Apparatus and method of monitoring a subject and providing feedback thereto

A method, comprising:

• directing light having a first wavelength toward a subject;
• directing light having a second wavelength toward the subject, wherein the first wavelength does not equal the second wavelength;
• capturing a first image of light reflected by the subject having the first wavelength;
• capturing a second image of light reflected by the subject having the second wavelength;
• subtracting a signal indicative of the first image from a signal indicative of the second image and producing a third signal;
• and
• providing informational content to the subject in response to the third signal.

An apparatus, comprising:

• an interface for receiving a signal associated with a subject's state of drowsiness;
• and
• a feedback device in communication with the interface for providing informational content to the subject in response to the signal;
• wherein the informational content includes information associated with the subject's behavior while in the state of drowsiness;
• and
• wherein the informational content is presented in a form that facilitates the subject's decision making process.
