An augmented reality system and methods for improving augmented reality are presented herein. Such systems are configured to monitor the brain state of an individual and configured to create a feedback loop whereby the brain state of the individual modulates parameters of the augmented reality system, thereby changing the augmented reality presented to the individual and tailoring the augmented reality presented to the individual in real time to suit the particular needs of the individual at any particular moment in time. Also presented herein are methods designed to monitor the brain state of an individual and create a feedback loop whereby the brain state of the individual modulates parameters of the augmented reality system, thereby changing the augmented reality presented to the individual and tailoring the augmented reality presented to the individual in real time to suit the particular needs of the individual at any particular moment in time.
