Our paper presents an approach to automatically detect and transcribe basic human motions in VR by means of the Methods-Time Measurement (MTM) system. MTM is a predetermined motion time system that consists of a list of predefined basic motions and the mean time values corresponding to those motions. This system is used to analyze manual workplaces. Currently, the MTM analysis is conducted manually. The working process that needs to be ...

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 ...

User safety is a concern in the laser laboratory. Users must concentrate on small surfaces by watching telescope-generated images displayed on the screen to conduct measurement. Through a mixed reality head-mounted display (MR-HMD), they see the real world while being physically separated from hazardous laser radiations and can view telescope images on the HMD at the same time. In this poster, we conducted a comparative analysis of an ...
