Fruit emotional distress object is picture stimulation, can select band to be in a bad mood the picture of label from picture library, for example, " fearing in training
Fear " mood when, can from selected in picture library mood label for the plurality of pictures of " fear " to user in terms of, see mood in user
When label is the picture of " fear ", the brain wave (one section here can be one section of duration, such as 5 seconds) of one section of user of acquisition,
Then brain wave that every pictures are corresponded to acquisition is fitted, and fits " fear " corresponding brain wave template.For example,
It can be the terrified picture screened on network that mood label, which is the picture of " fear ", in picture library.
If emotional distress object is voice stimulation, band can be selected to be in a bad mood the sound bite of label from sound bank,
For example, in training " calmness " mood, multiple sound bites that mood label is " calmness " can be selected to use from sound bank
Family is seen, when user hears that mood label is the sound bite of " calmness ", the brain wave of one section of user is acquired, then by each language
The brain wave that tablet section corresponds to acquisition is fitted, and fits " calmness " corresponding brain wave template.For example, in sound bank
Mood label is the light music that the sound bite of " calmness " can more releive.
If emotional distress object is visual transmission, band can be selected to be in a bad mood the video clip of label from video library,
For example, in training " indignation " mood, multiple video clips that mood label is " indignation " can be selected to use from video library
Family is seen, when user hears that mood label is the video clip of " indignation ", is acquired the brain wave of one section of user, then will each be regarded
The brain wave that frequency segment corresponds to acquisition is fitted, and fits " indignation " corresponding brain wave template.For example, in video library
Mood label is that the video clip of " indignation " can be the video that some are easy to cause people's indignation.
