I actually use Apple's accessibility features quite a bit. I'm not visually or aurally imparied, but sometimes I like the features provided to those users. Apple seems to care quite a bit in this regard.

I haven't looked into Apple's 3D Touch documentation very deeply, but the OS seem to respond, by default, to just three levels of pressure -- the first, the lightest, is treated as a traditional touch. The next level we might call a press, and is given an immediate "taptic" feedback, to differentiate from a touch. A "deeper press" gives another haptic response. In fact, it vibrates/taps twice as an error, if deeper press is not supported on the element.
