The AI that can predict your personality simply by looking into your eyes

This technology could be put in smartphones that understand and predict our behaviour, potentially offering personalised support. They could also be used by robot companions for older people, or in self-driving cars and interactive video games. Dr Loetscher says 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. 'And thanks to our machine-learning approach, we not only validate the role of personality in explaining eye movement in everyday life, but also reveal new eye movement characteristics as predictors of personality traits.' 'Personality traits characterise an individual's patterns of behaviour, thinking, and feeling', researchers wrote previously in their paper published in Frontiers in Human Neuroscience. 'Studies reporting relationships between personality traits and eye movements suggest that people with similar traits tend to move their eyes in similar ways.' Researchers found that people who were neurotic usually blinked faster while people who were open to new experiences moved their eyes more from side-to-side. People who had high levels of conscientiousness had greater fluctuations in their pupil size. Optimists spent less time looking at negative emotional stimuli (such as image of skin cancer) than people who were pessimistic.
