Use Case based on Activity Diagram

Some background first.

Activity & Use Case Diagrams usually depict behaviour. Activity Diagrams usually describe a process (or a linked sequence of activities). Yours doesn't really do that. That's OK - as long as the diagram works for you that's fine.

It's also normal to design an Activity Diagram as the process to realise a Use Case. You're asking to go the other way. Again, not conventional - but not impossible.

Use Cases are normally written as verb statements and describe actions a User would want to perform (e.g. "purchase book", "checkout"). Yours are nouns.

OK - so to your question.

Identifying the Use Cases involves asking the question: "What can Users do?". Looking at your Activity Diagram, I'd guess the Use Cases would be something like:

  • Take a Picture [with Camera]
  • View Photos
  • View Map
  • View Current Location on Map

Each of those would be a Use Case. There are probably others (what can a User do with Favourites?) but that should give you the idea.

hth.
