Vitalimetrics-based methods, devices and systems for health/lifestyle maintenance and improvement

1. A method of symmetric health state determination, monitoring, and intervention, comprising:

measuring one or more symmetric vital signs of a subject by using a symmetric vital sign measuring device, wherein said symmetric vital sign measuring device comprises:

at least one pair of sensors for measuring at least one vital sign as input for computing a symmetric vital sign value;

a processing unit capable of continuously receiving sensor inputs and configured to perform the steps of:

computing a time series of the symmetric vital sign values; and

determining a vitality state vector in a multidimensional hyperspace by taking the symmetric vital signs as state variables for the vector, wherein the values of symmetric vital signs are computed by taking the difference between a pair of vital sign values from a pair of symmetric counter-part locations on the subject's body;

a display unit for displaying the symmetric vital sign values and a representation of the vitality state vector,

wherein said sensors and display unit are operatively linked to the processing unit; and

determining a vitality state for the subject based on the symmetric vital signs.

2. The method of claim 1 , wherein said at least one vital sign measured by the sensors is body temperature.

3. The method of claim 1 , wherein said at least one vital sign measured by the sensors are selected from the group consisting of: body temperature, blood pressure, pulse rate, and a combination thereof, and wherein all vital signs are measured concurrently by the same symmetric vital sign measuring device.

4. The method of claim 1 , wherein said step of determining a vitality state comprises:

assigning a state of left-hot/right-cold when the symmetric vital sign has a positive value, and a state of left-cold/right-hot when the symmetric vital sign has a negative value.

5. The method of claim 4 , further comprising:

prescribing a health intervention regimen according to the vitality state of the subject, wherein said intervention regimen is selected from the group consisting of diet, exercise, living environment, and a combination thereof.

at least one pair of sensors configured to measure one or more type(s) of vital signs concurrently from symmetric counter-parts of a subject's body; and

a processing unit configured to continuously receiving sensor inputs from said sensors, and performing the steps of

computing a symmetric vital sign value for each type of vital sign by taking the difference between the vital sign values from a pair of vital sign measurements measured concurrently at symmetric counter-parts of the subject's body;

determining a vitality state vector in a multidimensional hyperspace by taking the symmetric vital signs as state variables for the vector, and

outputting a time series for each type of symmetric vital sign; and

a displaying unit for displaying the symmetric vital sign values and a representation of the vitality state vector.
