Room scale VR can replace expensive scale physical mockups. Here’s a case study on how one hospital used VR in their design process:
Working with Cincinnati Children’s Hospital, 80+ medical professionals tested dozens of design options during a 3 day VR workshop with Simon Manning, formerly at ZGF Architects. The hospital and designers received comprehensive and well-informed feedback in days instead of weeks. Using a VR mockup, the hospital saved the cost and labor of making a physical mock-up which would have involved 100’s of pounds of foam and cardboard and days of labor (savings approx. $45,000).
As an added bonus, this enabled the hospital to run iterative way-finding studies with prospective patients in a virtual simulation of the clinic.
