Experimental Data of Infrared vs. Webcam Eye Tracking for User Behavior Mining: A Comparative Study

This archive contains the data used for the paper "Comparing Infrared and Webcam Eye Tracking for User Behavior Mining in Office Environment". It includes the raw recordings, the preprocessed and postprocessed data derived from those recordings, and the scenario definitions used in the experimental tasks. Folder structure 1) raw_data/This folder contains the original raw recordings collected for each study condition. The data are organized by scenario family and participant/session. - SQ1_static_form/ : static form-density tasks (low and high density)- SQ2_alternance/ : alternating button-selection task- SQ3_position/ : distance-based position tasks (50 cm, 70 cm, 90 cm)- SQ4_rpm/ : RPM-related task Inside each scenario folder, data are grouped by participant/session ( S1, S2, ... S10) and by device/software branch (Infrared Device Tobii Spark Pro and Webcam-based WebGazer.js). Each branch contains the original log files (gaze log and UI log) and associated extracted resources from the experiment. 2) preprocessed_data/This folder contains every gaze fixation corresponding to the user action. To obtain gaze fixations and assign every UI action their corresponding gaze fixations we used the open-source software tool "User Behaviour Gaze Integrator" https://github.com/RPA-US/ubgi. This software employs I-DT algorithm to obtain the gaze fixations. The output from this software is not yet the final analysis-ready outputs. The output is the data which we will process to obtain the aggregated features (e.g., match-fixations). 3) postprocessed_data/This folder contains the final analysis-ready CSV files used in the study. They are organized by participant/session and contain the aggregated features (e.g., match fixations) required for the metrics presented in the paper and the statistical analysis 4) test_cases_scenarios/This folder contains the scenarios of the different experimental test cases. These files document the structure of the tasks used in the study and help reproduce the experimental setup. Ethics Approval: The experimental protocol was conducted in accordance with the ethical standards of the University of Seville. The study design was reviewed to ensure the protection of participants' rights and safety in accordance with the institutional guidelines for human subjects research. Informed Consent: All participants were fully briefed on the study's objectives and the nature of the eye-tracking data being recorded (both infrared and webcam-based). Written informed consent was obtained from every participant before the start of the experimental sessions. Data Protection: Data collection and processing were performed in compliance with the Spanish Organic Law 3/2018 (LOPDGDD) and the General Data Protection Regulation (GDPR) EU 2016/679, ensuring the right to privacy and the non-traceability of personal identities. Data cleaning and anonymization- Sensitive textual content in typed text fields has been anonymized.- Screenshot images have been removed from the extracted raw data where applicable.- The dataset is intended for reproducibility and secondary analysis, while protecting participant privacy. Notes- The study uses two input methods: an infrared-based eye tracker (Tobii Pro Spark) and a webcam-based tracker (WebGazer.js).- The dataset includes recordings from 10 participants (S1-S10).- Scenario names correspond to the research sub-questions in the manuscript.
