PROBLEM TO BE SOLVED: To provide a configuration to estimate a feeling or an impression that a subject may have against an arbitrary perceptual stimulus using brain activity information appearing when a plurality of predetermined perceptual stimuli having been labeled are given.SOLUTION: An estimation system includes: generation means of generating a similarity matrix representing similarities between pieces of brain activity information; determination means of calculating coordinates, corresponding to a plurality of perceptual stimuli, on a space of predetermined dimensions from similarity matrices generated for a plurality of subjects respectively, and determining, from coordinates on the space corresponding to a perceptual stimulation given a certain label among the plurality of perceptual stimuli and coordinates on the space corresponding to other perceptual stimuli, a discriminator for the label; and discrimination means of discriminating whether a perceptual stimulus of a discrimination object corresponds to the label related to the discriminator by applying brain activity information measured when each subject is given to a perceptual stimulus of the determination object to the determined discriminator.SELECTED DRAWING: Figure 1 |
