I'm wondering why a haptic class is needed when there is force
feedback support. Admittedly, I don't know the force feedback
implementation too well, but could someone please enlighten me on
this? Am I missing something here?
I see haptics as simple force feedback, just with (usually) small
force and short duration. There are devices out there doing haptics
using vibra motors, which I think would be limited if implemented
using this haptics class driver. Would it be somehow problematic
interfacing with the simple haptic hardware using the force feedback
API?
BR,
Jani.
