VANCOUVER, British Columbia, Canada – Amid news that Nintendo’s new handheld 3DS could be unsafe
for children under 6, photonics companies ramped up efforts toward protection standards
for three-dimensional viewing equipment and systems.
The gaming company announced in December that experts say the
eyes of children under 6 are still growing and developing, and that this development
could be hampered if the eyes are exposed to 3-D movies, television and games; the
problem appears to lie in the fact that 3-D systems deliver different images to
the right and left eyes. Nintendo encourages parents of young children to switch
to the 2-D option when their kids are in the room.
Amid concerns about the safety of new 3-D display systems, companies are developing new
technologies and calling for eye protection standards.
In addition, specialists have reported that people of any age
can feel uncomfortable or dizzy for about 30 minutes after viewing a film using
3-D glasses because of muscle weakness in the eye and decreased color response.
Zecotek Photonics Inc., which develops technologies for medical,
scientific and industrial uses, first called for safety standards to govern 3-D
systems in March 2010 and renewed that call after Nintendo made its announcement.
“We are calling those in the 3-D industry to develop standards
and guidance for 3-D systems which will be used by the consumer, particularly children,
for long viewing periods,” said Dr. A.F. Zerrouk, chairman, president and
CEO of Zecotek Photonics Inc., in a statement.
Zecotek, it turns out, has a 3-D system of its own, which it says
is easier on the eyes. “We have developed a 3-D auto-stereoscopic display
which does not require viewers to wear glasses, and because the 3-D effect is produced
using the widest possible number of views, it provides a much more natural viewing
experience than those systems requiring glasses,” Zerrouk said. “The
Zecotek 3-D display system has an effective viewing angle of up to 50° with
90 concurrent perspectives, allowing for multiple views at the same time.
“Due to the large number of perspectives, our 3-D system
has the important feature of constant motion parallax within the viewing angle.
Motion parallax eliminates the sense of imbalance and dizziness during normal observation
which can occur with polarized and shutter glasses used with other commercial systems
due to the limited number of views.”
Other companies are working on improving the safety and quality
of 3-D as well. Panasonic announced at the Consumer Electronics Show (CES) in January
that it has teamed up with the government of Japan to establish 3-D safety guidelines
for manufacturers of consumer electronics as well as for broadcasters and those
who produce 3-D content. And LG Display announced at CES that its next-generation
film patterned retarder technology will eliminate all the health, convenience and
cost issues associated with existing shutter glass 3-D technology.
