That's a good idea - I've thought about putting smart phones on the ankle but not stopped to think that the pocket is sufficient. Now, that said, it's hardly simple to get that signal off (via bluetooth I assume) across several platforms and read into a micro controller. But I like that kind of problem more than I like the mechanical engineering and design issues of the sensor ring, so I'll definitely give it a closer look. Thanks!
