Capacitive Interactive Whiteboard--------The Dark Horse of interactive whiteboard - 2013-07-10 02:37:04
What is Capacitive Technology?
Capacitive technology has been known
for many years but did not become mainstream as a useful and robust user input
device until the mid-1990's where it began to become widely deployed as a ‘behind-the-glass’ discrete
touch button technology in high end cooktops and similar devices.
Capacitive technology,which allows an unlimited
number of unambiguous touches,produces higher resolution, is less sensitive to
EMI, and can be more efficient in its use of sensor space. Mutual capacitance
makes use of the fact that most conductive objects are able to hold a charge if
they are very close together. If another conductive object, such as a finger,
comes close to two conductive objects, the charge field (capacitance) between
the two objects changes because the humanbody capacitance “steals” some of the
charge.
In a mutual-capacitance touch screen, transparent
conductors are always patterned into spatially separated electrodes in two
layers,usually arranged as rows and columns.Because the intersections of each
row and column produce unique touch-coordinate pairs, the controller in a
mutual-capacitance touch screen measures each intersection individually. This
produces one of the major advantages of mutual-capacitance touch screens – the
ability to sense a touch at every electrode intersection on the screen.There is
no blind area.
Capacitive
Technology in interactive whiteboard industry
In interactive whiteboard
industry,infrared ,optical,electromagnetic,resistive technology is mainstream
technology.you hardly see capacitive interactive
whiteboard appeared in the market.Capacitive Interactive whiteboard as a dark
horse in interactive whiteboard market,little-known but potential.
Promethean has ever developed
capacitive interactive whiteboard.But it was not real capacitive iwb,which
combined electromagnetic with capacitive just allowed one users writing by
electromagnetic pen and others by finger touching.
In 2013,a creative and real interactive
whiteboard was born in INTECH laboratorybased on capacitive technology.We
called INTECH CP series capacitive interactive whiteboard,which
changes the interactive whiteboard history.You know,that is a bold attempt.
Why is it a bold attempt?Before CP
capacitive interactive whiteboard was developed,it is a dark horse that was
rarely known.Frankly speaking,it is even hard for us to collect engough files
to assess the future effect.BUT our feelings reminds us it will lead us to
success.
Why research capacitive interactive
whiteboard? INTECH R&D manager of Hardware in INTECH,Zheng said,”capacitive
technology is widely used in Phone,PC,touch screen and other devices,but in interactive
whiteboard industry,it is blank.We should make a new definition of capacitive
technology in interactive industry.It is a potential technology in iwb field.We
just try some different that change this industry”.
He also said,”compared to infrared technology,capactive
interactive whiteboard has more strengths,it is easier support for multi-touch
technology.Thanks to the special feature of capacitive,we can have more writing
area in iwb,there is no blind area”.
“Besides,Any objects on the board have no effect to
the writing operation.For example, when you are writing on the board by right
hands while you keep your another hand some distance from the board so that
keep from misoperation.It will not occured on CP.”
Although more manufacturers are intended
to have a research on capacitve touch screen.But the price of large size of
touch screen is expensive.We are committed to promote our capacitive
interactive whiteboard into every class in world.Capacitive IWB owned the
similar functions with touch screen,it is cheaper and easier for acceptance.
Capacitive Interactive Whiteboard & Media
When INTECH capacitve interactive
whiteboard appeared on the interactive whiteboard market firstly,the market is
crazy.It got more focus.The 64th Education Equipment Show in
Wuhan,China,CP wons a good reputation.”It is so interesting” ”I like the
multi-touch games” ”So magic”,some visitors praised.We also saw a lots of
friends operate whiteboard at the scene.
At the same time,there also have a lot of
exposure in a number of famous magazines and newspapers.”China projector Network””Electronic
Journal of Education””Huicong Network””Alibaba” both referred to capacitive
interactive whiteboard.
Capacitive interactive whiteboard has
already played well in the first war.We have reason to believe that capacitive
interactive will get more acceptances in the near future.
