Abstract

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.
