  Photo-realistic avatar is a modern term referring to the digital asset that
represents a human in computer graphic advanced systems such as video games and
simulation tools. These avatars utilize the advances in graphic technologies in
both software and hardware aspects. While photo-realistic avatars are
increasingly used in industrial simulations, representing human factors such as
human workers psychophysiological states, remains a challenge. This article
contributes to resolving this issue by introducing the novel concept of
MetaStates which are the digitization and representation of the
psychophysiological states of a human worker in the digital world. The
MetaStates influence the physical representation and performance of a digital
human worker while performing a task. To demonstrate this concept, this study
presents the development of a photo-realistic avatar enhanced with multi-level
graphical representations of psychophysiological states relevant to Industry
5.0. This approach represents a major step forward in the use of digital humans
for industrial simulations, allowing companies to better leverage the benefits
of the Industrial Metaverse in their daily operations and simulations while
keeping human workers at the center of the system.
