1. A method comprising:
at a device comprising a processor:
presenting content for a plurality of time segments to a user and obtaining physiological data associated with a gaze of the user;
determining a variability of a gaze characteristic for the plurality of time segments based on the obtained physiological data, wherein the variability of the gaze characteristic comprises a measurement of at least one of a range, a variance, and a standard deviation of the gaze characteristic over a time period, and wherein the variability of the gaze characteristic is classified based on comparing the variability of the gaze characteristic to a threshold;
determining that the user has a first attentive state during a first time segment of the plurality of time segments based on classifying the variability of the gaze characteristic of the user, wherein the first attentive state comprises a mind wandering state that includes a different stability of the variability of the gaze characteristic compared to a focused state; and
presenting feedback content for a second time segment in response to determining that the first attentive state differs from a second attentive state intended for the content, wherein the feedback content directs the user to modify a physiological action associated with the first attentive state, and wherein the second attentive state intended for the content comprises the focused state.
