  • Publication number: 20230122318
    Abstract: In aspects, zoned haptic effects are provided by assigning a plurality of zones corresponding to each of a plurality of zone actuators for providing haptic effects. A desired haptic response is provided for zones selected for actuation, and the response by the zone actuators is detected. Adjacent and non-adjacent zones are assigned for the detected zones as being driven by any of the plurality of zone actuators. Vibration on the adjacent and non-adjacent zone is suppressed in accordance with control parameters associated with the respective adjacent and non-adjacent zones. If a duration of the provided haptic effect has not passed, the suppression of vibration in the adjacent and non-adjacent zones is maintained and if the duration has passed, the suppression of vibration is terminated.
