Abstract
The proposed system consists of a number of conventions which allow postures to be numerically defined and recorded. The analyst's task is then to establish: (1) the levels at which joints and limbs are located; (2) the body's base posture within X, Y, and Z coordinate planes; and (3) the direction and amount of movement within these planes. The total capability of movement is listed in a table, and illustrations show how the proposed conventions are to be applied. A “Posturegram” has been designed and two examples are shown. The recorded posture can subsequently be digitally encoded, transmitted, and reconstructed. Accuracy of the definition depends on the measurement techniques used by the analyst. The conventions are applicable to all human subjects, irrespective of individual proportions, and can be interpreted in any language without the use of pictures.
