  1. CMPUT 301: Lecture 34Networks, Hypertext, Multimedia, and the Web Martin Jagersand Department of Computing Science University of Alberta Based on notes from Pierre Boulanger, Ken Wong, Martin Jagersand

  2. The WEB • Many servers, many content providers • Loosely connected database • Many formats, types of data • Overwhelming?!?

  3. The WEBContent Design • Text: • Linear text • Hypertext, frames, navigability aids • Multimedia: • sound • images • Animation, video • 3D • Interaction, remote control, meetings

  4. Page Design • Cross-platform design: • many platforms • cell phone, handheld, notebook, desktop, high-end workstation, Networked meeting rooms, 3D Viz room • various versions of browsers • collect them all • WYSIWYG • he’s dead, Jim

  5. Text • Issue: • imposes a strict, linear progression on the reader, according to the author’s ideas of what is best

  6. Hypertext and Hypermedia • What: • non-linear structuring of information • traversed in many different ways • chunks of media • e.g., text, graphic, movie, voice, sound, etc. • links between chunks • e.g., technical terms, hotspots

  7. Hypertext and Hypermedia • What are some problems or issues for hypertext or hypermedia systems?

  8. Hypertext and Hypermedia • Some issues: • “lost in space” syndrome • presenting context • determining coverage • printing the content • supporting tours

  9. Current Technologies: web browser web server HTTP HTML CSS CGI Javascript Java plug-ins SGML XML MathML XHTML DOM XSL … World Wide Web

  10. IIRO Project • Interactive Intelligent Remote Operations

  11. Objectives of the IIRO Project • One of the goals of this project is to demonstrate that safe, effective, and reliable monitoring and control of mine operations can be performed over satellite and terrestrial communication links (including the Internet), using models created from various sensors located in a mine.

  12. Athabasca Oil Sand Deposit Surface mineable Athabasca Syncrude Suncor Fort McMurray Peace River Cold Lake Edmonton Lloydminster Calgary Province of Alberta The Oil Sands of Alberta contain 1800 billionbarrels of bitumen. Syncrude leases contain 8 billion barrels of recoverable reserves.

  13. Syncrude North Mine

  14. Excavator RH400 Under Repair

  15. How to Create a Virtual Mine Model Satellite Picture Infrastructures Models Ore Data Virtual Avatar REMCAM Survey Data

  16. Virtual Avatars and Work-site Modeling Virtualized Site Real Site

  17. Virtual Avatar (REMEX) REMCAM Visual Data Display Virtual Control Virtual Data Analysis Agent Virtual Query System GPS Position Virtual Diagnostic Interface

  18. Virtual Avatar (REMEX)

  19. Goal of project ROSA • The goal of project ROSA (Robotic Operation with Supervised Autonomy) is to develop and demonstrate that intelligent systems technologies can provide remote robotic equipment with local intelligence capabilities for ground control of space systems.

  20. NRC Version of Project ROSA(Remote Operation with Supervised Autonomy) VR Operator Interface Environment Modeling Interface REMCAM Semi-autonomous Environment Modeling System Automated Mission Foreman Communication Network Behavioral Virtual Mission Planning Tools Semi-autonomous Remote Robotic Agent Behavioral Mission Executor Physical Modeling Sub-system Virtual Robotic Simulation Sub-system REMSENS

  21. Trajectory control Rendez-vous operations Assembly Guidance control e.g., Laser sensor for SVS STS-88 mission Proximity Operations

  22. Virtual Museum Sound Archive Distributed Virtual Data Server High Speed Network 3D Models Archive Interactive Virtual Stations Text Archive Virtual Models Images Archive

  23. VR Tour: Tomb of Tutankhamum The VR tour shows visitors the Tomb as they would experience it today.

  24. CMC 3-D Virtual Reality Theatre • Features: • Seating for 20-25 visitors • 3 m x 4.6 m (10’x15’) screen • Electrohome projector • SGI Onyx 2 Reality computer • Passive polarizing glasses • “VR Tour Guide” hosts

  25. Digital Repatriation A replica of Tutankhamun’s mask was scanned and the 3-D model inserted into the tomb model.
