It's stuff of science fiction movie but could become reality. Amazon is trying to develop a device that can detect our emotional states. You would wear it on your wrist and it can tell by your voice what you're feeling at the moment. Surprised that Alexa can't do that already?

After that it supposedly will give you tips on how you should interact with people based on how you're feeling. Now who really knows if this is legit or just another way for Amazon to sell you more stuff. It's just in the testing phase at the moment and no word on when it would be available to purchase. I'm guessing tinfoil-hat wearing folks will avoid this like the plague.
