Do your research
"...what Sandler calls "gait biometrics," a fancy term for identifying an individual based on signals transmitted from his feet...new dynamic biometric profile.
"Each person's feet offer a different signal. Supposedly, anyway, since Sandler doesn't have any research to back up the claim that any person's gait is constant enough to serve as a profile, and different enough from others' to uniquely identify him..."
Gait biometrics is a recognised field of study. It's not "finished" yet (then, neither are iris and signature recognition, and fingerprinting might not be quite as infallible as the legal and enforcement professions believe), and it might not make it out of niche fields of application, but to call it "new" or imply that Sandler is some sort of lone crackpot working on a bizzare idea is frankly shockingly poor journalism.

There's this thing called the World Wide Web. It's really useful now they've invented decent search engines.
The completely ridiculous notion that you *should* have been poking fun at is that, to be widely useful, this fellow's gait biometrics has to be installed in every pair of footwear sold on the entire planet.
