Title:
INTENTION TRANSMISSION SUPPORT METHOD AND INTENTION TRANSMISSION SUPPORT SYSTEM
Document Type and Number:
Japanese Patent JP2016066287
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an intention transmission support method and an intention transmission support system capable of allowing intention indicated by a subject to be recognized by the outside highly correctly in a short time, without using an electroencephalogram where the brain activity is in a rest and relaxed state which causes the subject to feel exhausted.SOLUTION: An intention transmission support system includes: a step of setting auditory sense stimulus sounds; a step of associating each auditory sense stimulus sound with a mental activity image; a step of making a subject recall the mental activity image when hearing the auditory stimulus sound; a step of measuring electroencephalogram data; a step of generating a first time waveform including an event-related potential change and a second time waveform including a mental activity-related potential change, which are formed by filtering the electroencephalogram data at a predetermined frequency, and determining the intention on the basis of the first time waveform and the second time waveform.SELECTED DRAWING: Figure 1
