Kinect v2 Examples with MS-SDK and Nuitrack SDK

This is a set of Kinect-v2 (aka ‘Kinect for Xbox One’) examples that use several major scripts, grouped in one folder. The package contains over thirty demo scenes.

Apart of the Kinect-v2 and v1 sensors, the K2-package supports Intel’s RealSense D400-series, as well as Orbbec Astra & Astra-Pro sensors via the Nuitrack body tracking SDK. Please mind that Nuitrack SDK is in early stage, and issues are possible.

The avatar-demo scenes show how to utilize Kinect-controlled avatars in your scenes, gesture-demos – how to use programmatic or visual gestures, fitting room demos – how to create your own dressing room, overlay demos – how to overlay body parts with virtual objects, etc. You can find short descriptions of all demo-scenes in the K2-asset online documentation.

This package works with Kinect-v2, Kinect-v1 (aka Kinect for Xbox One & Kinect for Xbox 360), Intel RealSense D415 & D435, Orbbec Astra & Astra-Pro, and other Nuitrack supported sensors, as well. It can be used in all versions of Unity – Free, Plus & Pro.

How to Run the Demo Scenes:
1. (Kinect-v2) Download and install Kinect for Windows SDK v2.0. The download link is below.
2. (Kinect-v2) If you want to use Kinect speech recognition, download and install the Speech Platform Runtime, as well as EN-US plus the other needed language packs. The download links are below.

4. Import this package into new Unity project.
5. Open ‘File / Build settings’ and switch to ‘PC, Mac & Linux Standalone’, Target platform: ‘Windows’.

One request:
My only request is NOT to share this package or its demo scenes in source form with others, or as part of public repositories, without my explicit consent.

Troubleshooting:
* If you get compilation errors like “Type `System.IO.FileInfo’ does not contain a definition for `Length’”, you need to set the build platform to ‘Windows standalone’. For more information look at this tip.
* If the Unity editor crashes, when you start demo-scenes with face-tracking components, look at this workaround tip.
* If the demo scene reports errors or remains in ‘Waiting for users’-state, make sure you have installed Kinect SDK 2.0, as well as the other needed components, and check if the sensor is connected.
* For other known issues, please look here.
