OLED is the future of TV sets,  At present it is LCD's  reign, though not for long. But in present  Only four companies, Samsung and LG have manufactured OLED  TV sets. In 2012, Sony and Panasonic had announced that they will jointly manufacture these.  

Science behind it:        

OLED screen  previously  were used in cellphone and digital camera, but their manufacturing cost kept them from being  produced as big TV screens . 

OLEDs are semiconductors made of layers of organic material. They create light in much the same way as a traditional LED does. Manufacturers make the screens by spraying organic films onto a substrate, typically glass or plastic, printing out patterns the way ink dots are printed on paper

Why it is Better?  (Here LG is used as example)

  
  An LCD TV needs a backlight, but an OLED’s pixels emit their own light. So turning them off makes them go completely black, with none of the afterglow you’d get from phosphor-based technologies—like cathode ray tubes or plasma displays  or even from an LED-backlit LCD, which can dim only regions of the screen, not individual pixels. Being able to create a really black, greatly improves picture quality

LG has announced that its first 55-inch OLED TV is just 4 millimeters thick and weigh 7.5 kilograms. A comparable 55-inch LCD TV from LG is nearly 4 centimeters thick and weighs about 22 kg. 

Prices:

 LG uses a technology known as WOLED (White OLED with colour filters), for which the average price of one display comes to $3,600 (around £2,250). Whereas Samsung uses a different technology, called RGB (Red, Green and Blue) OLED, for which the average cost of manufacturing one unit becomes $7,300 (approximately £4,550).

Neither technology is especially cheap, yet the difference in production cost is evident, Samsung’s curved OLED TV is available for just €7,999 in Germany, compared to €8,999 for LG’s.

Prices are insanely high, it could be better if prices made low, What do you say ?

OMG! where the technology is taking us, now it is finally in the hand of users to control your pc/tablets through eye gesture.

 Tobii PCEye Go is a peripheral eye tracker that enhances computer accessibility with the speed, power and accuracy of gaze interaction. The device replaces the standard mouse, allowing you to navigate and control a desktop or laptop computer using only your eyes.
                     

            Computer Access through Gaze Interaction

The PCEye Go runs on standard Windows computers and tablets, allowing you to work with any application that is normally controlled by a standard computer mouse or through touch. Surf the web, connect with friends online, play games, Skype, use environmental controls to turn on the lights or TV and even make spreadsheets and documents by using your eyes.

Users with limited motor skills due to ALS, spinal cord injuries or other impairments can benefit greatly with the Tobii PCEye Go. They can enjoy:
Relaxed, precise and faster computer access
The PCEye Go comes with the award winning Gaze Selection. Gaze Selection makes it possible to control your desktop, or any other application, through an intuitive two-step process that reduces the risk of unwanted clicks. With Gaze Selection you can enjoy:

More relaxed computer access – With the two-step process of Gaze Selection, clicks are made intentionally and navigation is more intuitive, creating the most relaxed and natural computing environment.

Ability to hit smaller targets – Gaze Selection incorporates a unique zoom functionality that gives a virtually pixel-precise control of where you point, click and drag, enabling full computer access.

Faster computer access – Unique only to Tobii Gaze Selection you efficiently access all of the functions of your computer with fewer mistakes and clicks, and at high speed.

Integrated keyboard – Use the built in keyboard to write texts or to enter a web address.

Portable computer access
Tobii PCEye Go, fits snuggly on your laptop or on a desktop computer screen. With the Tobii EyeMobile bracket you can also use the Tobii PCEye Go together with a standard, off-the-shelf, tablet that runs Windows 8 Pro.

The PCEye Go easily attaches and detaches from your desktop screen or laptop using a smart, seamless magnetic mounting bracket and USB connection. On the EyeMobile bracket, you simply slide the eye tracker into the tube and connect it to the tablet via the USB port.

The PCEye Go is lightweight and small enough to be easily transported and used with different computers and tablets and in different environments, for example at home, at work or in school.

Scalable computer access
All processing for the eye tracker is done on the device itself, avoiding additional workload for your computer or tablt. This also means that you do not need the latest, most expensive tablt, laptop or desktop in order to use gaze interaction as a computer access method.

If you do have high PC performance demands, like playing processor intense games or if you want to keep up with technology, the modular design of the PCEye is ideal. Simply upgrade your computer and continue using the same eye tracker via a single USB connection.

Technology change is a evident fact, and indeed a technological revolution is awaiting for us, in fact as we speak now, designers and engineers are busy in their labs creating and testing new mind boggling things. Among them i came up with haptics today.

HAPTICS

The origin of the word haptics is the Greek haptikos. Haptic feedback is commonly used in arcade games, especially racing video games. In 1976, Sega's motorbike game Moto-Cross, also known as Fonz, was the first game to use haptic feedback which caused the handlebars to vibrate during a collision with another vehicle. Tatsumi's TX-1 introduced force feedback to car driving games in 1983.

Haptics is not limited to gaming, its uses can be far reaching like mobiles, tabs, automobiles, medical etc, but to specify it with a practical example , this picture might be of great  help

if your touch screens came up with haptics technologies then your can literally feel the
surface of the image, Haptic sensations are created in consumer devices by actuators, or motors, which create a vibration.  Those vibrations are managed and controlled by embedded software, and integrated into device user interfaces and applications via the embedded control software APIs(Application programming interfaces).
Earlier versions of this technology was integrated into a joystick, which actually exerts a force to players hand as a feedback.

There are currently no commercially available  platforms that use this functionality, but the technology is in development by a number of firms. KDDI and Kyocera jointly announced in 2011 that they were collaborating on research. And, at the Future World Symposium electronics industry conference, 2012, HiWave's (haptics division now spun out to become Redux) CEO stated that the company was also working on pressure sensitive technology.

In June 2013 a fourth generation haptics demonstration platform, called Bulldog, was announced in the UK electronics publication Electronics Weekly. This took the force exerted by a finger into consideration when delivering the haptic feedback and gave three levels of feedback from a flat panel.

Today text to speech are very common in different platforms. In windows7 or xp the default voice is very primitive in nature, there are several text to speech software available in the market, with different voice modules , some can offer really innovative voices like josh offered by acapela, also most of the software support a vast array of languages for text to speech. But there is another player with little size of 10mb around, and free absolutely. stood fairly good, but it can'nt stood in comparison with premium voices from neospeech, nexup, or at&t etc.

i am showing the steps to activate this support:

step1: open any page on opera (my version is 11.60)

                           

                                   

step2:  select any portion of text, and then right click, then click speak in the list

step3:  after that a window will appear, asking you, that you want to download the module  or 

not , click yes

                                       

step4: once you have downloaded the module, you can use the text to speech any time, but its is better to keep a copy of the module.
                                                                for windows 7 users

                                        
goto the target folder as depicted in the picture's address bar.(goto the folder which you have named, as "Abhishek sen" in my case)


                                                               for windows xp user



                                          
goto the target folder as depicted in the picture's address bar(goto the folder which you have named, as "administrator" in my case)

Now you can save a copy of folder "voice", so if you install opera again in your system then just pate the copied folder to the target folder, you will find that your speak option is ready to be used.

Microsoft plans on spending $7.1 billion in cash on the Nokia’s Devices and Services division 

It’s finally official, Nokia is joining Microsoft — well at least part of it — with today’s announcement that Microsoft plans on spending $7.1 billion in cash on the Finnish firm’s Devices and Services division.

It had been long rumoured that the two companies had been in talks about a potential takeover by Microsoft, but speculation has been quiet as of late.
In the deal Microsoft will get a lot more than a dedicated phone hardware business, it will also license Nokia’s patent portfolio, receive 32,000 Nokia employees and gain former Microsoftie and Nokia CEO Stephen Elop.
Rumours have it that Elop is the top candidate for the person to replace Steve Ballmer when he steps down as CEO, although Microsoft hasn’t confirmed those rumours — refusing to comment on whether the Nokia acquisition had anything to do with poaching Elop.
One thing Microsoft won’t receive in the purchase will be the Nokia brand, which will be licensed for ten years for feature phones only, meaning the Lumia line of smartphones will have to drop the Nokia brand in the future.
Nokia and Microsoft have been close ever since Nokia announced plans to drop Symbianin favour of Windows Phone.
Since that deal Nokia has pumped out an impressive line of smartphones, including theNokia Lumia 925 and the Lumia 1020.
Steve Ballmer solidifying Microsoft’s position as devices & services
This deal is likely to be the last major decision of Microsoft’s current CEO Steve Ballmer, who plans on stepping down within the next 12 months — but he is refusing to go quietly.
Despite being a controversial CEO, Ballmer has completely changed Microsoft from an almost exclusive software company into a fully fledged devices and services company — with the purchase of Nokia solidifying Microsoft this change.
During his tenure as CEO, Ballmer has overseen many acquisitions, including the pricey$8.5 billion purchase of Skype in 2011.
Current state of Windows Phone
Microsoft and Nokia may become one, but it still has an upward battle to fight, with Windows Phone’s marketshare still just 3.7 percent worldwide in the second quarter of 2013.
The change in Nokia branding on its smartphone lineup may help Windows Phone’s efforts in the US, where Nokia has traditionally done poorly, but in Europe the company still has a strong brand presence.
Windows Phone has also done rather successfully in Europe thanks to Nokia, with market penetration in Europe at 8.2 percent, accounting for one in 10 smartphone sales in the UK, France and Germany according to Kantar Worldpanel.
Whether or not a Microsoft branded Lumia line can continue Nokia’s success, we’ll have to wait and see.
Nokia has been the catalyst for Windows Phone growth, with other OEMs accounting for just 13.1% of total Windows Phone sales according to AdDuplex.
Despite that, Microsoft has reassured other OEMs that it’s business as usual and that it remains committed to them — although OEMs weren’t best pleased when Microsoft said the same thing after announcing the Surface.
Microsoft’s future
Microsoft is clearly going the biggest change the company has ever seen, but whether Nokia’s ethos fits into that remains to be seen.
Whilst the Surface is beautifully designed and well built, next to a Nokia Lumia it’s rather out of place, with Microsoft using metallic angular design compared to Nokia’s curved polycarbonate.
Whether or not that means that the Lumia line will get a redesign is unknown, especially since Microsoft is gaining a plethora of new designers from Nokia.
Elop will also be put in charge of the Devices team at Microsoft, with Julie Larson-Green (who briefly led the Windows division after Steven Sinofsky stepped down) joining him at the top.
According to Nokia’s Chairman Risto Siilasmaa, the talks between Microsoft and Nokiahave been taking place since Mobile World Congress in February, with over 50 meetings having taken place.
It’s clear that this deal is a way of Microsoft replicating the success of Apple, who controls all aspects of software and hardware, and as of recently Google, who bought Motorola to give itself the ability to make hardware.
So far Microsoft appears to be the Google way of operating, continuing to license out the Windows Phone OS to other OEMs whilst still maintaining its own hardware division.
It will be interesting to see if Microsoft takes it to the extent that Google has though, with Google keeping Motorola at arms length since purchasing the company — with an ex employee revealing that Motorola has a harder time dealing with the Android team as a Google company, than it did before.
Nokia and Microsoft have already been close, which is clear from the phones that have come of that partnership.
A Nokia united under Microsoft may be able to squash criticisms from Nokia’s executive team, who feel that the app situation is in desperate need of being addressed andblaming Microsoft for the failure.
Whether this deal puts a stop to Nokia exclusive apps is up for debate still, although if Microsoft wants to maintain OEM partners, it can’t be seen as having favourites.
Nokia’s future
Nokia is a company that’s not going away, although its brand will work a lot more behind the scenes now — with just the feature phone lineup continuing to use the Nokia name.
It is highly unusual that Microsoft would only want to maintain the Nokia brand for feature phones, given its concentration on Windows Phone smartphones, but it is speculated that it could have been stipulated by Nokia’s board — giving for the spun off company to possibly still make a smartphone in the future, although it’s unlikely.
Nokia has maintained ownership of HERE Maps, although Microsoft continues to be permitted to use it — possibly spelling an end to Bing Maps.
It will also still control its patent portfolio, meaning that company will still be a big player in the market — despite not making hardware.
Nokia will also retain Nokia Solutions and Networks, which the company has only just acquired from its former partner Siemens. The division had been struggling as recently as 2011, the year it decided to refocus itself on building mobile broadband infrastructure.
Of course Nokia is going to be a much smaller company than it currently is, but the deal made sense for both Microsoft and Nokia — with Nokia getting rid of the division that cost it the most money, whilst Microsoft gaining a hardware presence in the phone business.
Nokia & Microsoft
Microsoft reportedly made just $10 from every Lumia that was sold, evidently a low number and one that Microsoft was desperate to increase.
This could strengthen Microsoft’s position if it makes all the right moves, but Microsoft had previously bought a phone manufacturer before, with the company being responsible for the fateful end of Danger — who was famously brought on to help buildthe Kin.
The Nokia brand may never be carried on a smartphone again, a daunting prospect given the company helped invent the smartphone.
One can only hope that the Nokia ringtone lives on. You can also stop hoping for an Android-based Lumia.

Hello friends, I hope all of you are fine, have seen my previous post about Digital camera, today I will post about Nintendo Wii, let us see how it works?

(Nintendo is the same company who created the world famous game Mario ) well, that was the fist game, that i played with video game

. 

Nintendo Wii

With the launch of Wii, Nintendo tried to cause a revolution in

the world of video-game consoles. Wii, the fifth generation of

Nintendo's video-game consoles and part of the seventh

generation of video gaming, is the successor to Nintendo's GameCube.

Wii has several features intended to help a wider audience play video

games and get closer to the world of virtual reality. Among them are

sophisticated wireless commands that transfer tactile effects, such as

blows and vibrations; infrared sensors that detect the position of the

player in a room and convey the information to the console; and

separate controls for each hand. Wii was a commercial success from

the moment of its launch in December 2006.

The Console

is the brain of Wii. Its slim

design (a mere 1.7 inches [4.4

cm] wide) plays the games that are

loaded on standard 4.7-inch (12-cm)

discs, accepting both single- and

double-layered discs.

System

has an IBM PowerPC processor,

ports for four controllers, two USB

ports, slots for memory expansion,

stereo sound, and support for playing

videos on panoramic 16:9 screens.

Connectivity

The console connects with the

Internet (it includes Wi-Fi wireless

connection), from which it can

receive updates 24 hours a day to

add or upgrade features.

The Movement Sensor

A player's movements are

detected by means of a flexible

silicon bar inside the Wiimote.

This bar moves within an electric

field generated by capacitors.

The player's movements cause

the bar to change the electric

field. The change is detected and

transmitted to the infrared

sensor, which translates it into

the movements of the virtual

character. 

Infrared sensor

detects the player's
position from up to a
distance of 32 feet
(10 m) or 16 feet (5
m) during use of the
pointer function
(used to indicate
points on the screen).

                                                                            The Wiimote

The Wiimote, the Wii's remote, differs from traditional game

consoles by looking more like a remote control than a videogame

controller. It was developed to be useable with just one hand.

 The Movement Sensor

 

A player's movements are

detected by means of a flexible

silicon bar inside the Wiimote.

This bar moves within an electric

field generated by capacitors.

The player's movements cause

the bar to change the electric

field. The change is detected and

transmitted to the infrared

sensor, which translates it into

the movements of the virtual

character.

Players

Up to four players

can participate

simultaneously in

the same game.

All of the sensors

use Bluetooth

wireless

technology

The “excessive enthusiasm” of some

early players caused worries about the

weakness of Wiimote straps, so

Nintendo decided to replace them with

safer ones and modified 3,200,000 units.
