Nintendo could be about to reveal its plans for the bizarre Wii Vitality Sensor, after announcing a press event with the American Heart Association.
The invite for the May 17 event doesn't offer any indication as to what its announcement might be, but the Vitality Sensor - which measure the pulse of Wii players - seems very likely.
Nintendo boss Satoru Iwata said at last year's E3 that he reckons the device has heaps of potential, with the possibility one day for it to help you sleep with special software.
"Everyone under pressure in our stressful society could use this to help us relax in a videogame. Videogames could be made for people to unwind or even fall asleep," he said.
Nintendo's previously said it will release the Vitality Sensor in 2010.
