It don't mean a thing (if you can't track your swing)

Here's another motion-sensing start-up at Launch--Zepp. It's showing off Golfsense, a high-resolution motion tracker that records your swing in 3D and sends the data to your iPhone. Hackers (you know what I mean) will love this. It measures the consistency of your swing, shows you the clubface's track in a rotatable 3D image, and compares your handiwork to advice from golf coaches.

Unlike Greengoose, which only grossly tracks motion but can monitor your juice bottles, Golfsense is highly specialized to track fine-grained and very fast motion. Doing a golfing app with this technology is smart; this is a group of users who eat up picky, specific critiques on how they move. But future apps are also interesting, and not just in sports. The service could be used for medical rehab, for example.

It's interesting how data from the physical world is getting into the virtual, with services like the motion trackers shown off at Launch, as well as check-in apps like Foursquare. Of course I worry about privacy with the growth of tracking services, and insurance companies getting hold of this data, but for now, if you're a golfer, definitely check this out.
