Final answer:
A use case diagram is a visual representation of the different ways that actors interact with a system, and it can be used to represent the interactions between users and the AI technology in a web app for fitness.
Step-by-step explanation:
A use case diagram is a visual representation of the different ways that actors (users) interact with a system. In the case of your web app for fitness, the main actors would be the users and the AI technology. Here is how you could draw the use case diagram:
- Create a rectangle in the center of the diagram and write 'User' inside it.
- Draw arrows from the User rectangle to other rectangles representing the different use cases. Use cases could include 'Track exercise', 'Receive exercise reminders', and 'Get exercise advice'.
- Create another rectangle and write 'AI Technology' inside it.
- Draw arrows from the AI Technology rectangle to the use cases, representing its interactions with the users.
This use case diagram would visually represent how the users interact with the AI technology in your web app for fitness.
