Patent ID: 8671344

Claim:
An information display device comprising: a reception unit operable to extract, from a motion vector obtained by a move operation by a user on a two-dimensional plane defined by first and second axes, a motion component along the first axis and a motion component along the second axis, and to receive an instruction for displaying a plurality of contents according to the extracted motion components; a determination unit operable to determine a moving speed for moving the contents, based on the motion component along the first axis, and to determine a display mode for displaying the contents, based on the motion component along the second axis; and a display unit operable to display the contents in the determined display mode on a screen, by scrolling through the contents at the determined moving speed, wherein the screen has a touch panel function, wherein the move operation is an operation performed by the user sliding a finger on the screen, wherein the reception unit is further operable to specify a starting position on the screen which the finger touches at a start of the move operation, and to specify the motion components along the first and the second axes by the move operation, wherein the display unit is further operable to display a predetermined initial figure at the starting position, and subsequently display a figure corresponding to the motion components along the first and the second axes after changing the predetermined initial figure to the corresponding figure, wherein the reception unit is further operable, after the sliding of the finger is performed on the screen, to receive a pressing operation in which pressing of the finger is continuous at an ending position of the sliding, wherein the determination unit is further operable to judge whether or not to maintain the determined moving speed and the determined display mode, based on the pressing operation, wherein the display unit is further operable to stop displaying the contents in the display mode by scrolling through the contents at the moving speed, when the determination unit judges that the moving speed and the display mode are not to be maintained, wherein the determination unit judges that the moving speed and the display mode are to be maintained when judging that a pressing time period at the ending position of the sliding has exceeded a predetermined time period, and judges that the moving speed and the display mode are not to be maintained when judging that the pressing time period has not exceeded the predetermined time period, wherein the determination unit is further operable to measure a time in which the pressing operation at the ending position is being performed, and wherein the display unit is further operable, while the reception unit is receiving the pressing operation, to display at least one of the time that is being measured and a message indicating whether to maintain the determined moving speed and the determined display mode.
