Abstract:
A limited Graphics Turing Test is used to determine the frame rate that is required to achieve telepresence of
an animated object. For low object velocities of 2.25 and 4.5 degrees of visual angle per second at 60 frames
per second a rotating object with no added motion blur is able to pass the test. The results of the experiments
confirm previous results in psychophysics and show that the Graphics Turing Test is a useful tool in computer
graphics. Even with simulated motion blur, our Graphics Turing Test could not be passed with frame rates of
30 and 20 frames per second. Our results suggest that 60 frames per second (instead of 30 frames per second)
should be considered the minimum frame rate to achieve object telepresence and that motion blur provides
only limited benefits.
