2. Guidance in buildingsSymbolic location A companion web service providing assistance adapted to human perceptions and representations of physical space Genesis of the project 12-05-20092Annie Danzart

3. 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 Objectives 12-05-20093Annie Danzart

4.  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) Fields of study 12-05-20094Annie Danzart

5. 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 Interaction with mobile devices 12-05-20095Annie Danzart

6. The service informs the user Query : Paths adapted to user profile Interaction with mobile devices 12-05-20096Annie Danzart

8. The bracelet: signals the arrival of new instructions supplements and repeats visual instructions LEDs light up or pulse Communication of spatial information Visual and text-based modes: photos on the screen buttons to confirm movement Vidéo : http://www.tsi.enst.fr/~cfaure/Projets/videos/BraceletM.movhttp://www.tsi.enst.fr/~cfaure/Projets/videos/BraceletM.mov 12-05-20098Annie Danzart

9. DB - GIS Back-office Construction of the covered areas 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 Php scripts generation of XML Loading Query Mouse click Front-office : SVG + Ajax Click XML 12-05-20099Annie Danzart

13. DB Back-office: php + sql A Web service adapted to our objectives and context 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 GO Requête Mouse click Front-office : html + javascript, browser XML Software architecture Ergonomics (AJAX) Mouse click php scripts Generate XML path and content of the web page -- ------------------ Query XML data and display the new context Query 12-05-200913Annie Danzart
