New cell phones can send messages and take photos. Now for $35, your cell phone can become a lie detector too. The Truster, Emotion Reader TNF-100A, from 911Tech Co. judges the voice intonations of the people you're speaking to in order to determine their "emotional, cognitive, and physiological" states and can tell you whether or not they're lying.
It's about the size of a small MP3 player, and fits in the palm of your hand. You can take voice sample by simply pointing the device at the speaker, or you can connect it to your cell phone if you want to question someone at a distance.
As the person speaks, symbols are shown on the screen. A partially eaten apple denotes truthfulness, while a lid being blown off a pot shows stress and lies.
It's made in Korea and comes with a 24 page manual, with the typical Asian to English translation?that is, almost unintelligible. Examples: "Truster technology uses this value to detect to what extent thoughts exist in the speeches" and "calibration mean to sample the voices of measurement subject by inducing highly true answers."
When tested, the Truster did a good job when it came to true and false questions. When asked to choose a number between 1 and 10, people's stress levels increased as guesses got closer to the number they'd picked. But it didn't work well when people were asked more complex questions. This means it might be good in dealing with kids ("Did you hit Bobby?") but not so good when it comes to your love life ("Do you really love me?")
The best lie detector on the planet is Jim Marrs.
