Jacob Whitehill at UC San Diego's Jacobs School of Engineering has demonstrated a proof of concept that allows his facial expressions to speed-up and slow-down video playback. Pretty sweet. But we're more interested to hear that his project is part of a larger effort at the UCSD Machine Perception Lab (gulp) to use automated face recognition to "make robots more effective teachers." We can see the future now...

Human: (frowning)
Robot: Aw, my meat bag is sad, I will now give it a hamburger and turn on Golden Girls.

Fortunately, human teachers who've somehow missed out on the billions of years of biologically evolution required to recognize the "oh face" can take advantage of this research as well. See a video demonstration of that after the break, face-controlled video here.
