Apple is using only vague words to describe their haptic touchpad.
I had the occasion to test one and I was surprised by how it felt : I wouldn't have told the surface was not been "clicked" down.
What range of frequency the coils are vibrating on?
What does the signal looks like?

Oh, yeah. that's what I meant.

It might be possible to perfectly replicate the sensation of clocking actual buttons. The buttons travels such a small distance that we wouldn't notice it traveling. The only thing we sense might be the vibration.

It doesn't feel anywhere as real if you actually used a previous Mac trackpad or any Trackpad with a real button.
Also this is an ergonomic nightmare since while you're expecting a real click while the haptic touch, instead it just tricks you while your wrist takes the full brunt of the force because there's no physical give. Tap on a solid table over and over and see how long your wrist lasts.

Yeah, it's weird because you don't think about it at all until it's off or asleep, then you press it and it's completely solid.

What frequencies?
According to http://www.ucalgary.ca/pip369/mod7/touch/somato2
it should be around 10 ~ 500 Hz but the feeling was "sharp" somehow...

I never owned apple device. I just had the occasion to use one from a guy in my lab. The few minutes I had it under my hands I was quite surprised.

Thank you.
>it allows what feels like instantaneous feedback which can be calibrated to mimic responses such as clicking.
>The vibrations were programmed through wavefunctions which describe amplitude (how strong the vibration is) and frequency.
I guess I'll have to read the thesis at https://dspace.mit.edu/handle/1721.1/29094#files-area to know more.
