This is a digital device that can detect signs of charm and measure it in action, and it is the size of the iPhone.
This wearable device features an infrared sensor and a micro-microphone.
It tracks patterns of voice and body movement.
However, the social meter does not record voice.
It was created by Alex Pentland, a computer scientist at MIT's Human Dynamics Lab, and his team.
They found that people who used the expressions and gestures of the researchers related to charm were more likely to successfully reach new deals and negotiations. —
