Spatial Disorientation

This document discusses spatial disorientation, which refers to the inability to correctly perceive one's orientation in three-dimensional space. It provides perspectives from several authors on maintaining spatial orientation on the ground versus in flight. Key factors that affect spatial orientation are discussed, such as vision, vestibular systems, and proprioception. The importance of visual references for spatial awareness is highlighted, especially when in motion. Experiments are referenced, and central versus peripheral vision are compared. Guidelines for visual references that help with spatial perception at different distances are provided. Examples of videos that demonstrate spatial disorientation factors are linked.

- 21. 10戒 (Visual References) ● Comparative size of known objects at different distances. ● Comparative form or shape of known objects at different distances. ● Relative velocity of images moving across the retina. Nearby objects are perceived as moving faster than distant objects. ● Interposition of known objects. One object placed in front of another is perceived as being closer to the observer. ● Varying texture or contrast of known objects at different distances. Object detail and contrast are lost with distance. ● Differences in illumination perspective of objects due to light and shadows. ● Differences in aerial perspective of visualized objects. More distant objects are seen as bluish and blurry.
