Truth and Love Telling Eyeglasses

The company showed plain sunglasses outfitted with the technology at the 2004 International CES in Las Vegas earlier this month. The system used green, yellow and red color codes to indicate a "true," "maybe" or "false" response. At its CES booth, V Entertainment analyzed the voices of celebrities like Michael Jackson to determine whether they were lying.

Besides lie detection, Watson said, the technology "can also measure for other emotions like anxiety, fear or even love." Indeed V Entertainment offers Pocket PC "love detector" software that can attach to a phone line or work from recorded tapes. It's available for download at www.v-entertainment.com. Instead of color-coded LEDs, a bar graph on the display indicates how much the caller to whom you are speaking "loves" you. V Entertainment claims the love detector has demonstrated 96 percent accuracy. A PC version is due next month.
