My two cents on the metaverse: why it is important and how to build it using latest computational science-based tools

The social angle of the metaverse

Anna Wiener’s in her recent article [2], is defining the term based on different perspectives of Key Opinion Leaders (KOLs):

The economic angle of the metaverse

The World Economic Forum is actively studying the imminent huge economic potential [3]:

The technological angle of the metaverse

Caecilia, d’Anastasio provided a definition based on the major enabling technologies of the metaverse, namely virtual and augmented reality (VR/AR) [4]:

Why the metaverse is more important than you can imagine?

An excellent recent publication [6] by my colleague Prof. Riva, describes with clear neuroscientific evidence, how the metaverse can essentially transform our autobiographical memories and effect our very own brain cognitive functions.

How the metaverse will be eventually built and sustained?

The cornerstone enabling technology as well as main interface for the metaverse to my opinion is virtual reality and its siblings (AR, MR etc.) along the Virtuality continuum by Milgram and Kishino [8] or what collectively the industry defined with the umbrella term XR, ‘extended reality’ by the XR Safety Initiative [9]. It is quite interesting they are also referencing one of our early published works on inside-out AR tracking as a means for 6 degrees-of-freedom head tracking in VR, well before this idea became standard in the field [10].
