• Milgram's virtuality continuum (VC)
– AR are technologies allowing users to operate in real world with additional information provided through artificial means
Ontology of ARmrl
Milgram and Kishino (1994)
e.g. Tangible User Interfaces
Adds CGI to the real world
Adds parts of real worldto virtual environment
Refers to completely computer-generated environment
Immersive or semi-immersive

• Mediated reality
– Second axis (Mediality) denotes modification of reality or virtuality
– Diminished reality (DR) is the direct opposite of AR
Ontology of ARmrl
Steve Mann (2002)
Mixed reality
Augmentedreality
Virtualreality
Modulated(modified,
diminished, etc.) reality

• Early Years of VR/AR: The Sword of Damocles“The ultimate display would, of course, be a room within which the
computer can control the existence of matter. A chair displayed in such a room
would be good enough to sit in. Handcuffs displayed in such a room would be confining, and a bullet displayed in such a room would be fatal. With appropriate programming such a display could literally be the Wonderland into which Alice walked.“
Ivan E. Sutherland, The Ultimate Display, 1965
– The first VR head-mounted display (HMD)
