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 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: 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.
