Smart glasses are wearable computing devices that incorporate optical head-mounted displays or augmented reality technology to project information in front of the user's eyes. They resemble traditional eyeglasses but are equipped with various advanced features such as a built-in camera, microphone, speakers or bone conduction technology, and sensors. These devices are designed to provide users with hands-free access to data and applications, enhancing their interaction with the digital world while maintaining an unobstructed view of the physical environment.
Smart glasses work by overlaying digital information onto the real world, often through transparent or semi-transparent displays embedded in the lenses. They can connect to smartphones or other devices via Bluetooth or Wi-Fi, allowing them to display notifications, navigation cues, or other data directly in the user's field of vision. Cameras and sensors gather data from the environment, which can be processed and analyzed using onboard chips or cloud-based services. Voice commands or touch-sensitive structures on the frames allow users to interact with the device, while some models even feature eye-tracking technology for more precise control. The integration of augmented reality (AR) enables applications in fields such as gaming, industrial maintenance, healthcare, and more, making smart glasses a versatile tool for both personal and professional use.
