Claudio Feliciani, co-winner of the 2021 Ig Nobel Prize for kinetics, is the subject of an NHK-World TV special, which you can watch online. NHK explains:
Claudio Feliciani is a Swiss-Italian scientist whose main interest is the movement of crowds. He worked alongside 3 Japanese scientists on a study that examined why people bump into each other when some of them are looking at a smartphone. It won an Ig Nobel Prize, which honors research that first makes you laugh, then makes you think. In a Japanophiles interview, Feliciani tells Peter Barakan how he ended up in Japan, and why he finds crowds so fascinating.
