This is like a real life mood ring. The wristband will change colors to let your boss (or anyone) know what mood you're in
However, the wearable technology, called a Moodbeam, isn't here to monitor your physical health. Instead it allows your employer to track your emotional state.
The gadget, which links to a mobile phone app and web interface, has two buttons, one yellow and one blue. The idea is that you press the yellow one if you are feeling happy, and the blue one if you are sad.
