l MultiUser l Exploration l Spatially-oriented virtual worlds l Practical planning and decision making Educational Role-playing Games “Learning-by-doing” Experiences

Virtual Worlds Can: l Collapse virtual time and distance l Allow physical or practical impossibilities l Allow participation from anywhere l Let you interact with other users, virtual artifacts, and software agents l Afford multi-user collaborations and competitive play

The Projects l The Virtual Cell l The Geology Explorer l Dollar Bay l Like-a-Fish hook Village l Digital Archive for Archaeology l Others

The Virtual Cell Rendered in VRML (Virtual Reality Modeling Language)

Users can “fly around” inside the cell

Users are assigned specific goals For example: Identify 5 different organelles

Similar to Earth, but opposite the Sun Students “land” on Oit to undertake exploration Authentic Geoscience goals - e.g., to locate, identify, and report valuable minerals Planet Oit

~50 places: desert, cutbank, cave, etc. ~100 different rocks and minerals ~15 field instruments: rock pick, acid bottle, magnet, etc. ~Software Tutors: agents for equipment, exploration, and deduction Planet Oit The simulation
