Abstract

A device for generating a haptic moment at an actuator including an unbalance motor, a sensor for sensing activation of the actuator, and a processor for generating an actuation signal for the unbalance motor depending on signals of the sensor, wherein the processor is embodied so that, when activation of the actuator is sensed, the processor generates a first actuation signal and generates a second actuation signal, wherein the first actuation signal is configured so the unbalance motor is accelerated in a first rotational direction without reaching more than two revolutions, and the second actuation signal is configured so the unbalance motor is braked without the unbalance motor starting to move in the second rotational direction.
