Pointing and calling
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 especially 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); in Mainland Chinese and Taiwanese railways, where it is called 指差呼唤; 指差確認 (zhǐchā hūhuàn); and in Indonesian railways, where it is known as tunjuk-sebut.
