Effect of Image Update Rate on Moving-Target Identification Range

Zusammenfassung:	In prior research, moving-form perception tended to be nonveridical when the update rate of an image generator (lG) was less than the refresh rate of the display device. In this experiment, we examined the effect of update rate on the range at which pilots could identify computer-generated representations of moving aircraft. For a 60-Hz interlaced display, identification range was greater for a 60-Hz image update rate than for a 30-Hz update rate. This effect held for two views of three pairs of aircraft moving at two different velocities. These results suggest that image update rate is an important design parameter for simulators intended to support air-to-air combat training. To maximize the range at which a moving target can be identified, the update rate of the lG should equal the refresh rate of the display device.
