Signal Wearable EDA and heart-rate-variability sensors are credited with up to 84% stress detection accuracy

Summary

NTT DATA points to clinically validated wearable sensors as evidence that emotion sensing is already usable today. These devices measure electrodermal activity, a skin conductance signal, together with heart rate variability. The report says they can detect stress with accuracy of up to 84 percent, citing a peer-reviewed study on wearable physiological sensors. It presents this capability as enabling applications in healthcare, wellbeing and mobility. The sensors form part of what the report calls today's emotional infrastructure, alongside emotion recognition and real-time sentiment analysis. The figure is an upper bound, so real-world performance may vary across settings and users.
