Abstract
A manual controller of a video game system has a plurality of control switches for controlling the motion of an image displayed on a display screen, and an analog joystick for designating a point in a given area on the displayed image. When the analog joystick is operated by the game player of the video game system, it is tilted to a position in a desired direction in a two-dimensional plane, and outputs a positional signal depending on the tilted position thereof. A coordinate transforming unit converts first and second two-dimensional coordinates of the tilted position respectively into third and fourth two-dimensional coordinates of an image position with respect to a predetermined reference position on the displayed image, with a first conversion constant for converting the first coordinate into the third coordinate and a second conversion constant, which is different from the first conversion constant, for converting the second coordinate into the fourth coordinate.
