To set up the eye-tracker for first use follow the instructions below. Make sure you are not electrically charged. If possible ground yourself. Do not walk away during setup.

For a fixed setup you should go through this once. If many people have access to the device it is recommended to regularly check the camera’s focal ratio and focus distance (points 3 and 10).

  1. Install the eye-tracker software as described in Installing the user application suite.

  2. Mount the eye-tracker onto the stand. Use the highest position.

  3. Check if the focal ratio (f-number) of the camera lens is set correctly. For the R1 (16mm lens) it should be 2.0. For the R2 (25mm lens) it should be 2.2.

  4. Remove the camera lens cap if applicable. Take care not to touch the glass of the filter screwed into the lens.

  5. Connect the Micro-B connector of the provided USB-cable to the camera.

  6. Connect the other side of the USB-cable to a USB-3.0 port on to the computer. A USB-3.0 port is usually blue colored or has a SuperSpeed logo.

  7. Connect the barrel jack of the power supply to the eye-tracker and insert the power plug into the wall socket.

  8. Start the eyevec-control application and go to the Setup page.

  9. Check and adjust the eye-tracker position so it corresponds with the dimensional drawing. Horizontally the center of the eye-tracker should roughly align with the center of your face.

  10. The focus ring of the camera lens should be adjusted to get a sharp image at the desired focus distance. There are a few options to do this. First loosen the camera focus ring fixation screw.

    1. For a rough focus adjustment hold your head at the appropriate distance from the eye-tracker (ask someone to measure the distance from the orange line on the lens to your eyes) and adjust the focus ring. The bright green bars below the eye-boxes should be as small as possible. Then gently tighten the focus ring fixation screw.

    2. For a quick adjustment of the focus distance using a DIY focus calibration stick follow the instructions in Quick camera focus distance adjustment.

    3. For a proper focus calibration (recommended) follow the instructions in Calibrating camera focus distance.

Once the focus distance has been calibrated don’t be tempted to adjust the focus ring if for some participant the image seems out of focus. Just move the participant’s chair.
