Eyes are the window to the mind. A group of research reveals that your eyes may also be an indicator of your personality type. The researchers used state-of-the-art machine-learning algorithms to demonstrate a link between personality and eye movements.
The machine was developed by the University of South Australia in partnership with the University of Stuttgart, Flinders University and the Max Planck Institute for Informatics in Germany.
According to the findings, people's eye movements reveal whether they are sociable, conscientious or curious, with the algorithm software reliably recognising four of the Big Five personality traits: neuroticism, extroversion, agreeableness, and conscientiousness.
Eye movements of 42 participants were tracked as part of the study. Later, the personality traits were assessed using well-established 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 researchers said. "There's certainly the potential for these findings to improve human-machine interactions," they added.
"People are always looking for improved, personalised services. However, today's robots and computers are not socially aware, so they cannot adapt to non-verbal cues. "This research provides opportunities to develop robots and computers so that they can become more natural, and better at interpreting human social signals."
He said the findings also provide an important bridge between tightly-controlled laboratory studies and the study of natural eye movements in real-world environments. "This research has tracked and measured the visual behaviour of people going about their everyday tasks, providing more natural responses than if they were in a lab."
