Abstract: An electronic device includes an input screen including: a dial keyboard on which multiple characters are annularly arranged for selection by an operator; an input area into which a character selected from the multiple characters is input at an input position; and a movement key for allowing the operator to move the input position at which the selected character is to be input in the input area to determine the input position. The dial keyboard sequentially displays the multiple characters for selection by the operator on the dial keyboard, according to an operation on the dial keyboard by the operator. The input area displays the selected character at the input position determined in response to an operation on the movement key, in response to a selection of a character from the multiple characters by the operator.
