One approach to building cheap, high-resolution displays is using a large number of standard LCD monitors. The problem is that those cannot easily display stereo images to convey three-dimensional information to the user. However, stereo viewing is only one of many clues that the human visual system uses to distinguish objects at differing depths. Another, similarly string one, is motion parallax.
Stereo vision is the most obvious cue to perceive depth. But analysis has shown that there are many other cues like shading, shadows, occlusion etc. One of the strongest ones, and on par with stereo, is motion parallax. The goal of this project is a perceptual analysis of the effectiveness of different kinds of motion parallax on the depth impression and perception of a variety of users. Many different motions can be imagined (translations left-right, up-down, back-forwards, rotations, and other projection methods, different motion speeds and framerates), which leaves an enormous amount of options that could be useful. To decide which variants are most useful we are working on a study. The study will be done in multiple steps. The first is to run a set of experiments in-house, where users will have a chance to adapt one (of many) parameter of the displayed motion to give the optimal depth impression. The goal is to reduce the possibly immense search space for the optimal display method to something more manageable.
