Eye Monitor¶
Description¶
A filter that takes in an eye signal and outputs basic parameters, such as velocity, saccade state, etc.
Signature¶
filter/basic_eye_monitor
Required Parameters¶
eyeh_calibrated¶
Variable from which to read horizontal eye position
eyev_calibrated¶
Variable from which to read vertical eye position
eye_state¶
Variable in which to store computed eye state (0 for fixation, 1 for saccade)
width_samples¶
Number of samples to store in internal boxcar filters that are applied to computed velocity components
saccade_entry_speed¶
A computed eye speed greater than this speed denotes a saccade (units per second)
saccade_exit_speed¶
A computed eye speed less than or equal to this speed indicates fixation (units per second)
Optional Parameters¶
eye_velocity_h¶
Variable in which to store computed horizontal eye velocity (units per second)
eye_velocity_v¶
Variable in which to store computed vertical eye velocity (units per second)
