Setup Instructions for Bright Light Illumination Mode
The Bright light illumination mode significantly improves the accuracy performance in the middle and
the bottom part of the screen of the TX300. The mode also has an impact on the tracking robustness
for subjects with large size pupils at close distance to the eye tracker or when performing recordings
in complete darkness (1 lux) unless the eye tracker is set to operate in 250 Hz or lower. For optimal
performance when using this mode it is recommended to set the eye tracker to operate in 250 Hz or
lower.
