The 1970s mood ring gets a wearable tech makeover

A Finnish company called MoodMetric has now created a working mood ring that discreetly tracks how the wearer is feeling.

The old idea of a mood ring is one largely based in superstition — the rings really changed color based on temperature, no the wearer's disposition. However, technology has advanced far enough that a Finnish company called MoodMetric has now created a working mood ring that discreetly tracks how the wearer is feeling.

The Moodmetric ring fits onto the finger much like any other ring, but it's equipped with Bluetooth connectivity and skin conductance sensors that are able to detect a number of metrics that can indicate mood and emotions. By tracking the nervous system signals given off by the body, wearers can see when and where their stress levels peak throughout the day. The app then offers relaxation techniques to help them improve their mood. The ring itself can be charged via USB and the company is currently letting customers sign up to pre-order the device.

There's recently been a slew of devices that set out to track how users feel, rather than the usual fitness and activity monitoring — even down to the MindRider bike helmet that lets riders know when they get dangerously stressed on the road. Moodmetric is set apart from the competition thanks to its miniscule size. Are there other trackers that could take the form of an inconspicuous ring such as this?
