1. Otto Borchert North Dakota State University Recent Advances in Immersive Virtual Worlds for Education

2. NDSU WWWIC World Wide Web Instructional Committee WWWIC’s Virtual Worlds research supported by NSF grants DUE 97-52548 and EAR-9809761.  WWWIC is an ad hoc group of North Dakota State University faculty dedicated to developing internet-based educational software. The mission goals of WWWIC are to teach science structure and process: the Scientific Method, scientific problem solving, deduction, hypothesis formation and testing, and experimental design.

20. The Virtual Cell

21. The Cell: Rendered in VRML (Virtual Reality Modeling Language)

22. The Cell Users can “fly around” inside the cell.

23. The Cell: Users are assigned goals which range from identify the nucleus early to synthesize ATP later.

24. The Cell Users set up experiments (For example, use a chlorophyll test to check for cloroplasts

25. Experimentation – Users bring samples back to the lab

26. The Virtual Cell User Interface

27. The Cell: Recent Advances With the decline of CosmoPlayer, changing to Java3D With the decline of CosmoPlayer, changing to Java3D Addition of automated registration so a class can sign up for the cell within minutes Addition of automated registration so a class can sign up for the cell within minutes Creation and finetuning of modules (Making the cell look perfect) Creation and finetuning of modules (Making the cell look perfect)

28. " DANA is intended to be a cross-platform information retrieval system for web-based multimedia utilized in anthropological research. " Ultimately, the goal of the DANA project is to create a network of distributed, federated databases containing research quality digitized 3D models, photographs, and video of archaeological and cultural data. " To the user seeking to access a broad variety of data, the client application will seem as though it is a user-friendly interface to a single online database. In actually, the user will be conducting searchers across a wide variety of databases located across the globe. Digital Archive Network for Anthropology (DANA) DANA is a recent advance!

29. DANA Fact Sheet " Though further research is required to implement the distributed, federated network aspects of DANA, the database browsing application currently supports servlet search capabilities for Postgress, mySQL, and Oracle databases. " DANA currently only displays VRML 97 and HotMedia 3D models, though the addition of 3D file formats supported by the NCSA Java3D Portfolio is expected soon. Technology Used: " Java3D " Java JDK 1.3 " Java Web Start " Java Servlets " JDBC " NCSA Java3D Portfolio " IBM’s HotMedia Classes

30. Starting The DANA Applet After installing Java Web Start and the Java3D API, return to the application launch page at: http://atl.ndsu.edu/archive/dana.htm Once there, click the “Launch DANA Applet” button. Next a “login” box will appear, where the user enters in his/her username & password and then clicks the “Login” button to start the DANA applet.
