This article is a reflection on the role of varied sensory inputs in human visual process. There’s some science, some art, some mental doodling represented. Bottom line is there are three primary input pathways to vision and we will revisit these in depth at the
Overall: Vision = Sight + Somatosensation + Vestibular Sense + Higher Cortical Functions + Reflex Functions
Primary Sensory Inputs to Vision: Sight + Somatosensation + Vestibular Sense
Sight – mostly the eyes but also internal elements that drive eye movement and attention.
Somatosensation (Somathesis) – Includes : ‘Touch’, nociception (pain), thermoreception (heat), proprioception (stretch), chemoreception (i.e. burns), mechanoreception (pressure). Provides sense of how body is positioned.
If one of these three is impacted, visual process will falter, fail. Eyes might be intact and in good shape, but if vestibular sense is diminished, basic scanning skills will be affected, for example.
We will come back to these ideas often during VRR.
