Abstract

Various items (corresponding to characters, symbols, numerals, or function specifications) are displayed, the desired item being then selected, through, for example, a mouse cursor, and the selected item being thus input. Thus, neither the apparatus nor the method require a keyboard. A display changing unit changes, in a predetermined sequence, a display of a group of items from among a plurality of groups of items. The item to be input is then selected from the corresponding group of items of the plurality of groups of items through an item selecting unit.
