Calibration accuracy can be visualized with the Accuracy Visualizer plugin.For example: If during your calibration you only looked at markers or natural features (depending on your calibration choreography) that are in the left half, you will not have good accuracy in the right half. Any calibration is only accurate inside the field of view (in the world video) you have calibrated.Any monocular calibration is accurate only at its depth level relative to the eye (parallax error).Using the 3D Gaze Mapping you should achieve 1.5-2.5 deg of accuracy. With the 2D Gaze Mapping, you should easily be able to achieve tracking accuracy within the physiological limits (sub 1 deg visual degrees). Press c on your keyboard or click the blue circular C button in the left hand side of the world window to stop calibration.Repeat until you have covered the subject's field of view (generally about 9 points should suffice).Click on that point in the world window.Note: pick a salient feature in the environment. Ask the subject (the person wearing the Pupil headset) to look a point within their field of vision.

Press c on your keyboard or click the blue circular C button in the left hand side of the world window to start calibration.

Be aware that this is dependent on the brightness and therefore has a strong interaction with Video Source/Sensor Settings/Absolute Exposure Time.

Try to minimize the range so that the pupil is always fully covered while having as little leakage as possible outside of the pupil. The pixels considered for pupil detection are visualized in blue when in Algorithm Mode.

Intensity Range : Defines the minimum "darkness" of a pixel to be considered as the pupil.

Set the min and max values so the green circle (current pupil size) is within the min/max range for all eye movements. The green circle visualizes the current apparent pupil size.

Pupil Min/Max : In Algorithm Mode the two red circles represent the min and max pupil size settings.

The detector settings can be adjusted in the Pupil Detector 2D plugin.

For a better visualization of these settings, go to the General Settings menu of the eye windows and enable the Algorithm Mode view. Some settings of the 2D pupil detector can be adjusted to improve pupil detection.

Add your user to the plugdev group by executing the following command in the terminal:Īs a first step it is recommended to check the eye camera resolution as some parameters are resolution dependent.

Shut down Pupil Capture if it is still running.

If the cameras are listed as unknown and you are not able to access cameras in Pupil Capture.

This should install drivers automatically. Right click on pupil_capture.exe > Run as administrator.Unplug Pupil headset (if plugged in) and plug back in.

#SCREEN MARKER DRIVER#

For each Pupil Cam device (even hidden devices) click Uninstall and check the box agreeing to Delete the driver software for this device and press OK.Expand libUSBK Usb Devices, Cameras, and Imaging Devices categories.In Device Manager ( System > Device Manager).If that does not work, follow the troubleshooting steps below:

You should first try to run Pupil Capture as administrator (right click pupil_capture.exe > Run as administrator). This could mean that drivers were not automatically installed when you run Pupil Capture as administrator. If no headset is connected or Pupil Capture is unable to open capture devices it will simply display a gray screen. If you have a Pupil Core headset connected to your computer you will see videos displayed from your Pupil Core headset in the World and Eye windows. System plugins are loaded in the top and user added plugins are added below a horizontal separator.Īdd annotation (default keyboard shortcut)Ĭamera intrinsic estimation: Take snapshot of circle patternīy default Pupil Capture will use Local USB as the capture source.
