recorded by Bumble of RIPmotion by Ryan Sullivan
By walking and running in place with the controller facing directly ahead, this method mimics the movement of walking and running allowing users to navigate environments naturally with reduced chances of simulation sickness.
Strengths:
Reduces simulation sickness
Natural and easy to learn
Weaknesses
Might be obtrusive if users also need their hands for other tasks while navigating an environment
It can be tedious or tiresome after extended use
Can be inefficient when navigating large environments
