Use Case: User uses input device

Question

I am creating a use case diagram for a scenario where a user uses various input devices (tablet, wireless pen, etc) to interact with a system. For that part, because users only interact with the system through devices, I currently have the diagram like this...

I know that devices and systems and such can be use case actors, but I have not seen this kind of diagram design before where one actor uses another to use services. Is this viable as a use case diagram?

Answer 1

I suggest to model do this by device1, do that by device1, do this by device2 etc. as separate use cases. For showing that they actually share some core behaviour, you can define abstract (parent) use cases for do this and do that and use generalization relationships.

This article and this article have have good explanations on the concept of generalization.
