Visually goal-oriented saccades were recorded under the doublestep paradigm. Data were analysed to supply parameter estimates using the system identification technique for a 3rd-order linear horizontal saccadic eye movement model. Statistical analysis of an outsized human saccade data set provided reliable conclusions of the response properties. Saccade amplitude, latency, and intersaccade interval were discussed with time delay, indicating the parallel programming mechanism, during which two saccades to different targets might be programmed simultaneously. The results of neural input estimations suggested that the double-step visual targets may affect the synchronous firing of the saccade responsible neurons within the centre.
