Summarize this article for a 10 years old
Pointing and calling is a method in occupational safety for avoiding mistakes by pointing at important indicators and verbally calling out their status. It is particularly common on Japanese railways, where it is referred to as shisa kanko (指差喚呼), shisa kakunin kanko (指差確認喚呼) or yubisashi koshō (指差呼称); and in Chinese railways, where it is called "指差呼唤" (Pinyin: zhǐchā hūhuàn). Gesturing at and verbalizing these indicators helps with focus. 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, Toronto's TTC subway and GO Transit and many systems built in Chinese standards, for example Addis Ababa-Djibouti Railway. It is recommended by the Japan Industrial Safety and Health Association [ja] (JISHA, 中央労働災害防止協会),[1][2] and a part of railway management regulations in China.[3]
Pointing and calling requires co-action and co-reaction among the operator's brain, eyes, hands, mouth, and ears.
