Therefore, the mind reader often participates in the trial of the case, which is to analyze the suspect's micro-expression, thus drawing his true thoughts in his heart.

What will happen when this technology is combined with artificial intelligence AI?

A AI developed by NEURODATA, a technology company in Silicon Valley , recognizes 7 million faces, captures expressions at 1/24 second level, and can recognize more than 100 emotions through mechanical learning of algorithms, and has an accuracy rate of up to 90%. This means that AI may become a more efficient "mind reader" with orders of magnitude training. In the future, we may no longer have secrets.
