Nintendo has patented a new sleep tracking device that will monitor your sleep and even produce pleasant scents. In typical Nintendo fashion, the device would represent a fresh approach to the growing sleep tracking market with a host of new features. According to the patent, the device could stream relaxing images to your ceiling using a built-in projector (does the sheep mini-game count, anyone?), as well as your previous night's sleep monitoring information.

It has a detachable element (which looks like a phone) that will track your activity throughout the day and sync data to the base station if it's nearby. The patent was filed last September and was recently made public (thanks, Japanese Nintendo). The sleep tracker may never come to fruition, of course, but Nintendo clearly believes it's an idea worth protecting.
