Medical Instrumentation
Touch input allows the integration of
many functions into a single piece of
equipment, thus saving valuable lab or
surgery space. Plus, several touch
technologies can be completely sealed,
operated with gloved fingers, and are
unaffected by substances that may be present
on a surgical glove (such as ultrasound gel).
Mobile and Hand-Held Systems
As computers become commonplace in
applications such as warehouse inventory
control, route accounting for freight
movement, trade or commerce, and other
industries that require small and portable
equipment, the need for practical alternatives
to keyboards is increasing. Touch devices
are the ideal alternative in these applications
because they occupy no additional space and
many will tolerate the adverse conditions
unique to a mobile device, such as being left
in a hot cab of a truck, dropped on a
warehouse floor, or splashed with beverages
and other corrosive substances. Touch input
devices open new opportunities for mobile
applications as well. Whereas a keyboard is
obviously a dangerous and unpractical
device to use for driver controls in an
automobile or other vehicle, illuminated
graphical user interfaces can be safely
operated while driving, as well as at night or
in the dark.
Process Control
Traditionally, the operator interface for
process control systems consisted of banks
of discrete controls, switches and indicators.
Touch technology allows you to replace such
an interface with a flexible, reconfigurable
control panel that displays only the controls
and indicators that are relevant to a specific
process.
Unlike other input devices, some of the
more rugged touch technologies are not
degraded by a harsh environment. They
perform consistently under even the most
severe conditions, unaffected by
environmental factors such as vibration or
temperature extremes - conditions often
found in the process control environment.
Some touch technologies can be sealed,
making them impervious to dirt, water,
airborne particulates and other contaminants.
