Four Key Elements of Virtual Reality Experience
• Virtual World
An imaginary space often manifested through a medium.
A description of a collection of objects in a space and the rules
and the relationships governing those objects.
• Immersion
Immersion into an alternative reality or point of view (POV).
Sensation of being in an environment; mental or physical.
Mental immersion is the state of being deeply engaged;
suspension of disbelief; involvement. The goal of most media
creators.
• The mimesis of a novel – a term indicating how real or at least
consistent with itself a story world is. – Mental, third person POV.
• Sense of presence.
Physical immersion is the state for bodily entering into a medium,
synthetic stimulus of the body’s senses via the use of technology;
this does not imply all senses or that the entire body is immersed
or engulfed.
In VR, the effect of entering the world begins with physical.
Sensory Feedback
An essential ingredient of VR
Most case is the visual sense that received feedback
Haptic (touch) experience is possible
Need high speed computer as a mediating device
• Interactivity
Response to user actions
Interactive fiction; Zork from Infocom, Inc.
History of Virtual Reality
• The Ultimate Display – Ivan Sutherland, 1965
Describe a virtual world provided by the computer
• Head Mounted Display (HMD) – Ivan Sutherland 1968
• Users are presented with left and right views of a computer
generated 3D scene. The user’s head movements caused
corresponding spatial changes in the images.
• Evans & Sutherland Corp. manufacture Image Generators
for pilot training starting in 1968

• More flight simulators are available from Thales Training
& Simulation
