Application Architecture

Application Windows

1. the client layer - consists of the browser interface (View).
2. the JSP middleware - serves as the controller (business logic) (Controller)
3. the data (Model) resides in the MySQL database

Middleware - Controller

• User authentication and conditional forwarding
• Maintaining user information between page refreshes
• Distance Updates and Distance Bound Search and Update Propagation
• Reopening the Window after Closing

Model - DATA LAYER

Model (cont’d)

Per User information

• latitude and longitude information.
• username.
• email.
• boolean variables indicating change in one of the input values on the main application page (fahad.jsp), to update the data in the database.
• abilities hashmap.
• friends online hashmap.
• friends for help hashmap.
• chat window closed counter, integer variable.
• chat window closed three times in succession (indicating that the user has closed chat window), boolean variable

User Study

1. Where do you rate the application w.r.t the concept
2. Where do you rate the application w.r.t the interface
3. Where do you rate the application w.r.t the functionality
4. Rate your experience with the application
5. Would you like to use the application in future

User Study (cont’d)

• ability to delete the abilities/friends.
• ability to import contacts from social apps (like facebook).
• a mobile friendly interface (besides a browser interface).
• support for non-exact match for the abilities and the one requested by a user.
• support for pictures of the users.
• visual/sound indication for a user logging

Conclusion

• Great potential exists for location aware social networking
• Get help in real-time from near-by users for small physical tasks – novel idea
• Extend the social circle to include friend-of- friends – yet to be exploited
• Opens door to several possibilities – recommendation of places, context based tagging, collaborative content…..
