ABSTRACT:
An improved rear projection screen for projecting a three-dimensional head or face is designed to accurately match the apparent movement of a imaged person eyes to movements of an observer, thereby maintaining eye contact between the imaged person and the observer as the observer moves relative to the image. This unique effect called "visualactivity" enables either a recorded or a live image of a person to engage observers with eye contact in a natural and interpersonal way despite movement of the observers relative to the image. This effect is achieved by projecting an image onto the convex side of a rear projection screen that roughly has the shape of a human head and face but is configured with proportions that are different from the natural proportions of the imaged person's face. When viewed from the concave side, this combination produces a realistic human face that appears to turn to accurately track an observer's movements.
