Abstract:
1. A user interface enhancement system comprising: a substrate comprising an attachment face and defining a fluid channel; a tactile layer comprising a tactile surface and a back surface opposite the tactile surface, the back surface connected to the attachment face at a first region of the tactile layer, the tactile layer defining a deformable region over the fluid channel, adjacent the first region, and disconnected from the attachment face; a volume of fluid; a reservoir adjacent the substrate, fluidly coupled to the fluid channel, and containing the volume of fluid; a paddle compressing the reservoir to displace fluid from the reservoir and into the fluid channel to transition the deformable region from a retracted setting to an expanded setting, the deformable region in the expanded setting tactilely distinguishable from the deformable region in the retracted setting; a housing transiently arranged outside an external surface of a body of a computing device to transiently retain an edge of the substrate over a touch sensitive display of the computing device, the housing cooperating with the substrate to enclose the reservoir and the paddle, the reservoir arranged between the housing and the external surface of the body of the device; and an actuator supported by the housing, engaging the paddle and displacing the paddle to compress the reservoir in response to manual actuation of the actuator, the paddle comprising a platen and the actuator comprising a slider translationally coupled to the housing, the slider translating the platen relative to the reservoir to compress the reservoir in response to manual actuation of the slider.
