    Abstract: The defacto standard for text entry on standard telephone keypads, such as fixed phones, cell phones, fax machines, and the like is a multi-tap method where one of several letters associated to a input means is selected by pressing the input means a number of times equal to the position of the desired letter in the ordering of letters associated to the input means. Typically, for the standard alphabetic ordering, a large number of presses are required to obtain any given letter. The present invention uses prefix information to dynamically reorder the choices so that the average number of input means manipulations is reduced. This method is applicable to any language composed of strings of symbols for which the probability of any given symbol appearing in a string at a given position is correlated with the probability of another symbol appearing in the string.
