ABSTRACT:
When the user pushes an input button5, upper, lower, left and right input buttons2, 4, 6and8adjacent to the pushed button5are animated convergently toward the pushed button5. Also, the input buttons adjacent to the pushed input button look as if a first side of each adjacent input button adjacent to the pushed input button rotated downward while the second side moved toward the pushed input button. Concerning the movement of one of the adjacent input buttons to be animated, the adjacent input button will look as if one side thereof adjacent to th pushed input button rotated downward about a second side thereof opposite to the first side while the second side moved toward the pushed input button. Thus, the present invention provides a highly user-friendly electronic appliance using a touch panel capable of displaying button images easily discernible by the user even if its display screen is limited in area and each on-screen button occupies the limited display area.
