Remember all that talk about the Wii Vitality Sensor that Nintendo was going to release back in 2009? Well if you don’t, who can blame you, as it’s been a while since Nintendo’s 2009 E3 event when the Vitality Sensor was first shown to the public. And even if you don’t remember it, Nintendo still does, as according to a story on Eurogamer today, Nintendo CEO Satoru Iwata told investors at the results Q&A session in Japan last week that Nintendo still wants to release the Vitality Sensor, but that it still needed more fine-tuning to iron out some problems. According to Iwata, the fact that the device is used to monitor an individual’s stress and nerves as they play their Wii games is actually what has caused the problems, what with every human being different and all. “This is a totally new type of entertainment, and there are large individual differences in the biological information of humans. For example, if it was acceptable that only 80 per cent of the users thought the result was natural, then we could propose this to consumers right now. However, we are aiming for a level of quality in which 99 per cent of consumers feel comfortable, and that is why this project is taking time to complete.” Iwata promised during the Q&A that the Vitality Sensor would eventually see the light of the day, although he didn’t give a specific date.
