Google Glass is a wearable computer with an Optical Head-Mounted Display (OHMD) that is being developed by Google in the Project Glass research and development project. Google Glass displays information in a smartphone-like hands free format that responds to voice commands and touch. Google Glass is a prototype Explorer version. If we were to take apart a Glass, two things would likely to happen, we would discover the components that make the Glasses works and second we would regret for ripping those gadgets off. Fortunately you are provided with the theory.
There are few different ways to control Google Glass. One is by using the Captive touch pad along the right side of the Glasses the touch-pad responds to the capacitance which is essentially a weak electrostatic field generated across the screen. When your fingers contact with the panel, a controller chip detects the resulting changes in electric capacitance and registers it as a touch. Swiping/moving your fingers horizontally helps you to navigate menus on the device. Moving it downwards on the touch-pad makes you go back out of a choice or, if you are at the top-level menu puts the Glass in sleep mode.
The second way to use or to control Google-Glass is through Voice Commands. A microphone on the Glass picks up your voice and the microprocessor interprets the commands. You cannot just say anything and expect Google-Glass to respond—there is a list of commands that one can use and nearly all of the commands starts with, ”OK, Glass,” which alerts your Glasses that a command will soon follow. For an example, “Ok,Glass, take a video” will send a command to the microprocessor to record a video of whatever you will be looking at.
As of early 2014, the processor in the Explorer version of the Google-Glass is of Texas instrument. It is an Open Multimedia Applications Platform chip (OMAP). These chips belong to a larger classification of memory chips called system on chip. That means there are multiple components working together. In this case an ARM-based microprocessor, video processor and a memory interface. According to Texas Instruments specifications, this chip can play a video at 1080presolution and 30frames per second. The main circuit board also houses a SanDisk flash drive for memory – 16gigabytes’ worth of storage though only 12 gigabytes are only available for the user.
While you can use Google-Glass to take photos and videos without having it connect to outside world, to get the most from the product you will need to connect to the internet. The two ways to do that are over Bluetooth (connecting to any other device, say smartphones) or WI-Fi. A single chip inside Google-Glass provides support for either types of connection. Another chip, the Sir Fstar IV, is a global positioning system (GPS) microchip that allows Google-Glass to determine its location via satellite signals.
Google is considering partnership with sun-glass retailers like Ray-Ban or Warby Parker and may also open retail stores to allow customers to try on this device. Thad Sterner, an augmented reality expert is a technical head/manager on the project.
