Abstract
Operator 4.0 has to deal with a vast amount of product variants and production data especially within the mass customization paradigm, high mental demanding tasks, and smart production systems. Technologies capable of supporting his training and his work become fundamental, such as the extended reality (XR). Its increasing use in industrial applications, however, opens up new challenges related to interface and interaction design, which can determine the success of both the use and development experience. The lack of guidelines for designing interfaces for mixed reality (MR) applications is what this paper aims to address. Design requirements for MR interfaces are presented and applied in the context of operator training in wire harness activities. Different interaction modes and user interfaces have been developed to evaluate the most suitable and user-friendly one for the operator. A pilot test was conducted to assess the applications’ usability and potentialities with satisfactory results.
