Introduction 3D Web Basics Adaptivity for 3D Web Sites A Generic Software Architecture for
Adaptive 3D Web Site Conclusions and discussion
Motivation Motivation for the group to choose this topic To learn more about the adaptive technologies in a 3D Web
context. Motivation for the author
To form a general architecture for 3D Web sites, after analyzing the differences between web-based hypermedia and 3D web sites adaptive technology.

Related Research Comparing the web-based hypermedia
and 3D Web sites Analyzing the problems when applying
the Web-based hypermedia adaptive technology directly to the 3D context
Main Findings A general software Architecture for
Adaptive 3D Web Sites
Moh Moh Oo
Two types of 3D Websites 3D VE (tourism sites) 3D models of object (e-commerce sites)
Hypermedia as the mainstream 3D enhances hypermedia Adaptivity is important for both 3D
and Hypermedia. Adaptive web technologies cannot
be directly applied into 3D
Applications and motivation Learning and training E-commerce and product visualisation Virtual museums Architecture and virtual cities Virtual communities
3D Web technologies Complex 3D websites for worldwide users Integrating with other contents Through Input/output devices
Real world-alike imaginary world Benefits
Help people in understanding concepts. Enable a safe environment for specific
tasks. Realistic representation of subjects
or phenomena Benefit
Learners are able to analyse the same subject from different points of view
E-commerce websites with an 3D interface Intention
Provide users the 3D virtual environment representing the store.
Advantages Familiar real-world alike shopping experience Supports customer’s natural shopping actions Satisfy social and emotional needs of
customers
Demands for 3D models 2D images fail to maintain required
spatial information Need detailed digital cultural information.
What 3D presents in Virtual Museums Cultural objects their contextual environment
Situated representation of objects Virtual reconstruction of objects and etc. Build environments that never existed physically
What they can provide for users Possibility to explore inside 3D models Socializing (can meet and chat)
Other possible applications of Virtual cities Improved planning, design and
management of real cities for developers. Detailed guide for tourists. Community resources for residents.
Virtual 3D space for users to interact among each other.
Eg. Alphaworld Collaborative engagement from users
Users build and inhabit in virtual community spaces. (artworks, building and full towns)
Social activities such as virtual ceremony (wedding)
VRML (Virtual Reality Modelling Language) Integrated coherent model of content Text files using hierarchical scene graph Message-passing mechanism Script nodes
X3D (eXtensible) Improvement on VRML in three areas.
New nodes and capabilities, Additional encoding formats, Functional areas (Components)
VRML can be translated into X3D.

Mainly 3D models, but also text, images, videos, ...
Structural organisation
Graph of pages 3D space or graph of 3D spaces
Navigation Through hyperlinks By moving in 3D space (e.g., walking, flying) and teleporting; also through hyperlinks
Other common users’ activities
Reading pages, filling forms
3D object manipulation (clicking, moving, ...)
In a Web-based hypermedia way: Downloading all content from server in
one time, so it will be a time-consuming process of UM updating.
Solution: Monitoring closely the user’s behaviour Send relevant time-stamped users’
actions to the server
Adaptive navigation and interaction support
Adaptive presentation of content
Navigation support techniques (Huges et al.)
Direct guidance Hiding Sorting Annotation
Finite State Machines (Celentano and Pittarello)
Monitor user’s behaviour and to exploit the acquired knowledge for anticipating user’s needs in forthcoming interactions.
Techniques for Web-based hypermedia Optional fragments and altering
fragments Techniques for adaptive presentation
of 3D content Fragment-based approach
Implemented by VRML and X3D Domain limitation

A Usage Data Sensing module A Usage Data Recorder module An Adaptivity Engine A 3D Content Creator module
A 3D store Virtual Environment (VE) Usage Data Sensing and Recording User Model 3D Store Adaptivity
Products Shelves Cart Checkout counter
Shopping navigation Traditional way, e.g. shop browsing, ask
sales advisor……. VE way, a walking product!
Seen products Clicked products Cart products Purchased products
Demographic Data User Preferences about the store Usage Data Product Interest Ranking
Mainly concern where and how products are displayed Product visibility Product exposure level Background music Related Product
Conclusions Introduction and 3D Web basics Adaptivity for 3D Web Sites A Generic Software Architecture for
Adaptive 3D Web Sites Discussion
What is the limitations of this architecture?
