Museum Virtual Worlds

Creating objects and experiences that tell the multifaceted story of the number Pi is nothing less than serious fun.  Now in it’s third year being celebrated by the Exploratorium community in Second Life, and in it’s twenty first year being commemorated world-wide, Pi Day is a unique opportunity to be amazed by the relevance of the ever repeating number yielded by dividing the circumference of a circle by its diameter.   Exploratorium staff and SL community members  have created  unique exhibits that let avatars experience, learn about, and contemplate Pi.  Exhibits on display all month with a special event on Pi Day 3/14/2009 from 1:00 - 3:00 PM PDT on Exploratorium Island and at Sploland.

Pi Day 3/14/2009 in Second Life

Douglas Gayeton said to crowds both corporeal and digital that Fabricated Realities,  the mixed-reality screening of his film, Molotov Alva and His Search for the Creator: A Second Life Odyssey, was “surreal.” Not just because the simultaneous screening occurred at the Exploratorium in San Francisco and on Exploratorium Island in SL, but also because SL creator Phillip Rosedale was in the (real) audience.  40 people at the Exploratorium watched the film as well as projected views showing the same number of  avatars, gathered in an amphitheater in SL for the screening and opportunity to dialogue with the filmmaker. The audience in SL enjoyed seeing the live scenes from their world streamed to the theater in real life, then back again into avatar space. After the screeniing, Doug spoke about his own odyssey making the film, collaborating with a SL resident who he’s never met IRL (in real life), and shared his insight about the continually changing virtual world medium.

Our upcoming “mixed reality” video screening event, Fabricated Realities, which will occur on January 24th at our museum in San Francisco and on Exploratorium Island in Second Life, poses some unique technical challenges.  Like other public programs for which we’ve created a virtual counterpart, we’re taking advantage of things we’ve learned before and techniques and processes we’ve developed.  We’ve scaled back part of the initial plan for what videos signals will be digitally encoded for streaming into SL, but will keep those elements in mind for future cinema arts related programs.

In this event, we’ll combine two audiences, one real, one virtual, to hopefully create an integrated experience where a filmmaker can interact with people in front of him and avatars projected alongside.  Both audiences will view the artist’s  documentary shown on a screen in front of them at almost nearly the same time.  Only a slight delay of a few seconds occurs when we encode video and stream it into the virtual world. Wayne Grim, one of my colleague’s at the Exploratorium, created a theater configuration diagram and an audio/video/networking signal-path diagram that shows how we’re setting up those signals in the McBean Theater at the Exploratorium.

I’m using the term “porting” since it speaks to the process of creating versions of a multimedia museum floor exhibit for online web and virtual world.  The Exploratorium has several examples of interactive exhibits that were designed for the real museum which have subsequently been translated into a form that works in our virtually real museum spaces including our website and in Second Life.  One of the latest additions to these virtual spaces is the exhibit, “Divided Attention.”  A perception exhibit that’s part of the Exploratorium’s Mind exhibition, it explores our ability to pay attention to several things at once.  In the exhibit, you follow a number of colored balls that move randomly and slowly change color to the same color as a set of colored balls that the balls are mixed in with. You can vary the number of balls you must keep track of. Exhibit developers designed a version of the exhibit for the exhibition website that I think faithfully reproduces the physical exhibit, sans the shared social interaction affordances of the museum floor.  This version works great as an individual experience and is fun to use.

SL resident and Exploratorium fan Patti Ceawlin, a builder and scripter focusing on physics exhibits, decided to adapt the Divided Attention exhibit for SL.  She got the essence of the exhibit concept and built a dynamic, interactive 3D version which can be seen on Exploratorium Island.  Visitors to the exhibit have commented that it’s a lot harder to keep track of a greater number of balls moving in 3D space as opposed to 2D space like the versions of the exhibit on the website and in the museum.  The SL exhibit allows the avatar to control her/his position in relation to the plane the balls are moving in by moving the avatar or a camera POV.  I’m not sure if or how this affects a visitor’s ability to keep track of the moving balls, but that presents an interesting twist and something we’ll have to observe.

A new event involving virtual worlds currently being planned at the Exploratorium is Fabricated Realities.  This will be a mixed-reality event that takes place at the Exploratorium in San Francisco and on Exploratorium Island in Second Life.  The Exploratorium’s Cinema Arts Program will present a screening of Douglas Gayeton’s machinima documentary, Molotov Alva and His Search for the Creator: A Second Life Odyssey at 2pm PST on January 24, 2009.  Doug, who will be part of the public program at the museum, will also appear in SL via live webcast.  The idea is to bring the film, speaker, and audience together from the two spaces.  We hope the interaction will work and are planning to include a projection screen in the physical theater that will show the audience in the amphitheater in SL.  We’ll encode and stream the movie into SL in real time so that the audience there will see the same thing as the audience at the museum, with just a slight delay.  We’ll plan to allow the SL audience to ask questions of the filmmaker and to have live video of his reponse streamed back into SL.  The technical setup to manage the video streams and two-way communication between the real and the virtual is a little dicey (more on that in a follow-up post), but we’ll be leveraging our experience with routing audio/video signal for presentation and live video encoding/streaming.

The preservation of knowledge about virtual worlds, including content and events, has become an area of investigation of media research and archiving departments at universities.  Library science and museum collections divisions at several schools in the U.S. have been using virtual worlds for some time to facilitate student interaction and for distance learning applications. Museum collections staff at several museums are experimenting with virtual worlds as a means of presentation and interaction with digital versions of artifacts.

At a recent workshop that I participated in at Stanford University given by the Media-X group, entitled “Preserving Knowledge in Virtual Worlds”, I learned that the Stanford Humanties Lab with funding support from the U.S. Library of Congress’ National Digital Information Infrastructure Preservation Program (NDIIPP) has worked with the Internet Archive to create a new Virtual Worlds Video Archive “dedicated to the academic investigation and historical preservation of documentation of virtual worlds.” The project is also supported by groups at the University of Illinois, the University of Maryland, and Rochester Institute of Technology.

This is a great step towards archiving virtual worlds so that the growing practice of using them for both fun and serious work  is preserved for historical record and future study.  While the collection is focused on moving images that capture the use of and important events in virtual worlds, it provides a basis for potential future expansion that might include virtual worlds platform software and related documents and images. Having the collection as a hub within the IA that people can contribute to and share will help broaden the accessibility of these videos for research and study. The collection features some interesting moments in virtual worlds history including OnLive Traveller, STARBRIGHT World, AlphaWorld, Oz, Habitat (!), Maze War, Club Caribe, early SL, and video of the final moments of EA-Land, Check out over twelve years of virtual worlds videos from many different companies and research institutions in this growing collection.
