Geon is a term used in cognitive science and perceptual psychology to describe a basic unit of visual perception. Coined by psychologist Irving Biederman in 1987, it refers to a simple geometric structure that can be mentally represented and recognized independently. Geons are considered to be the building blocks of object recognition and are thought to play a crucial role in how the human brain processes and understands complex visual stimuli.
These basic elements of recognition are three-dimensional, view-invariant, volumetric shapes, which can be perceived and identified despite variations in size, position, orientation, or lighting conditions. Geons are characterized by their basic structure and specific properties such as corner-like features, curved edges, and straight lines. Examples of geons include simple shapes like cylinders, cubes, wedges, cones, and rectangles.
Research suggests that the human visual system is highly attuned to geons, allowing for quick and efficient object recognition. The brain can recognize and categorize objects by identifying the arrangement, relationships, and combinations of different geons that make up the object. This theory is known as Biederman's recognition-by-components theory.
In summary, geons are elementary three-dimensional geometric shapes that form the basis of object recognition. They are key units in our perceptual system that enable us to quickly and accurately identify and comprehend complex visual stimuli.
The word "Geon" does not have a well-established etymology as it is a term primarily used in science fiction, particularly in regard to hypothetical astronomical or astrophysical objects. It was popularized by physicist John Archibald Wheeler in the 1960s. The term "geon" itself is a combination of "geo-" prefix that means "Earth" or "ground" and the suffix "-on" which is commonly used to denote particles or objects in physics. Thus, "geon" can be thought of as representing a hypothetical object or particle associated with Earth or ground, although in the context of science fiction, it denotes a more abstract concept.
