Claim 0:
1. A mental state awareness system, comprising:
a non-invasive brain interface assembly configured for detecting brain activity of a user, the non-invasive brain interface assembly including:
a head-worn unit configured for being worn on a head of the user;
a plurality of magnetometers disposed in or on the head-worn unit and configured to detect magnetic fields, wherein a first one of the magnetometers is configured to operate in a first mode selected from a scalar mode and a vector mode, and a second one of the magnetometers is configured to operate in a spin exchange relaxation free (SERF) mode different from the first mode;
at least one magnetic field generator; and
a controller configured to control operational functions of the magnetometers, the controller further configured to:
(i) measure an ambient background magnetic field using the first magnetometer in the first mode;
(ii) generate, in response to the measurement of the ambient background magnetic field, a compensation field using the at least one magnetic field generator, wherein the compensation field reduces the ambient background magnetic field measured by the first magnetometer in the first mode;
(iii) measure a target magnetic field using the second magnetometer in the SERF mode; and
(iv) determine when the second magnetometer is not operating in the SERF mode and automatically performing steps (i) and (ii) again;

a database, server, or cloud storage structure configured to track the measured target magnetic field as well as tracked magnetic field data of a pool of users;
a processor configured to determine a mental state of the user, the determination based on a comparison of the tracked measured target magnetic field and the tracked magnetic field data of a pool of users; and
a biofeedback device configured to automatically provide biofeedback to the user indicative of the determined mental state of the user.
