Amazon has stated that its Amazon Rekognition system has the ability to determine if people are scared. This makes fear the eighth human emotion that Amazon Rekognition is able to differentiate. The other emotions that the system can recognize include happiness, sadness, anger, surprise, disgust, calmness as well as confusion. The company also indicates that its facial recognition system is able to determine a person's age range. The company states that the system can accurately obtain a range, "across most age groups."
Notably, Amazon has been selling the Rekognition system to law enforcement agencies. The system and its customer base have drawn controversy, however Amazon's shareholders have voted to continue the sale of its fear-detecting facial recognition system.
