Frictional Widgets: Enhancing Touch Interfaces with Programmable Friction
Extended Abstracts of ACM CHI'11 Conference on Human Factors in Computing Systems, Vancouver, Canada, May 2011, pp. 1153-1158.download pdf
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.
