  • Patent number: 5974000
    Abstract: A tactilely setable data input structure for a battery-operated, computer-run wrist watch operable in a time mode, a calculator mode and an alphabetic mode comprising a watch casing housing a battery and clock calculator electronics and at least one visible display having multiple units therein. A first button is located on a first side edge of the housing for operating the electronics to cause the visible display to shift between a calculator, alphabetic and a time display upon depression thereof. Further, buttons about the periphery of the watch or watch band are provided. Pressing different combinations of these buttons cause the electronics to create digits zero through nine or alphabetics in a first unit of the display dependent on the combination of specific buttons simultaneously pressed. Multiple entry of digits or alphabetics into the subsequent units of the display allow for creation of multi-digit numbers and words.
