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].
