An information display device includes an input interface that accepts an input manipulation including setting a starting location and a destination, and a processor that displays in a display area, an object and a manipulator for use to enter an instruction to change the display state of the object. The processor changes the display state in accordance with a vector to be defined by the distance and direction from the starting location to the destination. The processor performs a first type of processing in response to the input manipulation done on a region other than a region of the manipulator, and a second type of processing of changing the display state in response to the input manipulation done on the region of the manipulator. In the second type of processing, the display state of the object can be changed more finely than in the first type of processing.
