Abstract

A pointing device includes a controller for pointing a position on a display surface by imaging an imaging objective such as two markers positioned with a predetermined interval therebetween in a vicinity of the display surface of a monitor. With the pointing device, a width of the display surface and the interval between the markers are obtained to determine an appropriate distance between the controller and the monitor. Further, a current distance between the controller and the monitor (markers) is calculated. Relation between the current distance and the appropriate distance is notified by such as image display or sound output. For example, an image indicating the appropriate distance and an adjustment image varying in size in conjunction with the current distance are displayed on the monitor.
