Quote: "Take your smartphone & film when you walk, you get the same wobbling effect !"
Thats your body movement and your head staying still .. You just proved the point
What you see in your phone is not what your head does or you see
However to simulate a walk a wobble is used in Games as Amen points out.
I find the S2 wobble makes my stomach churn so you can go to far with it.
Just to add to Amens comment about VR ..
If someone records in VR walKing with a cheaper camera you get motion sickness very quickly when viewed in VR because it looks just like your smartphone.
The only person ever to get all his work done by "Friday" was Robinson Crusoe..
