Google Glass is a type of wearable technology that resembles a pair of eyeglasses. It features a small display that projects information in the user's field of vision, allowing them to access apps, take photos, and receive notifications hands-free. The device is controlled through voice commands and touchpad gestures on the side of the frame. Initially released in 2013, Google Glass was aimed at developers and early adopters. While it generated significant interest, it faced challenges related to privacy concerns and limited functionality. Over time, it has evolved into a tool for specific industries, such as healthcare and manufacturing, rather than mainstream consumer use.
