ABSTRACT:
A data input device for inputting data in the form of patterns to an electronic device such as an electronic timepiece is disclosed. Data input is performed by tracing out patterns, each representing a character, numeral or symbol, such as to successively actuate a plurality of sensor elements, which can comprise touch-sensitive electrodes arrayed over a display device, and pattern recognition is performed by interpreting pairs of successive sensor element actuations as lines of an input pattern, rather than separately interpreting individual sensor element actuations as point inputs.
