| Abstract |
| The effort of implementing realistic 3-D depth on 2-D images has been continued persistently with a theoretical understanding of depth perception and its related technical development. The present article briefly reviews a number of popular stereoscopes for studying stereoscopic depth perception according to their implementation principles, and introduces a behavioral experiment as a technical example in which the active-shutter glasses were used. In the present study, participants were tested for their visual memory against perceived depth among a set of items, The depth of the memory and test items was manipulated to be 1) monocular, 2) binocular, or 3) both-monocular-and-binocular respectively, The memory performance was worst in the binocular-depth condition, and best however in the both-monocular-and-binocular condition. These results indicate that visual memory may benefit more from monocular depth than stereoscopic depth, and further suggest that the storage of depth information into visual memory would require both binocular and monocular information for its optimal memory performance. |
