Eye-based lie detection has long been the stuff of research and science fiction, but it's about to become a practical reality in the office. Converus is releasing EyeDetect, a hardware and software combo that helps companies find out if their workers are on the level. The system revolves around an SMI-made camera that monitors pupil dilation as well as the positions of the eyes and head. If you look shifty when answering questions, your supervisors will likely know within minutes. It's not a perfect system; Converus claims 85 percent accuracy, which could allow for occasional false positives. We'll know EyeDetect's real-world usefulness very soon, though, as it's launching in Mexico this April.
