Slideshow Transcript

1. Slide 1: Adding presence-based and location- based capabilities in Twitter Mugdha Jamsandekar Priyanka Prabhu Neha Sugandh
2. Slide 2: What is Twitter …
3. Slide 3: Twitter  Twitter is a free social networking and micro-blogging service that allows users to send \"updates\" (or \"tweets\"; text-based posts, up to 140 characters long) to the Twitter website, via short message service (e.g. on a cell phone), instant messaging, or third-party applications  Updates are displayed on the user's profile page and instantly delivered to other users who have signed up to receive them.  Users can receive updates via the Twitter website, instant messaging, SMS, email or through an application.  For SMS, four gateway numbers are currently available: short codes for the USA, Canada, and India, as well as UK number for international use.
4. Slide 4: Agenda What had we proposed? What have we done so far? What do we intend to complete? Future Scope
5. Slide 5: What had we proposed ?  An extension to Twitter to include groups.  Use location-based concept to notify group members within a certain area.  Use presence-based concept to notify Twitter friends about one's location.  Show location + presence pages containing messages sent by Twitter friends when they were in the vicinity of the location
6. Slide 6:  Selects a group USER Working  Inputs message to be sent Embed user location using GPS CLIENT Integrate location and group id with message APPLICATION Send message to Server using SMS •Retrieves members in the group selected by the user from database SERVER •Retrieves their latest notified status message+ GPS location •Finds members within a particular distance radius •Sends them this message CLIENT •Show GPS location of each Twitter friend APPLICATION in the vicinity specified •Have a page showing the Twitter messages of these friends when they were in the vicinity specified
7. Slide 7: Technologies used  Device Motorola Symbol MC 35 With Express GPS Windows based OS
8. Slide 8: What have we done ? Client-side: User will have a form-like interface to start the application She/he selects a group from her list to send Twitter text message or simply send to 'Everyone‘ Send Message to Virtual User
9. Slide 9: What have we done ? Client-side: Get GPS of user from device and store in a file GPS Information: Latitude, Longitude Message = GroupID + Latitude + Longitude + Message (Using proper conversion) Send message to the server
10. Slide 10: Client Side : Technologies Used Emulator: Pocket PC 2003 Development Framework: .NET Framework 2.0 IDE: Microsoft Visual Studio 2005
11. Slide 11: Server-Side Technologies Users For Location Based part: Google Maps API Web application hosted on our own domain http://twittermaps.s41.eatj.com/map/twittermap1.jsp Apache Tomcat 5.5, MySQL 5.0 Admin, Java 1.5
12. Slide 12: Getting the GPS co-ordinates  GPS - Twenty-four operational satellites in orbit. -Satellites are spaced in orbit so that at any time a minimum of six satellites will be in view  Interpreting Raw GPS data -NMEA standard -Example sentence $GPRMC,040302.663,A,3939.7,N,10506.6,W,0.27,358.86,200804,,*1A “DDD°MM’SS.S”, “DD°MM.M’”, “DD°” for latitudes and longitudes
13. Slide 13: Workflow Compute  t A wants User distances from GPS info in the to send a message to database all friends in a range r Show a page Show on map containing each location of Twitter the retrieved messages for all user co-ordinate the returned users
14. Slide 14: Details  Depending on each user’s privacy setting, his GPS co-ordinates will be stored in the server database.  When a user wants to use the location based feature, all his friends who lie in a specific range will be retrieved along with their GPS co-ordinates and Twitter messages they posted at those locations  Render each retrieved location on maps  Show all the Twitter messages retrieved as above on the Location Based Page
15. Slide 15: Screenshots
16. Slide 16: Screenshots
17. Slide 17: What had we proposed? Server Side:  Would be a virtual twitter user  Users would follow the twitter node and request server to send direct twitter messages  Server would parse the direct messages and send it to people according to the options selected by user.
18. Slide 18: What have we done ? Server-side:  Message sent to the user is split into: group id, latitude, longitude and message  The latitude and longitude information is added to the database  The group members are obtained from database/all friends (from twitter).  The location information is obtained from database for group members/all friends  The proximity is calculated and message is sent to nearby users who satisfy criteria.
19. Slide 19: Server Side Technologies Used For Presence based part MySQL 5.0 for storing the database username groupid membername username groupid latitude longitude message Java 1.5 :Java.sql package JSP
20. Slide 20: Future work….  Using ad sense to exploit the presence + location information  Automatic Recommendations for locations based on friend’s Twitter messages at that place
