ABSTRACT:
A trajectory calculator receiving data indicating initial values of golf ball flight angle, velocity and spin, calculates the apparent elevation and deflection angles at which the golf ball would be seen by an observer at the launch point. An optical object projector projects an image representing the golf ball on a screen. The size of the image decreases with time to yield the apparent perspective size decrease with range. An optional exerciser console enables input of changeable environmental quantities.
