Figure 2. Two methods for filtering saccade commands.

a) Eye position for a series of saccades. b) The saccade velocity, based on a). c) Filtering based on magnitude. This method uses Equation 15 to filter the velocity profile. This is the method adopted for all subsequent experiments. d) Filtering based on a change in position, where a change in position greater than 5 degree allows the subsequent velocity commands to pass through at a magnitude inversely proportional to the time elapsed after a movement.
