Milgram’s reality–virtuality continuum [12]
|
Milgram, Takemura, Utsumi, and Kishino [12] place AR in between reality (real environment) and virtuality (virtual environment) on the reality-virtuality continuum. This is a continuous scale ranging between reality, where everything is physical, and virtual reality, where a complete virtual environment is created by a computer. Mixed reality is located between them, and includes augmented reality (AR) and augmented virtuality (AV) |
