  2. VIRTUAL WORLD 3D - RESEARCH ACTIVITY VW-3D is a platform to provide e-learning serviceslike web based information and communication for cooperative works in complete virtual worlds. Goals: to experiment VW3D platform and its virtual scenario;to study both the socio-cognitive visual interface and the corrispondence with real scenario. During the design phase, before the VW-3D platform implemetation, studies (Technology, Functionality, Standards and Infrastructure) have been done.

  19. VW-3DThe e-Learning Application Scenario The aimof the VW-3D Project is to reach a conceptual validation of methodologies, platforms and technologies supporting the integration, validation and programming, over a distributed environment, to create correct and coerent 3D spaces and objects where users can learn the contents of heterogeneous and distributed virtual courses (VC).

  20. VIRTUAL WORLD 3D - USER IDENTIFICATION & CLASSIFICATION • User classes • Generic user (randomly access to the system); • Professional user (frequently access to course, information and services. Generally students/teachers and tutors);

  21. VIRTUAL WORLD 3D - USER CLASSIFICATION CRITERIA • Frequency of use • Computer familiarity • Computer software expertise • User mental abilities • User physical abilities and skill

  22. VIRTUAL WORLD 3D - USER REQUIREMENTS • User requirements • General requirements (access to the system through the Web, use of the Net to study, easy to use, efficency, effectiveness , robustness, modularity, portability, etc.); • Functional requirements (use of mouse, access to enquiry functions, real-time and asinchronous communications, etc.); • Technical requirements (active environment, networks, multi-language, integration with distributed multimedia database).

  23. VIRTUAL WOLRLD 3D - RESEARCH ACTIVITY VW-3D Platform VW-3D PlatformStructure Web Site & Java Applet DBMS AVI Multimedia 3D Worlds 3D Objects Virtual Component & SIM

  24. VIRTUAL WORLD 3D - WEB SITE • The Project; • The VW-3D Applet; • Download; • General Informations; • Links;

  25. VIRTUAL WORLD 3D The VW 3D Methodologies has defined the virtual space (External / Internal), the objects, the multimedia and users. The main internal space (ROOMS) are: • The Classrooms; • The Hall; • The Meeting-Points; • The Library; • The Rooms;

  26. VIRTUAL WORLD 3D – THE MODULES The VW-3D is implemented on more than one simple layer. The system is based on a high level 3D representation engine, a Client-Server structure for the communication of distributed messages and a low level layer than starts a precise procedure to retrieve information from the database after that an interactive 3D object has been selected.

  27. VIRTUAL WORLD 3D – THE OBJECTS • The Virtual World 3D has defined the objects and their functionality in the 3D scene to stimulate the end-user interaction with this environment. • The objects are simple metaphores to retrieve contents and documents from the databases. Each room and 3D space has standard objects configuration that characterize the scene. • The objects implemented in the Virtual world 3D are: • Wide Screen for video and slides; • Whiteboards; • Calendars; • Books; • Personal Computers; • Other.

  28. FADVIGEN DATABASE VIRTUAL WORLD 3D – THE BOOKS The books are the most common objects in the Virtual World 3D scenes. They are available in the classrooms, in the hall and in the private rooms (docent and student). This object retrieves documents available for the user in the contextual space wherehe is interacting. Vw-3d/Matrix layer The object “book” makes a query to the FADIVGEN with the informations of the room where it is placed and of the user that is interacting with it.

  29. Si.A. Authoring tool VIRTUAL WORLD 3D – THE BOOKS The book represents also the documents that the end-user saves inside his own repository. The end-user, in the 3D scene, is capable to compose a new document with the Si.A. tool or save paper passed by another user. By this, the end-user will have a new BOOK represented in his library or on his desk.

  30. FADVIGEN DATABASE VIRTUAL WORLD 3D – THE WIDESCREENS In the classrooms, in the private rooms and in the meeting-point are available widescreens where the end-user can visualize didactic contents like video and slides. The widescreens visualize the content retreived by the end-user querying the calendar outside a classroom or clicking the query panel. Vw-3D/Matrix layer

  31. VIRTUAL WORLD 3D – THE WHITEBOARDS The WhiteBoard module is a experimental prototype of shared blackboard that allows to design and to write images. Already experimented in MES project, the WhiteBoard has been integrated in the 3D scene. The WhiteBoard shares the drawings of users that are present in the same room, like the classrooms.

  32. VIRTUAL WORLD 3D – THE CALENDAR The calendar is another interactive 3D object inserted in the 3D scenes of Virtual World 3D. The calendarin the scene informs the end-users which and when a lesson will be available or take place in the real world. The important operation of the object is that each calendar gives a unique info about the lesson. The calendar gives to the user only the info of the lessons available at the classroom or meeting-point that it is associated.

  33. VIRTUAL WORLD 3D THE HALL AND THE MEETING-POINT The Virtual World 3D spaces dedicated to meet other users and to reach general multimedia contents are the hall and the meeting-point. Infact in the hall we have info-point and many wide-screens where the user can connect to internet or listen to general information. The meeting-point is a dedicated space of the hall where the user can stop and interact with other user or make researches on multimedia contents and documents

  34. VIRTUAL WORLD 3D THE STUDENT AND TEACHER ROOM The Virtual World 3D teacher and student rooms are private spaces for the end users as students and teachers. Here the users can display the lessons available in MATRIX platform, save and create their own documents. The objects implemented in all the 3D scene are inserted also in these spaces but each output is differentiated by the context of the space where the user interact with them

  35. VIRTUAL WORLD 3D – THE CLASSROOM The Virtual World 3D classrooms are the spaces dedicated for the online lessons. Here the users can follow and interact with the lesson in real-time, and be present in the classroom with their avatars. To complete the lesson experience the user have many functionalities available: documents repository, video screens , whiteboards.

Virtual World 3D Future Functionality To implement a distributed platform based on server cluster technology that ensures both a more reliability of the functional modules and a fast service; To design advanced collaborative instruments (designer tools, remote controll classroom system, multimedia repository manager system, etc.) To implement a new Multimedia Library, integrated with an advanced search engine, where the end-user can navigate in a 3D scene of the results. To design specific modules to manage room and objects with indipendent management.
