Haptic feeling is measured by acceleration. However, how the Human being take the acceleration? I am wondering how long period effective acceleration really matters. Thank you!
Dear Leon,
From Newton's second law , we sense it as force , if we tend to resist ?
In motion , I would say relates to momentum too.

I thought the question related to how long of a period of time the acceleration must be maintained, for it to be effective.
I've not answered, because I think "it depends." If you want to emulate absence of gravity, that would be tough to do indeed, for more than just a few seconds.
Albert, you are right. Thank you! My question is more of the haptic of human finger on cell phone screen. Do you have any insight?
Best Regards,
Leon
Leon, no particular insight from me. Although on any type of touchpad or screen, your acceleration is going to be very limited by the range of motion possible, in any case. Experimentation is all I can suggest.
