➀ Professor Mario Nadj at the University of Duisburg-Essen has developed a method using machine learning and electrocardiogram sensors to predict and enhance the 'flow' state, a phase of deep concentration.
➁ This method can predict the flow state almost in real-time, allowing for uninterrupted determination unlike traditional methods that rely on self-reports.
➂ The research aims to reduce interruptions and improve productivity, with potential applications in both professional and musical settings.
