As 3D TVs are set to launch this year, what could some of the effects be on the people using them
Sony readies 3D TVs for launch
Sony will launch 3D televisions in June, entering an increasingly crowded market that is betting the revolutionary TV will become the next hot product in the electronics industry.
The maker of Bravia flat TVs hopes 3D models to make up 10 per cent of more than 25 million LCD TVs it aims to sell in the next financial year.
Sony holds high hopes of a shift to 3D as it will likely give a boost to many of its business operations, which range from TVs, digital cameras, and Blu-ray DVD players to digital cinema projectors on the hardware side and from videogames and TV programmes to feature films on the software side.
Panasonic plans to launch its 3D TVs in the United States on March 10th and says it will cooperate with top US electronics retailer Best Buy in promoting them.
Last month Samsung Electronics, the world’s number one TV brand, launched 3D TV sales in South Korea and said it would launch them globally this month with the aim of selling at least 2 million 3D TVs this year.
Sony will begin selling 3D TVs in Japan on June 10th and plans to launch in the overseas market around the same time.
The electronics and entertainment conglomerate expects a model with a 46-inch screen to sell for 350,000 yen ($3,875) and a 40-inch model to sell for 290,000 yen. Each model comes with two pairs of 3D glasses.
“We at Sony will liberate 3D from the confines of movie theatres and make it something that people can enjoy at home,” Sony senior vice president Yoshihisa Ishida told a news conference.
The sci-fi blockbuster Avatar and other recent titles have sparked massive interest in 3D movies, and electronics makers are now rushing to get flat panel TVs with three-dimensional visual effects to the market.
The more than 25 million LCD TVs Sony aims to sell in the next financial year compared with its own forecast of 15 million it plans to sell in the financial year ending this month.

Your Brain Waves Change When You Watch TV - Low Alpha Waves Can Lead to “Mind Fog”
If you experience “mind fog” after watching television, you are not alone. Studies have shown that watching television induces low alpha waves in the human brain. Alpha waves are brainwaves between 8 to 12 HZ. and are commonly associated with relaxed meditative states as well as brain states associated with suggestibility.
While Alpha waves achieved through meditation are beneficial (they promote relaxation and insight), too much time spent in the low Alpha wave state caused by TV can cause unfocussed daydreaming and inability to concentrate. Researchers have said that watching television is similar to staring at a blank wall for several hours.
In an experiment in 1969, Herbert Krugman monitored a person through many trials and found that in less than one minute of television viewing, the person’s brainwaves switched from Beta waves– brainwaves associated with active, logical thought– to primarily Alpha waves. When the subject stopped watching television and began reading a magazine, the brainwaves reverted to Beta waves.
One thing this indicates is that most parts of the brain, parts responsible for logical thought, tune out during television viewing. The impact of television viewing on one person’s brain state is obviously not enough to conclude that the same consequences apply to everyone; however, research involving many others, completed in the years following Krugman’s experiment, has repeatedly shown that watching television produces brainwaves in the low Alpha range.
Advertisers have known about this for a long time and they know how to take advantage of this passive, suggestible, brain state of the TV viewer. There is no need for an advertiser to use subliminal messages. The brain is already in a receptive state,
ready to absorb suggestions, within just a few seconds of the television being turned on. All advertisers have to do is flash a brand across the screen, and then attempt to make the viewer associate the product with something positive.
Research Shows 3-D Movies, TV Can Cause Eye Strain, Headaches
Three dimensional movies, like Avatar, are wowing us with their visual display. The science fiction epic Avatar won best drama and top director for filmmaker James Cameron at this year’s Golden Globe awards. But a study at the University of California Berkeley found that 3-D movies can cause eye strain.
Normally, when we look at things nearby, our eyes converge. They do the opposite when we look at things in the distance. Martin Banks, a professor of optometry at Berkeley, says 3-D doesn’t allow our eyes to follow the rules because we’re focusing on things both far and near at the same time. That’s called “vergence accommodation conflict.”
“You have to concentrate your eyes to something near, but focus your eyes on something far,” said Banks. “So you have to break that normal coupling between avergence and accommodation.”
And it can lead to headaches and blurred vision.
“You’re taking that normal relationship which has been coupled in the brain for years and you’re changing it. And what we showed is that can cause fatigue,” he added.
Banks says younger viewers are more vulnerable.
