Virtual Exhibits on Demand - VED
NFR project 2002-2005http://nordbotten.ifi.uib.no/VirtualMuseum/VMwebSite/VEDweb-site.htm
Project leader: Joan C. Nordbotten
Partners: Jan Erik Vold, IT director Bergen Museum
Anne Karin Hufthammer, 1.aman -”-
Participants: 1 – PhD stipendiat – Vibeke Vold Informasjonsvitenskap
6 – master/hovedfag projects started Fall’02 -”-
19 – hovedfag seminar students Spring ’03 -”-
NFR support: per year: travel + ca. 1300 hours (project assistants)

VED Project motivation
The user – Teacher/student/researcher
– Requiring data/information about a specific topic
– “immediately” – or at most 1-2 weeks
The provider – Museums – world wide
– (Virtual) exhibit topics are determined by museum curators.
– Exhibits are hand crafted. Creation time in man-months
Virtual exhibits are:
– Local few collaborations across
museums
– Self-contained lack links to external sites
– Static predefined
On-line databases are for museum colleagues

VED DB access problems
Information retrieval from museum databases is difficult
Problems include:
– Search interface assumes knowledge of collection DB
– Keyword search with list aids – moderate help
– QBIC (query by image content) is difficult to use
– Result presentation
• Without apparent order
• Bound to 1 DB
• Transient
– Little explanatory information

to develop IT methods, and techniques
to support development of
’on-demand’ virtual exhibits - search & save
from multiple DB sources
for educational applications

”A Whale of a Site”
Paper for the Museums and the Web conference - 2003http://nordbotten.ifi.uib.no/VirtualMuseum/Publications/MW2003paperWebVersion.htm
Application for the VED project
Prototype development:Joan C. Nordbotten
Bengt Hjertholm, h-fag student Informasjonsvitenskap
Jan Erik Vold, IT director Bergen Museum
Prototype location: under development !!http://nordbotten.ifi.uib.no/VirtualMuseum/WhaleExhibit/demo.htm
19.2.2003 / jcn Virtual Exhibits on Demand 13
Goals for the virtual exhibit:– Present Bergen Museum’s (physical) whale exhibit 24 specimens
believed to be the largest of its kind in the world
– Support research, educational, and general public interests
Long-term goals:– Give virtual ’access’ to the whole whale collection 94 specimens
– Provide an interface to associated collections
Current focus: – Presentation of very large objects in a Virtual exhibit
– The use of video
VED - Whale Exhibit goals
19.2.2003 / jcn Virtual Exhibits on Demand 14
VED - Whale Exhibit context
Bergen Museum’s whale hall• 300 m2
• 24 whale specimens– 22 whole skeletons
– 2 crania
– 18 (all) N.Atlantic species
– 1.4 – 24m
– 10 skeletons > 5m
+ large and small fish+ coral
+ Development specimens
+ Images
19.2.2003 / jcn Virtual Exhibits on Demand 15
Imaging challenges– Very large & overlapping specimens
– Only 1 view/perspective available no 3D possibilities
– Lighting
– Funding
Video experiments:
For interface:1. http://museum.uib.no/demo/dyremuseet.MOV2. http://museum.uib.no/bmu/hval/qtvr/1.mov
For data presentation– http://nordbotten.ifi.uib.no/VirtualMuseum/WhaleExhibit/filmOKknoel.mov
VED - Whale Exhibit imaging
19.2.2003 / jcn Virtual Exhibits on Demand 16
Characteristics:– Gives ’walk through’ experience
– Easy/intuitive selection of supplemental information
– good proportions
Requirements:– Requires non-overlapping source objects
– Professional development• expensive to produce
• ’rigid’ – difficult to change/modify
– High-end PC with broadband connection required • unavailable to 97% of the world population (Internet survey
Jan.2003)
VED - Whale Exhibit video interface
http://museum.uib.no/demo/dyremuseet.MOV
19.2.2003 / jcn Virtual Exhibits on Demand 17
Problems:– 5 videos required for the 2 rooms– no natural transitions => ’walk-through’ – Distorted proportions– Relatively long load time

19.2.2003 / jcn Virtual Exhibits on Demand 18
Characteristics:– Own production Nikon Coolpix 4500 digital camera
– Quickly done ca. 10 minutes
– Inexpensive
– Poor zoom quality
Plans:– Develop image/video clip for each specimen
– ’Match’ video time to skeleton length
VED - Whale Exhibit Video for data presentation http://nordbotten.ifi.uib.no/VirtualMuseum/WhaleExhibit/filmOKknoel.mov
19.2.2003 / jcn Virtual Exhibits on Demand 19
Characteristics:– Architect drawing as an interface – inexpensive in time requirements– Quadrant layout for specimen data
• Combination of:– Research collection and– Popular information
– Database based
Further development:– Design development– Addition of text query facility– ’real’ DB retrieval– Multi-Database access
