The Difference in Movement of Experienced and in Experienced Persons in Japanese Bowing

Greeting is the basis of omotenashi, and one of the ways to greet is to bow. We conducted an experiment on the difference in maneuver between an experienced and inexperienced person and measuring the positions and timing of the bowing motion. The bow of the experienced person had a stable angle, with the shoulder angle (θ1) being around 180 degrees all three times; in other words the head was straight and the angle of the waist (θ2) was at around 20 degrees all three times. The transitions from the onset of the bow till the head was lowered and from the head beginning to rise until the end of the bow were about equal speed, and the speed of the head was relatively slow at -100∼100 (pixel/s). There is a case where the θ1 and θ2 of the bow of the inexperienced persons both with the Japanese persons and Thai persons are synchronized, and the case where the neck is bent before the movement of bending the waist. With the Thai person, the θ2 was very deep and the movement speed was very fast. The difference in the experiences has more dispersion. Regardless of nationality, in the situation of no previous instruction, it is very difficult to express the gentel and slow motion of bowing.
