Amazon's new Halo wearable can track activity, health, and emotions
Amazon Halo is really pushing user trust to the limit. The device, which costs $99.99 and also requires a subscription fee of $3.99 a month for the advanced features, tracks heart rate, steps, and body composition. But it also tracks your emotions based on your tone of voice. To be clear, users have to opt into the feature, and it isn't always listening. Instead, it is an intermittent check on the wearer's emotional state that gets reported back to the user. Basically, it has the potential to become a giant pool of training data so Amazon's Alexa can gain some emotional intelligence.
