Towards the Human Digital Twin: Definition and Design -- A survey
It provides foundational clarity for developers in fields like healthcare and sports, but is incremental as a survey.
This survey addresses the ambiguity in defining Human Digital Twins (HDTs) and the lack of design guidance by proposing a cross-domain definition and eleven key design considerations to guide future developers.
Human Digital Twins (HDTs) are a fast-emerging technology with significant potential in fields ranging from healthcare to sports. HDTs extend the traditional understanding of Digital Twins by representing humans as the underlying physical entity. This has introduced several significant challenges, including ambiguity in the definition of HDTs and a lack of guidance for their design. This survey brings together the recent advances in the field of HDTs to guide future developers by proposing a first cross-domain definition of HDTs based on their characteristics, as well as eleven key design considerations that emerge from the associated challenges.
