I actually carry a Fitbit. You guys know the Fitbit, right? It’s just a simple 3-axis accelerometer. We like these things because they don’t have any – well, I won’t go into that [laughter]. What happens is, they discovered that just simply by looking at the data what they can find out is with pretty good accuracy what your gender is, whether you’re tall or you’re short, whether you’re heavy or light, but what’s really most intriguing is that you can be 100% guaranteed to be identified by simply your gait – how you walk.
Now this could be a really good thing. Think about this as a security app. If you’re walking along and you want to access your bank code, maybe it could become simplified because they can with absolute assurance know it’s you by your gait trying to do something with your bank. On the other hand, if you don’t want to be found or you want to protect yourself, maybe you don’t want to have somebody know what your gait looks like so they can figure out where you are at all times.
