From emaxhealth.com:

Early and ongoing research suggests that “walking” through a Virtual Reality Grocery Store can benefit people with balance disorders.

The world’s only Virtual Reality Grocery Store, based in the Department of Otolaryngology at Pitt and UPMC, is like a life-size video game that projects 3-D, moving images of a grocery store onto three screens which surround a real shopping cart on a custom-built treadmill. A person operating the shopping cart can control his or her own speed and direction of travel while walking up and down aisles that display realistic-looking products.

The store has 18 aisles, each with an increasing level of difficulty. Easier aisles display larger products, like paper towels, while the more challenging aisles contain smaller products, like canned goods or tiny bottles of medicine.
