What is the eye reference point?

According to the SAE Dictionary of Aerospace Engineering, the Design Eye Position is defined as “a point fixed in relation to the aircraft structure at which the midpoint of the pilot’s eyes should be located.” The Aeronautical Information Manual (Airmanship 4.12) goes on to highlight that the pilot should also be …

What is eye datum?

The design eye position, also known as eye datum or design eye reference point (DERP) is one of the key aspects of cockpit design. It is used to size the cockpit windows and defne the location of all the controls, displays and instruments.

What is Design Eye Position (DEP)?

The Design Eye Position represents the ideal but notional location of the operator’s view and is usually expressed as a monocular point midway between the pupils of the average user. The DEP may also allow for a standardisation of monocular and binocular “Field of View” and may be integrated into the CAD/CAM design system used…

What is a design eye reference point (Derp)?

The design of the flight deck of a modern commercial airliner starts with the concept of the pilot’s “design eye reference point (DERP).” This point allows for a finite reference enabling the precise determination of geometric entities that define the layout of the cockpit.

How do eye-trackers measure eye-in-head angles?

Eye-trackers necessarily measure the rotation of the eye with respect to some frame of reference. This is usually tied to the measuring system. Thus, if the measuring system is head-mounted, as with EOG or a video-based system mounted to a helmet, then eye-in-head angles are measured.

What is the direction of your eyes when you lie?
