A form of advanced game style virtual world is a MUVE (Multi-user-virtual environment).
In this simulation promoting scientific inquiry skills, students are able to play the role of scientists taking on authentic tasks, scientific procedures, and self-designed experiments impractical in the real world (e.g., Water Sampling and analysis). (Dede et al., 2004 and Dieterle and Clarke, 2007.)
Low-tech: Basic links to representative collections and information.
High-tech: State of the art virtual museums are employing dynamic interactive virtual reality network services and realistic objects that can be viewed in 3D and manipulated with haptic control cubes (e.g., Huang, 2005).
Virtual Studio teaching environment from Dolgovesov et al. (2003).
Mobile Interactive Learning Objects (MILOs) which are rendered through the Mobile Learning Engine (MLE), a multimedia-based application for cell phones.
Holzinger et al., (2005)
a) Demonstration of different types of mobile devices participating in collaborative remote visualization session.
b) A PDA receiving a reduced pixel image. (From Lamberti and Sanna, 2007).
Teaches students about the interrelationships of soils, landscapes and hydrologic patterns.
The 3D simulations draw on authentic data from soil profiles and are modeled after water tables values of actual well data and can form 4-D (i.e., space-time) visualizations.
Ramasundaram et al., (2005)
An example of computer-generated holography (CGH) from Slinger et al., 2005.
This is accomplished by taking a laser-produced wavefront, forming a computer-calculated holographic fringe pattern, and sending this pattern through a spatial light modulator (SLM) which in turn diffracts the light into an interactive 3D image
Virtual and remote experiments with haptic design permit the online learner to have a tactile experience by adding a simulated response, such as pressure to a hand.
