Abstract
A haptic element having a rotating element at least partially fixed to the rotating shaft of a motor. The rotating element dynamically reconfigures its center of mass to provide at least a first concentric rotation state and second eccentric rotation state. The transition between the concentric state and the eccentric state may be at least partially defined by a threshold angular velocity of the rotating shaft of the motor. As the motor approaches the threshold, the rotating element may be concentrically aligned with the axis of rotation of the rotating shaft of the motor. Once the threshold is reached, the mass element may be eccentrically aligned with the axis of rotation, initiating an immediate and perceivable haptic feedback.
