We have already mentioned the role of virtual reality in product development, however, the application does not have to be limited only to development but can be useful in both the testing of the products and services.
Virtual reality can be highly effective in the area of product testing, for example, a large hardware store in the United States that had furnished a real room that could be painted with virtual paint, in this way customers could see exactly what effect the colour or material would have on the wall.

Products and services can be presented to testers in various configurations with the added ability to adjust the circumstances for each test. Subjective perception will play an important role in this type of testing, research has shown that the taste of a standard cookie changes when someone with VR glasses sees added visual elements. You can also buy a RealWear HMT-1 smart glass for this purpose For example, users were asked to eat a brown cookie after seeing it in a virtual world, most reported the cookie tasted like chocolate with the syncing of virtual reality headsets.
