Motion Sickness Teleport System

[MiPa12]

Describe the problem

Hi, with the current teleport system provided by the mixed reality toolkit, I get motion sickness when moving back or turning.

Describe the solution you'd like

Similar to the solution provided in the mixed reality portal (black shadows appear on the edge when turning or moving back):

You should check out @FejZa new Locomotion system for the #XRTK which provides several "out of the box" teleport systems and an extensible framework for adding more https://github.com/XRTK/com.xrtk.core/tree/development/XRTK-Core/Packages/com.xrtk.core/Runtime/Services/LocomotionSystem

You can either use it in the xrtk, or with a few modifications, use it in the MRTK as they are based on the same core (just make sure to retain the OpenSource License with the feature)

It is on our v3 roadmap to rethink how our teleportation / locomotion system works.

Here are some locomotion methods that might be useful to look to get ideas of what kind of method to implement for VR.

XinReality - Locomotion

A database of Locomotion techniques, similar to Locomotion Vault, but there are some links to source code of the locomotion techniques.
