7 Electrical and Computer Engineering Progress  Functional implementation of the UI Used familiar Calendar App for user input and Google Maps and a custom overlay for the map output  Collected a test group of alpha users  Routing algorithm functional but a less than optimal runtime. Consider priority queue or point-pairs table for optimization

8 Electrical and Computer Engineering Progress  Original data set is currently in the application. Simple and contains roughly 300 nodes Works for getting between any two points on campus  New data set in the works Will include over 1000 nodes Will allow the app to draw accurate lines along walkways

18 Electrical and Computer Engineering Klaus Kristo  Wrote code to load data from CSV file into Core Data  Interfaced Core Data with shortest path and routing algorithms  Reviewed and fixed data points  Core Data Model Design

19 Electrical and Computer Engineering Clem Leung  User Interface Integrating Multiple Components from Map / Task Edit / Table Views Annotation and route overlays Task / Map Data  GPS Optimized the GPS coordinate input  Performance Testing and Debugging  Core Data Model Design

20 Electrical and Computer Engineering Adam Frieden  Core Data Model Design  Modified routing and scheduling with Core Data model  Interface algorithms with Google API  Data flow between software components  System debugging

21 Electrical and Computer Engineering Chris  Data points  Helped setup Core Data

22 Electrical and Computer Engineering CDR Outline Current Software Design Progress Summary Working Demonstration MDR Review Deployment Plan Team Responsibilities Deliverables for FPR

23 Electrical and Computer Engineering Deliverables for FPR  Google Application synchronization  Polished User Interface  Release and User Feedback  Algorithms running within specifications

24 Electrical and Computer Engineering Specifications  Routing algorithm run time – not met 8-15 seconds for up to tasks  User Interface – not met To be determined by alpha release  Accuracy – not met To be determined by alpha release

25 Electrical and Computer Engineering Budget  $ remaining from MDR  Spent $ for more books Core data reference material User interface design and guidelines More example code with documentation with MapKit, CoreLocation, and Core Data libraries  We have $ left
