MoodMetric
While “mood rings” have existed for years, MoodMetric hopes to do more than simply indicate how you’re feeling: it wants to help you manage those emotions, too. MoodMetric measures nervous system signals to provide insight into its wearer’s mental state. The ring connects to a smartphone app, which the company claims can display how intense a person’s emotions are in real time. What’s less clear, however, is why anybody would need a gadget to tell them what mood they’re in.
