4Electrical and Computer Engineering
Current Software Design
Implementation of Core Data• Allows us to have persistent objects
Completed mapping out campus• Currently improving accuracy by increasing node density
Near-Complete UI• Cosmetics and ease of use may be improved in the future• Google Maps used with custom annotations and an
overlay for drawing lines

7Electrical 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
8Electrical 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

Budget
$400.00 remaining from MDR
Spent $125.00 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 $275.00 left
