5 Electrical and Computer Engineering Project Specifications And Achievements  Server load time: Under 50ms  Brower page rendering time: Under 5s  Location Accuracy: Building user is in  Map update time: 20s or manual user refresh  User timeout on map: 2 hours (security feature)  Windows application can only be used on Windows  Facebook application is supported on all web browsers with Flash and JavaScript enabled

6 Electrical and Computer Engineering Progress Made After CDR  Real data in database  Flash map Advanced privacy settings Display user information Multiple users in a building Enable location update Confirmation window for location update  Layout of Facebook application  Facebook Application was released 4/12/09 Already 70+ users have added it

7 Electrical and Computer Engineering Flash Map Features  Zoom In/Out (up to 12X)  Map panning with click and drag or with arrow keys  “Remove Me” button as security feature  Colored dot for every person logged in on campus (blue for yourself, red for your friends)  Double clicking to update location  Pop-up window comes up with name, picture, and timestamp of user on map next to dot  Embedded in Facebook application through HTML  Flash translates x and y coordinates to a building name corresponding to database entry

8 Electrical and Computer Engineering Flash Interface

9 Electrical and Computer Engineering Windows Application Specifications  PeopleFinder.exe  Minimal user configuration  Runs in background of Windows Asks user for input : Facebook User ID Number Pings default gateway Runs arp.exe and obtains gateway’s MAC address Packages userid and macaddress for server Sends HTTP request to server with macaddress and userid Windows Application

10 Electrical and Computer Engineering Facebook Application  Main interface for PeopleFinder  Clean and easy to use  Facebook users can add application  Communicates with 3 rd Party Server using PHP API  Contains Flash Map  Canvas PHP page includes Flash map and shows debugging data for application

11 Electrical and Computer Engineering MySQL Database  2 Tables to contain user data and location data  MAC addresses of router  Locations of routers  Unique Facebook ID’s of users  Last known MAC address of user  Last login times  Last locations of users

12 Electrical and Computer Engineering HostGator Server  Includes PHP and MySQL server  Stores all user and location data  Pages requested by facebook.com  Communicates with Windows executable to update user locations  Passes HTML and FBML (facebook markup language) to facebook.com
