Invisible Motion & Silent Sounds

Michael Rubinstein gave a Ted Talk recently about a new image processing method that allows standard video to be analyzed in such a way that allows near imperceptible movements to be detected and visualized via an amplification process. Minute color changes in the pixels of a video can give them enough data to visualize someones pulse or even detect vibrations created by sound that can then be used to recreate those sounds. The obvious practical application of this is a paranoia inducing increase in the efficiency of surveillance technology. Beyond that though, I’m interested to see where this tech could lead that might be beneficial to the marketing industry. Would user testing for interface design benefit from a non-intrusive means of measuring someones heart rate? Could the data be combined with other sources to determine the truthfulness of responses during user surveys? Or is all of this simply not worth the stepping onto the slippery slope that this technology represents?
