What do people want to touch in their daily lives? We clarified the desire for touch in their daily lives by collecting and analyzing a huge amount of text data that people tweeted "want to touch" on Twitter. We revealed the relationship between the body part that the people want to touch and the way they want to touch it in their daily lives. Also, we revealed the effects of the COVID-19 pandemic on touching desires. Specifically, we observed the "skin hunger", or touch desire for animate' warm skin, and variation of touch avoidance toward inanimate targets such as doorknobs. It is expected that our findings can contribute to problems in broad areas such as elucidating the mechanism of touch desire in their daily lives, designing products that consumers really want to touch, and monitoring the impact of actual social problems such as the spread of infection on people's awareness.
