Why is NUIA not working?

This could have different causes. First make sure that the following points have been checked:

  • Is NUIA up and running? (Green icon in the task bar)
  • Is the Eye Tracker switched on/plugged?
  • Is your Eye Tracker locked to the magnetic strip and properly mounted?
  • Can the Eye Tracker recognize your eyes without any problems?
  • Is your eye tracker mounted on your monitor where you want to use NUIA?

If all of the above settings are correct and you still have the problem, try identifying your problem in the following examples:


Quick Click does not appear where my gaze is

If the Quick Click doesn't appear at your viewpoint, but is shifted, your Eye Tracker does not record your gaze data precisely.

What can you do?

  • Improve your calibration
  • Check your eye tracker profile (don't forget to create two different profiles for contact lenses or glasses)

NUIA overlays appear somewhere else

The best way to test this case is to activate your visual NUIA viewpoint (NUIA Tray Menu < Show my gaze) and look at clickable areas.

gaze point

If the rectangular blue borders appear offset around the clickable areas, your screen for NUIA is scaled incorrectly. The problem can be solved by exiting and restarting NUIA.


If these problems do not apply to yours, please do not hesitate to contact us.
