This document analyzes the role of Virtual Reality (VR) in e-commerce, exploring what products and services sell well online. Standardized products, such as books, CDs, and software, perform effectively, while less standardized items like clothing and furniture struggle without physical interaction. The potential for VR to enhance online shopping experiences is discussed, including its capability to allow users to view items in 3D and from multiple angles. The document also considers VRML's applications and limitations for creating immersive online experiences.

Virtual Reality for E-C Ralph Westfall March, 2009
What Sells Well on the Web? • books • CDs • software • financial services (stock trading) • travel reservations • computers • other?
What About? • clothing • cars • houses (purchase without visit) • furniture • perishables: fresh fruit, vegetables, fresh meat, etc. • other?
Conclusions • standardized products sell well on web • customers know what they are, what they do • price & service become major issues • less standardized products that vary in quality don't sell as well • people want to see and try them before purchasing
Virtual Reality • can see things in three dimensions with VR • similarities to virtual reality entertainment • don’t need a VR headset, gloves, etc. to use • use VR equipment with computer in future? • could transform HTML into a 3D system • 3D environment for 2-D images, text, scripts, and multimedia, instead of 2-D desktop?
3D Images and Movies • need to use special glasses with one red lens and one cyan lens (blue green) • 3D gif • not impressive without glasses • do it yourself 3D: images • 3D movies • Google's 3D Warehouse
Can Virtual Reality Help E-C? • makes it possible to view an object from all angles • but still can't: • touch, feel, try on • taste • sniff and smell
Potential Web VR Applications • on Internet or organizational intranets • entertainment • shopping • real estate sales • education/training • decision support systems (DSS) • analysis and decision making
3D Product Demonstrations • Dell SAN storage device • Cisco carrier routing system • "Smart" furniture catalog • may need to install to use items • note (View>Source) that many of these demos use Java applets and JavaScript
VRML • virtual reality modeling language • VRML may be pronounced as "vermal" • language for creating 3D images • standardized 3D data interchange format for other 3D applications
VRML Capabilities • translation: change position • scaling: change size • rotation: 3 different ways to turn (X, Y, Z) • lighting/shading • perspective (lines converge in distance) • texturizing surfaces • camera points of view • navigating (older IE versions)
VRML 2.0 Code Example #VRML V2.0 utf8 # cone2.wrl (hotlink to this filename) Shape { geometry Cone { bottomRadius 1.4 height 2.0} appearance Appearance { material Material { diffuseColor 1.0 1.0 0.0}}}
More VRML • code • image • computer integrated manufacturing models (PDF appears to work in both, but .wrl may crash Firefox)
Using VRML on the Web • not built into (even latest) major browsers • have to install VRML plugins for Netscape • a lot of Microsoft VRML references are old • "Retired KB Content" • VRML not supported in Windows 2000 • Cortona 3rd party add-on for IE, Mac
VRML Limitations • very difficult to create content without tools • based on geometric figures • cone, cube, cylinder, sphere • VR window not integrated with browser • but may have HTML support inside • at 1st, navigation doesn't seem easy, natural • poor performance (older machines, slow connections)
VR Demonstrations • Interactive 3D Web Presentations • 3D page of the week • Introducing 3D Examples • Tribute to World Trade Center in 3D • Cubic VR Gallery (Apple QuickTime) • Microsoft video (avi)
Creating VR Applications • different kinds of authoring tools • drawing programs generates VRML • “stitching” photographs together • gaming systems adapted to commercial use • Java 3D can create VR images • Macromedia Flash can also create 3D • free tutorials (below ads)
VR Hardware and Equipment • Virtual Realities, Inc. • Virtual Guidebooks article • Google Directory • 5DT (Fifth Dimension Technologies) • "augmented reality" (AR) • Wikipedia article • Howstuffworks article
3D Free Trials • trueSpace7.6 (bought by Microsoft) • Blender (open source) • Real2Virtual 3 D • includes a Pocket PC image viewer version • Demicron WireFusion • Pharus 3D Builder • 3ds max • Bitmanagement Software (test versions)
VRML Tutorials • Introducing VRML • VRML Primer and Tutorial • Autodesk 3ds Max Crash Course
VRML Conclusions • VRML may not be best VR solution • OK in specialized niches • organizational applications • training/education • CAD languages rather than VRML? • 3ds max is from Autodesk, Inc.
Gaming Systems for VR • Unreal Engine3 • demo (version 2)
Unreal + VRML • create in a 3D authoring tool • e.g. 3ds max • export as VRML data • import into UnrealEd and finish there • UnrealEd comes with Epic games
Exercises • find examples of VR or 3D on web • including 3D gifs • find sources of free VRML objects • download • install VR viewer on a computer and run the code
VR References • these are all quite dated • Sweeney, T. “Unreal Technology FAQ” • University of Michigan Virtual Reality Laboratory (VRL) • medical uses
