U.S. researchers are designing software that will allow doctors to carry out simulated surgery using the Nintendo Wii console's novel control system. The motion sensors in the wireless "Wiimote" allow game players to direct on-screen action by waving it about and pointing it at the screen. Some experts believe the software could help surgeons improve their skills by practicing at home, and play an important role in the medical education in the developing world where there is less access to expensive virtual training tools.
