# VRArmIK

VRArmIK brings arms into VR without any additional tracking devices. 

Using head and hand positions, the shoulders and arms are estimated to create realistic arm movements.

[See the Video on Youtube](https://youtu.be/dHgH6Xsi3JQ)

# Features

* VR Tracking to Wrist and Neck estimations (currently only optimized for Oculus Touch)

* Estimates shoulder position and orientation 

  * 360° movement

  * crouching 

  * distinct shoulder rotations when stretching the arms to their limits

  * arm dislocation when the distance between shoulders and controllers is larger than the virtual arm

* Simple Arm IK Solver which connects shoulders with hand target positions

* Complex Elbow Angle calculations

  * many variable to optimize the IK for different use cases

  * prevents unrealistic hand rotations

# How To Use

1. Download package from [Unity Asset Store](http://u3d.as/1d07)

2. Add PoseManager and Avatar Prefab into your scene

3. Run

Take a look at the Demo scene to see a working demo.

# Tips & Tricks

1. If the code does not compile, make sure that the Scripting Runtime is set to .NET 4.6 instead of 3.5. [Unity Manual](https://docs.unity3d.com/Manual/ScriptingRuntimeUpgrade.html)

2. If the shoulders are always (or never) facing downwards, try using Unity's "Camera OFfset" with tracking mode set to "Floor" and camera Y offset set to 0. If you do so, you also need to follow the next step:

3. If the avatar is a couple of meters below your head, try setting the "Vr System Offset Height" in the PoseManager to 0.
