Abstract: A support structure includes a fixed frame portion configured to provide a fixed connection point for the support structure. The support structure also includes a suspended frame portion configured to support the interactive device and configured to oscillate in a direction of motion relative to the fixed frame portion due to a force applied to at least one of the fixed frame portion or the suspended frame portion by an actuator configured to provide a haptic effect to the interactive device. Further, the support structure includes one or more support members coupled between the fixed frame portion and the suspended frame portion. The direction of motion is defined by the one or more support members. The one or more support members provide a restoring force that causes the suspended frame portion to undergo harmonic oscillation in the direction of motion in response to the force applied by the actuator.

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. Numerous other aspects are provided.

Abstract: Systems, methods, and devices for control of actuators are provided. In aspects, the systems, methods, and devices provided herein enable the generation of sharp cutoff haptic effects of both limited and extended duration. The systems, methods, and devices use open loop braking signals to generate the sharp cutoff haptic effects. The braking signals are determined based on predictions of system response made according to driving signals used to cause the haptic effects in the actuators. Numerous other aspects are provided.

Abstract: Systems, methods, and devices include at least one actuator positioned within proximity of a user interface (UI) region of an interactive surface. The UI region outputs information to a user and receives input from the user. The at least one actuator provides a haptic effect to the user when interacting with the UI region. The system also includes at least one isolation element positioned adjacent to the at least one actuator. The at least one isolation element suppresses transmission of the haptic effect to an additional UI region of the interactive surface.
