Abstract:
1. A method for assisting user input, comprising: displaying a set of keys on a display coupled to a substrate, the substrate coupled to an undeformable region of a tactile layer, the tactile layer comprising a set of deformable regions adjacent the undeformable region, each deformable region in the set of deformable regions disconnected from the substrate, configured to deform into a tactile formation above the undeformable region, and corresponding to a key in the set of keys; receiving a selection of a first key in the set of keys; predicting a selection of a subsequent key based on the selection of the first key, the subsequent key corresponding to a first deformable region in the set of deformable regions; and manipulating a volume of fluid to transition the first deformable region into a first tactile formation and to transition a second deformable region, in the set of deformable regions, into a second tactile formation, the first tactile formation tactilely distinguishable from the second tactile formation, the second deformable region corresponding to an unpredicted subsequent key; and enabling selection of the predicted subsequent key through the first deformable region and selection of the unpredicted subsequent key through the second deformable region.
