Using games to increase exercise motivation

In recent years, there has been significant work in integrating physical activity into video games. One goal of this work has been to help motivate sedentary people to be more physically active. Konami's Dance Dance Revolution and Nintendo's Wii Sports have shown that exercise games can be both fun and commercially successful.
 To date, however, there has been little attempt to investigate what properties of exercise games will help motivate sedentary people to start and continue exercise programs. This paper reviews the literature on exercise motivation and derives from it requirements for computer-aided exercise games. The paper then introduces the new Life is a Village exercise game, and uses it to illustrate how these requirements can be met.
