Virtual Environments and Virtual Reality

• Attributes of Virtual Environments:

• Computer-generated representations of real or imaginary environments; Experienced as three-dimensional via a number of senses - visual, aural and/or tactile;
• Objects within these environments are independent of the user and can display real world behavior;
• The user or users have autonomous control - the freedom to navigate and interact with objects, using a number of different viewpoints;
• Interaction occurs in real-time; and the users experience feelings of presence and/or immersion.
