Abstract: The combination of artificial intelligence technology and brain-computer interface technology is a popular research and development direction. By analyzing patent data and the current status of industrial development,the development direction of brain-computer interface technology based on artificial intelligence is identified. A comparative study shows that Tianjin takes a leading position in this field. Several suggestions are put forward to provide ideas for Tianjin's industrial layout in this field.

Key words: brain-computer interface, artificial intelligence, patent analysis
