A Mixed Reality Continuum

Milgram and Kishino (1994) created the Mixed Reality continuum, which gives users a way to conceptualize the different mixes of realities--in terms of how the virtual and the real combine.

The Real Environment

The real life (RL) environment involves physical spaces, without digital overlays or information.

Augmented Reality (AR)

Augmented reality refers to the overlay of digital information or experiences into a real physical space. In museums, there may be installations that overlay images, information, and audio into the physical situation. Some involve the uses of informational image overlays on a live driving scene, as an enhancement of current global positioning systems (GPS) technologies. Various art installations involve digital augmentations (mixes of projected images, sounds, and mixed-media effects).

Some location-sensitive delivery of digital information may be considered an augmentation on reality. Mobile devices may be used to pick up on location-sensitive information, such as the delivery of historical information about buildings that used to be on certain city blocks. Other types of location-sensitive information involves the delivery of value-added information in museums to add value to the installations.

"Smart" spaces may track users and deliver particular information in certain ways based on preferences. These technologies have been out in the world for many years and are parts of high-end high-tech homes.

Augmented Virtuality (AV)

An augmented virtuality space is one which includes an information feed from the real world, whether it's a live weather report fed into NOAA's site on weather or some sort of sensor-fed information into an immersive virtual space.

Virtual Environment

A fully virtual environment consists of an immersive 3D space like Second Life(R) or some other multiverse.
