Both IntelliTouch and iTouch are surface-wave touch technologies.
IntelliTouch is applied on a piece of clear glass that is then integrated
into an LCD; iTouch is applied directly on the CRT faceplate.
The controller develops a digital map of the glass using ultrasonic
waves in the surface. A bare or gloved finger absorbs a portion of
the waves travelling across the surface and the resulting change in
the received signal is analysed by the controller and digitised into
X and Y coordinates. A third coordinate–Elo’s unique Z-axis–senses
pressure by measuring how much signal is absorbed.
Elo’s capacitive technology consists of a uniform conductive coating
on a glass panel. During operation, electrodes around the panel’s
edge evenly distribute a low voltage across the conductive layer,
creating a uniform electric field. A touch draws current from each
corner. The controller measures the ratio of the current flow from
the corners and calculates the touch location.
How touch systems work
Elo surface wave
An outstanding player’s experience yields increased coin-drop.
In independent comparative tests, players simply preferred
Elo’s surface-wave touch technology.
Extremely fast, sensitive touch response
The most accurate touch, even for small targets like
internet hyperlinks
Drift-free performance, not affected by surrounding
metal or poor earths
Never an incorrect or averaged double-touch from
two players
Ultimate picture quality and light transmission, with no
metallic layers or coatings
Minimized reflections from overhead lights
Z-axis for pressure adds a new dimension to games
Only Elo offers clear glass IntelliTouch and iTouch “touch-on-tube”
surface-wave technology. And only Elo has
recently patented
true flat surface-wave technology
with the transducers on
the
back
of the glass.
Elo capacitive
Elo capacitive touchscreens provide a solution for customers
seeking an alternative to the currently available capacitive
options. The Elo-designed controller is drop-in compatible
with both industry standard protocols, and the touchscreens
feature Elo’s advanced Z-border, a patented linearization
electrode pattern. With the addition of capacitive touchscreens,
Elo is firmly positioned as the primary single-source solution
for all mainstream touch technologies.
