✦ Synopsis

A deeper understanding was sought of the physiological mechanism by which a visual stimulus produces muscular movement of a human operator . The operator may be regarded as a type of control mechanism, and analysed on this basis, but the investigation is subject to peculiar difficulties not experienced in tests on inanimate machinery . Some of these difficulties and the nature of the apparatus best suited to the study are discussed . The reasons for selecting a compensatory task with a random input and a simple manual control are given, and the design and testing of the apparatus are briefly described .

Tests conducted on five operators who were undergoing a learning process are described, and on the basis of these an analogue for the human operator is suggested . It is considered that this analogue explains many of the unique phenomena associated with this study .

The subject of this work is the characterization of a fuzzy control operator model that can successfully emulate the functioning of a human control operator in a compensatory tracking loop on a real-time basis. After a learning period spent in the proximity of the real human operator being modelled,

Rational design of a process control system using an on-line computer requires a definition of the total control task and an allocation of function between the human operator and the machine. Both the nature of the total task and its subdivision depend very much on the process characteristics, which

## Abstract A study was undertaken to provide data on the three‐dimensional tracking pattern of the patella, relative to the femur, in human knee‐joint specimens. For this purpose, a highly accurate roentgen stereophotogrammetric analysis (RSA) method was applied. The three‐dimensional motion patte
