I picked elevator for in depth observation. After I thought the process deeply, I found some improvement I could do. Therefore, I started observe it more.
Description: Elevators of Bobst library
There are total 8 doors and 4 at right side, 4 at left side.
We can see the changing number on the right side wall. If there is no movement, then no sign. In the contrast, if the number is changing, arrow appears; down arrow when decreasing number, up arrow when increasing.
There are two buttons in each side. People usually press upper button on the first floor, and lower button on higher floors. And then people wait for a while in a standing posture. If someone is waiting earlier than new comer then new comer doesn't press button; however, s/he sometimes press button.
Before opening door, red light is blinking and bell ringing. People move to the door
After door opens, some or no people come out of the door. Waiting people go inside to the door one after another. Usually, 1 or 3 people.
There are several buttons on front side of the box. Number is written on some of them. Other character can be seen on the button.
People press number-button one after another. People don't press button every time, but they always see the panel. However, if they seem like friends, one of them usually do that and another don't do that. After pressing the button, people step back from the panel. Last person sometimes presses triangle-button. After that door closes in several seconds.
The number at the top of the panel is increasing or decreasing, arrow sign appears.
In the box, people is standing and don't move so much. Staring at the top of the panel(increasing/decreasing number) or talking with other people.
The box stops at the same number which is pressed by user. Door opens, bell rings. Person who pressed that number-button walk out of the box. Sometimes other people follows. Door closes. Sometimes nobody walk out.

* difference from bobst.
- people don't know whether it is going up or down so that usually ask people inside
- (4th floor to down) people wait it but it sometimes turns out fully occupied.
- (lobby) if left box is full and right box is coming down, people wait a while to press button before left one starts |
