1. A method, comprising:
receiving first image data from a first camera oriented in a first direction with a first field of view facing a user;
receiving second image data from a second camera oriented in a second direction different from the first direction, the second camera having a second field of view corresponding to a field of view of the user;
determining a set of regions of interest based on the second image data;
determining a gaze direction of the user based on the first image data; and
determining an attentiveness score based on correspondence between the set of regions of interest and the gaze direction, the attentiveness score indicating whether the gaze direction of the user corresponds to the set of regions of interest for at least a threshold amount of
time, wherein determining the attentiveness score further comprises determining missed regi ons of interest among the set of regions of interest, each of the missed regions of interest indi cating a region of interest to which the gaze direction of the user does not correspond for at least a threshold amount of time; and
performing an action to alert the user in response to the missed regions of interest being higher than a threshold number.
