Virtual Reality can best be defined as: "a realistic and immersive simulation of a three-dimensional environment, created using interactive software and hardware, and experienced or controlled by movement of the body" (Dictionary.com).
It can also be defined as "an immersive, interactive experience generated by a computer" (Pimentel & Teixeira, 1993).
We can create this environment through the use of all sorts of technological devices.
The most important hardware is a screen that projects a virtual image that the viewer is seeing in 3D. From there they respond to what they are seeing through movement. These movements can be done through exercise or they can be done through the use of a control device such as a joystick or remote control.
Children can explore virtual replications of historical settings.
Children can visit locations and people. They can interact and learn first hand what life was like in the past by experiencing their way of life up close and personally.
Example: Taking a virtual tour of Jamestown and being able to see up close what the settlement looked like in the 1600s.
Students can play interactive games that involve math skills in a virtual reality setting.
Counting, sorting, and other mathematical concepts can be worked upon in 3D and through body movements giving students a different experience than the one in their standard classroom.
