Representation of Man Using CAD Technology: User Beware
In workplace design, the ergonomist aims to optimize worker comfort, safety and performance. To do this, he must consider relationships between the operator and his work, the work environment, and the equipment used. Anthropometry, the scientific measurement of the human body, provides techniques which the ergonomist uses to estimate man’s reach, vision, body clearance and body posture within the workplace. For example, two-dimensional drawing board manikins, composed of articulated scale representations of body segments, are used to describe man in side view; and stick-figure manikins are used to provide reference loci from which reach distances, visual angles and eye positions can be calculated. Partial and whole-body manikins are used to convey more realistic likenesses of man by representing anatomical landmarks, body contours and segment masses.
