Dynamic tactile interface
First Claim
1. A dynamic tactile interface, comprising:
- a substrate defining a fluid channel and a fluid conduit fluidly coupled to the fluid channel;
a tactile layer comprising a peripheral region and a deformable region, the peripheral region coupled to the substrate, and the deformable region arranged over the fluid conduit, disconnected from the substrate, and operable between a retracted setting and an expanded setting, the deformable region elevated above the peripheral region in the expanded setting;
a tube comprising a first end fluidly coupled to the fluid channel and constrained relative to the substrate;
a volume of fluid within the tube;
a displacement device including a fluid vessel and an actuator, the actuator displacing fluid from the fluid vessel into the tactile layer to transition the tactile layer from the retracted setting to the expanded setting and from the tactile layer into the fluid vessel to transition the tactile layer from the expanded setting to the retracted setting; and
a fluid compensation device coupled to the displacement device and adjusting the configuration of the displacement device in response to a change in volume of fluid contained within the fluid vessel,wherein the tube includes a visual indicator, and the visual indicator includes an optically transparent portion of the tube that indicates, to a user, changing the volume of fluid vessel based on the volume of fluid in the vessel.

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.
