Experts are imperative for supporting expertise development in apprentices but learning from them is difficult. In many cases, there are shortages of experts to train apprentices. To address this issue, we use wearable sensors and augmented reality to record expert performance for supporting the training of apprentices. In this context, we present the conceptual framework which outlines different instructional design methodologies for training various attributes of a task. These instructional design methodologies are characterized by their dependencies on expert performance and experts as model for training. In addition, they exploit the affordances of modern wearable sensors and augmented reality. The framework also outlines a training workflow based on the 4C/ID model, a pedagogic model for complex learning, which ensures that all aspects of conventional training are considered. The paper concludes with application guidelines and examples along with reflection of the authors.@en

The WEKIT.one prototype is a platform for immersive procedural training with wearable sensors and Augmented Reality. Focusing on capture and re-enactment of human expertise, this work looks at the unique affordances of suitable hard- and software technologies. The practical challenges of interpreting expertise, using suitable sensors for its capture and specifying the means to describe and display to the novice are of central significance here. We link affordances with hardware devices, discussing their alternatives, including Microsoft Hololens, Thalmic Labs MYO, Alex Posture sensor, MyndPlay EEG headband, and a heart rate sensor. Following the selection of sensors, we describe integration and communication requirements for the prototype. We close with thoughts on the wider possibilities for implementation and next steps.
