When is the eyetracker active and ready to use?

When the icon for your eyetracker within the Lexplore Testing Application is green it is all set to be used for assessments.

You can perform assessments when the icons for audio, external monitor, and eyetracker are green.

In the top right corner of the Testing Application, you will find the eyetracker icon. If the icon is green, this signals that everything is running correctly and it is ready to use. If it is red, this indicates that you need to make some adjustments in order for it to work.
