Effects of observation duration on depth perception from motion parallax
Details
Generally motion parallax studies assume that there is linear movement between the object with the observer.. However a relative motion stimulus is able to be interpreted as both linear movement and rotation. In this study we investigated perceptual alternation between linear movement and rotation during 5 minutes observation on a relative motion stimulus. As a result, observer perceived mostly linear movement in the first 120 seconds. After that, however, their perception is altered between linear and rotational movement. Additionally, perceptual depth order is also reversed as perceptual motion is altered.
