Methodology

Key Technologies

Key technologies were also selected for each use case. A pre-defined list was created from which to select relevant
technologies (see table below). This list is not intended to be exhaustive; it was selected by the expert group based on the
technologies most pertinent across the Citiverse use cases. This list may evolve based on the work of the Emerging

Technology Track and can be integrated into future iterations of the Citiverse Use Case Taxonomy.

Technology Definition Reference
Metaverse An integrative ecosystem of virtual worlds offering immersive experiences to users, that modify pre-

existing and create new value from economic, environmental, social and cultural perspectives. FGMV-20
NOTE – A metaverse can be virtual, augmented, representative of, or associated with the physical
world.

Digital Twin A digital twin network is a digital representation of an object of interest. ITU-T
Y.4600

Augmented An environment containing both real and virtual sensory components. The augmented reality ITU-T
Reality (AR) continuum runs from virtual content that is clearly overlaid on a real environment (assisted reality) P.1320
to virtual content that is seamlessly integrated and interacts with a real environment (mixed
reality).

Virtual Reality An environment that is fully generated by digital means. To qualify as virtual reality, the virtual ITU-T
(VR) environment should differ from the local environment. P.1320
