Elliptec Resonant Actuator AG
Different types of knobs
Knop with endstop: - often for analog values- inexpensive - same position sam value- often no raster
Knop with centering:- Turn and hold to change values- multi speed increment / decrement- Shuttle dials
Endless wheel with raster- multi parameters
- increment / decrement- combination with button.

Elliptec Resonant Actuator AG
Generate sensible force(agaist finger pressure)
Change direction of force(on each edge)
Build pattern with changing
direction of forces(when let loose motor moves to next zero)
Idea: human force is stronger than motor force
