Verifying the design of a mechanical product typically requires a physical mockup. Virtual reality can avoid this by letting workers experience real-size design inspections avoiding to waste time and money to produce physical and potentially still faulty assets. Multi-user environments have been studied to verify the utility of virtual reality in performing design reviews for maintainability. The main features required in such software have been determined. A systematic literature review on the state of the art usages of virtual reality for design inspections and industrial training completes the thesis
