System and method for a rotary control in a device that comprises a knob, a shaft supporting the knob and coupled to rotate therewith a base supporting the shaft. A sensor, operationally coupled to the base, is configured to detect an aspect of manipulation of the knob, which may include information relating to position, velocity, acceleration, torque, rate of rotation, time of rotation, or a combination thereof. A mechanical haptic assembly is operationally coupled between the base and the shaft to provide mechanical based haptic effects in response to movement of the knob with respect to the base. A programmable electronic-based actuator is operationally coupled to the knob and provides electronic-based haptic force feedback to the knob.
