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 China. It is 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 recommended by the Japan Industrial Safety and Health Association (JISHA, 中央労働災害防止協会)
