    • Adding presence-based and location-based capabilities in Twitter Mugdha Jamsandekar Priyanka Prabhu Neha Sugandh
    • What is Twitter …
    • 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.
    • Agenda
      • What had we proposed?
      • What have we done so far?
      • What do we intend to complete?
      • Future Scope
    • 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
        • Selects a group
        • Inputs message to be sent
      • Embed user location using GPS
      • Integrate location and group id with message
      • Send message to Server using SMS
      • Retrieves members in the group
      • selected by the user from database
      • Retrieves their latest notified status message+ GPS location
      • Finds members within a particular distance radius
      • Sends them this message
      • Show GPS location of each Twitter friend
      • in the vicinity specified
      • Have a page showing the Twitter messages of these friends
      • when they were in the vicinity specified
    • Technologies used
      • Device
      • Motorola Symbol MC 35
      • With Express GPS
      • Windows based OS
    • 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
    • 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
        • Emulator:
        • Pocket PC 2003
        • Development Framework:
        • .NET Framework 2.0
        • IDE:
        • Microsoft Visual Studio 2005
      Client Side : Technologies Used
    • 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
    • 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
    • Workflow
      • t
      User A wants to send a message to all friends in a range r Compute distances from GPS info in the database Show on map each location of the retrieved user co-ordinate Show a page containing Twitter messages for all the returned users
    • 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
    • Screenshots
    • Screenshots
    • 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 .
    • 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 .
    • Server Side Technologies Used
      • For Presence based part
      • MySQL 5.0 for storing the database
      • Java 1.5 :Java.sql package
      • JSP
      username groupid membername username groupid latitude longitude message
    • Future work….
      • Using ad sense to exploit the presence + location information
      • Automatic Recommendations for locations based on friend’s Twitter
      • messages at that place
    • Thank You
