Title:
PSYCHOLOGICAL STATE MEASURING DEVICE
Document Type and Number:
Japanese Patent JP3142376
Kind Code:
B2
Abstract:
PURPOSE: To provide a psychological state measuring device for judging the psychological state of a testee by emitting a light into the body of the testee, and measuring and analyzing the time change of oxygen concentration in the body on the basis of the time change of the transmitted light.
CONSTITUTION: A multidimensional oxygen concentration measuring part 1 has a light emitting part 2 and light receiving part 3 having a plurality of measuring channels and emitting and receiving the light of a specified wavelength, a signal processing part 4 and a memory 6. It emits a light into the body of a testee and measures the time change of oxygen concentration in the body on the basis of the time change of the transmitted light. A Fourier transforming part 7 conducts the Fourier transforming processing of the time change of oxygen concentration, thereby determining the spectrum distribution to frequency, which is then stored in a memory part 8. Successively, a judging part 9 extracts the characteristic on the basis of the envelop of the spectrum distribution and compares the characteristic-extracted data with a correlation data determined on the basis of the envelop of the spectrum distribution of oxygen concentration change to a preset psychological state, thereby judging the psychological state.
