d. Use Cases

The Use Case is a step-by-step interaction description between one or more personas and the system. In this case it is between the PwD, the care taker and the dogg0. It describes it in the form of a narrative which depicts for every action the persona(s) and system perform, however it does not state anything on how this is actually done.

In this chapter the two main use cases, going for a walk and interacting with the Dogg0, will be discussed.
