Abstract

A method, system, and computer program for non-invasively monitoring a physiological parameter and providing biofeedback. The method, system, and computer program provide for the non-invasive detection of a physiological parameter by detecting changes in color channel values of a user in a live video feed and presenting biofeedback to the user indicating the relative position of the physiological parameter to an optimal range.

First claim

Having thus described various embodiments of the invention, what is claimed as new and desired to be protected by Letters Patent includes the following:

1. A system for non-invasively monitoring a user under a workload, the system comprising:
at least one video camera within viewing range of the user and operably connected to a computing module, said at least one video camera oriented towards a user and operable to capture a live video feed of the user;
a computing module with a processor and a memory, said computing module being in communication with the at least one video camera and being configured to:
store optimal range values of a user, wherein the optimal range values are the lower and upper heart rate boundaries defined by a preferred physiological parameter determined by at least a user's resting heart rate and maximum heart rate;
receive the live video feed of the user from the at least one video camera;
detect changes in channel values extracted from the live video feed of the user; and
calculate a physiological parameter from the changes in channel values; and

a display monitor configured to display a biofeedback, wherein the biofeedback indicates at least where the physiological parameter value is relative to the optimal range values of the user.

2. The system of claim 1 , wherein the video camera is mounted in or on a housing and the display monitor is mounted in or on the housing.

3. The system of claim 2 , wherein the computing module is mounted within the housing.

4. The system of claim 1 , wherein the computing module is configured to automatically present on the display instructions to increase or decrease physical intensity levels based on the relative position of the physiological parameter to the optimal range of the user.

5. The system of claim 1 , wherein the biofeedback comprises at least one of heart rate, respiration rate, oxygen saturation, and lactate levels.

6. The system of claim 1 , wherein the at least one video camera is a mobile device camera.
