Eye Tracker Record Component

Please note: This is a new component, and is subject to change.

The eye-tracker record component provides a way to record eye movement data within an experiment. To do so, specify the starting time relative to the start of the routine (see start below) and a stop time (= duration in seconds). Before using the eye-tracking record component, you must specify your eye tracking device under experiment settings > Eyetracking. Here the available options are:

  • GazePoint

  • MouseGaze

  • SR Research Ltd (aka EyeLink)

  • Tobii Technology

If you are developing your eye-tracking paradigm out-of-lab we recommend using MouseGaze which will simulate eye movement responses through monitoring your mouse cursor and buttons to simulate movements and blinks.

The resulting eye-movement coordinates are stored and accessible through calling etRecord.pos where etRecord corresponds to the name of the eye-tracking record component, you can set something (e.g. a polygon) to be in the same location as the current “look” by setting the position field to :code:`etRecord.pos and setting the field to update on every frame When running an eye tracking study, you can optionally save the data in hdf5 format through selecting this option in the experiment settings > data tab.

Parameters

Basic

namestring

Everything in a PsychoPy® experiment needs a unique name. The name should contain only letters, numbers and underscores (no punctuation marks or spaces).

startfloat or integer

The time that the stimulus should first play. See Defining the onset/duration of components for details.

stop (duration):

The length of time (sec) to record for. An expected duration can be given for visualisation purposes. See Defining the onset/duration of components for details; note that only seconds are allowed.

Data

Save onset/offset times: bool

Whether to save the onset and offset times of the component.

Sync timing with screen refresh: bool

Whether to sync the start time of the component with the window refresh.
