  2. MOTIVATION • Necessity : -- Information Anywhere - depending on user devices -- Information when Useful -- Information according to User Context & Preferences

  3. OUTLINE • Project Goals • Architecture • Design • Technical Issues • Progress So Far • Conclusion & Future Work

  4. PROJECT GOALS A stock Information System • Presents Information at the current user location. • According to current user context • Using the most appropriate Device -Desktop -PDA -Mobile • Within the shortest time possible

  5. ARCHITECTURE Desktop Server UserAgent PDA Cellphone

  6. DESIGN Internet Server Network Utilities UserPreference_Module( ) NetInfo_Module( ) Location_Module( ) MsgCompose_Module( ) Send_Module ( ) Client on User Device

  7. Implementation &Technical Details • User Context & Preferences • Location • Network Utilities like rusers daemon(UNIX),NBTScan(Windows NT,2000) • Explicit user input • Interfaces to other location systems(Future work) • Preferences • Stored preferences. • Agent based learning and decision process(Future Work) • Information Gathering Yahoo Quote Server (http://quote.yahoo.com)

  8. Implementation & Technical Details • Information Delivery Dependson user location and preferences Desktop -- NET send messages PDA and Mobile phones --WMLcards (mobile device checks ,and pulls information periodically ) -- Emulated on ,NOKIA Mobile Internet Toolkit -- Use of Push Access Protocol(Future work)

  9. Conclusion • A prototype for a more generic Information delivery system. -- Applicable to wide range of applications -- Extensible number of information sources

  10. Future Work • Exploring the role learning,decision making Agents can play in applications like these -- proposed agent platforms ,Grasshopper(IKV++),Aglets(IBM) • Interfacing with location Systems • Implementation on real WAP enabled systems
