  1. GEOservice: Guidance in an enhanced physical space Projet incitatif GET- Institut TELECOM 2007 • Project team: • Annie DANZART (InfRes at TELECOM-ParisTech) • Gérard MOURET (InfRes at TELECOM-ParisTech) • Christine POTIER (InfRes at TELECOM-ParisTech) • Nel SAMAMA (EPH at TELECOM&Management-SudParis) • Trainees: • Magda CHELLY • Brice DONVAL • Yann PROVOST Annie Danzart

  2. Genesis of the project Guidance in buildings Symbolic location A companion web service providing assistance adapted to human perceptions and representations of physical space Annie Danzart

  3. Objectives A web service for assistance in indoor guidance • Direct access to the service from mobile devices • Guidance with user-centered instructions • Context-sensitive service : • quality of localization • user profiles • An ability to deal with incidents : • occurring in the physical space • due to technical problems A web service to provide for experimentation • Localization in a real context • Methods of communicating spatial information • User-friendliness and quality of the interface Annie Danzart

  4. Fields of study • Interaction with mobile devices • Ways of expressing spatial information (+ Tactile mode) •  Methods of indoor localization using a mobile device • Tool to construct zones of presence (using SVG) • Editor of localization scenarios (Interaction + Location) • A Web service adapted to the objectives and context • An online service (Web + Interaction) Annie Danzart

  5. Interaction with mobile devices • Interface : • Small screens are often cluttered - visibility of information • No keyboard + mobility: no input text • Description of the places : • By function (library, restaurant ...) • By their numbers: Bldg. C, C212 • Information associated with the context : • Level of mobility • Mode of localization • Alternatives • Useful information • Incidents Annie Danzart

  6. Interaction with mobile devices Query : The service informs the user Paths adapted to user profile Annie Danzart

  7. Interaction with mobile devices The user informs the service … Vidéo : http://www.tsi.enst.fr/~cfaure/Projets/videos/TRAJETSM.mov Annie Danzart

  8. Communication of spatial information • Visual and text-based modes: • photos on the screen • buttons to confirm • movement • The bracelet: • signals the arrival of new • instructions • supplements and repeats • visual instructions • LEDs light up or pulse Vidéo : http://www.tsi.enst.fr/~cfaure/Projets/videos/BraceletM.mov Annie Danzart

  9. Construction of the covered areas Loading Query XML generation of XML Click Mouse click Php scripts • Vectorial description of the buildings • Blueprintsfrom AutoCad, Illustrator, etc. • Using a DB with GIS extensions (Geographic Information System) • Identifying areas for spatial analysis • Displaying floor plans using SVG (Scalable Vector Graphics) • User interaction with Ajax Software architecture DB - GIS Back-office Front-office : SVG + Ajax Annie Danzart

  12. Simulator of localization Editor: to define realistic situations • Areas of presence containing • one or more locations • Paths partly outside • the coverage zone Behavior of Geoservice in these situations Annie Danzart

  13. A Web service adapted to our objectives and context GO Requête Generate XML path and content of the web page -------------------- Query XML data and display the new context XML Mouse click Mouse click php scripts Software architecture • Servers: database and php scripts for calculating distances in XML format • Client: receives all instructions of the itinerary and stores images • Smooth operation • Quality and speed of sequences Ergonomics (AJAX) DB Query Back-office: php + sql Front-office : html + javascript, browser Annie Danzart

  14. Communication of the project • Project wiki: • http://www.infres.enst.fr/geoservice/ • GEOservice online: • http://www.infres.enst.fr/projets/geos/GEOserviceWeb//index-PDA.html Annie Danzart
