Abstract : An investigation of the extension of a continuous attention pilot model describing function to a sampling environment through the use of two tasks was undertaken. Three different transfer functions were used as controlled elements in a compensatory tracking task. The technique of electro-oculography was used to monitor eye movements. Performance of the pilots was compared to the continuous attention pilot model with the effective time delay of the model varied to match the performance of the subject. This yielded an increased time delay factor which could be translated into a regression of the error signal bandwidth. The actual error signal bandwidth was determined and comparisons were made. Other parameters were compared with theoretical developments which indicate that sampling should result in an additional time delay to the basic pilot model. Quite good agreement was obtained, and the theory which predicts an additional time delay factor to be added to the pilot model describing function is substantiated. Additionally, a method for predicting performance is outlined. Workload measurement techniques were investigated, and a proposed measure of workload as mean dwell time divided by mean sample time was verified. (Author)
