When a frame rate is decreased or an image moves fast, jerky movement called “jerkiness” is perceived. A number of researches have been done to characterize jerkiness for 2D images. However, jerkiness for 3D images has not been studied. The aim of this research is to characterize jerkiness for a high-density directional display that has been developed as a natural 3D display. In this paper, we conducted subjective evaluations under static viewing condition. We found that jerkiness was more noticeable for a nearer 3D image, and jerkiness was less noticeable for a further 3D image. We showed that, when a velocity of 3D image was described by a visual angle velocity, detection threshold and tolerance threshold of jerkiness were determined by a visual angle velocity and a frame rate. This characteristic is equivalent to that which had already been reported for 2D images. |
