Railways in Japan developed a system called
shisa kanko, which translates as "point and call," to keep staff alert both mentally and physically and focussing on relevant items or procedures. It is as it says: pointing at important items and saying what they are, in the process of work. So a driver points at the instruments in the cabin or at signals or platforms, a conductor points at doors and passengers when dispatching a train, and so on. There's a video on Youtube with English subtitles (the staff are speaking Japanese, obviously).
