Sure, there's plenty of devices like the Fitbit that can track your movement and report on your general level of activity or laziness, but only Hitachi has what it's dubbed a "Life Microscope." That name apparently comes from the fact that the device is able to track your activity with more detail than other fitness monitors -- including, it seems, the difference between sitting and sleeping, and even the difference between eating or playing video games. That data is then naturally able to be transferred to a PC, and it also sounds like the Life Microscope could be incorporated into actual watches as well -- if it ever moves beyond the concept stage, that is.
