Human Factors

Injury producing accidents involve an interaction between humans and physical, inanimate objects, or between humans and animals. The physical, inanimate world is usually the focus because the physical events can be modeled reasonably accurately by applying the laws and concepts of physics.

The human aspects are all too often ignored, other than possibly a casual mention of  “an accepted Perception – Reaction time” which may be grossly in error for a particular event. In part ignoring the human elements is often due to the fact that many, if not most, aspects of the human factors are “fuzzy” rather than clearly mathematically definable. However, to ignore the human factors involved is frequently to ignore the real crux of the case. 

HUMAN FACTORS are those aspects which describe the aspects of a human being, human experience, and human behavior.
