Abstract:
1. A method for actuating a tactile interface layer coupled to a device, comprising a surface defining a deformable region and a second region adjacent the deformable region, and defining a fluid vessel adjacent the deformable region, the method comprising: displacing a volume of fluid into the fluid vessel to transition the deformable region of the surface from a retracted state into an expanded state the deformable region defining a formation tactilely distinguishable from the surface second region in the expanded state; detecting a force applied to the surface at the deformable region in the expanded state; interpreting the force on the deformable region as a command for a firmness of the deformable region in the expanded setting; and manipulating the volume of fluid to modify the firmness of the deformable region in the expanded setting based on the command.
