Professor Masayuki Numao of the Institute of Scientific and Industrial Research, Osaka University, Professor Noriko Otani, Faculty of Media and Information Studies, Tokyo City University, Crimson Technology Inc., and the collaborative team of the Belgian research institute imec have newly developed a headphone type wireless brain wave sensor and prepared a song in advance. We have developed an artificial intelligence that automatically composes music based on the user's brain wave response to the problem.
"Brain management" that will be provided to society in the future is thought to lead to further activation of the brain by detecting the state of individual brain waves and providing means for activating the brain based on it. The use of music as a means of doing so is promising.However, the conventional music providing system only has an automatic composition system that requires to recommend songs similar to the songs that have been listened to in the past or specify the characteristics of the songs in detail, and can easily connect to the activation of the brain with music. It was difficult.
Therefore, by developing a brain wave sensor integrated with headphones this time, it becomes easier to collect brain wave data for songs, machine learning the relationship between the reaction to the collected songs and brain waves, and activating the user's mental state. It has become possible to easily generate the music of.The composition results are immediately arranged on the spot by Musical Instrument Digital Interface (MIDI) technology and reproduced with rich tones using a synthesizer.
The developed artificial intelligence will enable custom-made composition, making it easier to use music-based activation methods such as music therapy.In addition, by changing the composition while measuring the state of the brain in the field of music therapy, it becomes easier to analyze the effect of music stimulation, and by applying it to entertainment such as games and healthcare such as sports gyms. , It is also possible to utilize it as a music system with a higher degree of flexibility.
Furthermore, as one form of future social implementation, in the future, the individual's condition will be measured by brain waves at home, and based on the results, the individual's potential will be measured by using music stimuli that match the individual's condition. It is also expected to realize a system that can always be demonstrated.
