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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
