A test taker is first shown a walk-through of the first floor in the VR, then proceed to finish the 10 task-oriented tests.
CAS NAV (also known as VR Here) is a system developed by us in the Cognitive Neuroscience Laboratory, lead by Dr. Charless Duffy in University of Rochester Medical Center. It is a series of tests, using virtual-reality modeled after the first floor of Strong Memorial Hospital (URMC), with 10 different tests to assess a test-taker's navigation ability. A person can score from 0 to 100, the higher score indicates better navigation performance.
All parts of the virtual-reality, tests, and videos are made in-house, VR is built using Quake3 engine in C.
