Introduction 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. It includes voice-controlled Android device that resembles a pair of eyeglasses and displays information directly in the user's field of vision. It offers an augmented reality experience by using visual, audio and location-based inputs to provide relevant information.

OHMD and AR Optical Head-Mounted Display (OHMD) An OHMD is a wearable display that has the capability of reflecting projected images as well as allowing the user to see through it. Augmented Reality(AR) Augmented reality (AR) is a live, copy, view of a physical, real-world environment whose elements are augmented (or supplemented) by computer-generated sensory input such as sound, video, graphics or GPS data. E.g. Nokia City Lens

Development Glass is being developed by Google X, which has worked on other futuristic technologies such as driverless cars.The project was announced on Google+ by Project Glass lead Babak Parviz. Around August 2011, a Glass prototype weighed 8 pounds (3,600 g). Glass was initially projected to be available to the public for "around the cost of current smartphones" by the end of The Explorer Edition is available to testers and Google I/O developers in the United States for $1,500, starting in April The product began testing in April In May 2012, Glass was demonstrated in the first test video shot with the eyewear, demonstrating the 720p HD first-person video recording capabilities of the device. The new models were to be available to testers before the end of In October 2013, speculation emerged that Glass will be marketed in stores located on floating barges that will be towed from city to city.

Glass Explorer program It is an early adopter program available for developers and consumers to test Google Glass, and gauge how people will want to use it. Entry into the Explorer program was made available to the general public on February 20, 2013, and ended on February 27, Features:  Wi-Fi  can tether via Bluetooth to share data connection  does not have built-in GPS or SMS messaging  can access these services through Bluetooth connection to Android devices.  supports Bluetooth headset profiles for use in making & receiving voice calls

Camera-Google Glass has the ability to take photos and record 720p HD video. While video is recording, the screen stays on. Display- Liquid Crystal on Silicon (LCoS), field-sequential color, LED illuminated display.Liquid Crystal on Silicon

Software Applications Free applications built by third-party developers, Google Now, Google Maps, Google+, and Gmail Translation app Word Lens, cooking app AllTheCooks, exercise app Strava. MyGlass- a companion Android and iOS app. Voice activation To activate Glass, wearers tilt their heads 30° upward (which can be altered for preference) 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"

How it works ?

Challenges The biggest challenge for Google will now be to make the Google Glass also usable for people with normal glasses (to compensate for a low vision). In this case the Google Glass has to be placed ahead of normal glasses - which doesn't look and feel well or like a glass. Google has to manufacture individual customized prisms, but this would be considerably more expensive than the standard production. Huge burden on internet infrastructure and force companies to increase capacity. It could also spark an increase in the cost of data plans.

Privacy concerns & Safety considerations Privacy concerns Intrusion of privacy, and the etiquette ethics of using the device in public and recording people without their permission. potential privacy-violating capabilities Safety considerations Careless driving Discourage workers to wear hearing protection in loud work environments

Healthcare applications Several proof of concepts for Google Glass have been proposed in healthcare: Google Glass could assist a liver biopsy and fistulaplasty. It has the potential to improve patient safety, operator comfort, and procedure efficiency in the field of interventional radiology. Indian Orthopedic Surgeon Selene G. Parekh conducted the foot and ankle surgery using Google Glass in Jaipur, which was broadcast live on Google website via the internet. Google Glass allows looking at an X-Ray or MRI without taking the eye off of the patient, and allows a doctor to communicate with a patient's family or friends during a procedure.

Advantages Glass is sleek, light and easily wearable and you won’t require keeping it on and off your pockets, like mobile phones. No Bluetooth or camera needed when Glass is on, it’ll do all for you. Glass will provide you detailed information and satisfactory results on your queries. Make phone calls, sms, s though Google Glass, no smartphone required. Keep your calendar events, information, contacts updated on Glass. Easier navigation and maps will be provided through Glass. Glass will make you look hi-tech and updated on technology and create an impressive impact on people.

Disadvantages No indication while clicking pictures (like pointing the camera) which almost sounds like a hidden camera trying to capture a non-ready subject. Chances are there to drop yourself down in the road while reading a text or since you can’t get your eyes off it. No public privacy concern so the worry of leaking out information still remains. Competition is on pace. The future might bring a contact lens version of Glass after which Google Glass is supposed to sink.

Research The quality of pictures and video are usable for healthcare education, reference, and remote consultation. The camera needs to be tilted to different angle for most of the operative procedures. Tele-consultation is possible—depending on the available bandwidth—during operative procedures. A stabilizer should be added to the video function to prevent choppy transmission when a surgeon looks to screens or colleagues. Battery life can be easily extended with the use of an external battery. Controlling the device and/or programs from another device is needed for some features because of sterile environment. Text-to-speech ("Take a Note" to Evernote) exhibited a correction rate of 60 percent, without the addition of a medical thesaurus. A protocol or checklist displayed on the screen of Glass can be helpful during procedures.

Conclusion Google Glass is a lightweight hands free device that should be worn as eye glasses. It is the next face changing challenge to technology. Unlike smartphones or tablets you don’t require putting it on and off your pocket all the time. Your eyes and voice is enough to operate it all the way.
