Abstract
A method for assisting user input to a device, comprising the steps of providing a user interface to retrieve a user input, providing a tactile interface layer that defines a surface and includes a volume of fluid and a displacement device that manipulates the volume of fluid to deform a plurality of particular regions of the surface into tactilely distinguishable formations that each represent a key of a key interface, allowing the user to provide input through the key interface, predicting a subsequent key input when a user provides an input through the key interface, and manipulating the volume of fluid to deform the plurality of particular regions into one of two types of tactilely distinguishable formations: a first type for tactilely distinguishable formations that represent a predicted key and a second type for tactilely distinguishable formations that represent an unpredicted key.
