Abstract
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 m…
