Google Glass is a wearable computer with an optical head-mounted display that is being developed by Google. It functions as a smartphone that can be controlled via voice commands to access information like maps, emails, photos and more. The device has a camera, microphone, touchpad, Android operating system and can connect to the internet via WiFi and Bluetooth. While promising hands-free access to information, concerns exist around privacy and safety issues that come with an internet-connected device worn on a user's face.
