QoL will have nothing to do with gaming. It won't help them in the gaming scene. And as much as it pains me to say, if its a physical device at all outside of a wearable sensor, I doubt it will take off in the west. There are already fitness apps out there that cover many different things. Body building, weight loss, diet, general lifestyle etc. All of these things are things that Nintendo are not a world leader in.
As for the sleep sensor I think its intriguing technology. I think if they can work on the scanning better, it could be used in the medical field as a tertiary device. It apparently can track heart rate and breathing and the like.
