Motivation
• Alzheimer’s disease is the most common type of Dementia;
• One in three seniors dies with Alzheimer’s or another Dementia;
• In 2012, 15.4 million caregivers provided an estimated 17.5 billion hours of unpaid care, valued at more than $216 billion.
Does every patient need caregiver since she is diagnosed with a form of Dementia? How can Software Engineering help?

Scenario 1 (simple)
1. The GPS sensors sends Msg 30 (sensor data input) to the Input Processor, which parses it and extracts the longitude and the latitude;
2. The InputProcessor sends Msg 43 (GPS Reading) to the VAMCIP module;
3. The Hospital Finder modules sends Msg 47 (Coordinates Request) to the VAMCIP;
4. VAMCIP sends the latest coordinates it got from the InputProcessor to the Hospital Finder module

Scenario 2 (complicated)
1. The GUI sends Msg46 (GUI Address Request) to VAMCIP;
2. VAMCIP parses the address and contacts the Google Maps API to find a route from the current location of the patient to the destination as delivered by Msg46
3. In case a route is found, the VAMCIP sends Msg26 (Acknowledgement) to the GUI
4. The GPS sensors sends Msg 30 (sensor data input) to the Input Processor, which parses it and extracts the longitude and the latitude;30 Oct 2014Daniel Petrov

Scenario 2 (cont.)
5. The InputProcessor sends Msg 43 (GPS Reading) to the VAMCIP module;
6. The VAMCIP module checks if the point is on the route as predefined (using the Google Maps API);
7. Steps 4-6 are repeated or more times;
8. If the position is not on the route, VAMCIP sends Msg38 (General Alert) that the patient is lost.
