VIRTUAL MOVEMENT DEVICE, METHOD AND PROGRAM FOR FMRI ENVIRONMENT USING BIOSIGNAL

摘要

PROBLEM TO BE SOLVED: To remove a noise caused by a high magnetic field from a biosignal measured in an fMRI environment generating the high magnetic field, have adaptability to an individual difference and characteristics change of a user and use the biosignal measured in the fMRI environment.

SOLUTION: This virtual movement device for the fMRI environment comprises an input part of the biosignal; a measuring part removing noise components after transmitting the biosignal, which is measured under the fMRI environment, outside the fMRI environment; a feature extracting part extracting a feature pattern from the measured biosignal; a movement intention estimating part estimating the movement and its force intended by the user from the feature pattern; a human body model part calculating movement locus based on the output of the movement intention estimating part; a feedback part presenting the user three-dimensional computer graphics expressing the states of the movement calculated by the human body model part and processing states of the respective parts under calculation; and a parameter storage part capable of storing and reading parameters to be used in the respective parts.
