virtual worlds, like Ariana Grande or Travis Scott have held concerts and
you can watch them, they are fun.
Other well-known types of virtual worlds are Fortnite, Warcraft or
Minecraft. A virtual world is a community that is built and maintained
digitally. To achieve the state of the metaverse that we aspire to go,
which is blurring the boundaries between the mutual and physical world,
we need to go through three-phases of digitalisation. The first phase is
called digital model. A digital model is virtual representation of a physical
entity. Here, the physical and digital world, they don't really communicate
with each other. The second phase is called a digital shadow. A digital
shadow is a virtual representation of a physical entity which is impacted
by the physical entity. There is no impact coming from the virtual world to
the physical world but there is impact coming from physical to the virtual.
Finally, the third one is called the digital twin, this is what dynamic virtual
representation would look like. The physical and digital world would
impact each other.
By going through each phase of digitalisation, we will have more
opportunities to engage with other people. For example, right now we
have avatars, with we can communicate through avatars in the virtual
worlds and research is going on around about how to enhance the
physical image and body language of avatars. Just the conversation flows
more naturally.
Another type of keeping in touch with other people in the virtual
world is holograms. In Sydney Jewish Museum, there is an exhibition
called the Reverberations: A Future of Memory, where three Holocaust
survivors have sat down and answered 1100 questions, so you can go and
discuss with them their experience and just talk to them within their
holograms.
Back to the original question, we wanted to see how we can
