Human Factors aims to better integrate humans and systems to increase effectiveness and safety, and to reduce errors and accidents.
Sometimes, these systems can be simple, such as a human using a pen; and sometimes they can be much more complex, such as the systems in place to launch shuttles and rockets into orbit. One principle that is often used in our field is called “Affordance.”
Affordances are defined as a quality of an object or environment that makes it obvious what that object or environments purpose or function is.
Eyewitness testimony is often highly regarded by juries and those who write television crime dramas.
