Museum Association Conference – Brighton – 6-7th 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?o To allow museums to have an online (3D) presence
o To enable interaction with digital representations of collections
• How? By building a set of tools and processes from digitisation to visualisation:o Digital capture of artefacts, 3D modelling and refinement, Database and
content management, Visualisation in virtual or augmented reality environments
o Interoperability i.e. an Open Architecture XML Data Exchange between tools and other systems Internet, Web, graphics and metadata standards

Museum Association Conference – Brighton – 6-7th October 2003
Create: Digitise Artefacts with the Object Modeller
• Method of modelling depends on features of the objects
o Objects with simple geometry are modelled with modified 3ds max or Maya
• For complex models we use a custom built stereo digital camera system:
o Object geometry and textures are extracted from sequences of stereo pictures and merged to produce a 3D textured model
o Portable in order to gain access to fragile artefacts
o Ease of use for museum staff who are not experts in 3D measurement
o Result should be an accurate 3D model of the artefact in terms of shape, texture and resolution
o Automated stereo reconstruction as far as possible
![Page 11: Museum Association Conference – Brighton – 6-7 th October 2003 Building Virtual Museum Exhibitions](https://reader036.vdocuments.net/reader036/viewer/2022062511/551607f1550346a2308b4f39/html5/thumbnails/11.jpg)
Museum Association Conference – Brighton – 6-7th 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 connectivityo search and browse objects
o import and export models
(including models generated by
other methods,
e.g. Mechanical scanning,
Laser scanning)
Manipulate: 3D Modelling and Refinement

Museum Association Conference – Brighton – 6-7th 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
![Page 13: Museum Association Conference – Brighton – 6-7 th October 2003 Building Virtual Museum Exhibitions](https://reader036.vdocuments.net/reader036/viewer/2022062511/551607f1550346a2308b4f39/html5/thumbnails/13.jpg)
Museum Association Conference – Brighton – 6-7th 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.
o Cultural objects
o X-VRML templates
o Virtual exhibitions

Benefits for Small Museums
Sussex Archaeology SocietySix regional museums in Sussex
with some 500,000 objects
John Manley (Sussex Past)

Museum Association Conference – Brighton – 6-7th October 2003
Small Museum Attributes
• Some attributes of small museums…
o They are in the majority
o Often no dedicated ICT staff
o Very often no professional photographic skills
o They are not well-funded
o But they are cherished, rooted in their localities, and aspire to do their best
o They strive to achieve national standards
![Page 20: Museum Association Conference – Brighton – 6-7 th October 2003 Building Virtual Museum Exhibitions](https://reader036.vdocuments.net/reader036/viewer/2022062511/551607f1550346a2308b4f39/html5/thumbnails/20.jpg)
Museum Association Conference – Brighton – 6-7th October 2003
Incarcerating Objects
• The small museum as a prison …
o Objects 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
o We remove them from those local contexts and then lock them in glass
display cases
o We can no longer explore their physicality in the round
o And then the museum curator tells us what’s important about the object
![Page 21: Museum Association Conference – Brighton – 6-7 th October 2003 Building Virtual Museum Exhibitions](https://reader036.vdocuments.net/reader036/viewer/2022062511/551607f1550346a2308b4f39/html5/thumbnails/21.jpg)
Museum Association Conference – Brighton – 6-7th October 2003
Liberating Objects
• ARCO system as liberator …
o ARCO can display, remotely or in-gallery, objects in the round
o Can link objects with other objects and local places where they were
found
o Offers different visual perspectives of an object which can provoke novel
opinions from the viewer, avoiding reliance on the curator
o Enhances the sensual experience of the physicality of real objects
![Page 22: Museum Association Conference – Brighton – 6-7 th October 2003 Building Virtual Museum Exhibitions](https://reader036.vdocuments.net/reader036/viewer/2022062511/551607f1550346a2308b4f39/html5/thumbnails/22.jpg)
Museum Association Conference – Brighton – 6-7th October 2003
ARCO Benefits for Small Museums
• ARCO and small museums…
o ARCO provides interactivity, and intelligent, non-passive artefacts
o Liberates them from the glass case and curators’ labels
o Decreases the psychological distance between object and viewer
o Moves a step closer to allowing objects to be experienced as real things,
once used by local people in their own localities

Conclusions
ARCO is developing an open architecture that integratesstate-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
