Google Glass

Google Glass was a head-mounted wearable computer developed by Google, featuring a small display positioned above the right eye.

Announced in 2012 and briefly available to consumers in 2014, it promised hands-free access to information, photography, and augmented reality.

The device became synonymous with privacy concerns—wearers were dubbed "glassholes"—and was discontinued for general consumers, though it found niche use in enterprise settings.
