Pointing and calling
Pointing and calling is a method in occupational safety for avoiding mistakes by pointing at important indicators and calling out the status. It is common in Japan and railways of Taiwan, it is also sometimes referred to by its Japanese terms, shisa kanko (指差喚呼), shisa kakunin kanko (指差確認喚呼) or yubisashi koshō (指差呼称). Making large gestures and speaking out the status helps keeping focus and attention. The method was first used by train drivers and is now commonly used in Japanese industry. It is not common in other countries, though it is used in the New York City Subway system. It is recommended by the Japan Industrial Safety and Health Association (JISHA, 中央労働災害防止協会).
The method originated in Japan in the early 1900s, with train drivers calling out the status of signals. The pointing was added a few decades later.

In NYC, subway conductors have to point at a black and white sign to prove that they're paying attention. They do it at every hour, at every stop. It's kind of silly, so we decided to make their day.
