- Haptic feedback while dragging: feel when you hit the end of a scrolling page or list, or when something you're dragging gets over a target. ANY user can benefit from that kind of added feedback. (But it will take time for developers to get used to what works best vs. what's a gimmick.)
This could be very useful for accessibility... I'd imagine vision-impaired users would find this kind of haptic feedback very useful when navigating UI elements.
