A virtual relaity interface device that programs the computer to change modes in response to gestures made with a glove.  Some use fiber optic cables and some use strain sensors over joints.

A vertual reality interface device that is the simplest of interface devices.  Most have on/off buttons, some have knobs, dials, or joy sticks.  Operate with six degrees of freedom.

A virtual reality interface device which is a helmet with a device on top which signals head movements.  A computer continually updates the simulation to reflect new perspectives.

A virtual reality interface device where sensors read facial expressions/body movements and transfer information to the computer for animation purposes.

Allows a person to interact with another live, real place at a different physical location other than their actual location.  Involves life-size images and in some situations, participants may be able to manipulate devices or the environment in the remote location.

The type of virtual reality that requires additional equipment.  It is the most effective type of Virtual Reality.  Eyes, ears, or other body senses are isolated from real environment and fed inforamtion that is generated by the computer.

A simulated environment that involves computer-generated graphics, is 3-dimensional, is extremely interactive, involves the use of human senses and exists in many different forms.

A virtual reality interface system that uses a viewing box suspended from a rotating arm.  Uses handles on box sides to move image around.  Buttons on handles allow user to interact with the object. (Can also hook up data gloves)

One of the most "immersive" virtual environments, it is a 10x10x9-foot darkened cubicle.  Enables the user to experience the sensation of being "inside" the data.
