I haven't studied this. After reading it, I was more interested and looked up some information. I hope I can give you some inspiration. . .

I take this word literally. .

Needless to say, gathering places are squares, snack streets, shopping malls and other places. .

Public information is some information that people need to know, such as going to the square, where to eat and where to buy clothes. Where is the toilet？ .

Interaction is the relationship between information. There are two kinds of relationships in this interaction: communication diagram and sequence diagram.

Communication refers to the role relationship that objects assume in interaction.

Order refers to the chronological order,

For example, in a library, there are interactive relationships such as librarian, new book storage, books and book numbers, among which there are both order and communication.

Terminal, ultimate terminal. For example, how many people go to eat and play in this gathering area today, and the comparison between today's number and tomorrow's number can also be an indicator.

The interactive terminal here should be like withdrawing money from a bank. When you first enter the door, there will be a number next to the machine for you to queue up with various accounts. This machine is equivalent to an interactive terminal. There is interaction between accounts. And the machine is also an interaction with you.

So I think it's your business to design similar machines in gathering areas like squares. My design suggestion is: square map, LCD touch screen manual operation, give some guidance. . When people go in for dinner, the snack bar will be displayed. Who has more people? Go shopping for clothes and go shopping. .

This estimate is a problem that most people will encounter, and it is very affordable. Ha ha. . Hope to adopt. . It's the first time to write so much. . .
