> Surely biometrics in all sorts of shapes and forms comes with it's own issues and shortcomings. Indeed. A behavioral biometric like this is probably most similar to gait recognition (identifying someone by they way they walk). It's slightly better than a 'soft biometric' like skin color and gender, but not good enough for any type of large scale deployment. Usually when researchers show this stuff it's more or less for novelty. With that in mind, there really shouldn't be a 'bigger vision' because recognition rates are usually not good enough to merit anything other than an occasional paper.
