The Digital Twin in Human Activities: The Personal Digital Twin

Abstract

With the 5G era evolving continuously towards maturity, ICDT deep convergence is accelerating, and so is the transformation of our society. Simultaneously, advanced exploration of the 6G vision where a new era of “Digital Twins, Pervasive Connectivity with Ubiquitous Intelligence” is emerging. We expect the physical, biological, and cyber worlds to be fused together via the new generation of intelligent connectivity. In such an era, everyone may have his or her own Personal Digital Twin (PDT) in the cyber world. Such a PDT may include the person’s external appearance, as well its internal organs and tissues. The PDT may be used to predict human health, behavior, and emotion in advance of developments warranting concerns or requiring attention, and even simulate people’s thoughts to realize spiritual immortality in some extreme sense. Our PDTs can be transmitted to any place in the world in real time through the pervasive network for various activities, be it attending a concert, enjoying the beaches and sunshine of the Maldives, or hugging family members and friends that are oceans apart. This chapter will examine the usage scenarios of PDT, the challenges and the wide varieties of technologies involved, encompassing PDT information acquisition, transmission, processing, and presentation. In particular, wireless body area networks (WBANs) and multi-source data fusion will be highlighted. PDTs will rely on the joint development of many technologies from multiple disciplines, such as brain-computer communications, molecular communications, synesthesia interconnection, AI, and intelligent interaction. We will present a variety of health-care applications as part of a very early-stage list of accomplishments in our PDT platform development as well as the outlook of PDT related developments across the globe.
