Project Glass is an optical head-mounted display developed by Google that allows users to access information hands-free using natural language voice commands. Key features include notifications, directions, photos/videos, and sharing. It uses Android with a 640x360 display, camera, WiFi, Bluetooth, storage and runs on a 1GHz dual-core processor. Technologies employed include augmented reality, which overlays information on real objects, 4G for ultra-broadband internet, and wearable computing through eyeglasses. While convenient, concerns exist around distractions and potential health effects from prolonged use.
