4.9.3.2 Samples Recorded with the EyeLink Remote
Data files recorded using the EyeLink Remote have sixteen extra columns to
encode the target distance, position, and eye/target status information. The
first three columns are:
<target x>: X position of the target in camera coordinate. Returns
"MISSING_DATA" (-32768) if target is missing.
<target y>: Y position of the target.
<target distance>: Distance between the target and camera (in millimeters).
Returns "MISSING_DATA" (-32768) if target is missing.
The next thirteen fields represent warning messages for that sample relating to
the target and eye image processing.
"............." if no warning for target and eye image
first character is "M" if target is missing
second character is "A" if extreme target angle occurs
third character is "N" if target is near eye so that the target window and eye window overlap
fourth character is "C" if target is too close
fifth character is "F" if target is too far
sixth character is "T" if target is near top edge of the camera image
seventh character is "B" if target is near bottom edge of the camera image
eighth character is "L" if target is near left edge of the camera image
ninth character is "R" if target is near right edge of the camera image
tenth character is "T" if eye is near top edge of the camera image
eleventh character is "B" if eye is near bottom edge of the camera image
twelfth character is "L" if eye is near left edge of the camera image
thirteenth character is "R" if eye is near right edge of the camera image
