| 发明名称 | Auditory event-related potential measurement system, auditory event-related potential measurement method, and computer program thereof | ||
| 摘要 | An auditory event-related potential measurement system includes: a video output section configured to present a video to a user; a measurement section configured to measure a user's electroencephalogram signal; a scheduling section configured to schedule 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; an auditory stimulation output section configured to present the auditory stimulation to the user at the scheduled timing; and a processing section configured to acquire, from the electroencephalogram signal, an event-related potential in a first time range as reckoned from a point in time at which the auditory stimulation is presented. When an amount of video luminance change exceeds a threshold value, the auditory stimulation is not presented during a second time range as reckoned from a point in time at which the threshold value is exceeded. | ||

| 主权项 | 1. An auditory event-related potential measurement system comprising: one or more memories; and circuitry which in operation is configured to: present a video to a user;measure an electroencephalogram signal of the user;schedule 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;present the auditory stimulation to the user at the scheduled timing; andacquire, from the electroencephalogram signal, an event-related potential in a first time range starting from a point in time at which the auditory stimulation is presented, whereinthe circuitry is configured to schedule the timing of presenting the auditory stimulation so that, when an amount of luminance change in the video exceeds a predetermined threshold value, the auditory stimulation is not presented during a second time range starting from a point in time at which the predetermined threshold value is exceeded. | ||
