Atari Games Challenge Pilot Dataset

Dataset: Atari Games Challenge Pilot Study Overview The Atari Games Challenge Pilot Study dataset is a multimodal dataset designed for exploring difficulty in the field of games research. It captures dynamic human interactions through electroencephalography (EEG), eye-tracking, realtime gameplay and posterior affect surveys, enabling the study of player experience through multiple views. The dataset comprises 3 games with 3 different difficulties, 19 participants, and 76 trials. Dataset Structure The dataset follows the Brain Imaging Data Structure (BIDS) format and consists of the following components: Root Folder: sub-* : Individual subject folders (e.g., sub-P001, sub-P002, sub-P003) dataset_description.json: General dataset metadata participants.tsv: Participant demographics and attributes README.md: This documentation file Subject Folders (sub-): Each subject folder contains: Behavioral Data (beh/): Physiological recordings (eye tracking,game session stimuli and posterior surveys) in JSON and TSV formats. EEG Data (eeg/): EEG recordings in .edf and corresponding metadata in .json. Data Modalities and Channels 1. Eye Tracking Data Channels: 16 (fixation points, left/right eye gaze coordinates, gaze validity) Sampling Rate: 256 Hz Trials: 76 File Example: sub-_task-tutorial_run-0_recording-gaze_physio.tsv 2. Pupil Data Channels: 21 (pupil diameter, eye position, pupil validity flags) Sampling Rate: 256 Hz Trials: 76 File Example: sub-_task-tutorial_run-0_recording-pupil_physio.tsv.gz 6. EEG Data Channels: 63 (EEG electrodes following the 10-20 placement scheme) Sampling Rate: 256 Hz Reference: Left earlobe Trials: 5632 File Example: sub-_task-tutorial_run-0_eeg.edf 7. Gameplay Data Channels:  128 (RAM bits which represent a specific parameter or value in the specific game played) Sampling Rate: 30 Hz Trials: 76 File Example: sub-_task-tutorial_run-0_recording-atari_physio.tsv.gz 8. Self-Report Survey Channels:  10 (Constructs related to the PXI survey) Trials: 57 File Example: sub-_task-pxi_run-0_beh.tsv Experimental Setup Participants engaged in a 4 Game play sessions (1 tutorial, 3 game) of 3 Atari 2600 games while Physiological responses were recorded. Inmediatly after every game finished, participants would answer an Survey Self-reporting the overall experience with it. The dataset enables the study of difficulty in games from two main perspectives: Objective and Subjective Game Difficulty, which can be mixed in order to get a full view of a player's experience   Usage Notes The dataset is formatted in ASCII/UTF-8 encoding. Each modality is stored in JSON, TSV, or EDF format as per BIDS standards. Researchers should cite this dataset appropriately in publications. Applications This Dataset is well-suited for research in: Player Modelling User Experience Human-Agent Interaction Multimodal Signal Processing Neuroscience and Cognitive Modeling Acknowledgments This dataset was collected with the support of brAIn lab, IT University of Copenhagen. Special thanks to all participants and research staff involved in data collection.
