Single Image Visual World
The purpose of this experiment is to record participant’s eye-movements while he/she is listening to a spoken utterance and looking at a screen displaying a semi-realistic scene. For each trial a scene is displayed and an utterance relating to the scene is played. Participant’s task is to carefully look and listen. Self-paced. Output: Eye-Tracking data as collected by the eye-tracker.
This implementation can be used with an EyeLink eye-tracker (default), a Tobii 1750 eye-tracker, or an SMI eyetracker. You can select the desired device by importing the appropriate module.
