Essential Uses Cases:
Launching EMACS
Derived from the Activity Scenarios, this Essential Use Case
illustrates the simplicity of the interaction between the system and the user.
Once again, the goal is to keep the system as simple as possible by intentionally
minimizing the amount of interaction between a climber in an extreme environment
at the limit of his thinking capabilities and a vital signs monitoring system.
