| My thesis focuses on the use of perceptual control theory to predict performance in a four-dimensional, pursuit tracking task. Shortcomings of behaviorism, cognitive plan models and coordinative structure theories are discussed, as well as how perceptual control theory resolves their shortcomings. The task was run on an IBM compatible computer, using a mouse and joystick. Perceptual control theory simulated performance of the participants by using four independent control system models. The correlation between the model simulations and persons' performance ranged from 0.91 to 0.99. Human factor aspects of the control devices are also investigated and recommendations toward improving the ergonomics of the devices and their interfaces are also discussed. Other results discussed include task switching between independent degrees of freedom. |
