Abstract

Abstract— The jerkiness of moving three-dimensional (3-D) images produced by a high-density directional display was studied. Under static viewing conditions in which subjects' heads did not move, jerkiness was more noticeable when moving 3-D images were displayed in front of the display screen and was less noticeable when moving 3-D images were displayed behind the screen. We found that the perception of jerkiness depended on the visual angular velocities of moving 3-D images. Under dynamic viewing conditions in which subjects' heads were forced to move, when moving 3-D images were displayed in front of the screen, jerkiness was less noticeable when the subjects' heads and 3-D images moved in opposite directions and was more noticeable when they moved in the same direction. When moving 3-D images were displayed behind the screen, jerkiness was less noticeable when subjects' heads and 3-D images moved in the same direction and was more noticeable when they moved in opposite directions.
