Let an agent explain visual perception and its stages, relay research on colour, form, depth and motion perception with attribution, describe variations and deficiencies in neutral terms, and route personal vision concerns to eye care professionals.

Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain visual perception and its stages, relay research on colour, form, depth and motion perception with attribution, describe variations and deficiencies in neutral terms, and route personal vision concerns to eye care professionals.

The ability to interpret the environment through light detected by the eyes, involving the optics of the eye, photoreceptors, retinal processing and cortical analysis of colour, form, depth, motion and objects; visual perception is studied in neuroscience, psychology and vision science, varies between individuals in conditions such as colour vision deficiencies and motion blindness, and is the basis of reading, navigation and visual art.

What it is for: Interpreting the visual environment.

It can be explain stages and mechanisms; relay research with attribution; describe variations and deficiencies; route personal concerns to professionals.

Distinguishing features

Optical and neural stages

Constancies and illusions

Individual variation

Cross-disciplinary study

What it looks like

Not a visible object; the experience of seeing.

Physical character

visible wavelengths: about 380-750 nm

cone types in typical humans: 3 count

How it is recognised

Interpretation of light by eye and brain

Colour, form, depth, motion and object perception

Visual acuity is a measure; vision loss is a clinical condition; a skyline is a perceived scene, not perception

What the second pass must settle

  • Should colour vision deficiency be a separate primary entry?
  • How should vision science references be linked?
  • The registry entry has merged aliases naming deficiencies and a scene type; should they be split off?
