Joe, where the observer is and the relative state of motion of observer and information source/s (object/s) affects what information is received, when, and so what information can be processed into the product. The information is not directly experienced but the product is experienced. The information is analysed, (for example lines are identified), and there is association with knowledge from prior experience or learning that allows object recognition and activation of relevant memories. By information, as we are talking about sight, I mean the frequency and intensity of em radiation. Surfaces do emit/reflect em radiation but because we (indirectly) see those surfaces via the em radiation received and processed it does not mean that only surfaces exist externally. Sonar, x ray and translucent and transparent objects let us know that there is more than just surface. As your model relies upon the eye, it would be good for you to research how the eye functions and vision occurs. Even with functioning eyes a person can be blind, as the optic nerve and parts of the brain are also involved in sight. Interestingly there is also something called blindsight. With that condition a person has a functioning eyes and optic nerve but specific damage to the visual cortex. Despite having visual knowledge they lack conscious awareness of seeing.
