Nintendo wants to watch you sleep

Nintendo has unveiled new details about its "QOL" platform, which stands for "quality of life" and includes a line of health-focused devices. The first will be a bedside sensor that tracks your sleep, sends the data up to the cloud for analysis, and produces suggestions to help you get more rest.

It's a strange move for the legendary gaming company. But seemingly strange moves have paid off for Nintendo in the past.
The most famous recent example is the Wii. While Microsoft and Sony pushed technology's limits to produce consoles with high-definition graphics and robust online features, Nintendo built an underpowered machine with a quirky name.
