  • Publication number: 20210364054
    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.

  • Patent number: 11138843
    Abstract: A haptic-enabled system, non-transitory computer-readable medium, and method for controlling a haptic actuator are presented. The haptic-enabled system comprises the haptic actuator, a movement sensor, and a control circuit. The control circuit is configured to: generate a driving portion of a drive signal; apply the driving portion of the drive signal to the haptic actuator to generate movement of one or more portions of the haptic-enabled system; determine (e.g., measure) the movement of the one or more portions of the haptic-enabled system; determine a time-varying correction signal for reducing the movement; generate a braking portion of the drive signal based on a combination of the time-varying correction signal and a defined offset; and apply the braking portion of the drive signal to the haptic actuator. Numerous other aspects are provided.

  • Publication number: 20210232308
    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.

  • Publication number: 20210157408
    Abstract: Systems and methods for multi-directional haptic effects for haptic surfaces are disclosed. One exemplary system includes one or more resonant actuators coupled to a surface, the one or more resonant actuators configured to generate a haptic effect comprising vibrations in a plurality of nonparallel directions, the haptic effect configured to displace the surface, and the vibrations being within a two-dimensional plane that is substantially parallel to the surface; a processor in communication with the one or more resonant actuators; and a non-transitory computer-readable medium comprising instructions that are executable by the processor to cause the processor to: detect an event; generate at least one haptic drive signal based on the event; and transmit the at least one haptic drive signal to the one or more resonant actuators, the one or more resonant actuators further configured to receive the at least one haptic drive signal and responsively output the haptic effect.

  • Publication number: 20210159813
    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.

  • Publication number: 20210157407
    Abstract: In aspects, a touch surface assembly and a method of providing thereof are provided. For example, a touch surface assembly includes a touch surface, a haptic actuator configured to provide a linear motion along a motion axis of the haptic actuator to provide a haptic effect on the touch surface, and coupled to the touch surface such that the motion axis of the haptic actuator forms an angle with a centerline of the touch surface, and suspension components configured to provide damping with resonance for a motion of the touch surface. A first set of at least two suspension components of the suspension components are coupled to the touch surface along or substantially along the motion axis, and a second set of at least two suspension components of the suspension components are coupled to the touch surface along or substantially along a neutral axis of the haptic actuator that is perpendicular to the motion axis.

  • Publication number: 20200150767
    Abstract: A haptic-enabled device having a haptic actuator, a movement sensor, and a control circuit is presented. The control circuit determines a drive signal for the haptic actuator based on desired movement for a haptic effect and based on a model that describes transient behavior of the haptic actuator. The control circuit further measures movement output by the haptic actuator based on the drive signal being applied to the haptic actuator. The control circuit determines a movement error that indicates a difference between the measured movement and the desired movement, and adjusts the drive signal based on the movement error to generate an adjusted drive signal. The adjusted drive signal is applied to the haptic actuator to generate the haptic effect. Numerous other aspects are provided.
