Pros and Cons of Three Different Display Methods For Getting a 3D Image

Pros and Cons of Three Different Display Methods For Getting a 3D Image

The majority of the current crop of 3D LCD TVs show 3D images by displaying two slightly different pictures on screen one after the other. Each eye gets to see the correct image by way of glasses that rapidly block and unblock the image so each eye only gets to see one image at a time. The world has depth because each of our eyes see it from a slightly different perspective. When the two slightly different images are shown in this way the brain is fooled into seeing an image with some depth to it.

The inherent problem with this technology is that first off you need expensive glasses and second you need a TV with a high refresh or scan rate. If you have a TV that is more than 4 or 5 years it is most likely not 3D capable. Once you have the TV you then need to get glasses compatible for your model. Unfortunately most families have at least 3 members. With my family I need to buy 6 pairs. Basically I'm investing almost the same amount of money spent on the TV on the shutter glasses just so we can all watch movies at the same time.

Luckily technology never stays still and we are already seeing new TVs available which can possibly eliminate the extra expense of glasses. New technology always costs more but TVs are becoming available that use polarized light to display the images. This is the same technique used in the movie theaters but on a smaller scale. The two pictures are projected onto the screen with polarized light. When the correct glasses are worn each eye only gets to see one picture each, both taken from a slightly different perspective. Refresh and scan rates are not as crucial as both images are shown at the same time.

For mostly solo viewing you can purchase LCD screens for 3D viewing without glasses. Through clever and secret use of technology the LCD screen is capable of displaying the two different images in such a way that each eye only sees its correspondingly correct image and all without glasses. Due to the nature of the way this works it currently cannot be done for a large audience or a widely dispersed one as in a movie theater. Each viewer has to be in the correct spot in order for each eye to get its correct image. If the viewer is outside of this sweet spot then they will not get the 3D effect.

Consequently it may be a while before we see this glasses free 3D technology in large TVs and projectors but it is available in the new Nintendo <a href="http://www.3dsgamesystem.com/">3DS game system</a>. As there is usually an audience of one with a personal gaming system then this technology is an excellent way to bring 3D gaming to the masses.

Samsung S3 'most popular phone of the year'

Samsung’s new Galaxy S3 phone is the fastest-selling pre-order phone of the year, Carphone Warehouse has revealed.

Although the retailer said Samsung would not allow it to release specific numbers at this point, it confirmed that "thousands" of customers have preordered the new flagship Google Android device.

More than 800 Carphone shops will stock the phone at launch, which will go on sale at 7.00pm and May 29 to those who have pre-ordered it. General sales will begin the following day.

Graham Stapleton, Chief Commercial Officer at Carphone Warehouse, claimed, "Pre-order demand for the new Galaxy S3 has surpassed expectations since the handset was first unveiled two weeks ago. The first 24 hours alone saw thousands placing their pre-order at Carphone Warehouse."

The news will come as a further boost to Android's operating system, which already accounts for more than half the world's smartphones. Earlier this week it was reported that 9 million S3s had been pre-ordered by more than 100 carriers.

Korean Samsung is the biggest mobile phone company in the world, ahead of long-time number one Nokia, and also the biggest maker of smartphones ahead of Apple.

Apple's latest iPhone, the 4S, was preordered more than one million times in its first 24 hours of online availability to a global audience, but no further official figures or breakdowns were released.

Stapleton added, "The Galaxy S3 is without a doubt the fastest selling pre-order of 2012 so far. We're gearing up for an exceptionally busy launch day at the end of the month as the handset lands on shelves at our stores across the UK."

The Korea Economic Daily also claims that Samsung’s factory is producing five million S3 devices a month, and is already operating at full capacity.

The Galaxy S3, unveiled at an international launch held at London’s Earls Court arena, includes innovative new features such as eye tracking so that the screen stays on while a user is looking at it.

Samsung has already said that it will "substantially contribute" to its second-quarter earnings. In the UK it will be free with monthly tariffs from £28 per month. The manufacturer is hoping the device will replicate the success of its predecessor, the SII, which has sold a total of 20million units.

The S3 also features a 4.8” display, one of the largest on the market, and the ability to automatically initiate a call to a contact onscreen when the phone is held up to its user’s face. Samsung has also added voice control, similar to Apple’s ‘personal assistant’ Siri, and will offer 50GB of online storage via a partnership with Dropbox.com.

Samsung has also announced that the device will be the official phone of the London Olympics, and said that “a limited edition showcase device enabled with Visa’s mobile payment application, Visa payWave, will be available for Samsung and Visa sponsored athletes and trialists”.

Microsoft's smartphone share is now below 2 per cent globally, while LG and Sony's is also falling.

Windows 7 overtakes Vista and XP

According to the measurements of NetApplications, Windows 7 (perhaps the most complex software platform for mass consumption) has reached in only three months the market share reached by Vista in almost a year.

Windows 7 ended January with a usage rate of 7.5%, a level that its predecessor, Windows Vista  reached only after 11 months from its launch in January 2007.

In January also both Windows XP and Vista have lost market share in favor of Windows 7.

Windows XP has reached  66.3% market share, down 1.46%. Vista has lost 0.5 percent and reached 17.4% share. 

If the trend of the last three months doesn’t change, Windows 7 will overcome vista and will be ranked second in the top of the most popular operating systems in June.

Microsoft launches So.cl network

Software giant Microsoft has launched So.cl (pronounced "social"), a social 'network' that was tested by university students in 2011. According to Microsoft, So.cl is an experimental research project developed by the company's FUSE Labs focused on exploring the possibilities of social search for the purpose of learning.

The service per se doesn't look similar to Facebook or Twitter. According to its FAQ, "So.cl is not meant to replace existing full-featured search and social networking tools. It is an experimental research project using a minimal set of features which help combine search with the social network for the purpose of learning."

Adding another layer to social networking it requires users to login through either their Facebook or Windows Live account. So.cl uses Facebook authentication, and a user's name and profile picture from Facebook also appears in So.cl.

However, by default Microsoft does not post any content from So.cl into Facebook stream. If a user chooses, he or she can post content to Facebook using the 'share to Facebook' feature in So.cl.

As for how it works, So.cl search is powered by Bing. Microsoft uses the public Bing APIs to display search result data. As students work together, they often look for the same content, and discover new shared interests by sharing results. These results can be web pages, images, or videos found through Bing. So.cl experiments on this concept by letting users share links as they search.

Facebook may allow children to join

 Facebook may relax a ban on children under the age of 13 joining its site after finding that many kids, some with their parents' permission and help, were already using it. 


"There is reputable evidence that there are kids under 13 who are lying about their age to get on to Facebook," Sunday Times quoted Simon Milner, Facebook's head of policy in Britain as saying. 


"Some seem to be doing it with their parents' permission and help," Milner said. If the decision to lift the ban is implemented, a flood of new users are likely to sign up to the social network, which floated on the stock market last week for $105 billion last week. 


The number of people with profiles - currently estimated at 900 million active users - would probably hit the iconic one billion mark, meaning that more than one in seven people in the world would be an active user of the site. 


However, Milner said the decision to allow children to create profiles was still at a very early stage. Milner said he will launch a debate about the minimum age in Britain when he appears next month at Wellington college, Berkshire. 


"We have a strict under-13 rule because of legal issues in America," he said. 
"We apply the same rule all over the world. But a lot of parents are happy their kids are on it. We would like to hear from people what the answer might be." Supporters of the minimum age believe it helps shield children from cyberbullying and inappropriate contact with adults. 


Past surveys in the UK have suggested that one in three British children has been the victim of abuse on the internet. The poll, commissioned by charity Beatbullying in 2009, also revealed that girls are up to four times more likely to face online bullying than boys, Daily Mail reported. Some school bullies have even set up Facebook groups allowing dozens of people to band together to abuse classmates, it said. Facebook has responded to criticism in the past by adding a number of safety features to the site to attempt to combat online bullying.
