recognition. Its benefits are the possible interactions such as pointing, lifting the thumb up
and grabbing objects.
To ease the porting process for future different platform, the Unity 3D game engine was
adapted for the software development. The VR-Mine application is composed of several
modules (i.e. Game Objects) within a Unity scene. The scene development is intensively
based on the provided Oculus Rift software development kit. The scenes require visualising the mine as close as possible to reality to realistically depict actual colours, textures and
geometry of the walls and faces. In order to do so, photogrammetry in combination with a
modelled environment is being used (see Figure 5).
3.3 Didactic concept
The VR-Mine is designed interactively and offers gamification-based learning. In this way,
contents are conveyed very close to professional practice and self-determined learning is
supported. Due to integrated explanations, the students can use the VR-Mine during their
self-study phase.
