Abstract
In a display apparatus for presentation including an image display device 30 that allows for moving a selection marker across a plurality of menu items arranged in vertical and horizontal directions and displayed on a screen 1 in accordance with received angular velocity information, a menu item to which the selection marker should be moved is determined in accordance with the number of cycles of angular velocity sampling during which the move distance of the pointing device obtained for every sampling cycle from the angular velocity information exceeds a predetermined value continuously. This improved the inconvenience to use with a conventional pointing device in which a distance by which an object should be moved on the display screen is proportional to the entire distance over which the pointing device was moved, calculated from angular velocity; thus, the operator has to tilt the remote controller incorporating a gyroscope to a large extent to move the object by a long distance on the screen.
