China seems to be leading the digitization of its work force. This article provides a glimpse into the latest development.
Beijing Public Transport Holding Group claimed the electronic bracelets were necessary to protect public safety. The wristbands are reportedly able to monitor a wearer’s vital signs, such as heart rate and blood oxygen level, as well as their sleep stats and overall emotional state. Hackaday points out that the hardware is little more than a common smartwatch, with software inferring the emotional state from those vital signs, and questions whether a machine can reliably read something as subjective as emotion at all.
Why does the public safety suddenly need to be protected? Rampaging bus drivers would probably have made the news.
