Gaze on Target Dataset

GAze on TArget Dataset


GAze on TArget (GATA) dataset is a large-scale annotated gaze dataset, tailored for training deep learning architectures. It was created following the “target search” paradigm where subjects were asked to visually search for a specific object class. Forty eight different subjects participated in the recording procedure using myGaze capturing sensor.

  • The introduced dataset contains about 120.000 gaze annotated images.
  • Based on the MSCOCO 2014 database.
  • 80 object classes.
  • 48 subjects, 41 males – 7 females, ages in the range 22-45.
  • 238 experimental sessions – 20 minutes each.
  • Each experimental session consists of about 85 image-group sessions (sets of six images-sixie).
  • 20.000 image-group sessions in  total.

The gaze annotations are provided with the json file format using the following naming convention.


The first part (objectID) denotes the target object class id and the second part (imageID) the COCO image id respectively. Inside the json file gaze points annotations, time stamp and x,y coordinates, are included as presented below.


Relevance Object Assessment based on Gaze

The proposed dataset was utilized for building a deep learning model capable of predicting objects in an image as relevant or non-relevant, based on gaze, according to the users’ preferences. The proposed model is presented below:
