Digital Shadows as the aggregation, linkage and abstraction of data relating to physical objects are a central vision for the future of production. However, the majority of current research takes a technocentric approach, in which the human actors in production play a minor role. Here, the authors present an alternative anthropocentric perspective that highlights the potential and main challenges of extending the concept of Digital Shadows to humans. Following future research methodology, three prospections that illustrate use cases for Human Digital Shadows across organizational and hierarchical levels are developed: human-robot collaboration for manual work, decision support and work organization, as well as human resource management. Potentials and challenges are identified using separate SWOT analyses for the three prospections and common themes are emphasized in a concluding discussion.
When thinking of textile interfaces, these are often imagined as being integrated into clothing. Whilethis is the most prominent use of fabric, we present a standalone interface that builds on the natural set of interactions a piece of fabric affords, and that is feasible for industrial production. By integrating stitched patterns made of conductive thread into a square piece of fabric, we are able to sense estab-lished connections within this pattern and map these to a model how the cloth is folded. An integratedmicrocontroller tracks these connections and communicates them as two-dimensional continuous value changes to a host application. We present the technical construction of our prototype, a particular clip-on technique to establish the connection between fabric and electronics, and first insights into recogniz-ing different grip gestures.
Textile controls so far, have mostly been envisioned to be integrated to clothing. In our environment, however, much more textile interaction surfaces are available. In this paper, we present a capacitive textile sensor, seamlessly integrated into a motorized curtain. While the basic functionality is simply to open and close the curtain, its design allows a much richer gestural interaction.
The future of industrial manufacturing and production will increasingly manifest in the form of cyber-physical production systems. Here, Digital Shadows will act as mediators between the physical and digital world to model and operationalize the interactions and relationships between different entities in production systems. Until now, the associated concepts have been primarily pursued and implemented from a technocentric perspective, in which human actors play a subordinate role, if they are considered at all. This paper outlines an anthropocentric approach that explicitly considers the characteristics, behavior, and traits and states of human actors in socio-technical production systems. For this purpose, we discuss the potentials and the expected challenges and threats of creating and using Human Digital Shadows in production.
