Effective Integration of Errors in Vocational VR/AR-supported Learning Processes

 

Synopsis

Currently, there is a lack of didactic concepts on how apprentices and trainers involved in apprenticeships and vocational education for industrial and skilled electrical and metalworking professions can effectively use errors in real work situations to learn. In most teaching and learning situations in vocational education and training, it is currently not possible for learners to make mistakes, as this can have negative consequences in terms of safety, efficiency, or environmental protection, for which trainers are responsible. For this purpose, a digital media solution is being developed, which uses augmented reality (AR) to virtually show the consequences of errors in operational tasks within a suitable learning concept.

Challenges

In order to master the didactic challenge of the effective use of errors in a company education process, we need a design-oriented didactic concept that follows a situated and competence-oriented curriculum. The didactic concept must state requirements for the design process of the FeDiNAR system used in an industrial-technical dual training structured learning process. The IAW uses ergonomic work analysis methods as well as surveys on didactic conditions to clarify the operational and didactic requirements for the AR system. Work processes documentations refer on modeling languages from business informatics, and integrate in a work in order to be able to describe and simulate sequences of actions so that these can be visualized using digital twins.

Goals

The goal of the FeDiNAR joint project is to develop and evaluate an AR-supported learning system with associated learning scenarios in order to use errors "made" by a learner for efficient individual skills acquisition. With the FeDiNAR system, learners can work on situated tasks in learning scenarios. Learners work with real machinery and can interact with them directly. However, some of the actions (and their effects) take place exclusively in the virtual world, so that, for example, a wrench forgotten on the lathe machine only flies through the workshop virtually, visualized by means of AR.

Methodology

Solutions already available on the market, such as AR glasses, a simulation environment for modeling, updating and simulating digital twins of humans and machines, as well as a software solution for interaction detection, will be combined in an application-oriented manner to also enable small- and medium enterprises and vocational schools to use this innovative learning system.

Results

As an interim result, a demonstrator based on a Fischertechnik industrial robot has been built as a machine. This machine can be used to understand the functionalities of the FeDiNAR system and to further develop it for real use cases. Based on the knowledge generated there, the FeDiNAR system will be implemented and evaluated for two real use cases of CNC turning and plastic injection molding.

 

Funding

The FeDiNAR project (funding code: 01PV18005A) is funded under the Digitale Medien in der beruflichen Bildung – Forschungsprojekte zur Virtuellen und Erweiterten Realität (VR/AR) in der beruflichen Bildung (VRARBB) program and supervised by the DLR project management agency.
