Peter Robinson, a professor at Cambridge, got so fed up with how irritating his GPS device is that he set out to build a device that would understand his feelings of frustration. Here's what happened next.

Robinson heads up an emotional robotics group, which creates software that allows computers to recognize human facial expressions, tone of voice, and posture - translating them into one of hundreds of archived "emotional states." As a result, Robinson now has a robot who is sensitive to his feelings while he's driving - though you'll have to judge for yourself whether his emotion-recognizing robot is any less annoying than a GPS.
