In the article, Eye movements lead to a transformation of the 3-D visual field, representing a complex rotation and scale transformation of the near extrapersonal space with a centre somewhere in the region of a hypothetical "cyclopean eye," when using a complex 3-D configuration of reference points in the presence of structural rich afterimage (rAI) of the entire visual scene. Experiments have revealed that this also leads in the recalculation of the observer's gaze direction coordinates, purely based on input information and independent of oculomotor and even proprioceptive efferent system signals. Under distinct sorts of eye motions, three types of rAI illusions are described. These events are thought to be the work of "contextually" independent Screen Constancy Mechanisms (SCM), which function at the hypothetical Constant Visual Screen (CVS) level, according to a model proposed after 1976. This level of the visual system can still be called "pseudo-sensory," as it occurs before the creation (appearance) of the object-structured visual field. Certain circumstances impacting the degree of afterimage structural "richness" have also been examined in tests.
