Management Of Physiological And Psychological State Of An Individual Using Images Biometric Analyzer
|

Abstract
|
A method ol determining the physiological reactivity ol an individual with respect to images, comprising: measuring at least one physiological parameter ol an individual during a baseline calm period ol time; measuring the said at least one physiological parameter ol said individual during a stress period ol time and a succeeding rest period ol time; dividing said measured data lor each ol said periods ol time into a plurality ol predetermined time segments; computing a histogram or Fourier analysis as appropriate on said predetermined time segments lor each said period ol time; standardizing said computed data; conducting a principal component analysis, a canonical discriminant analysis, or a neural network, on said data to establish a baseline calm or rest period set ol scores and a stress period set ol scores; measuring the said at least one physiological parameter ol said individual during an image presentation period ol time; repeating said time segmenting, said histogram or Fourier analysis, and said standardizing steps on said measured physiological data lor said image presentation period ol time; applying said vectors from said conducting step to said image data to produce an image set ol scores which are compared with said baseline and stress sets ol scores; and determining whether said presented image is activating, deactivating, or neutral based on said comparison.
