Apparatus and method of monitoring a subject and providing feedback thereto
First Claim
1. A device for monitoring a subject who is driving a vehicle and providing feedback thereto, comprising:
- a source of light having first and second wavelengths wherein the first wavelength does not equal the second wavelength;
at least one image sensor producing a first signal indicative of reflected light having the first wavelength and a second signal indicative of reflected light having the second wavelength;
a controller receiving the first and second signals and producing a third signal indicative of the first signal subtracted from the second signal such that the third signal is indicative of whether the subject is driving the vehicle while in a state of drowsiness; and
an interface in communication with the controller providing informational content to the subject in response to the third signal, wherein the informational content includes a distance driven by the subject while driving the vehicle in the state of drowsiness.

Abstract
A device and method for monitoring a subject and providing feedback back to the subject that is pertinent to a behavior of the subject. The device includes a source of light having first and second wavelengths wherein the first wavelength does not equal the second wavelength; at least one image sensor producing a first signal indicative of reflected light having the first wavelength and a second signal indicative of reflected light having the second wavelength; a controller receiving the first and second signals and producing a third signal indicative of the first signal subtracted from the second signal; and an interface in communication with the controller providing informational content to the subject in response to the third signal, wherein the informational content is associated with a behavior of the subject. The method includes 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.
