Another view of virtual worlds

  1. 1. A different take on virtual worlds Thomas A. Finholt and Erik Hofer School of Information University of Michigan SCHOOL OF INFORMATION www.si.umich.edu UNIVERSITY OF MICHIGAN
  2. 2. Outline Challenges of virtual organizing – Understand cultural differences Overview of CI usage – Networking – Computing CI-based applications - VISIT – HD Video Conferencing – Immersive visualization – Next-generation evaluation techniques SCHOOL OF INFORMATION www.si.umich.edu UNIVERSITY OF MICHIGAN
  3. 3. Lessons from virtual organizing SCHOOL OF INFORMATION www.si.umich.edu UNIVERSITY OF MICHIGAN
  4. 4. Understand cultural differences SCHOOL OF INFORMATION www.si.umich.edu UNIVERSITY OF MICHIGAN
  5. 5. Domain scientists • Power distance – Hierarchical – Bias toward seniority • Individualist – “individual genius” – Solo PI model • Masculine – Adversarial – Competitive • Uncertainty avoidance – Highly skeptical of new SCHOOL OF INFORMATION www.si.umich.edu technologies UNIVERSITY OF MICHIGAN
  6. 6. CI developers • Power distance – Egalitgarian – Bias toward talent • Individualist – Use the Internet to create worldwide communities – Project model • Masculine – Adversarial – Competitive • Uncertainty avoidance – Extremely open to new SCHOOL OF INFORMATION www.si.umich.edu technologies UNIVERSITY OF MICHIGAN

  15. 15. Tinker SCHOOL OF INFORMATION www.si.umich.edu UNIVERSITY OF MICHIGAN
  16. 16. • Seek small wins and leverage the work of others – Linus Torvalds's style of development— release early and often, delegate everything you can, be open to the point of promiscuity— came as a surprise. No quiet, reverent cathedral-building here— rather, the Linux community seemed to resemble a great babbling bazaar of differing agendas and approaches. (Eric Raymond) • Tinker and experiment – To take advantage of the technology one must engage directly with it, and one must allow traditions of practice to be flexibly influenced by it. (ACLS report) SCHOOL OF INFORMATION www.si.umich.edu UNIVERSITY OF MICHIGAN

  19. 19. Infrastructure for ultra-resolution collaboration SCHOOL OF INFORMATION www.si.umich.edu UNIVERSITY OF MICHIGAN
  20. 20. SI maintains an experimental high performance network, with 10 Gb/s links to SI North and West Hall via r-bin-milr (located at SEB). Michigan Lambda Rail (MiLR) provides high performance connectivity to collaborating sites (Wayne State, UIC, NCSA, U. Washington) and national networks. SCHOOL OF INFORMATION www.si.umich.edu UNIVERSITY OF MICHIGAN
  21. 21. SI is not a major consumer of HPC resources. A 6- node AMD Opteron visualization cluster meets most of VISIT's needs, though a TeraGrid development allocation is under review for a joint project with AOSS. SCHOOL OF INFORMATION www.si.umich.edu UNIVERSITY OF MICHIGAN
  22. 22. Various ultra-resolution applications SCHOOL OF INFORMATION www.si.umich.edu UNIVERSITY OF MICHIGAN
  23. 23. SCHOOL OF INFORMATION www.si.umich.edu UNIVERSITY OF MICHIGAN
  24. 24. SI collaborates in the development and demonstration of high-quality video conferencing technologies. Using the iHD1500 software, we transmit low-latency, studio-quality HD video over advanced networks at 1.5 Gb/s. SCHOOL OF INFORMATION www.si.umich.edu UNIVERSITY OF MICHIGAN
  25. 25. The STIET IGERT program, run in cooperation with Wayne State University, uses an uncompressed iHD1500 link to hold a weekly research seminar between Ann Arbor and Detroit, using MiLR. SCHOOL OF INFORMATION www.si.umich.edu UNIVERSITY OF MICHIGAN
  26. 26. SCHOOL OF INFORMATION www.si.umich.edu UNIVERSITY OF MICHIGAN
  27. 27. SI recently completed the construction of a new 100 megapixel OptIPortal tiled display. This cluster-driven tiled display runs the Rocks Linux distribution and the SAGE graphics middleware from UIC. SCHOOL OF INFORMATION www.si.umich.edu UNIVERSITY OF MICHIGAN
  28. 28. SCHOOL OF INFORMATION www.si.umich.edu UNIVERSITY OF MICHIGAN
  29. 29. SI collaborates extensively with other units on the application of advanced CI technologies. The Department of Atmospheric, Oceanic and Space Sciences collaborated with SI in the development of a 50-megapixel OptIPortal. SCHOOL OF INFORMATION www.si.umich.edu UNIVERSITY OF MICHIGAN
  30. 30. Engagement with other units allows SI to study the use of advanced CI 'in the wild.' An SI PhD student and CoE UROP Undergraduate are working with the AOSS display on study of visualization in the classroom. SCHOOL OF INFORMATION www.si.umich.edu UNIVERSITY OF MICHIGAN
  31. 31. In addition to visualization, SI is developing collaboration technologies that use these OptIPortals as a platform. Component technologies include laptop screen projection and multiple flavors of HD video (uncompressed, DVCProHD, HDV) SCHOOL OF INFORMATION www.si.umich.edu UNIVERSITY OF MICHIGAN
  32. 32. In addition to 'big networking'-based projects, SI is deploying a sensor network testbed to evaluate the use of wireless sensors in studying the use of new technologies. SCHOOL OF INFORMATION www.si.umich.edu UNIVERSITY OF MICHIGAN
  33. 33. These sensors monitor audio level in buildings as a proxy for social activity. Visualizations of sensor data provide 'social weather maps,' tracking pockets of social activity in a space. Over a long time frame, we can measure how new technologies (i.e. public displays) change how physical space is used. SCHOOL OF INFORMATION www.si.umich.edu UNIVERSITY OF MICHIGAN
  34. 34. We are also developing ways to instrument CI systems. We have embedded cameras in the seams of our latest OptIPortal, which we will use to collect usage data about the system. SCHOOL OF INFORMATION www.si.umich.edu UNIVERSITY OF MICHIGAN
  35. 35. We use the data from these cameras to compute eye tracking coordinates, attention levels or other metrics of interest in real time using computer-vision techniques. SCHOOL OF INFORMATION www.si.umich.edu UNIVERSITY OF MICHIGAN
  36. 36. The future: Combining ultra- resolution with virtual worlds Multitouch, integrated instrumentation, social sensing, and OptIPortals – Context-aware ultra-resolution collaboration OptIPortal availability – International network of OptIPortals (~70) – Approximately $900 per megapixel OptIPortals as bridge between real and virtual worlds – Life-sized representation of avatars – Reflection of real world into the virtual space SCHOOL OF INFORMATION www.si.umich.edu UNIVERSITY OF MICHIGAN
