Patent Images
1. A method comprising:
- obtaining eye-tracking data characterizing pupil dilation and point of gaze for an individual;
associating the eye-tracking data with one or more of a plurality of predefined mental alertness levels, the predefined mental alertness levels being generated by providing a setting characterized by one or more mental alertness levels, subjecting one or more than one test individuals engaged in a task to the setting, obtaining eye-tracking data from the test individuals, performing calculations on the eye-tracking data, and modeling the eye-tracking data to describe the one or more mental alertness levels; and
identifying the associated predefined mental alertness level.

Abstract
A method for determining mental alertness level by monitoring point of gaze, pupillary movement, pupillary response, and other parameters in a subject performing a task, collecting the data in a database, analyzing the data in the database, and assigning the subject to a score indicating the subject'"'"'s particular mental alertness level in real time.
