Abstract: A haptic output device is configured to generate a deformation-based haptic effect and a vibration-based haptic effect. The haptic output device includes a shape memory material configured to change a shape thereof when heated and generate the deformation-based haptic effect, and a cooling device configured to cool the shape memory material and generate the vibration-based haptic effect.

Abstract: A system includes a wearable electronic device and a strap operatively connected to the wearable electronic device. The strap is configured to allow a user to wear the wearable electronic device on a body part. The system also includes an actuator connected to the strap, and a processor in signal communication with the wearable electronic device and the actuator. The processor is configured to receive a first signal from the wearable electronic device and send a second signal, based on the first signal, to the actuator to cause the strap to move relative to the wearable electronic device and provide a haptic effect to the user.

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.

Abstract: A haptic actuator assembly comprising a fluid reservoir and an actuator is presented. The fluid reservoir may hold a substantially non-compressible fluid, and has a first layer and a second layer that is less rigid than the first layer. The first layer has a first resonance frequency, and the second layer has a lower resonance frequency. The actuator is configured to cause a first vibration in which the first layer vibrates at the first resonance frequency and provides a first amount of displacement or acceleration. The fluid reservoir is configured to transfer a force of the first vibration from the first layer to the second layer to cause a second vibration in which the second layer vibrates at the lower resonance frequency and provides a second, higher amount of displacement or acceleration.

Abstract: A system having a haptic control unit, a haptic delivery cluster, and an electric field generator, magnetic field generator, or pneumatic actuator is presented. The haptic delivery cluster comprises a plurality of haptic delivery nodes, wherein each haptic delivery node of the plurality of haptic delivery nodes is separate from other haptic delivery nodes of the plurality of haptic delivery nodes, is at least one of a wireless communication device, a sensor, or a computing device, and has a dimension that is less than or equal to 5 mm. The electric field generator, magnetic field generator, or pneumatic actuator is in communication with the haptic control unit and is configured, when activated, to generate an electric field or a magnetic field in a physical environment in which the haptic delivery cluster is located, or to output a pulse of air in the physical environment.

Abstract: The present application relates generally to haptic feedback actuators and their construction and use in touch based systems. The haptic feedback actuators are suitably bilayer structures including at least two materials having different thermal coefficients, allowing the structure to deflect from a first position to a second position in response to heating and/or cooling of the structure.
