VI Fit is actually a video game research project at the University of Nevada, Reno. Modeled on the Wii, the participation in these games do not require lateral variety of vision. So, especially taking in consideration the needs of the visually impaired, these active video games will let them stay fit. These games might not need any vision, but these do require Wii remote controllers and a Windows PC with Bluetooth support or a USB Bluetooth dongle and these games can be downloaded for free at Vifit.org

The two new games called VI Tennis and VI Bowling are first of the several games that are yet to come. VI Tennis uses Wii tennis, but with audio and vibrotactile cues, instructing the players about when to return and when not to, the players can either play it against other player or even the computer. And, same is the case with VI Bowling, except that it has a motor learning feature. This project was led by Eelke Folmer and his team consisted of Tony Morelli, John Foley, Lauren Lieberman.
