Abstract

Described herein are stress detection systems and methods of using such systems.

Claims

1. A method for detecting stress in a subject, said method comprising:

said subject having a periorbital region;

optimizing the subject'"'"'s temperature range to resolve only temperatures outside said periorbital region;

identifying a limited temperature range to establish a baseline for thermal values tailored to the subject to enable visualization of thermal changes in the subject;

establishing thermal thresholds based on said baseline;

displaying breaches outside said thresholds;

displaying the temperature values of said breaches;

adjusting said limited temperature range based on the unique temperature characteristics of the subject;

displaying a spectrum of different colors corresponding respectively to specific narrow temperature variations in regions selected from the cheeks, ears, forehead and neck or a combination thereof;

displaying selected color variations based on an audio waveform of the subject;

displaying the color spectrum of a predetermined pixel in an infrared video display;

varying a timeline of the combined audio waveform and infrared video image;

comparing the colors of the audio waveform and the infrared video image of said pixel at a particular point in time; and

changing the audio waveform color to track the color variations of said pixel infrared video image.

2. The method claimed in claim 1, further comprising the step of providing a graphical user interface with a timeline control with which a user can select a point in a captured image to begin playing.

3. The method claimed in claim 1, further comprising the step of recording captured infrared and visible-light video images on a data storage medium.

4. The method claimed in claim 1, further comprising the step of receiving an audio signal from a microphone and playing the audio through a speaker.

5. The method claimed in claim 4, further comprising the step of displaying a graphical representation of the audio waveform in response to the audio signal.

6. The method claimed in claim 5, wherein said infrared video display comprises a center pixel and said method further comprising the step of displaying the graphical representation of the audio waveform in a color responsive to said center pixel of the displayed infrared video image.

7. The method claimed in claim 1, further comprising the step of interleaving data elements relating to a plurality of video images to form an interleaved data stream.
