MAKE is now selling a do-it-yourself kit that’s a combination mood ring and lie detector. The “Truth Wristband” is a piece of jewelry that monitors your internal state, and broadcasts it to the world via color changing lights. The video below shows it in action.
A wearable device that dynamically reflects your psycho-emotional response to the world, promoting internal states to be externalized and made into interactive forms of expression. Measuring the galvanic skin response (a marker of emotional arousal commonly used in lie detector tests), this device’s lights turn from blue to red as the wearer becomes aroused. Ask the wearer an evocative question and reveal his or her inner Truth.
