Uncovering the secrets of the human body’s perception of touch

Scientific research has yielded deep understanding on the human senses of sight, hearing, smell, and taste. But knowledge about bodily perceptions of the sense of touch is still limited. For example, during a handshake, who is shaking whose hand? The answer to this question is just one of the multifaceted aspects of touch being studied by ‘haptics scientist’ Masashi Nakatani. “I am intrigued by human somatosensory (touch and body) perception and its utilization for positive psychological and cognitive effects in our daily lives,” says Nakatani, who commenced his research on the Shonan Fujisawa Campus (SFC), Keio University, in April 2017. “I started studying touch modality 16 years ago as an undergraduate. My doctorate was about human tactile perception for developing tactile displays that can provide information through the skin surface.” After his doctorate, Nakatani investigated touch receptors embedded in the skin in a dermatology laboratory and also worked in industry on developing tactile sensors for evaluating cosmetics.
