Part 1 - UML Activity Diagram (50 Points) > not one single possible solution, as long as solution makes sense Background you will get a good mark Overview of the System You are working on an innovative application in a start-up company that is developing a Mental Stress Monitoring (MSM) system that helps users manage their daily mental stress. The MSM system is composed of a mobile phone application and a Wearable Physiological Sensor (WPS) (See Figure 1). The WPS assesses the mental stress level of the user by monitoring her or his autonomous nervous system activity as inferred by various biological signals such as heart rate variability, breathing rate, and skin conductance. The phone application controls the monitoring process. It requests a mental stress assessment from the WPS and decides whether the user should engage in a guided meditation session to attempt to reduce her or his mental stress level. The mobile phone! application disregards any mental stress measurements if it deems that the user was engaging in physical activity as excessive movements impedes the WPS from making a correct assessment about mental stress due to signal noise. The system assesses the physical activity level through the mobile phone's accelerometer.
