The Mixed Reality Toolkit is a collection of scripts and components intended to accelerate development of applications targeting Microsoft HoloLens and Windows Mixed Reality headsets. The project is aimed at reducing barriers to entry to create mixed reality applications and contribute back to the community as we all grow.
MixedRealityToolkit-Unity uses code from the base MixedRealityToolkit and makes it easier to consume in Unity.
Learn more about Windows Mixed Reality here.
Note: The latest release should work for both HoloLens and Windows Mixed Reality development.

The Mixed Reality Toolkit for Unity includes many API's to accelerate the development of Mixed Reality projects for both HoloLens and the newer Immersive Headsets (IHMD)
 Input |
 Sharing |
 Spatial Mapping |
|---|---|---|
| Scripts that leverage inputs such as gaze, gesture, voice and motion controllers. Includes the Mixed Reality camera prefabs. | Sharing library enables collaboration across multiple devices. | Scripts that allow applications to bring the real world into the digital using HoloLens. |
 Spatial Sound |
 UX Controls |
 Utilities |
| Scripts to help plug spatial audio into your application. | Building blocks for creating good UX in your application like common controls. | Common helpers and tools that you can leverage in your application. |
 Spatial Understanding |
 Build |
 Boundary |
| Tailor experiences based on room semantics like couch, wall etc. | Build and deploy automation window for Unity Editor. | Scripts that help with rendering the floor and boundaries for Immersive Devices. |
 Windows 10 FCU |
 Unity 3D |
 Visual Studio 2017 |
 Simulator (optional) |
|---|---|---|---|
| To develop apps for mixed reality headsets, you need the Windows 10 Fall Creators Update | The Unity 3D engine provides support for building mixed reality projects in Windows 10 | Visual Studio is used for code editing, deploying and building UWP app packages | The Emulators allow you test your app without the device in a simulated environment |
To get up and going as quickly as possible, here are some guides to help you get started building Mixed Reality Projects
 Quick start |

 Fall Creators Update |
|---|---|---|
| Please go over the Getting started guide to learn more about getting off the ground quickly. | Please go over the Contributing guidelines to learn more about the process and thinking. | Check out the recent updates for Windows Mixed reality in the Fall Creators update |
The MRTK includes many great samples and starter scenes to demonstrate the uses of the MRTK API, these include:
 Motion Controller tests |
 Input manager tests |
 Grab Mechanics demo |
|---|---|---|
| Motion controller test scene demonstrating controller input events | Several gaze interaction demos such as popups, buttons and more | Examples of direct manipulation with Motion Controllers (IHMD Only) |
 Interactable Objects |
 Object Collection |
 App Bar and Bounding Box |
| Example of modular and extensible interactable objects with visual states, including Holographic button | Object collection helps you lay out an array of objects in a three-dimensional shape | [Coming Soon] Standard UI for move/rotate/scale 3D objects |
 Keyboard input sample |
 Interactive button demos |
 Scene occlusion demo |
| A sample virtual keyboard, similar to system keyboard in Windows Mixed Reality shell | Example UI buttons and controls for use in Mixed Reality | Scene construction demo on how to make occluded windows |
Check out the Examples folder for more details.
External\How To docs folder is meant to help everyone with migrating forward or any simple doubts they might have about the process. Please feel free to grow all these sections. We can't wait to see your additions!
