Google glass

• Google Glass is a wearable computer withan optical head-mounted display (OHMD).

• Google Glass displays information ina smart phone-like hands-free format.

• It mainly concentrates on the social networking, navigation and communication.

• The video camera senses the environment and recognizes the objects and people around. The whole working of the Google glasses depends upon the user voice commands itself.

PROJECT GLASS

• Project Glass is a research and development program by Google to develop an augmented reality head-mounted display (HMD). It is part of the Google X Lab, which works on other futuristic technologies. The intended purpose of Project Glass products would be the hands-free displaying of information currently available to most smart phone users, and allowing for interaction with the Internet via natural language voice commands

TECHNOLOGIES USED 1)WEARABLE COMPUTING: Wearable computers, also known as body-borne

computers are miniature electronic devices that are worn by the bearer under, with or on top of clothing. These computers are especially useful for applications that require more complex computational support than just hardware coded logics.

2) VIRTUAL REALITY Virtual reality is a term that applies to computer-

simulated environments that can simulate physical presence in places in the real world, as well as in imaginary worlds. The simulated environment can be similar to the real world in order to create a life like experience

3)AUGMENTED REALITY Augmented reality is a live, direct or indirect, view of

a physical, real-world environment whose elements are augmented by generated sensory input such as sound, video, graphics or GPS data. It is related to a more general concept called mediated reality, in which a view of reality is modified (possibly even diminished rather than augmented) by a computer.

4) AMBIENT INTELLIGENCE Ambient Intelligence (AmI) refers to electronic

environments that are sensitive and responsive to the presence of people. Ambient intelligence is a vision on the future of consumer electronics, telecommunications and computing.

5) SMART CLOTHING Smart clothing is the next generation of apparel. It is

a combination of new fabric technology and digital technology, which means that the clothing is made with new signal-transfer fabric technology installed with digital devices.

6) EYE TAP TECHNOLOGY An Eye Tap is a device that is worn in front of the eye

that acts as a camera to record the scene available to the eye as well as a display to superimpose a computer-generated imagery on the original scene available to the eye. It has the ability to augment and mediate the reality the user perceives.

7) 4G TECHNOLOGY 4G is the fourth generation of cell phone mobile

communications standards. It is a successor of the third generation (3G) standards. A 4G system provides mobile ultra-broadband Internet access, for example to laptops with USB wireless modems, to smart phones, and to other mobile devices.

8) ANDROID OPERATING SYSTEM Android is a Linux-based operating system for

mobile devices such as smart phones and tablet computers, developed by Google in conjunction with the Open Handset Alliance

HARDWARETECHNICAL SPECIFICATIONS• Android 4.4 • 640×360 Himax HX7309 LCoS display • 5-megapixel camera, capable of 720p video recording• Wi-Fi 802.11b/g• Bluetooth• 16GB storage (12 GB available) • Texas Instruments OMAP 4430 SoC 1.2Ghz Dual(ARMv7) • 2GB RAM • 3 axis gyroscope • 3 axis accelerometer • 3 axis magnetometer (compass) • Bone conduction audio transducer

MAJOR PARTS1) VIDEO DISPLAY It features with the small video display that is used

to display the pop up hands free information.

2) CAMERA It also has the front facing video camera with which

photos and videos can be taken in a glimpse.

3) SPEAKER It also has the front facing video camera with which

photos and videos can be taken in a glimpse.

4) BUTTON It also has the front facing video camera with which

photos and videos can be taken in a glimpse.

5) MICROPHONE A microphone is also put in, that can take the voice

commands of the wearer of user. This microphone is also used for having telephonic communication.

WORKING AND INBUILT FEATURES• Google Glass is tightly packed with

chips, sensors and feedback devices

• There are a few different ways to control Google Glass. One is by usingthe capacitive touch pad along the right side of the glasses. The touchpadresponds to changes in capacitance, which is essentially a weak electrostatic field generated across the screen

• Another way to control Google Glass is through voice commands. A microphone on the glasses picks up your voice and the microprocessor interprets the commands

• The processor in the Explorer version of Google Glass is from Texas Instruments. It's an Open Multimedia Applications Platform chip (OMAP). These chips belongto a larger classification of microchips called systems on chip

• The main circuit board also houses a SanDisk flash drive for memory –16 gigabytes' worth of storage. A companycalled Micron Memory supplied the dynamic random access memory (DRAM) chip.

• The most eye-catching component is the prism-like screen. When turned off, it appears to be a clear prism. Viewed from the top, you can just make out a diagonal line that bisects the prism's width. This diagonal line is where the prism has an angled layer that acts as a reflective surface

• Also on board the glasses are a proximity sensor and an ambient light sensor. These sensors help the glasses figure out if they are being worn or removed. You can choose to have your Google Glass go into sleep mode automatically if you take them off and wake up again when you put them on. These sensors can also detect if you take an action such as winking, which opens up the option to send commands such as "take a picture" just by giving a big wink.

• One last sensor inside Google Glass is the InvenSense MPU-9150. This chip is an inertial sensor, which means it detects motion.

• The power is provided by a battery housed in a wide section of the stem. It fits behind your right ear. It's a lithium polymer battery with a capacity of 2.1 watt-hours

MAJOR FEATURES• PHOTOGRAPHY, VIDEO AND SHARING You just say a word and Google Glass will take a

picture or record a video. The photos and videos will be stored on the flash memory of the device, and can also be shared on social networking websites

• SEND MESSAGE AND GOOGLE SEARCH Google Glass will show you text messages you

receive and allow you to reply to them via voice commands. If you are in the habit of Googling things a lot, you simply need to ask a question and the device will pull the answer from the internet

• GOOGLE TRANSLATE AND GOOGLE MAPS Google Glass translate a phrase or sentence from

one language to another. The widely used Google Maps are integrated into Glass, so that users will be able to chart the course of their journey or look up locations or establishments via voice commands.

ADVANTAGES• Easy to wear and use.• Sensitive and responsive to the presence of

people.• Fast access of maps, documents, videos, chats

and much more.• A new trend for fashion lovers together being an

innovative technology.• A spectacle based computer to reside directly on

your eyes rather than in your pouch or pocket.• A useful technology for all kinds of

handicapped/disabled people

DISADVANTAGES

• Can be easily broken or damaged. Though Google wants these glasses to be as modest as achievable, they seem to be extremely breakable. Users will have a tough time taking care of it.

• These glasses show the retrieved data in front of users eyes so it will be a tough experience for them since they will focus on that data and will eventually miss the surroundings that may lead to accidents while driving.

CONCLUSION

• Google glasses are basically wearable computers that use the evolving familiar technologies that brings the sophistication and ease of communication and information

• It is as futuristic a gadget we’ve seen in recent times. It’s limited in scope right now, but the future, Google believes, is bright and the device itself is “incredibly compelling”
