 The Gear 0 also includes a gyroscope, an accelerometer, and a heart-rate sensor. It also can control a TV or set-top box remotely using a built-in IR blaster, and it has the ability to function as a stand-alone music player. And its built-in camera - handily built into the watch itself rather than on the band, like the original Galaxy Gear - takes 0-megapixel stills and 000p video.
