VR / AR
Virtual Reality
VR goggles present the user with an artificial environment without any reference to reality.
The VR glasses have two screens, one for each eye, on which the digital content is displayed. The VR goggles also capture the user's movements and thus create the feeling (immersion) of actually moving within the virtual world.
BIM models can therefore also be intuitively controlled and experienced by users with no prior technical knowledge. This is the greatest added value of this technology in the AEC sector, alongside the realistic feeling of space when walking through 3D models.
Augmented Reality
Digital content is presented to the user as an overlay in the context of the real environment.
This creates a digitally "enriched" (= augmented) reality.
This can be done either on a smartphone/tablet by superimposing it onto the live camera image or using special glasses that project the content onto the lens surface in the user's field of vision.
The link between digital BIM models and reality - on the construction site or in operation - results in numerous potential applications for the use of this technology, above all the visualisation of site-related data from planning, construction site or operation.
