Mixed Reality blends people, places and things across a full spectrum ranging from the real-world to digital virtual worlds. This session is your introduction to building 3D applications and games for Windows Mixed Reality using C#, Visual Studio and Unity. We’ll start with a quick recap of Mixed Reality, the HoloLens device, immersive headsets and the Universal Windows Platform (UWP), and talk about interacting with holograms using gaze, gestures and voice. Next, we’ll dive into building 3D apps for Windows Mixed Reality in Unity with C#, using the Mixed Reality Toolkit for Unity, exporting our project to Visual Studio and running it on either a HoloLens device, an immersive Mixed Reality headset or the HoloLens Emulator. Science fiction becomes science fact, and Unity & UWP developers are at the front of this revolution. Come learn how to get started and build your journey into a world of holograms you create.

5. Defining Mixed Reality

7. The state of things as they “actually
exist” through our human senses
without any technology.
Artificially created sensory experiences of
people, environments and objects, which can
include sight, touch, hearing, and smell.

23. What is HoloLens?
Holograms enhance the
real world
Microsoft HoloLens is the first, fully untethered holographic computer
that redefines personal computing and empowers you in new ways.
New ways to connect,
create, and explore
A more natural way to
interact
Advanced technology
from Microsoft

26. Windows Mixed Reality
Universal Windows Platform

27. One platform. Multiple Windows devices.
One Universal Windows Platform
Windows Mixed Reality is built into the Windows SDK that
developers already use today.
The Universal Windows Platform makes it easy to build an
application that scales from HoloLens to other mixed reality
headsets.
• Target windows.holographic for holographic headsets
• Target windows.desktop for immersive headsets
Windows is the only platform unifying the mixed reality
ecosystem, providing inside-out tracking for headsets, a
single platform and standardized inputs for developers, and
a consistent interface with a single store for customers.​

42. Galaxy Explorer
Open source application available in the store. The idea was voted by the
community and originally built for HoloLens. It now supports all mixed reality
devices, and is a useful end-to-end demonstration of how to build a Unity app for
Windows Mixed Reality.
Mixed Reality Toolkit
Library with many component that make it easier to build mixed reality apps,
including plug-ins for Unity. Some of the more popular components are the
sharing services for multiplayer mixed reality apps and spectator view.
Academy Tutorial Apps
The tutorials are great starting points for your app, and they improve with
community contributions too.
