Auditory event-related potential measurement system, auditory event-related potential measurement method, and computer program thereof

An auditory event-related potential measurement method comprising the steps of:

• presenting a video to a user;
• measuring an electroencephalogram signal of the user;
• scheduling a timing of presenting an auditory stimulation so that the auditory stimulation is presented during a period in which the video is being presented to the user;
• presenting the auditory stimulation to the user at the scheduled timing;
• and
• from the electroencephalogram signal, acquiring an event-related potential in a first time range as reckoned from a point in time at which the auditory stimulation is presented, wherein,
• the scheduling step schedules the timing of presenting the auditory stimulation so that, when an amount of luminance change in the output video exceeds a predetermined threshold value, the auditory stimulation is not presented during a second time range as reckoned from a point in time at which the predetermined threshold value is exceeded.

A computer program stored on a non-transitory computer-readable medium, and to be executed by a computer provided in an auditory event-related potential measurement apparatus of an auditory event-related potential measurement system,

• the computer program causing the computer to execute the steps of:
• presenting a video to a user;
• acquiring an electroencephalogram signal of the user;
• scheduling a timing of presenting an auditory stimulation so that the auditory stimulation is presented during a period in which the video is being presented to the user;
• presenting the auditory stimulation to the user at the scheduled timing;
• and
• from the electroencephalogram signal, acquiring an event-related potential in a first time range as reckoned from a point in time at which the auditory stimulation is presented, wherein,
• the scheduling step schedules the timing of presenting the auditory stimulation so that, when an amount of luminance change in the output video exceeds a predetermined threshold value, the auditory stimulation is not presented during a second time range as reckoned from a point in time at which the predetermined threshold value is exceeded.

An auditory event-related potential measurement system comprising:

• an auditory stimulation scheduling section configured to schedule a timing of presenting an auditory stimulation so that the auditory stimulation is presented during a period in which a video is being presented to the user from a video output section;
• an auditory stimulation output section configured to present the auditory stimulation to the user at the scheduled timing;
• and
• an electroencephalogram processing section configured to acquire, from an electroencephalogram signal of the user measured by a biological signal measurement section, an event-related potential in a first time range as reckoned from a point in time at which the auditory stimulation is presented, wherein,
• the auditory stimulation scheduling section schedules the timing of presenting the auditory stimulation so that, when an amount of luminance change in the output video exceeds a predetermined threshold value, the auditory stimulation is not presented during a second time range as reckoned from a point in time at which the predetermined threshold value is exceeded.
