title: EyeP: Eye_Behavior_Personality Dataset

description: Eye Behavior and Personality Traits Dataset Overview



This dataset contains detailed eye movement recordings collected using the Tobii Pro Fusion eye-tracker and Big Five personality scores. The data captures participants' visual behavior as they interacted with different on-screen stimuli. It is organized into two main files:



eye_movement.csv: raw gaze and movement data

area_of_interest.csv — Aggregated gaze metrics by Area of Interest (AOI)

personality.csv - Participant's Big Five personality traits scores

event.csv - Contains eye movement events






📁 eye_movement.csv


This file stores raw gaze data sampled at high frequency.
