Architecture, Engineering, and Construction (AEC) industry
• Visualization & presentation of designs and project management information
• Coordination/communication between stakeholders

Architectural Walkthrough
• Real-time and interactive
• Real scale
• Depth cues
2008 Doug Bowman, Virginia Tech

What can be done more?
• Allow visualization and creation/modification
• VE/CAD integration

Information: information-rich VEs
• Add information about design rationale, construction schedule, materials used.
• Understand complex relationships between various types of information

Virtual-SAP 2.0

Education
• Constructivist theory of learning– ‘Playful’ learning by doing– Build one’s own mental model of the concept
• Possible interactions:– Navigate to view scene from various locations– Explore parameter space– Test “what-if” scenarios
![Page 8: The Future of Immersive Virtual Environments: issues and challenges Dr. Xiangyu Wang Acknowledge to Dr. Doug Bowman’s lecture notes.](https://reader035.fdocuments.us/reader035/viewer/2022081519/56649f125503460f94c2509e/html5/thumbnails/8.jpg)
Portable classroom-based immersive VE for education
2008 Doug Bowman, Virginia Tech
![Page 9: The Future of Immersive Virtual Environments: issues and challenges Dr. Xiangyu Wang Acknowledge to Dr. Doug Bowman’s lecture notes.](https://reader035.fdocuments.us/reader035/viewer/2022081519/56649f125503460f94c2509e/html5/thumbnails/9.jpg)
Future Directions
• All-Modal immersive virtual system– Visual, Auditory, Haptic, Olfactory, Gustatory,
Vestibular, and Kinesthetic.– Direct display to the brain?
![Page 10: The Future of Immersive Virtual Environments: issues and challenges Dr. Xiangyu Wang Acknowledge to Dr. Doug Bowman’s lecture notes.](https://reader035.fdocuments.us/reader035/viewer/2022081519/56649f125503460f94c2509e/html5/thumbnails/10.jpg)
Future Directions: encumbrances removal
• Approaches to input/tracking– Wireless transmission– Vision-based
• Approaches to output/display– Displays in the world– Displays and display generators worn by user– Autostereoscopic displays: no glasses

Autostereoscopic displays
2008 Doug Bowman, Virginia Tech
![Page 12: The Future of Immersive Virtual Environments: issues and challenges Dr. Xiangyu Wang Acknowledge to Dr. Doug Bowman’s lecture notes.](https://reader035.fdocuments.us/reader035/viewer/2022081519/56649f125503460f94c2509e/html5/thumbnails/12.jpg)
Future Directions: Mapping between components
• Huge potential for empirical research
• For example, – what navigation strategies do users adopt in
fully immersive displays?– Which VE displays are the most useful for
decision-making tasks in the construction industry?
![Page 13: The Future of Immersive Virtual Environments: issues and challenges Dr. Xiangyu Wang Acknowledge to Dr. Doug Bowman’s lecture notes.](https://reader035.fdocuments.us/reader035/viewer/2022081519/56649f125503460f94c2509e/html5/thumbnails/13.jpg)
Future Directions: Platform Immigration of 3D UIs
• Different displays, devices, etc. imply different UIs.
• Example: migrate a UI from HMD to CAVE platform
![Page 14: The Future of Immersive Virtual Environments: issues and challenges Dr. Xiangyu Wang Acknowledge to Dr. Doug Bowman’s lecture notes.](https://reader035.fdocuments.us/reader035/viewer/2022081519/56649f125503460f94c2509e/html5/thumbnails/14.jpg)
Future Directions: Effective collaboration
• Issues:– Awareness– Communication– Floor control– Cooperation– Single-user 3D UI v.s. multi-user 3D UI?

• Group presentation: – May 26, 6:00-8:00 in the lab on the fifth floor– each group 20-30 minutes. – Everyone needs to talk– Should use the feedback to refine the final report
• Final report:– Due Midnight 16/06/2008– Please send the final project file to the tutor and me:
[email protected]; [email protected]– should strictly follow the formatting requirements.
• Final exam:– June 2, 6:00-7:00 in the lab on the fifth floor– Multiple choice questions and essay questions– Most questions are from lecture notes and classroom discussion
