00:23a person's head is turned to target items in the environment. To interact
00:28with those items you use gestures. The sensors on HoloLens read specific
00:32movements of your hands. Voice allows you to speak commands to control action in
00:38your app. Recognizing the world around you is done through spatial mapping. It
00:45creates a mesh of a room allowing your holograms to interact with the surfaces
00:49that it finds. You can use this information to set holograms on a table,
00:53stick them on a wall, or interact with the furniture in your room. Finally there
00:59is spatial sound. 3D sound makes the experience more immersive. Sound from
01:05holograms is realistic and can come from all directions. To build apps on the
01:11Windows holographic platform you can use familiar tools. Visual Studio with the
01:16Windows 10 SDK, Unity, a new emulator for testing out your apps, and the Windows
01:24Dev Center for Docs and Tutorials. Everything is built into the Universal
01:29Windows platform. This means all Universal Windows apps can be made into holograms
01:34and all holograms are Universal Windows apps. This is just a quick overview of the
01:41unique aspects of the HoloLens development environment. Imagine your app beyond the
01:47limitations of a screen in the creative new world of HoloLens.
