context of immersed multimedia, e.g., DT system, an adaptive
synchronization scheme is used to solve multiple channels of
communication. In addition, the outcomes in the studies [10]
have shown that adaptive synchronization does not require a
global clock due to its immunity to clock offset and/or clock
frequency drift. Therefore, it provides support for optimal
delays and buffering that are requirements to achieve the required quality of service of the said system.

A Glance into the Future
The DT of a human is a replica of a living person. It facilitates
the intake of sensory data and simulates conditions quickly,
understands what-if scenarios clearly, predicts results more
accurately, and outputs instructions to manipulate the physical world.

Preventive Medicine
The idea is now very achievable where a virtual representation of a human being would progress to the point where one
could look at their virtual self and visualize how they are doing in terms of their health and what is happening inside their
body: what illnesses could be preparing although the symptoms did not show yet, depending on what health choices they
have been making in the past. The DT would have all of the
necessary elements: medical record and health information,
weather, GPS, time, financial information, eating behavior,
sleeping information, workout data, etc., to infer the health
state of a person at a given point in time. For example, the personal history information includes the person's diet and this
can be achieved using advances in smart homes, including
smart kitchens, food recognition, etc. The personal information also shows how much they have been working out and
what their sleep habits are and sleep quality. For this data collection, technologies such as wearables and sleep tracking
devices can be used. This information could help health caregivers provide the right advice to their patients at the right
time, a big step towards preventive medicine.

Social Interactions and Dating
The popularity of dating sites is increasing; however, the information that each user provides to these sites might not be
accurate. This inaccuracy can happen due to the fact that users
need to manually input subjective information regarding their
personality. Some people might not accurately assess themselves and some others will simply enter false information for
unknown purposes. DTs can help us have a more accurate description of ourselves. With DTs on the web, people not only
will have information regarding their counterpart, they also
could simulate situations that will give them a better idea of
the person that they are dealing with. The final result will be
better matching, reduce the number of fake profiles, and predict the outcome of a future event.

want them to follow in interesting indirect ways with minimal
efforts. This usage will bring effective solutions, especially in
the current time where children are exposed to technology. For
example, if parents want to motivate their child to drink lots of
water, they could ask their DT to do that, so the DT simulates
this in real life. Also, they can use the DT as a representative
for their child so the DT looks good when the child behaves
well in reality. Also, the DT can help parents to track their children's behavior, friendships and other activities while they are
in school through their twin's behavior in the virtual world.

Digital Twin for Sport
The DT uses sensors to easily collect data in real-time. For
example, in football, the DT is built using the athlete's own
football data to help them understand the way they play,
practice and perform. It uses physical, physiological data, contextual and emotional data to create a digital football version
of them in real-time. The DT uses sensors to easily collect the
athlete's football data in real-time. Wearables, such as smart
watches, capture heart rate, step count and GPS location as
well as practice and performance data. Using AI technologies
such as machine/deep learning and other algorithms, we can
quickly analyze the football data in real-time to produce easy
to read reports that inform us about the play and practice performance and off-pitch activities. With custom knowledge, the
DT advises on what the athlete can change to improve overall
performance. The DT converges the data on a single platform
to give custom information and interaction through augmented reality, haptics, etc.

Final Remarks
The DT technology has already proved to be very beneficial
in the industrial processes and is gaining wide adoption by
companies worldwide. The potential of the DT is such that
its integration and deployment in smart cities for the benefit of citizens is becoming more of a necessity than a luxury.
Health and well-being are at the top of the list of domains that
can benefit from the DT technology. Social interactions, sports,
and memories can be also improved greatly. In the meanwhile,
challenges discussed in this article have to be solved as we
move towards this trending and highly promising technology.
