The process further includes receiving physiological sensor signals from the physiological sensors and preparing the physiological sensor signals for further processing by removing at least some of the noise and artifacts and doing data augmentation. The process also includes producing an emotion-predictive signal by utilizing an emotion database. The emotion database has been developed based on empirical data from physiological sensors with known emotional states. The method also includes delivering the emotion-predictive signal to a virtual-reality system or other computer-implemented system. Other methods and systems are presented."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Human-computer interface systems and methods","description":"In one instance, a process for predicting and using emotions of a user in a virtual reality environment includes applying a plurality of physiological sensors to a user.
