Google Glass is a wearable computer with an optical head-mounted display (OHMD). It is being developed by Google in the Project Glass research and development project,with a mission of producing a mass-marketubiquitous computer. Google Glass displays information in a smartphone-like hands-free format, that can communicate with the Internet via natural language voice commands.
While the frames do not currently have lenses fitted to them, Google is considering partnerships with sunglass retailers such as Ray-Ban or Warby Parker, and may also open retail stores to allow customers to try on the device.The Explorer Edition cannot be used by people who wear prescription glasses, but Google has confirmed that Glass will eventually work with frames and lenses that match the wearer’s prescription. The glasses will be modular and therefore possibly attachable to normal prescription glasses.On 26 Jan 2014, Google announced that they were adding four prescription frame choices for about $225.00 U.S. It is necessary to remove a small screw in order to move the Google Glass from one frame to another.
Glass is being developed by Google X.It has worked on other technologies such as driverless cars. The project was announced on Google+ by Project Glass lead Babak Parviz, an electrical engineer who has also worked on putting displays into contact lenses.Steve Lee is a product manager and “geolocation specialist”; and Sebastian Thrun developed Udacity as well as worked on the autonomous car project. Google has patented the design of Project Glass. Thad Starner is an augmented reality expert. And he is a technical lead/manager on the project.
A touchpad is located on the side of Google Glass, allowing users to control the device by swiping through a timeline-like interface displayed on the screen.Sliding backward shows current events, such as weather, and sliding forward shows past events, such as phone calls, photos, circle updates, etc.
Google Glass has the ability to take photos and record 720p HD video. While video is recording, the screen stays on.
The Explorer version of Google Glass uses a Liquid Crystal on Silicon (LCoS), field-sequential color, LED illuminated display.
The display’s LED illumination is first P-polarized and then shines through the in-coupling polarizing beam splitter (PBS) to the LCoS panel. The panel reflects the light and alters it to S-polarization at active pixel sites. The in-coupling PBS then reflects the S-polarized areas of light at 45° through the out-coupling beam splitter to a collimating reflector at the other end. Finally, the out-coupling beam splitter reflects the collimated light another 45° and into the wearer’s eye.
For the developer Explorer units:
Google Glass applications are free applications built by third-party developers. Glass also uses many existing Google applications, such as Google Now, Google Maps,Google+, and Gmail.
On April 15, 2013, Google released the Mirror API, allowing developers to start making apps for Glass. In the terms of service, it is stated that developers may not put ads in their apps or charge fees. A Google representative told The Verge that this might change in the future.
Many developers and companies have built applications for Glass, including news apps, facial recognition, exercise, photo manipulation, translation, and sharing to social networks, such as Facebook and Twitter.
On May 16, 2013, Google announced the release of seven new apps. They included reminders from Evernote, fashion news from Elle, and news alerts from CNN.Following Google’s XE7 Glass Explorer Edition update in early July 2013, evidence of a “Glass Boutique”, a store that will allow synchronization to Glass of Glassware and APKs, was noted.
Version XE8 made a debut for Google Glass on August 12, 2013. It brings an integrated video player with playback controls, the ability to post an update to Path, and lets users save notes to Evernote. Several other minute improvements include volume controls, improved voice recognition, and several new Google Now cards.
On November 19, 2013, Google unveiled its Glass Development Kit, showcasing a translation app Word Lens, a cooking app AllTheCooks, and an exercise app Strava among others as successful examples.
Google offers a companion Android and iOS app called MyGlass, which allows you to configure and manage your device.
Other than the touchpad, Google Glass can be controlled using “voice actions”. To activate Glass, wearers tilt their heads 30° upward or tap the touchpad, and say “O.K., Glass.” Once Glass is activated, wearers can say an action, such as “Take a picture”, “Record a video”, “Hangout with [person/Google+ circle]”, “Google ‘What year was Wikipedia founded?'”, “Give me directions to the Eiffel Tower”, and “Send a message to John”. For search results that are read back to the user, the voice response is relayed using bone conduction through a transducer that sits beside the ear, thereby rendering the sound almost inaudible to other people.
