1. eContrails An iPhone application for the Air Force Academy Colby Anderson, Louis DeScioli + Dr. Roy Pargas • Abstract • Portable, accessible, easily searchable version of the issued knowledge book for freshmen • Quizzing function built in for quick, on-the-fly studying • Includes a testing function that enables immediate, standardized grading and feedback across the Cadet Wing • Encourages new, more productive forms of testing than the existing manner • Background • At the Academy, freshmen have a knowledge test once a week. The information that they are tested on comes from a small book, “Contrails” that every cadet is issued. Freshmen often face the dilemma of feeling the need to study, but not wanting to bring their “Contrails” with them every where they go. • In the CS495 iOS development class, we were encouraged to develop applications that would directly help the cadet wing. The two of us came up with the idea of making an iPhone-friendly version of “Contrails” that would encourage and enable freshmen to study more often and therefore do better on their knowledge tests • Results • The application has 3 main views: Probook, Contrails, and Testing. Each of them has a persistent search bar at the top to easily sift through the info • The Contrails view contains the basic knowledge information broken up into different sectons and table views • The Probook view contains the various weeks of information. Each week slides into the information that that week contained • The testing view contains the grades of past knowledge tests taken and any current tests that are open for taking. • Discussion- iOSdatabasing and storage • For this project, we used a sqlite3 database on the device to store the actual “Contrails” information, the Core Data structure built into iOS to handle loading the database into the interface, and an external SQL server to push out updates to the probook part of the database CoreData External SQL server (Push updates) • Conclusion • The application will be continued to be developed. Future iterations offer the possibility of linking the testing feature to an outside server to send up grades • Acknowledgments: LPC would like to acknowledge Dr. Roy Pargasand Mr. Del Christman for their help and involvement in our project Sqlite database(“Contrails” information) By: Leaping Pig Creations
