IMI is seeking a grant to develop a virtual world that will work to prevent teen smoking. The world will allow the user to enter a human body, observing internal organs and bodily functions. By creating two versions of the environment, users will be exposed to the inside of both a healthy body and a smoker's body. Combined with education, teens entering this environment will witness the damage that cigarettes inflict upon internal organs. By experiencing this immersive environment, teens will be able to internalize the dangers of smoking. This program hopes to discourage teens from beginning to smoke, and will encourage those that do to stop.
