An electronic device for use with a touch-sensitive display, the electronic device comprising: a processor that is configured to: display indicia on the touch-sensitive display that can be touch selected by a user; define a size and location of a plurality of selection zones on the touch-sensitive display that are each associated with different ones of the indicia; identify a first one of the selection zones that has been selected by the user on the touch-sensitive display; output a first one of the indicia that is associated with the first selection zone; and change the size of a second one of the selection zones in response to it being associated with a second one of the indicia that is more likely to be selected next following selection of the first selection zone associated with the first indicia than at least another one of the selection zones, characterized in that: the size of the second selection zone is changed, for each side of the second selection zone, by selectively expanding or contracting the location of at least a portion of the side toward or away with respect to another selection zone immediately adjacent to the side based on comparison of the likelihood that the second indicia will be selected next compared to the likelihood that an indicia associated with the another selection zone immediately adjacent to the side will be selected next. a processor that is configured to: display indicia on the touch-sensitive display that can be touch selected by a user; define a size and location of a plurality of selection zones on the touch-sensitive display that are each associated with different ones of the indicia; identify a first one of the selection zones that has been selected by the user on the touch-sensitive display; output a first one of the indicia that is associated with the first selection zone; and change the size of a second one of the selection zones in response to it being associated with a second one of the indicia that is more likely to be selected next following selection of the first selection zone associated with the first indicia than at least another one of the selection zones, characterized in that: the size of the second selection zone is changed, for each side of the second selection zone, by selectively expanding or contracting the location of at least a portion of the side toward or away with respect to another selection zone immediately adjacent to the side based on comparison of the likelihood that the second indicia will be selected next compared to the likelihood that an indicia associated with the another selection zone immediately adjacent to the side will be selected next. display indicia on the touch-sensitive display that can be touch selected by a user; define a size and location of a plurality of selection zones on the touch-sensitive display that are each associated with different ones of the indicia; identify a first one of the selection zones that has been selected by the user on the touch-sensitive display; output a first one of the indicia that is associated with the first selection zone; and change the size of a second one of the selection zones in response to it being associated with a second one of the indicia that is more likely to be selected next following selection of the first selection zone associated with the first indicia than at least another one of the selection zones, the size of the second selection zone is changed, for each side of the second selection zone, by selectively expanding or contracting the location of at least a portion of the side toward or away with respect to another selection zone immediately adjacent to the side based on comparison of the likelihood that the second indicia will be selected next compared to the likelihood that an indicia associated with the another selection zone immediately adjacent to the side will be selected next.
