Eyes are the window to the soul, eyes reveals thinking and feelings. University of South Australia, University of Stuttgart, Flinders University and the Max Planck Institute for Informatics in Germany, use state-of-the-art machine-learning algorithms to demonstrate a link between personality and eye movements.
The results show that people’s eye movements reveal whether people are sociable, conscientious or curious, with the algorithm software reliably recognising four of the Big Five personality traits: neuroticism, extroversion, agreeableness, and conscientiousness.
Researchers tracked the eye movements of different participants as they undertook everyday tasks around a university campus, and subsequently assessed their personality traits using questionnaires.
The study provides new links between previously under-investigated eye movements and personality traits and delivers important insights for emerging fields of social signal processing and social robotics. The research has tracked and measured the visual behaviour of people going about their everyday tasks, providing more natural responses.
