GAME PROGRAM AND GAME DEVICE USING TOUCH PANEL

Reading from a RAM, image data of a rotating object, and displaying the rotating object on the display screen; obtaining touch position coordinates on the touch panel; when a contact to the touch panel is performed, calculating at each interval of a given period, an angle variation amount between coordinates displaying a rotation axis of the rotating object and the touch position coordinates; periodically adding to an operation parameter stored in the RAM, a value resulting from a multiplication of a coefficient with the angle variation amount, wherein the coefficient changes in accordance with a size of the parameter; and changing a display angle of the rotating object on the display screen in accordance with a change in the operation parameter. Therefore, there is realized an input operation for controlling a movement of an object by using a touch panel, wherein the input operation has good operability without being monotonous.
