LIQUID KEYBOARD

Touch-typing works well on a physical keyboard. One can feel the keys and their location and has based on this a clear understanding on where all other keys are located without looking at them. Virtual keyboards do not allow touch-typing as firstly placing 10 fingers on the screen would activate keys accidentally and secondly one cannot feel the keys. Hence does not know where other keys located without look at them. For making touch-typing work on touch screens and surfaces the input system has to adapt to the touch screen conditions.Researchers from University of Technology,Sydney have come  up with a new idea through which typing on touch screens becomes much easier.They call it ‘LIQUIDKEYBOARD’.

Computer meant to be a large box containing a screen along with another big box namely CPU. This was the picture of COMPUTER a decade back. But with the revolution of laptops, computers became mobile and users too started carrying it where ever they want. And now it’s the generation of new tablet PC’s and smart phones as well up to some extent. But users didn’t loose interest in the desktops so far.

Information stored in laptops and iPads can be easily referred and used because we can carry them where ever we want. But what about desktops? Using pen drives would be a better answer but not a perfect one. We may want some information from our desktop when we are some where far from our house. And the second thing is the security of that information present in our desktop even if we keep passwords.

India released a Rs.1,500 ($30) laptop / Tablet PC for students and teachers in colleges and Universities. The device is currently not available for sale in the market as government has decided to launch it for students in 2011.

The price of this device (so called laptop) may even go below to Rs.1500 in future.

The laptops will be distributed in institutions by the HRD ministry.

In Brief

The year 2011 would be a technologically effective one as the once high priced laptops are getting low in their price. This laptop would bring the buyer, savings up to 50 percent.

According to reports, it is clear that the laptops would see a noticeable fall in their price which would be lesser by Rs.4800. National Mission on Education through Information and Communication Technology is supporting this project to enlighten the more and more students. There may be many methods to spread education but this one would prove to be an innovative style of imparting knowledge.

The education which would touch the lives of every student through this mode of technology would be possible easily. Thus, these laptops would be available at lesser cost. This style is meant to edify the large population to widen the horizon of knowledge among all in every aspect of life. This project has plans to sell the laptops at remarkably lesser rate.

As a part of India’s National Mission for Education, Information and Communication Technology (NMEICT) 504 universities and 25,000 colleges countrywide would be the recipients of these laptops.

Features:

This project was the outcome of experts coming together. The IT specialists came up with this idea at the Indian Institute of Science, Bangalore, IIT Kanpur, IIT Kharagpur, IIT Madras and IIT Bombay. These laptops are going to be given out by HRD ministry. It is being considered that these laptops would prove to be an asset for the students and will give them opportunity to excel in education.

By the end of 2011 there are gonna be no flying cars, no plots gonna be built in mars and no other sci-fi predictions. But there will be some major advancement in terms of smarter Internet devices and great leaps forward in the area of emerging technologies. This year already gave some fruits like Motorola Xoom, Android Honey comb and some cool stuff. And there are lots to come like iPad2, Play station phone and so on.

So let’s talk about some of those new products which are going to hit the market and leading to revolution.


YEAR OF TABLETS:

The tablets which started addict tech lovers are continuing their legacy in 2011 also. They had a good break through by the release of Motorola Xoom and Blackberry playbook. They may be jus a preview of what tablets are capable of. And by the end of the year there will be few surprises from Apple iPad2, dell, Acer and by many others. Google’s next generation tablet OS, Android Honeycomb, is also one to watch out for. Microsoft might reveal touch optimized Windows OS for tablets by mid 2011, but the most anticipated will be the Palm OS on HP Palm Pads.
The tablet war will be fierce with these new tablets, which might bring steep price drops into the tablet PC segment. At the same time, there will be huge improvements in tablet screens; probably more OLED adoption. Intel might also launch its Oak Trail processor tailored for tablet PCs, and without doubt there will be improvements in processor speed, RAM, storage space and cameras.


 Motorola xoom and blackberry playbook respectively

Broadband to speed up with 4G this year:

All of us want a faster connection and 2011 will bring more bandwidth to our mobile world with 4G. It is believed to be 10 times faster than current 3G networks and provides the speed equivalent (or more) than a standard landline wired connection. The launch of 4G around the world will vary greatly as telecoms seek to balance their 3G business with 4G, and as infrastructure is still being set up in many areas. Whether it’s 4G or not, mobile broadband will definitely speed up due to more manufacturers launching cheaper 3G devices and more people switching to 3G.

Motion control gaming:

65% of US households play video games and gaming will grow crazily in 2011, irrespective of the devices—smart phones, tablets, laptops, desktops and gaming consoles. More mobile devices will come equipped with gravity sensors and motion sensitive controls.
Nintendo’s Wii plus, Sony’s PlayStation Move and Microsoft’s Xbox 360 Kinect will become more widespread in 2011. In 2011 gaming consoles will start tracking your movements through cameras and follow voice commands through microphones (examples include the Xbox Controller and PlayStation Motion Controller).
Social gaming was on the rise in 2010 and it will soon get more popular on mobile phones and tablets. Smart phones and tablet PCs will primarily connect your social life in 2011, but with better graphics, more power, and more proficient augmented reality apps.

Google in the PC:

Google entered our lives in 1998 and might revisit the PC again with Google Chrome OS in 2011. Chrome OS is currently in its public beta testing phase on 12-inch Cr-48 notebooks, but might enter into commercial netbooks in mid 2011. Acer, Samsung and many big players are planning to launch netbooks powered by a lighter and faster Chrome OS. The much secured Chrome netbooks will run on 3G connectivity and could bring netbook prices down to USD 100 or lesser. Watch out Microsoft, Windows has a lot to fear from Chrome OS in 2011.

Near field communication:

  Near Field Communication or NFC technology will turn your phone into a digital wallet. Although Google Nexus S became the first smart phone to embrace NFC in 2010, NFC won’t be main stream until later in 2011. Google, Apple, LG and loads of other manufacturers have lined up to get their gadgets packed with NFC, a high-frequency wireless communications technology that enables exchange of data between devices at a distance of 10cm or less. So you have to flash your NFC enabled smart phone at a retail outlet instead of your credit card.

    Nokia has plans to bring NFC to all its smart phones. Google Android 2.3 already supports NFC and LG will roll out different NFC enabled gadgets this year as well. Apple is taking NFC seriously as well since 57% of iPhone users have shown interest in NFC; and the iPhone 5 is rumored to feature it.

Location based networking and Augmented Real

Twitter, Facebook, FourSquare, Gowalla, and Yelp, everyone wants to show your location and publish recommendation for friends, followers and even strangers. Nokia has inked a deal with China’ leading web portals Sina and Tencent to enable Chinese social users to tag locations in their updates. FourSquare currently has over 5 million users, 25000 new users daily and 2 million check-ins. Analysts expect that to quadruple in 2011. So it’s only going to get bigger.

More Surprises:

Apple surprised everyone last year with the iPad. What will be making us go wow in 2011?! The Sony PlayStation phone tops my list, but there are other contenders like the BlackBerry Presenter phone for showing PowerPoint presentations on projectors and monitors using Bluetooth connectivity. The Sony Vaio 3D, which will have a button to switch to 3D mode to play 3D games and watch 3D movies with glasses gets another Sony product near the top of my must play with list. Then there’s the MintPass dual screen dual boot tablet with Windows and Android, iPhone 5, PalmPads and Verizon LTE phones. HTC is experimenting with E-Ink displays and so is Amazon; there might be radical e-readers in the pipeline for 2011. Voice control will improve and more gadgets, from gaming consoles to televisions, will start recognizing your voice. Better Internet connection and improved FaceTime and Skype apps will improve video calls in 2011.
The Shanzhai will continue to gain inspiration from all of these advancements, continuously striving to offer devices at unique local price points, often improving on brand names designs in the process. But what’s potentially very compelling is the possibility of more Shanzhai companies developing into brands themselves. Since the market for smartphones, tablets and other devices is continuously expanding, so too is demand and the room for new players to make an impact.

Let’s watch out the making of history and let’s be a part of it…
