n Graphical User Interfaces
Graphical user interfaces support the use
of graphics, color, and sound to capture and
sustain a user’s interest. They are also intu-
itively easy to understand, allowing design-
ers to create systems that can be operated
easily by users with all different levels of
computer experience or literacy.
Graphical touch targets can be displayed
on much smaller displays than what is
needed to display written instructions.
Many new uses for small displays, such as
in computerized golf carts and shopping
carts, have emerged as a result.
n Easily Updated
Unlike fixed control panels, there are no
physical switches in a touch panel. Touch
targets are reconfigurable and can be easily
updated as required.
Most touch application screens, such as this CD Sampler,
are designed to be so intuitively easy to understand that no
instructions are necessary.
