| An artificially induced limp is classic fieldwork from the "good ol days" of the Cold War. What I've read of gait recognition though is that it's not so much about identifying you, as identifying someone walking "suspiciously" in a given area. Or tracking a person where you can't see their face, based on their gait once recorded. However, I haven't yet been able to find any papers that describe gait recognition with a subject consciously modifying their gait. For example, when I'm stressed I tend to walk fast, but when I catch myself doing so, I will actively slow my pace down, and change the distance of my steps - like the old adage of "smiling makes you feel happy when you're not", I find deliberately slowing down my pace, and not taking such long strides, helps me calm myself - especially when combined with a focus on breathing. What I can't find is any discussion of how existing gait analysis algorithms handle an observed subject deliberately varying their gait. And what papers I can find on this are largely written by Chinese academics who don't find a 94% identification rate (leaving 6% false positive or negative) to be an issue, which I guess works in a totalitarian collectivist regime where an arrest on a false positive isn't considered a violation of human rights because, lol, human rights. Which brings me, verbosely, to the academics researching this. How do they incorporate improving the surveillance capabilities of an oppressive government into their personal mores? Do they take the stance that those doing nothing wrong have to nothing to be afraid of? |
