Abstract
A method for displaying a series of images on a projection screen as a function of a position of a presenter in front of the projection screen. First, the width of the screen is divided into a number of segments of selected widths. The positions of each of the segments is stored in a memory. The position of the presenter is compared with the stored segments to identify the segment currently occupied by the presenter. An image control signal is generated when the presenter changes position from a first segment to a second segment
