6 Museum Association Conference – Brighton – 6-7 th October 2003 ARCO Status Progress so far: o4 prototype systems and components completed, various configurations demonstrated at: COMDEX Fall 2002, Las Vegas EVA 2003 Florence and London Example 4 th prototype components are exhibiting on stand 70 Two Museum User Trials, third in October at Sussex Past oLarge dissemination activity: Vision, Video and Graphics, UK Visualisation, Imaging and Image Processing, Spain Dublin Core, USA Immediate Future Developments: oFinal 12 months of project for more detailed system integration, assessment and evaluation, dissemination activities oTechnology Implementation Plan

7 Museum Association Conference – Brighton – 6-7 th October 2003 ARCO Technology Overview ARCO Project goals Prototype systems and components Digitisation of artefacts 3D modelling and refinement Storing and managing digitised objects ARCO data model Metadata in ARCO Visualisation of digitised artefacts Manjula Patel (UKOLN, University of Bath)

8 Museum Association Conference – Brighton – 6-7 th October 2003 Goals of the ARCO Project Develop innovative technology and expertise to help museums Create, Manipulate, Manage and Present cultural objects in virtual exhibitions both within museums and over the Web Why? oTo allow museums to have an online (3D) presence oTo enable interaction with digital representations of collections How? By building a set of tools and processes from digitisation to visualisation: oDigital capture of artefacts, 3D modelling and refinement, Database and content management, Visualisation in virtual or augmented reality environments oInteroperability i.e. an Open Architecture XML Data Exchange between tools and other systems Internet, Web, graphics and metadata standards

9 Museum Association Conference – Brighton – 6-7 th October 2003 ARCO Prototype Systems and Components

10 Museum Association Conference – Brighton – 6-7 th October 2003 Create: Digitise Artefacts with the Object Modeller Method of modelling depends on features of the objects oObjects with simple geometry are modelled with modified 3ds max or Maya For complex models we use a custom built stereo digital camera system: oObject geometry and textures are extracted from sequences of stereo pictures and merged to produce a 3D textured model oPortable in order to gain access to fragile artefacts oEase of use for museum staff who are not experts in 3D measurement oResult should be an accurate 3D model of the artefact in terms of shape, texture and resolution oAutomated stereo reconstruction as far as possible

11 Museum Association Conference – Brighton – 6-7 th October 2003 A tool for interactive model refinement and rendering Creation of simple models and refinement of digitised models o smoothing the object geometry o reducing polygon count for Internet based rendering o re-applying lighting o repairing missing parts Database connectivity osearch and browse objects oimport and export models (including models generated by other methods, e.g. Mechanical scanning, Laser scanning) Manipulate: 3D Modelling and Refinement

12 Museum Association Conference – Brighton – 6-7 th October 2003 Media Objects from Creation & Manipulation Stages Sample media objects representing cultural objects in the database: Images from the photogrammetry process VRML models exported from model refinement

13 Museum Association Conference – Brighton – 6-7 th October 2003 Manage: Content Management Application All ARCO data is stored in a database for consistency Museums do not manage the database directly, but through a Content Management Application (ACMA) ACMA provides several managers for ease of data manipulation, e.g. oCultural objects oX-VRML templates oVirtual exhibitions

14 Museum Association Conference – Brighton – 6-7 th October 2003 ARCO Data Model Media Object +is included +includes Cultural Object Acquired Object > +belongs to +contains Refined Object > +belongs to +contains > Cultural Object : descriptive curatorial metadata, surrogate for the physical artefact Acquired Object : digital representation of the physical artefact Refined Object : acquired (or refined) object which has been modified Media Object : individual object which makes up a digital representation (3D model, texture maps, description etc.)

15 Museum Association Conference – Brighton – 6-7 th October 2003 Interoperability: Metadata for Digital Artefacts AMS –ARCO Metadata Schema, is a vocabulary for describing processes from digitisation to visualisation: oResource discovery metadata (DCMES) oDescriptive curatorial metadata (mda SPECTRUM) oTechnical metadata (preservation) oThemed metadata (intelligence, effort report) oARCO specific elements Interoperability oData exchange between ARCO components oCross domain and compatibility with museum best practice Implemented with XML Schemas AMS Metadata Editor

16 Museum Association Conference – Brighton – 6-7 th October 2003 Presentation: Augmented Reality Interfaces Visualisation of ARCO media objects from the database oVRML models, metadata, images, virtual exhibitions Three visualisation interfaces, same database contents oRemote Web Interface (search, browse) oLocal Museum touch-screen (search, browse) oLocal Augmented Reality environment (interact)

17 Museum Association Conference – Brighton – 6-7 th October 2003 Virtual Museum Exhibitions and Galleries

18 Museum Association Conference – Brighton – 6-7 th October 2003 Benefits for Small Museums Sussex Archaeology Society Six regional museums in Sussex with some 500,000 objects John Manley (Sussex Past)

19 Museum Association Conference – Brighton – 6-7 th October 2003 Small Museum Attributes Some attributes of small museums… oThey are in the majority oOften no dedicated ICT staff oVery often no professional photographic skills oThey are not well-funded oBut they are cherished, rooted in their localities, and aspire to do their best oThey strive to achieve national standards

20 Museum Association Conference – Brighton – 6-7 th October 2003 Incarcerating Objects The small museum as a prison … oObjects in them once had real lives and, for example, were meant to be handled, or worn, or drunk from, or contained something, or displayed on walls etc, often in the immediate locality oWe remove them from those local contexts and then lock them in glass display cases oWe can no longer explore their physicality in the round oAnd then the museum curator tells us whats important about the object

21 Museum Association Conference – Brighton – 6-7 th October 2003 Liberating Objects ARCO system as liberator … oARCO can display, remotely or in-gallery, objects in the round oCan link objects with other objects and local places where they were found oOffers different visual perspectives of an object which can provoke novel opinions from the viewer, avoiding reliance on the curator oEnhances the sensual experience of the physicality of real objects

22 Museum Association Conference – Brighton – 6-7 th October 2003 ARCO Benefits for Small Museums ARCO and small museums… oARCO provides interactivity, and intelligent, non-passive artefacts oLiberates them from the glass case and curators labels oDecreases the psychological distance between object and viewer oMoves a step closer to allowing objects to be experienced as real things, once used by local people in their own localities

23 Museum Association Conference – Brighton – 6-7 th October 2003 James Stevenson (VAM) Victoria and Albert Museum A large national museum with some 4 million objects Benefits for Large Museums

24 Museum Association Conference – Brighton – 6-7 th October 2003 Object base

25 Museum Association Conference – Brighton – 6-7 th October 2003 Why we make images Publications Catalogues Collections management Web site Education –In the museum –On the web

26 Museum Association Conference – Brighton – 6-7 th October 2003 Education DCMS targets and objectives All funding bodies have similar targets Improve access Social inclusion

27 Museum Association Conference – Brighton – 6-7 th October 2003 How do you describe an object? Words, text Objects are 3D They have a front and back Top and bottom They have mass and volume

28 Museum Association Conference – Brighton – 6-7 th October 2003 Photographer: Pip Barnard

29 Museum Association Conference – Brighton – 6-7 th October 2003 Photographer: Pip Barnard

30 Museum Association Conference – Brighton – 6-7 th October 2003 Photographer: Pip Barnard

31 Museum Association Conference – Brighton – 6-7 th October 2003 How we are doing this? Quick time movies Large volume of content on the web site Panoramas of galleries Virtual spaces

32 Museum Association Conference – Brighton – 6-7 th October 2003 What 3D models can do Add new ways of seeing Give a greater degree of spatial awareness Allow comparison of volume and mass Be placed in virtual spaces Help create the virtual museum

33 Museum Association Conference – Brighton – 6-7 th October 2003 Issues Difficult to achieve Expensive Complex New set of skills Studio or workshop restricted

34 Museum Association Conference – Brighton – 6-7 th October 2003 Tools Easy to use Very simple software Content management Link to museums collections management Simple model refinement Simple insertion into web pages and virtual galleries

35 Museum Association Conference – Brighton – 6-7 th October 2003 Museum User Roles Create test situations Access to museum content Test developments by technical partners Evaluate results Encourage use by other museums

36 Museum Association Conference – Brighton – 6-7 th October 2003

37 Conclusions ARCO is developing an open architecture that integrates state-of-the-art with ARCO specific technologies to enable museums to build virtual exhibitions –Digitisation and modelling of 3D museum artefacts (OM) –Refinement and creation of the 3D virtual museum artefacts (MR) –Object relational database and content management (ACMA) –Visualisation of museum exhibits in virtual environments (ARIF) –Integrated through XML technologies (X-VRML, AMS, XDE) ARCO tools are end user driven through museum pilot sites being closely integrated into the design process Visit us at the ARCO website: –http://www.arco-web.org/ –Stand 70
