Video - What is Augmented Virtuality?

And what is Mixed Reality?

Professor Steve Benford explains the concept of Mixed Reality in this interesting video, with devices like the Oculus Rift and Hololens now pushing Virtual Reality and Augmented Reality into the spotlight. In 1994 Paul Milgram and Fumio Kishino defined a mixed reality as "...anywhere between the extrema of the virtuality continuum," where the virtuality continuum extends from the completely real through to the completely virtual environment, with augmented reality and augmented virtuality ranging between.
