Kokoro Scanner – A Japanese High-Tech Toy That Lets Others Know If You Are Lying or Telling the Truth

The Kokoro Scanner (Heart Scanner) is a high-tech Japanese invention that can spice up classic party games such as ‘Truth or Dare’. It is a lie detecting device that is worn on the forehead and changes color to indicate the truthfulness of a person’s responses.

Created by Tokyo-based toy company ‘Takara Tomy’, the scanner works a lot like a polygraph machine – it monitors the pulse using infrared rays. So when you make a person wear it, it first monitors their heart rate to establish a baseline. Then, you ask them a question, the wearer responds, and the device monitors the heart rate once more to compare it with the baseline.

It then flashes green if the person’s pulse is normal indicating that they’re telling the truth, yellow if they might be lying, and red if they are lying for sure. Because the light is attached to the person’s forehead, they won’t be able to tell what color is flashing while they’re being interrogated with all sorts of embarrassing questions.
