WebMay 5, 2024 · The looming eye panels were designed to be 200 mm wide as a result, to ensure that they could be detected from a distance of at least 50 m even during relatively low light levels. This looming eye design was incorporated into a three-dimensional rotating device consisting of two panels simulating an eye pattern ( figure 1 ). Looming is a term found in the study of perception, as it relates directly to psychology. Looming occurs when an object begins moving closer to the eye. As the resulting image becomes increasingly larger on the perceiver's retina, i.e., when an object looms, there is an automatic physiological response to perceive the object as an approaching object or surface, instead of one that is stationary or receding. Evidence indicates that looming perception is not limited to the visu…

Looming is the most noticeable and most often observed of these refraction phenomena. It is an abnormally large refraction of the object that increases the apparent elevation of the distant objects and sometimes allows an observer to see objects that are located below the horizon under normal conditions.
