Space Constraints
Many touch systems will be located in
areas where space is limited. Flat panels
require very little space, while CRTs tend to
be bulky. The amount of physical space
required for the touch system varies for the
different touch technologies. The type of
integration selected can also affect the
amount of space required to hold the system.
Invasive integrations tend to use less space
than noninvasive integrations.
Environmental Factors
Different touch systems are designed to
operate in a wide spectrum of environmental
conditions. When designing a touch-based
system, items to consider would be
sealability, durability, reliability, and
vulnerability to vandalism. Specific details
on these environmental considerations are
found in Sections 4 and 5.
Sealing
Depending on the environmental
conditions, the touch system may require
different degrees of sealability. Applications
that may require special consideration are
industrial/process control, medical
environments, point-of-sale, and outdoor
touch applications.
