Abstract:
1. A user interface, comprising: a substrate; a tactile layer comprising a tactile surface, a deformable region of the tactile layer cooperating with the substrate to define a cavity, and a peripheral region of the tactile layer coupled to the substrate adjacent a perimeter of the cavity; a volume of fluid arranged within the cavity; a displacement device configured to manipulate the volume of fluid to transition the deformable region from a retracted setting to an expanded setting, the deformable region flush with the peripheral region at the tactile surface in the retracted setting and offset from the peripheral region at the tactile surface in the expanded setting; a sensor comprising a set of sensing elements, each sensing element in the set of sensing elements configured to sense a capacitance value across a portion of the tactile layer; and a processor configured to detect an input on the tactile surface at the deformable region in the retracted setting according to an output of the sensor and a retracted setting sensor input threshold, the processor further configured to detect an input on the tactile surface at the deformable region in the expanded setting according to an output of the sensor and an expanded setting sensor input threshold that differs from the retracted setting sensor input threshold.
