This is a compilation of recorded virtual walk-throughs at Saint Luke's Brain and Stroke Institute. We had doctors, nurses, anesthesiologists, and project managers walk through, make functional changes, and provide collaborative insight all in a single day. The sense of immersion and presence can only experienced with an HMD. However, in this video you can see how easy it is for end users to change the environment as to their personal preferences, which allows architects and project managers a make necessary changes before anything is built!
