Human digital twins in interaction design : from abstract to concrete

Abstract

Human digital twins are a promising tool for designers. Digital twins have long served as models of technical and cyber-physical processes. Human digital twins take such models and add interactions with human users. Thus, human digital twin models enable technology designers to model people interacting with technical artefacts. The conceptual structures of such models present numerous open conceptual problems. To clarify this issue, we designed an interaction model for such general abstract machines as Minsky's M-Machine. The abstract conceptual structure of this machine allows us to consider at a general level the interaction processes involved in constructing models of human digital twins. The M-Machine model could help designers construct solutions for concrete human digital twins for human–technology interaction processes.
