The ZeitRaum series (2011-13) consist of 5 projects (click on title for further details):
This project is situated at the junction of visual perception and related cognitive processes. It investigates how visual cues such as motion parallax, binocular vision and binocular rivalry affect the human ability to perceive depth in a scene. The sense of space, magnitude and range of perceived depth and the apparent scale of a scene are determined by those properties. Looked at in combination, they form a complex network of interrelated phenomena.
Stereoscopic depth perception is based on the principle of binocular vision and the cognitive process of stereopsis in which the brain estimates depth within the visual field based on the disparity of two slightly dissimilar images presented to the visual cortexes by both eyes. The amount of perceived depth is determined by the disparity level, within a range limit. Exceeding this limit leads to binocular rivalry, a phenomenon that occurs when two dissimilar images are presented simultaneously. The observer is only conscious of one of the two images at a time, one is dominant, the other is suppressed, every few seconds the perceptual dominance will switch.
The series challenges human perception by transforming images of a transient landscape into abstract shapes and movement into depth. Form, time and stereoscopic depth become variable properties in this visualisation. The project constitutes a novel visual framework for the study of visual perception with a focus on sensing depth through binocular vision in a dynamic constructed scene.
