Abstract
A perspective view of a pointer icon is displayed such that toward the middle of the display frame the icon appears to point toward the display surface, rather than toward an edge of the display frame. This creates an illusion that the icon, such as an arrowhead, is reversing its direction smoothly in three dimensional space. Although the display screen is only a two dimensional surface, the multiple icons can readily be configured to be shown in perspective and, therefore, appear to be three dimensional, without the requirement for gray scale or half tone display technology. The invention is readily implemented with conventional monochromatic or color graphics hardware commonly available for personal computers.
