“…This type of 3D might better reflect our everyday use of stereopsis. A weak, even null, correlation between dynamic and static stereoacuity has been documented before [ 25 , 26 ]. More recently, Tidbury & al [ 27 ] showed that dynamic disparities were more effective for generating depth perception than static ones.…”

3D vision develops during childhood and tends to diminish after 65 years of age. It is still relatively unknown how stereopsis is used in more complex/ecological contexts such as when walking about in crowds where objects are in motion and occlusions occur. One task that shares characteristics with the requirements for processing dynamic crowds is the multiple object-tracking task (MOT). In the present study we evaluated the impact of stereopsis on a MOT task as a function of age. A total of 60 observers consisting of three groups of 20 subjects (7–12 years old, 18–40 years old and 65 years and older) completed the task in both conditions (with and without stereoscopic effects). The adult group obtained the better scores, followed by the children and the older adult group. The performance difference between the stereoscopic and non-stereoscopic conditions was significant and similar for the adults and the children but was non significant for the older observers. These results show that stereopsis helps children and adults accomplish a MOT task, but has no impact on older adults’ performances. The present results have implications as to how populations differ in their efficiency of using stereoscopic cues for disambiguating complex dynamic scenes.

Research issues that can be addressed by combining stereoscopic and kinetic depth displays include cue conflict and recalibration, mutual constraints, specialization of cues, and differential effects of disparity and kinetic depth on other perceptions, such as size constancy. Methods of producing dynamic stereoscopic displays are reviewed, especially displays combining stereoscopic with orthographic projections of rotation in depth. A sample personal computer program in Pascal is provided.Two of the most important contributions of computer technology to vision research have been in the areas of stereoscopic depth perception (Julesz, 1960) and kinetic depth perception (Green, 1961). There are important reasons for bringing together these two areas of research, and during the past several years a number of investigators have made use of current computer technology to do so. This paper considers research issues that have been or can be addressed by combining binocular disparity and kinetic depth in dynamic stereoscopic displays. The first part reviews five major research issues, some of which overlap: cue conflict and recalibration, mutual constraints, specialization of cues, dynamic versus static disparity, and implications of disparity and kinetic depth for other perceptual judgments. The second part considers implementation. Calculations required for dynamic stereoscopic displays are discussed, including displays in which the stereo pairs are constructed from frames in the motion sequence. Methods of viewing these displays are reviewed, and a sample program in Pascal is provided in an Appendix.
