We offer Pre-Engineered
and Custom-made Kiosk enclosures
to withstand the most demanding public environments. We have a
variety of affordable models that can accommodate almost any peripheral
components to suit virtually any kiosk application.
We
have designed Modular Kiosks that can
be disassembled and packed neatly in a very small box, transported
to the site and reassembled.
Optionally
we can design an enclosure to meet your exact requirements.

The
current trends is more towards small cabinets and is rightly pointed
out by Mr. Derek Fretheim, president of CeroView
"I
think the biggest difference from yesteryear to today is that
the technology is going miniaturized, where the size of the enclosure
is smaller. Having a smaller form factor has had an impact for
end customers for sure. The old bulky units were unappealing compared
to the fluid designs of today."
Based
on this theme we have designed Kiosk Enclosures that are not-bulky,
but power-packed and still lean, slim, trim and thin. Enclosures
that are secure and can immediately grab the users' attention.
Enclosures and surroundings that can depict a theme or an Advertisement
Campaign.

SCREEN TECHNOLOGY
Introduction
There are five basic types of touch screen technology: resistive,
capacitive, infrared, surface acoustic wave (SAW) and strain gauge.
Resistive and capacitive are the most commonly implemented although
all the technologies are viable and suited to different applications.
Resistive
Technology Back
This technology uses two layers of conductive material to create
an X/Y grid (vertical lines on one surface, horizontal the other).
When pressure is applied to the flexible top layer (typically
Mylar), the grid surfaces come in contact and allow current to
flow. The presence of current in a vertical and horizontal line
gives the X/Y coordinates of the touch.
Resistive
4 wire Technology Back
4-Wire resistive touch screen is the preferred solution for low
cost applications. It consists of a conductive bottom layer (ITO
Glass or Film) and a conductive top layer (ITO Film). The two
layers are suspended by many very small spacer dots.When a certain
point is touched, the top layer contacts the bottom layer and
a voltage charged by the controller is applied to the bottom layer's
electrodes. The coordinate X axis of the touch point can be detected
by measuring the voltage value thru the top ITO layer and the
coordinate Y axis of the touch point can be detected in the same
way by changing voltage input to the top layer's electrodes.
Resistive
5 wire Technology Back
5-Wire resistive touch screen is the preferred solution for applications
requiring durability and reliability over time. Similar to the
4-Wire technology, 5-Wire touch screen also consists of a conductive
bottom layer (ITO Glass or ITO Film) and a conductive top layer
(ITO Film). The fundamental structure difference between the two
is: in the 5-wire technology, all the electrodes are placed on
the bottom layer and the top layer acts only as a voltage measuring
probe. Therefore, the touch screen works properly even with damages
or scratches on the top layer.
Resistive
8 wire Technology Back
8-Wire resistive touch screen is the preferred solution for applications
requiring accuracy and no re-calibration over time. It is designed
based on the 4-wire resistive technology with each edge providing
one more sensing line as a stable voltage gradient for the touch
screen controller. The functionality of additional 4 lines is
to obtain the actual voltage generated by the drive voltage, so
the touch screen controller can automatically correct the drift
issue resulted from the harsh environment exposure or long time
usage.
Capacitive
Technology Back
Capacitive Touch Screen is an all-glass touch screen with double
side transparent conductive coating. There is electrode pattern
printed along the edges distributes a low voltage field over the
conductive layer. When a finger touches the screen and draws a
minute amount of current to the point of contact creating a voltage
drop. The current flow from each corner is proportional to the
distance to the touch point. The X/Y location of the point of
contact is calculated by the controller and transmitted to the
computer.
Infrared
These touch screens are similar to resistive, infrared screens
project horizontal and vertical beams of infrared light over the
surface of the screen. When a finger or other object breaks those
beams, the X/Y coordinates are calculated. These screens can also
be used by workers with gloves and are relatively impervious to
damage. Dirt, flies and other objects, however, do offer the possibility
for registering stray touches or blocking the light emitting or
receiving apertures. Workers who "cruise" with their
fingers before touching the screen can also trigger a false response.
SAW Back
In Surface acoustic wave technology high frequency sound waves
are transmitted through vertical and horizontal axes on the screen.
When a finger touches the surface, it shortens the time for the
"echoes" to reach receivers, giving the location of
the touch. SAW technology can also register on the Z axis, determining
the amount of force exerted on the screen. Gloves are not a hindrance
to operation and these screens are relatively impervious to stray
touches. In addition, if an application requires measurement on
the Z axis, SAW is a good choice. A new variation, guided acoustical
wave (GAW), directs the signal through the panel itself, not over
its surface. This allows the screen to be completely sealed.
SAW and GAW provide the brightest images since there are no overlays
to diminish the image.
