| Outline of Final Research Achievements |
Invisible visual stimuli were created by inserting a frame to a moving picture, which was switched at a fast frame rate and presented to 20 experimental subjects. Their brain waves were measured and their alpha-band spectra were used as individual features. The verification rate using Euclidian distance matching was approximately 60%.
Inaudible auditory stimuli were created by extracting supersonic sounds from high-resolution sounds and they were presented to 10 experimental subjects. Their brain waves were measured and their logarithmic brain-spectra were used as individual features. The verification rate using Support Vector Machine was approximately 77%.
