Interest is raising around extended reality training systems (XRTSs), which started to be considered as a credible option to train companies' workforce. Even though there is a growing body of literature on best practices and techniques to be adopted for teaching individuals how to perform a variety of operations (e.g., for assembly and maintenance procedures), there are also training situations which have gone mostly unexplored yet. In this paper, we propose and evaluate three different metaphors to face the key challenges associated with training procedures involving parallax-dependent tasks, i.e., tasks in which the instructor needs to make the trainee reach a target observation point and guide his/her attention towards a given point of interest at the same time. Effects observed through a user study that was run in a testbed environment indicated that metaphors based on 3D avatars and frustum visualization can provide important advantages over video-based techniques.

The use of VR in training groups for wind turbine engineers can cause didactic and practical problems. Integrating the whole group into the lesson and retaining attention and motivation while only one or two trainees wear a VR head mounted display (HMD) can be challenging for the trainer. Whereas VR HMDs isolate the users, engineering on wind turbines is a group effort. The problem is exacerbated when trainees need to use remote access to participate in the lesson, as can be the case under pandemic restrictions. We propose to use methods from asymmetrical game design and constructivist didactics to integrate participants without VR headsets into VR trainings for engineers.
Immersive Virtual Soft Skills Learning and Training of Employees: A Scoping ReviewTone Lise DahlSINTEF AS, Norway

Soft skills training is considered important for employees to be successful at work. Several companies are offering immersive virtual soft skills training with head-mounted displays. The main contribution of this paper is to provide an overview of the research literature within the field of using immersive virtual soft skills learning and training of employees. The results of this preliminary scoping review show that there is a lack of research literature and empirical studies within this topic.
