The humble Wii has been a lot of things in its lifespan beyond a simple gaming machine. It's become an alternative exercise centre, dance studio, artist's easel and, of course, a games console. The Wii Remote, meanwhile, has been possibly the most creatively-used game controller in the industry's history, with its motion capabilities giving it a variety of applications. It's now being used as a medical device, showing that Nintendo really can make people feel better.
That's a slight distortion of the truth, but Wii Remotes are being utilised as a tool for diagnosing an eye disorder. Ocular torticollis is an eye disease that causes children to have an abnormal head position, and to diagnose the issue doctors are required to gather data on a child's head movements, which isn't always an easy task. It's been reported in the Investigative Ophthalmology & Visual Science journal that two Wii Remotes can be used to track the movement of the head in real time, sending results to a computer via Bluetooth.
The image in this article shows how the setup works, and is possibly the most elaborate use of Wii Remotes that we've seen so far.
