Google Glass is a device that allows its user to engage in an augmented reality via an optical head-mounted display that comes in the form of typical glasses. The device has three key features: a touchpad, a camera and a display. A person can use the touchpad to control the device and navigate through its interface. Additionally, he can use his voice to communicate with the device.Continue Reading
The touchpad is located on the side of the glasses, and it recognizes the user’s input by detecting the changes in capacitance. Whenever a person touches the panel, a chip detects the variation in electric capacitance and registers the input as a touch. A person can navigate through the menus by swiping his finger horizontally; doing so downward puts the device in sleep mode, if it’s at the top-level menu, or backs out of the current menu level.
Google Glass features a microphone that can pick up a person’s voice, which is then interpreted by a microprocessor. As of 2014, the number of voice commands is limited, while all of the existing ones need to be prefaced with “OK, Glass.”
Although Google Glass can function offline while allowing the user to snap pictures or record video, most of its utility is derived from applications that require the device to be online. The device can connect to the Internet in two ways: Bluetooth or Wi-Fi. Google Glass features a single chip that handles both types of connections. In addition, it has having another chip, SirFstarIV, that allows the device to utilize the Global Positioning System.Learn more about Television & Video
