Towards Human Digital Twins for Improving Customer Experience
Applications of digital twin (DT) technology have gained momentum in IS research and cognate disciplines. Several studies have documented how DTs create value in contexts such as manufacturing or smart cities through virtual monitoring and decision-making. While these contexts benefit from DTs of products or production steps, this research is the first to investigate the potentials of human DTs to improve customer experience (CX) (i.e., customer twins). Drawing on a structured literature review, we derive new conceptualizations of DTs as (i) virtual mirrors that depict a physical entity and its interactions in virtual space, and (ii) virtual orchestrators which extend the virtual mirror by also simulating potential virtual interactions. These new conceptualizations, by applying them to human DTs, enable us to discuss DT’s implications to approach current CX potentials. The results of the discussion indicate that human DTs can support CX management to improve CX throughout the whole customer journey
Digital Twins for Patient Care via Knowledge Graphs and Closed-Form Continuous-Time Liquid Neural Networks
Digital twin technology has is anticipated to transform healthcare, enabling
personalized medicines and support, earlier diagnoses, simulated treatment
outcomes, and optimized surgical plans. Digital twins are readily gaining
traction in industries like manufacturing, supply chain logistics, and civil
infrastructure. Not in patient care, however. The challenge of modeling complex
diseases with multimodal patient data and the computational complexities of
analyzing it have stifled digital twin adoption in the biomedical vertical.
Yet, these major obstacles can potentially be handled by approaching these
models in a different way. This paper proposes a novel framework for addressing
the barriers to clinical twin modeling created by computational costs and
modeling complexities. We propose structuring patient health data as a
knowledge graph and using closed-form continuous-time liquid neural networks,
for real-time analytics. By synthesizing multimodal patient data and leveraging
the flexibility and efficiency of closed form continuous time networks and
knowledge graph ontologies, our approach enables real time insights,
personalized medicine, early diagnosis and intervention, and optimal surgical
planning. This novel approach provides a comprehensive and adaptable view of
patient health along with real-time analytics, paving the way for digital twin
simulations and other anticipated benefits in healthcare.Comment: 6 page
Human Digital Twin: A Survey
Digital twin has recently attracted growing attention, leading to intensive
research and applications. Along with this, a new research area, dubbed as
"human digital twin" (HDT), has emerged. Similar to the conception of digital
twin, HDT is referred to as the replica of a physical-world human in the
digital world. Nevertheless, HDT is much more complicated and delicate compared
to digital twins of any physical systems and processes, due to humans' dynamic
and evolutionary nature, including physical, behavioral, social, physiological,
psychological, cognitive, and biological dimensions. Studies on HDT are
limited, and the research is still in its infancy. In this paper, we first
examine the inception, development, and application of the digital twin
concept, providing a context within which we formally define and characterize
HDT based on the similarities and differences between digital twin and HDT.
Then we conduct an extensive literature review on HDT research, analyzing
underpinning technologies and establishing typical frameworks in which the core
HDT functions or components are organized. Built upon the findings from the
above work, we propose a generic architecture for the HDT system and describe
the core function blocks and corresponding technologies. Following this, we
present the state of the art of HDT technologies and applications in the
healthcare, industry, and daily life domain. Finally, we discuss various issues
related to the development of HDT and point out the trends and challenges of
future HDT research and development
Digital Twins:An enabler for digital transformation
Digital Twins are a virtual representation of anything of value for an organization that create a link between the real and virtual worlds by a continuous bidirectional data/information exchange. In this chapter we present the origins of the concept and how it evolved with the advent of new technological trends. In addition, we describe the main characteristics of a Digital Twin, the benefits of its use, and real-world examples of the usage of digital twins’. Finally, the challenges for its adoption, and the elements to be considered for managing the quality of the Digital Twin are presented to give a complete overview of this new technology.Full book available: https://www.rug.nl/gdbc/the-gdbc-book
Networking Architecture and Key Technologies for Human Digital Twin in Personalized Healthcare: A Comprehensive Survey
Digital twin (DT), refers to a promising technique to digitally and
accurately represent actual physical entities. One typical advantage of DT is
that it can be used to not only virtually replicate a system's detailed
operations but also analyze the current condition, predict future behaviour,
and refine the control optimization. Although DT has been widely implemented in
various fields, such as smart manufacturing and transportation, its
conventional paradigm is limited to embody non-living entities, e.g., robots
and vehicles. When adopted in human-centric systems, a novel concept, called
human digital twin (HDT) has thus been proposed. Particularly, HDT allows in
silico representation of individual human body with the ability to dynamically
reflect molecular status, physiological status, emotional and psychological
status, as well as lifestyle evolutions. These prompt the expected application
of HDT in personalized healthcare (PH), which can facilitate remote monitoring,
diagnosis, prescription, surgery and rehabilitation. However, despite the large
potential, HDT faces substantial research challenges in different aspects, and
becomes an increasingly popular topic recently. In this survey, with a specific
focus on the networking architecture and key technologies for HDT in PH
applications, we first discuss the differences between HDT and conventional
DTs, followed by the universal framework and essential functions of HDT. We
then analyze its design requirements and challenges in PH applications. After
that, we provide an overview of the networking architecture of HDT, including
data acquisition layer, data communication layer, computation layer, data
management layer and data analysis and decision making layer. Besides reviewing
the key technologies for implementing such networking architecture in detail,
we conclude this survey by presenting future research directions of HDT
