# Development and Evaluation of Training Scenarios for the Use of Immersive Assistance Systems
## 6 Conclusions and Further Research
According to the current state of research, this type of error has been significantly underrepresented to date. Nevertheless, the effect of training should be consciously taken into account as a disruptive influence when assessing the potential for the productivity of the human-machine interface. This leads to the conclusion that it is not the design of the assistance system that may be inadequate but the training scenario that has not yet been effectively implemented. This research topic is particularly relevant to the operationalisation of the so-called industrial metaverse and could be one of the key factors in the productivity paradox. Moreover, it is important to investigate whether these implications are also valid for new generations of immersive headsets, such as Meta Quest 3, Apple Vision Pro, and other future HMDs.

The explanations of the various specific functions of an AR application must be available in separate, individually accessible video tutorials. This will clearly show learners which function is described in the tutorial. Care must be taken to ensure that the contents are formulated. This is because a tutorial must provide users with training content that is as precise as possible ([59]). In addition, excessively long tutorials can lead to cognitive overload. Furthermore, individually accessible videos offer the possibility of completing the training step by step and being able to try out key functions again at different entry points.
