The work detailed in this dissertation is on the head/eye control problem, which has been of interest to scientists since the 19th century. Some of the earlier work on this subject were done by prominent scientists such as F. Donders, J. Listing and H. von Helmholtz. In the recent decades, scientists such as D. Robinson, M. Ceylan, D. Tweed, J. Crawford, B. Glenn and T. Vilies, have done notable work on head/eye movement. This work is an extention of the work done by A. D. Polpitiya, W. P. Dayawansa, C. F. Martin and B. K. Ghosh. In this research we use a classical mechanics approach to study the head/eye movement problem. The head and the eye are modeled as spheres pivoted at the centers and their dynamics are studied under the constraints proposed by Donders and Listing. The eye movement, the head movement and the head/eye coordination problem are studied under two different control strategies; namely potential control and optimal control. The results are then compared with measured head/eye movement data from human subjects.
