Abstract
Two experiments employing tho Toronto Complex Coordinator (TCC) are reported which demonstrate that a consideration of control-display (C-D) linkages from the point of view of the operator yields information which is useful in predicting relative performance levels for various combinations of C-D linkages, locations of 13, and positions of the subject (S) relative to C and D. A method of describing tasks in terms of o C-.D-S matrix is described and illustrated with 10 such combinations. Experimental tests confirm the accuracy of predictions of relative performance levels made from entries in these matrices. It is also shown that the use of this form of task analysis may be extended to oilier tracking systems, such as the Two-Hand Coordinator, to predict accurately the optimal C-D linkage and location of the controls relative to S and D.
