It encompasses all possible combinations of real and virtual elements, from pure reality to augmented reality (AR) and augmented virtuality (AV) to pure virtuality.
This scale helps to classify and understand different forms of augmented reality.
Definition and Origin of the Term
The Reality-Virtuality Continuum was first introduced by Paul Milgram and Fumio Kishino in 1994.
They described it as a scale ranging from pure physical reality to pure virtuality, with all possible intermediate levels.
These intermediate levels consist of different mixtures of real and virtual elements.
The Scale of the Continuum
The continuum can be divided into four main categories:
- Real environment: There are no virtual components, everything is physical and real.
- Augmented reality (AR): AR overlays virtual elements on top of the real world, such as Pokémon GO or head-up displays in cars.
- Augmented Virtuality (AV): Adding real-world elements to the virtual world. An example is a virtual room that displays real-time data from the physical world.
- Virtual Reality (VR): This category includes a completely virtual environment with no physical elements.
Examples of use
The reality-virtuality continuum is used in many fields, from entertainment to education to industry. In medicine, for example, it is used to train surgeons in virtual environments. In architecture and construction, VR and AR help visualize and plan building projects.
Future prospects
As technology advances, the reality-virtuality continuum becomes increasingly relevant. New devices and software developments are constantly expanding the possibilities for combining real and virtual worlds. The future promises exciting developments that will continue to change our understanding and use of these technologies.

Frequently Asked Questions
What is the role of the reality-virtuality continuum in marketing?
In marketing, companies can use the continuum to create immersive customer experiences, such as virtual product presentations, interactive advertising, or virtual showrooms.
What are the challenges in developing applications along the continuum?
One of the most difficult challenges is the seamless integration of real and virtual elements, especially the precise overlay and interaction between virtual objects and the physical environment.
How does the reality-virtuality continuum affect social interaction?
The continuum enables new forms of communication and collaboration, such as virtual meetings, where people meet in fully virtual environments, or AR-supported conferences.
What are the ethical concerns associated with the reality-virtuality continuum?
Ethical concerns include privacy, security in virtual environments, and the potential impact of immersive technologies on the perception of reality.
