Goal-oriented
human saccades were recorded under double-step paradigm. The stimuli consisted
of either visual or auditory-visual bi-sensory targets. Eye movement data were analyzed based on a 3rd-order linear horizontal saccadic eye movement model,where the inputs to the muscle were agonist and antagonist active-state
tensions that were described by pulse-slide-step wave forms with a post
inhibitory rebound burst (PIRB) based on a time optimal controller. Parameter
estimations were calculated using the system identification technique for
saccade parameters and neural inputs. Saccade amplitude transition function
(ATF) and response latency indicated the saccade programming mechanism. The
responses were affected by when the second peripheral target was presented.
