Efficient selection of characters and commands based on movement-inputs at a user-inerface

摘要

An example method involves: providing a user-interface having a plurality of input regions, where one of the input regions is a home region, where each of the input regions is associated with a primary character from a set of primary characters, and where at least one of the input regions is associated with a subset of secondary characters from a set of secondary characters; receiving data indicating an input-movement from the home region to a second input region from the plurality of input regions that is associated with a subset of secondary characters; receiving data indicating an input-movement from the second input region to the home region; selecting, in response to the input-movement from the second input region to the home region, a character from the subset of secondary characters associated with the second input region; and causing the selected character to be displayed on a graphical display.
