“The “world’s first” deformable tactile surface capable of creating dynamic physical buttons that users can actually see and feel in advance of entering data into the device, Tactus uses microfluidic technology to create physical buttons that rise from the touchscreen to give users the experience or feeling of operating a physical keyboard. When no longer needed, the buttons recede back into the touchscreen, leaving no trace of their presence. The Tactile Layer panel is a completely flat, transparent, dynamic surface that adds no extra thickness to the standard touchscreen display since it replaces a layer of the already existing display stack.” -TG Daily 

Whoa, a dynamic, physically transforming surface? Incredible implications here - imagine having tables, walls, or doors with “hidden” buttons that can emerge from the surface when called upon.
