VarTech’s Optical Imaging Technology (VOI) for Large
Screen Displays
A
Revolution in Large Screen Touch Screens!
VarTech’s
optical imaging technology is both streamlined and
simple. VOI uses scanning optical cameras to sense
a 2-dimensional 'field' which, when interrupted by
a touch, uses sophisticated algorithms to return a
point co-ordinate.
Optical
imaging technology revolutionizes the way we interface
with computer technology. Since VOI uses no surface
coating it doesn't degrade the image quality in any
way. This also means surface scratches and contamination
will not affect the touchscreen performance. VOI provides
touch sensitivity to the entire screen, corners included,
and accuracy is guaranteed. VOI requires only one
calibration because there is no drift with optical
imaging technology.

FEATURES |
Plug-and-Play
VarTech’s new touch solutions do not require special
software drivers; they incorporate HID compliant USB plug-and-play
interfaces.
High
Clarity of Image
This technology uses optical components. No surface coatings
are used on the screens - hence images are kept crystal clear.
Light Touch
Any method can be used to touch the screen: a finger, a gloved
hand or any pointer. Only a light touch is required.
Whole
Screen Coverage
Optical imaging technology provides touch sensitivity over
the whole screen, including the corners. With over 400,000
touch points, accuracy is guaranteed.
Once-only
Calibration
Optical imaging technology touchscreens are calibrated just
once at commissioning time. The technology provides continuous
operation with no drift, no need to recalibrate.
Robust
Because optical imaging technology solutions don't employ
surface coatings, the customer-facing screen is not affected
by scratches or contamination. Also, the products can be easily
sealed for resistance to dirt, dust and moisture, making them
ideal for demanding public environments. VOI’s touchscreen
system is modular so that component parts can be replaced
in the event of failure or damage.
Additional
Functionality
Provides two-touch capability (reading two touch points at
one time), middle mouse-key scrolling and object size recognition.
Diagnostic utilities are also available.
