  • 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.
