Google Glass

About a year ago Google announces its new project formally named as “Project Glass research and development project” and in a short period, it released the first version of Google Glasses which are offered to some selected people (developers and testers) for an introductory price of $1500.Hopefully these are available for public till the end of 2013 as authorities said.

What is Google Glass?

Google Glass is a wearable computer and it displays all data and information in a 25 inches high resolution screen right in front of your eyes, but not on a desktop, laptop tablet or any other device but in the air. It is in the shape of eye glasses having no lenses, but it has a tiny screen just above and to the right side of wearer’s right eye.
It is a camera, touchpad, display screen, battery and microphone built in a delicate eye frame which can create a display in your field of vision, and you can also take pictures, record video, search any word, phrase or location and also can translate on the go.
The device is controlled with a microphone and touchpad on the right arm of the frame, you can give commands by just talking to the device and it will then process your command and will display result in a display screen  in field of your vision.(interesting and adventurous)
Another interesting feature is sharing of data which may be pictures you are taking right now or any other thing, you can view your messages and answer them by just speaking. You can use Google hangout software, Google maps etc.
Google also offered MyGlass app. This sets your headset with an Android telephone. It can also translate any spoken word in your own or desired language. Third parties are also developing apps for Google Glasses, so hopefully we will see much advancement in this in the feature.
Some functions of Google Glasses are displayed in the pictures below.
IT Pakistan always give your updated infomation about new technology.

The Future of LED Lighting?

In August 2012, McKinsey & Company published Lighting the Way: Perspectives on the Global Lighting Market, a comprehensive analysis of current and future trends in the lighting industry. Below are excerpts from the report.


  • LED prices have eroded more aggressively, pulling forward the payback time of LED lighting. The inflection point for LED retrofit bulbs in the residential segment, for example, is now likely to be around 2015.

  • The value-based LED market share for 2011 is estimated at around 8 percent in North America. This is expected to grow to around 45 percent in 2016 and around 70 percent by 2020. Faster LED price erosion is supporting the accelerated uptake of LED.

  • The price of LEDs is tumbling even faster than anticipated, helping to further drive technology transition. The green revolution in lighting is also continuing apace, with other energy-efficient lighting technologies being acknowledged as a bridge towards full LED penetration.

  • The price premium on LED lighting products still remains high, and the initial purchase price represents a significant barrier to decision makers when considering an initial investment in general lighting applications. However, faster LED price erosion is pulling forward the payback time of LED lighting. Our analysis shows, for example, that faster price erosion in residential LED bulbs and office LED tubes is bringing forward the payback time in 2016 by one to two years. It is expected to be less than two years by then in the residential segment.

  • The largest application market in general lighting, residential, represented almost 40 percent of the total general lighting market in 2011. The LED market share in residential was estimated at around 7 percent in 2011 and is expected to be almost 50 percent in 2016, rising to more than 70 percent in 2020.
