Putting product virtually in your hands.
The trouble with physical prototypes is that they are in themselves not real. They are simulated models of something that will eventually be made using different techniques and different materials than those used for the prototype. Even the best model makers can't disguise the smell of paint or the need to handle with care.
A prototype to prove usability and function is one thing, but when it comes to how a product will look and behave there is no replacement for a CGI virtual prototype. Whether it is viewed on VR goggles or a standard screen, the viewer will receive a clear understanding of what the product is about without the functional inadequacies of a physical model.
A virtual prototype, unlike its physical predecessor, can be copied and exported across the world to any audience by attachment to an email. Sharing prototypes with an audience has always been a stressful experience; the fear of poor handling by less aware recipients is inevitably a concern. Sometimes, so much so that products at trade shows or consumer tests can often come with a ‘do not touch’ policy. In contrast, the virtual prototype can be viewed by anyone with the peace of mind that they won't break it.
