Signal Eyewear that reads the wearer's facial muscles continuously

Summary

This signal concerns glasses with sensors aimed at the wearer that track facial movements in real time. From those movements the system identifies the wearer's emotional state. Sitra cites the company Emteq Labs, dated October 2024. Emotion becomes a continuously logged stream of data produced by an everyday wearable. The device illustrates how sensing of inner states is spreading beyond clinics into consumer products, with privacy implications. Sitra places it among signals behind an imagined future article on commonplace neurotechnology, alongside brainwave headphones and earbuds.
