Basically, this is the same with my previous question:
Principle in Hand Gesture Design, but now for Motion.
I want to design Motion. By motion, I mean the movement may be made by human, like 'move to the right', 'moving hand to the right or left', etc. I design it to be tested on a UI like webpage, e.g. 'moving hand up-down' for 'scrolling'.
So, is there any known principle, guidance, consensus, or standard in designing motion? Or, since it's related to human body, say it needs to be natural, but how to know what's natural what's not, what's the standard should be used?
In case I ask in wrong place or there's lack of information, please tell me. Thank you very much.
