If binocular recording is being performed, the average position of both The units are in the units in use by the ioHub Display This is the position on theĬalibrated 2D surface that the eye tracker is reporting as the currentĮye position. The getLastGazePosition method returns the most recent eye gaze Only one instance of EyeTracker can be created within an experiment.Īttempting to create > 1 instance will raise an exception. and theĬorresponding surface name data topics.only Internally, this mode is implemented by subscribing to the gaze.3d. The integration takes care of translating the spatial coordinates to PsychoPy Receive positional data in addition to the pupillometry data mentioned above.įor this to work, one has to setup Pupil Capture’s built-in AoI tracking systemĪnd perform a calibration for each subject. If the Pupillometry only setting is set to False, the integration will Internally, this is implemented by subscribing to the pupil. To receive gaze data in PsychoPy screen coordinates, see the Pupillometry+Gaze The advatage of this mode is that it does not requireĬalibrating the eye tracker or setting up AprilTag markers for the AoI tracking. ![]() pupil size, its location in eye cameraĬoordinates, etc. If the pupillometry_only setting is to True, the integration will only This class operates in two modes, depending on the pupillometry_only runtime For details, see this real-time time-sync tutorial. This stepĮffectively transforms time between the two softwares while taking the transmissionĭelay into account. ![]() The offset between their clocks and applies it to the incoming data. To synchronize time between Pupil Capture and PsychoPy, the integration estimates Uses ioHub’s polling method to process data from Pupil Capture’s Network API.

Screen-based coordinates, and this facilitates closed-loop analyses of gaze based on the Trackers employ cameras mounted on or near a computer monitor. Pupil Core differs from remote eye trackers often used with PsychoPy ®. As such, gaze can be analysed with the wearer looking and moving freely Pupil Core provides gaze data in its world camera’s field of view, regardless of the wearer’s Mounted on a wearable eyeglasses-like frame.
