Transitional
Interfaces
Milgram points out that computer interfaces can be placed on a continuum
according to how much of the user's world is generated by the computer
[Milgram 94] (figure 4). Moving from left to right the amount of virtual
imagery increases and the connection with reality weakens. AR technology
can be used to transition users smoothly along this continuum, as
shown by the MagicBook work [Billinghurst 2001].
