The data input device permits the selection of a symbol amongst a set of N symbols, e.g. for memorizing a message. A data input device permitting selection of a particular symbol from amongst a set of N symbols includes a display subdivided into K distinct display zones and K selecting elements, each K selecting element being associated with a specific one of the K distinct display zones. The device may be used, for example, in an electronic diary watch to select alphanumeric symbols and thereby record a message for use in the diary mode of operation. A microprocessor connected to the display and selecting elements first causes the set of N symbols to be divided and displayed equally among the K distinct display zones upon manual actuation of a data selection switch. Subsequently, manual actuation of one of the K selecting elements causes the microprocessor to select the symbols of the distinct display zone associated with the actuated selecting element; these selected symbols are equally distributed and displayed among the K distinct display zones. This selecting process is repeated until the desired symbol is isolated and displayed in one of the K distinct zones, at which point manual actuation of the selecting element corresponding to that particular display zone causes the microprocessor to select and memorize that desired symbol. This selecting process is then repeated for each symbol of the message to be memorized. |
