3D TV warning book launched

2010-04-23 21:13

Tokyo - A group of Japanese businesses has released a handbook advising viewers on health and safety when watching three-dimensional televisions to counter symptoms such as dizziness, nausea, and eye fatigue.

"There are basic rules to know" when watching 3D images safely, the consortium - which includes Hitachi, Toshiba, Sharp, as well as government bodies - said in its guidebook.

Different perspectives offered by each eye's line of sight enables the brain to process depth perception and therefore see images in three dimensions.

Television sets showing 3D images exploit this process by showing a slightly different image to each eye through a filter system operated by special glasses, which alternately shutter each eye's line of sight.

Electronics companies are rushing to bring 3D televisions to market with competition in the sector intensifying ahead of the northern hemisphere summer.

Technical problems

Sharp plans to unveil 3D versions of its Aquos model in May, joining rivals Samsung Electronics and Sony Corp in a space the industry hopes will revive profits amid a re-evaluation of the liquid crystal display business.

The guide advises audiences to respect the viewing distance, generally three times the height of the screen, adding that viewers should refrain from watching if they feel they are unable to see 3D images after prolonged viewing.

"If even in that case and after having verified any technical problems, the viewer doesn't see any depth perception and that he sees superimposed images, then he should stop," the handbook says.

It also urges viewers to stop watching if they start feeling sick or tired, saying that "perception varies greatly among people for various reasons".

Parents also need to be informed of risks when infants are involved.

"It is desirable that adults judge whether 3D televisions are suitable for their children," the group said.

It also requests makers of 3D televisions to take various preventative measures against potentially harmful symptoms affecting unaware viewers, such as unsynchronised shutters on glasses.

    New TV technology has become scarey. Imagine now having a couple of cold ones or some hard tack when watching the rugby. What with the superimposed pictures. Then one can then view about 4 programs simultaneously.
    It would be advisable to have the hearache powders at hand.

    Hmmm, in other words they are well aware of the fact that they haven't quite got it right yet but to heck with that let's just beat the competition to the production line. Hell we can make a fortune. Hey, the next one will be better and we can offer that at twice the price. Can you imagine if the motor industry operated in the same manner. You buy a car and six months later you get a bunch of bolts in the mail with a letter advising you to install these as a wheel may come off. Would you buy a car from them again? Crazy that we put up with this stuff in the IT and technology sectors!

    Should maybe wait until they bring 3D TVs out. Wait where you wouldn't need glasses. I really don't want to sit in front of my TV, in my house, with glasses on.
