These commands are used to set tracker configuration. This should be done at the start of each experiment, in case the default setting were modified by a previous experiment.
Controls which eye is recorded from in monocular mode
Arguments:
LEFT
or RIGHT
monocular eye selectionControls whether in monocular or binocular tracking mode .
Arguments:
YES
for binocular trackingNO
for monocular trackingCan be used to disable monitor marker LEDS, or to control antireflection option.
Arguments:
0
for normal operation4
for antireflection on-1
to turn off markersCan be used to disable filtering, reduces system delay by 4 msec. NEVER TURN OFF THE FILTER WHEN ANTIREFLECTION IS TURNED ON.
Arguments:
ON
enables filter (usual)OFF
disables filterCan be used to set level of filtering on the link and analog output, and on file data. An additional delay of 1 sample is added to link or analog data for each filter level. If an argument of <on> is used, link filter level is set to 1 to match EyeLink I delays. The file filter level is not changed unless two arguments are supplied. The default file filter level is 2.
Arguments:
0
or OFF
disables link filter1
or ON
sets filter to 1 (moderate filtering, 1 sample delay)2
applies an extra level of filtering (2 sample delay).Arguments:
YES
to convert pupil area to diameterNO
to output pupil area datasimulate_head_camera = <YES or NO> Can be used to turn off head tracking if not used. Do this before calibration
Arguments:
YES
to disable head trackingNO
to enable head trackingUsed to compute correct visual angles and velocities when head tracking not used.
Arguments:
<mm>
: simulated distance from display to participant in millimeters.
