Collaborating in virtual environments

Roland Piquepaille's Technology Trends has a recent post on how engineers have been using collaborating tools in virtual reality environments for almost 20 years:

Now, South Korean and Japanese researchers have tried to compare different experiences of users working together using the Virtual Dollhouse application where two people working together have to build a virtual dollhouse using virtual building blocks, a hammer, and nails. Some of them were in 'traditional' collaborative virtual environments (CVEs) using haptic technologies. Others were working over the Internet as well as over a local area network. They've concluded that users could still work together effectively over a network...

...This application has been developed by Qonita Shahab, Yong-Moo Kwon, Heedong Ko and Maria Mayangsari, of the Imaging Media Research Center at the Korea Institute of Science and Technology (KIST), Seoul, Korea. The other authors of the International Society for Optical Engineering (SPIE) are Shoko Yamasaki and Hiroaki Nishino, of the Department of Computer Science and Intelligent Systems at Oita University (Japanese page and English snippets.
