MODELING AND CONTROL OF 3D EYE MOVEMENT WITH MUSCULOTENDON DYNAMICS

摘要

Recent anatomical studies of extraocular muscles (EOM) demonstrate the stability of muscle paths. This is due to the fact that each rectus EOM passes through a pulley consisting of an encircling ring or sleeve of collagen. In this paper, the EOMs aremodeled using the Hill type musculotendon complex and the effect of extraocular pulleys are studied. The model proposed by Martin and Schovanec in 1999, for horizontal eye movement has been used as a basic starting point. The extraocular pulleys are thenintroduced and analyzed mainly to study how Listing's law is enforced and how it implements an oculomotor plant which appears commutative to the brain.
