In this study, we introduce an authoring toolkit enabling both experts and trainees to record their actions in a virtual environment, streamlining the creation of training procedures and the evaluation of trainee actions. The toolkit was developed using two distinct methods: a state-based and an input-based approach. Within a virtual testing environment, we compared these methods across a range of interactions, focusing on three performance ...

Underground facilities are endangered by excavation work, since the mapping of a plan to the real construction site is error-prone due to wrong data, lack of training, or disappearing markers. While technical solutions for positioning exist, they lack accuracy in particular in densely built-up areas. This paper thus introduces an alternative system that relies on Google Street View geospatial data to determine the precise position for ...

This paper introduces a novel mixed reality (MR) remote guidance system for supporting laser alignment experiments. Replacing conventional laser safety glasses, a video see-through head-mounted display (VST-HMD) shields users from hazardous radiation. Nevertheless, the impact on human work performance when using a standalone VST system for laser alignment has not been fully explored. In this paper, we studied the effects of the MR guidance ...
