Touch interactions occur through flat surfaces that lack the tactile richness of physical interfaces. We explore the design possibilities offered by augmenting touchscreens with programmable surface friction. Four exemplar applications - an alarm clock, a file manager, a game, and a text editor - demonstrate tactile effects that improve touch interactions by enhancing physicality, performance, and subjective satisfaction.
