recorded by GDC of Google Earth VR
When using the locomotion method of pulling or dragging an avatar through space, cone dragging is a correction trick that moves users vertically in space based on where they’re pulling themselves towards, in order to avoid running into buildings or mountains.
Strengths:
Fast, efficient, and natural for covering great distances
Avoids running into buildings, mountains or other obstacles
Quick to learn for new users
Weaknesses
It can cause simulation sickness, which is why in this case it was used with a minimized field of view during movement
