  • Publication number: 20200184785
    Abstract: Devices and methods for providing localized haptic effects are provided. The devices include a haptically enabled display device having one or more haptic actuators. The one or more haptic actuators are located in a non-viewing area of a display screen of a haptically enabled display device and cause localized haptic effects in a viewing area of the display screen. The haptically enabled display device includes a processor configured to determine haptic control signals for activating the haptic actuators. The haptic control signal activates the one or more haptic actuators to provide a localized haptic effect at a target location in the viewing area, remote from the non-viewing area location of the one or more haptic actuators.

  • Patent number: 10678364
    Abstract: A touch input system comprising a touch input device and an actuation and sensing system is presented. The actuation and sensing system has a transfer structure adjacent to a first surface of the touch input device, the transfer structure having a first portion and a beam extending from an edge of the first portion. The actuation and sensing system further has a transducer patch disposed on the beam. The transfer structure is configured to transfer forces between the touch input device and the transducer patch, such that movement of the touch input device by an external force causes deformation of the beam and of the transducer patch, and such that actuation output by the transducer patch causes movement of the touch input device. The transducer patch has a layer of transducer material that is configured to act as a sensor, and is configured to act as an actuator.

  • Publication number: 20200125173
    Abstract: Friction based kinesthetic actuation systems are provided. The friction based kinesthetic actuator systems include at least a friction based kinesthetic actuation device and a user interface element. One or more actuation beams, including at least a friction head and a smart material element, of the friction based kinesthetic actuation device act on the user interface element. Activation of the smart material element applies or increases a normal force between the friction head and an actuation surface of a user interface element. The normal force allows the generation or increase of a friction force between the friction heads of the actuator and the actuation surface. The friction force between the actuator and the actuation surface of the user interface element generates a kinesthetic effect at the user interface element.

  • Publication number: 20200103966
    Abstract: A haptic actuator comprising an elongate bladder, a pressure control component, and a constraining structure. The elongate bladder is stretchable along a length dimension thereof. The pressure control component is configured to increase pressure of a fluid in the bladder, which causes a first surface portion of the elongate bladder to stretch along the length dimension thereof. The constraining structure is attached to a second and opposite surface portion of the elongate bladder and is less stretchable than the elongate bladder so as to constrain the second surface portion of the elongate bladder from stretching along the length dimension thereof. When the pressure control component is activated to increase the pressure of the fluid, the constraining structure permits the first surface portion to stretch along the length dimension by a greater amount relative to the second surface portion, which causes the elongate bladder to bend.

  • Patent number: 10583359
    Abstract: A wearable device for providing haptic effects includes a wearable housing configured to be worn on to a portion of a hand of a wearer and an actuator secured to the wearable housing. The wearable housing includes a first digit segment configured to conform to a finger of the hand and a second digit segment configured to conform to another finger or a thumb of the hand. The actuator is configured to receive a command signal indicative of a virtual interaction related to touching or grasping a virtual object. In response to the command signal, the actuator provides a force onto the portion of the hand or provides a force to render a resistance to movement of the first and second digit segments toward each other. The actuator uses the wearable housing to mechanically stabilize the force towards the portion of the hand.

  • Patent number: 10585483
    Abstract: A haptic actuator assembly includes a haptic actuator configured to output displacement along a perpendicular axis and a pre-load device. The pre-load device is disposed adjacent to the haptic actuator and configured to generate a compressive load on the haptic actuator along the perpendicular axis to oppose expansion of the haptic actuator along the perpendicular axis. The haptic actuator is disposed within an enclosed cavity formed by a casing. A pressure within the enclosed cavity is varied in order to create the compressive load on the haptic actuator along the perpendicular axis. The pre-load device may alternatively be a connector component formed from a shrinkable material that is configured to longitudinally shrink to exert a force in order to create the compressive load on the haptic actuator along the perpendicular axis.
