There are two variants of a device for data input and a method for providing the same. The first variant of a device contains an element for information choice with an appliance for its positioning and an executive element. It comprises a housing or a panel placed on it with a movable element for information choice, provided with its position control elements and an executive element with attached contacts of electrical circuit of input confirmation. The movable element for the symbol choice is provided with an appliance for searching a group of symbols, which includes the necessary symbol and an appliance for searching the symbol within the group. The movable element is realized as a button mounted in the panel window. The appliance for search and choice of a group and the symbol contains radially directed guiding lines, for example, radial slits in the panel. The second variant of a device for data input lies in realization of the appliance for searching a group of symbols and the necessary symbol as a button, mounted in the panel hole with a certain transversely directed backlash. Contacts of electrical circuit of choosing a symbols group and contacts of electrical circuit of choosing a symbol within a group are mounted within the length of a button backlash and are closing at the button transversal movement. A method for data input into an information system, comprising fulfillment of search, choice and input of the required symbol, wherein a set of all input symbols is preliminary divided into groups and then the two-step search is carried out: step 1-search of the group of symbols which includes the necessary symbol; step 2-search of the necessary symbol therein. |
