Expressions based on physical movements such as ballroom dancing and hip-hop have been incorporated into school education and are highly evaluated for their effectiveness in preventing dementia. One reason is that it moves the body comfortably to the music. The other one is that it includes brain activity while communicating with others. In such a physical expression, the motor learning process has many individual differences and is unknown. In addition, the power of expression varies greatly depending on the current mental state. In this paper, we will ground linguistic knowledge structuring to various nonverbal data. We will show an example of ballroom dancing and challenge the collection and analysis of these implicit and unexplored data.
