  • Patent number: 9760172
    Abstract: One variation of a dynamic tactile interface includes: a dynamic tactile layer including a deformable region and a first region, the deformable region operable between a retracted setting and an expanded setting, the first region adjacent the deformable region, the deformable region tactilely distinguishable from the first region in the expanded setting; a displacement device including a fluid vessel and an actuator, the actuator displacing fluid from the fluid vessel into the dynamic tactile layer to transition the deformable region from the retracted setting into the expanded setting and displacing fluid from the dynamic tactile layer into the fluid vessel, transitioning the deformable region from the expanded setting into the retracted setting; and a fluid compensation device coupled to the displacement device and adjusting a configuration of the displacement device in response to a change in a volume of fluid contained within the fluid vessel.

  • Publication number: 20160187981
    Abstract: A dynamic tactile interface includes a dynamic tactile layer and a manual fluid actuator. The manual fluid actuator includes a displacement device including a bladder, a platen adjacent the bladder, an elongated member coupled to the platen, and a rotary actuator, the elongated member and the rotary actuator translating rotation of the rotary actuator into translation of the platen, the platen compressing the bladder in response to rotation of the rotary actuator in a first direction and expanding the bladder in response to rotation of the rotary actuator in a second direction opposite the first direction.
