Vibration and Shock
Vibration and shock affect each touch
technology differently, ranging from no
effect to severe equipment damage. This is
an important consideration if the application
is in an aircraft, train, ship, or other moving
device. Equipment used in industrial
applications can also be exposed to
significant vibration or shock.
Ambient Light
Ambient light is the level of visible and
invisible light in the area surrounding a
touch technology installation. Most
technologies are not affected by ambient
light. Infrared technologies can be adversely
affected depending on the manufacturer and
packaging of the infrared touch system.
Ambient light levels found in well-lit indoor
environments do not present any problems.
Temperature, Humidity and Altitude
The temperature, humidity and altitude
of the touch application environment have an
effect on the operation and durability of any
touch system. Plastics and electronics are
affected by temperature. Humidity enhances
the corrosion of circuitry. Altitude affects
the dissipation of the heat generated by
functioning electrical circuitry.
It is safe to say, however, that the impact
of these environmental factors on the touch
systems will be less (or at least no greater)
than their impact on the circuitry of the
display or flat panel to which the touch
system is integrated. Specific data regarding
the impact of these environmental factors
may be found in the technology comparison
charts.
