The trick of developing a computer that can understand faces was not to try to replicate the elusive mental processes human beings use to make judgments about one another. Despite the computer's ability to calculate the trajectories of spacecraft or pick the next move in a chess game, the...
To get around this, the Salk researchers based the design of their face-recognizing computer on the one thing all computers do well: acquiring, storing and analyzing masses of information at lightning speed. In the 1970s, psychologist Paul Ekman and his colleagues at the University of California, San Francisco, developed...
To help catch these actors, Bartlett scanned pictures of faces into the computer and wrote instructions that taught the machine to recognize six of Ekman's coded movements: the fleeting grimace or scowl, for example, that may precede a liar's counterfeit smile. When the computer was later presented with...
Of course, identifying facial twitches is not the same as reading states of mind, particularly when the computer can make sense of only half a dozen expressions. But the newly trained machine should get a lot smarter in the not-too-distant future. In the next round of experiments, the...
Where the technology could go from there is difficult to say, but Sejnowski anticipates big things. Ekman often used videotapes to gauge the emotional states of subjects, once detecting a brief flicker of sadness in the face of a patient who later turned out to be suicidal. A computer like...
