The American Heart Association is funding a student project to develop a CPR certification program that uses the Nintendo Wii:
A biomedical engineering professor at the University of Alabama at Birmingham envisioned a program for home computers that could sync via wireless with the Wii remote, and train users on proper resuscitation of people who have suffered cardiac arrest. The students hope to make the program available for download this fall, free of charge, on the American Heart Association's website.
