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

• 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

1. Download package from Unity Asset Store
2. Add PoseManager and Avatar Prefab into your scene
3. Run

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

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
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.
