Pointing and calling(指差確認喚呼、指差呼称)is a method in occupational safety for avoiding mistakes by pointing at important indicators and calling out the status. It is common in Japan. 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. A 1994 study by the Railway Technical Research Institute showed that pointing and calling reduced mistakes by almost 85 percent when doing a simple task.
