  • Audience questions.Who has been in Second Life?Who has been in an OpenSim grid?Who has set up their own Opensim server?Who has used a virtual world for development?Challenges you may have had?
  • The Digital Convergence Lab (DCL) provides emerging digital technologies for use in teaching, learning, research, and community engagement. The DCL invites the NIU community to explore new ways of communication and sharing of traditional media (print, audio, video) with new media such as digitized text and artifacts, graphics and animation, social networks, virtual environments, mobile devices, video conferencing, serious games, and simulations.
  • Definitions of virtual world.Bell, M.W. (2008) Toward a Definition of Virtual Worlds. Journal of Virtual World Research. Vol. 1. No. 1. Retrieved on October 3, 2009, from http://journals.tdl.org/jvwr/article/viewFile/283/237Damer, B. (2008). A brief history of virtual worlds as a medium for user-created events. Journal of Virtual Worlds Research, 1(1). Retrieved on October 3, 2009,fromhttp://journals.tdl.org/jvwr/article/view/285/239
  • Kaneva - Similar to Second Life in that is a 3D virtual world for social networking. "Kanevamembers create the digital version of themselves -- avatars -- and then meet up in a vibrant, 3D world based on the modern day. Every Kaneva member gets a Kaneva City Loft -- their own 3D space -- that they can decorate and furnish in their unique style" (About Kaneva). There - "A fully interactive, 3D online virtual world where members can customize and create their own 3D character, meet and hang out with friends in real-time using voice and text chat, build their own virtual homes, participate in events ranging from car races to paintball to fashion shows and even create and sell their own virtual items" (About There). Basic membership is free. Metaplace - The site states that it is an "open platform that harnesses the power of the Web to allow anyone to imagine, build and live in their own unique virtual world" (About Metaplace) This virtual world is in 2D, so a slightly different experience than Second Life. For more information read this CNETarticle. realXtend - " offers a free open source virtual world platform with which you can create your own applications using it as a base."
  • Defined as a 3D application serverReverse engineered from LL browser communication: “We didn’t reverse engineer the browser, but the communication that goes between the browser and Second Life” There is no LL code in OpenSimulatorSo what is it? Can be used to create 3d virtual worlds like Second Life. Can use SL browser or others such as Hippo to view. Like ApacheTalk about the fact that OS is open source and what that means….teams of developers, free, buggy, etc…compare to other open source projects such as Linux, BSD (Berkley Source Distribution), business friendly
  • Alpha software 60%, it does break, lack of documentation (os wiki), no tech supportOpenSim.ini - call for better physics enginePicture of my head sticking out of the ground
  • Some has to do with limitations of SL and some reasons are the capabilities of OpenSim
  • What started as a Second Life dissertation project was rescued by OpenSim when the doc student lost assess to the Teen Grid due to pulled funding.

  • 3. Intro to Virtual Worlds
    “A synchronous persistent network of people, represented by avatars, facilitated by networked computers” (Bell, p. 2, 2008).
    “A place described by words or projected through pictures which create a space in the imagination, real enough that you can feel you are inside of it” (Damer, 2008).
