An electronic apparatus having a user interface for symbol input is
disclosed. The apparatus has a display and an input device having an
elongated touch-sensitive sensor area and capable of detecting user
actuations of a plurality of sensor positions along a main axis of the
elongated touch-sensitive sensor area. The apparatus also has a
processing device coupled to the display and the input device. In
response to a user actuation of a current sensor position among said
plurality of sensor positions of the input device, the processing device
determines, from the current sensor position, a current symbol position
in a symbol sequence, and then controls the display to indicate a current
symbol held by the current symbol position in the symbol sequence.
