Spatial disorientation
Spatial Disorientation
Spatial disorientation (pronunciation: /ˈspeɪʃəl ˌdɪsɔːriːənˈteɪʃən/) is a condition in which an individual's perception of direction or location does not correspond with reality. This condition often affects individuals in situations where visual cues are limited or absent, such as pilots flying in poor visibility conditions.
Etymology
The term "spatial disorientation" is derived from the Latin words "spatium" meaning space, and "orientare" meaning to orient or align. It was first used in the context of aviation medicine to describe the confusion pilots experience when they lose visual references and have to rely on their body's sensory inputs to determine their position in space.
