Okay, kiddo, do you know what interaction flow is? It's like how you talk to people and do things with them. Do you remember playing a game of tag with your friends? That's interaction flow!
Now, sometimes, grown-ups need to do things with computers or software, and they need to plan out how those things will work. That's where the interaction flow modeling language comes in.
It's like making a map of how people and computers will talk to each other. Just like how you might draw a map of your neighborhood with different paths and places, the interaction flow modeling language lets people draw out what they want the computer or software to do with pictures and symbols.
By drawing out this map, people can see if their idea for how the computer or software will work, makes sense. It's like practicing before you play tag, you want to make sure everyone knows the rules before you start playing.
So, the interaction flow modeling language helps grown-ups plan how the computer and people will work together to get things done, and make sure everyone understands what they need to do.
