The document discusses applications of virtual reality (VR) and augmented reality (AR) technologies. It provides examples of VR and AR hardware products and describes how VR and AR can be used for safety training, assembly and maintenance training, engineering and design, and conferences. Benefits highlighted include creating realistic interactive environments for training, visualization of technical processes, minimizing safety risks, lowering costs compared to traditional training, and enabling remote collaboration. The document also presents an example of an augmented reality application developed by Marcin Radomski for providing instructions on pneumatic cylinders.
