Abstract

Touch interactions take place through flat surfaces that lack the tactile richness of physical interfaces and hence do not fully exploit our sense of touch. This collaborative work explores the reintroduction of rich tactile feedback in touch interfaces through the use of programmable surface friction. Using Northwestern University's Large Area Tactile Pattern display (LATPaD), we demonstrate that programmable friction can not only improve performance in targeting tasks but also have a positive impact on the enjoyment, engagement and sense of realism experienced by users of touch interfaces.
