Stylus - A finger, digital pen, or any device
used to activate the touch system.
Touch Coordinates - The positions on the x-axis
and the y-axis where a touch is detected.
Touch Event - A response that is programmed
to occur when a touch target is touched,
such as activating a new display screen
or menu. In GUI applications, touch
events are usually mapped to mouse
button click events.
Touch Target - An icon, menu selection, touch
button, or other graphic representation
on the display that triggers an action
event when touched, such as changing
display screens or menus.
Transmissivity - The clarity of the image,
measured in percentage of light that is
allowed to pass through the touch
system. In overlay-based touch
systems, clarity is reduced relative to the
thickness of the overlay. Touch systems
that do not use overlay-based
technology have 100% transmissivity.
Z-axis - The capability to measure pressure
against the touch sensor, in addition to x
and y coordinates. Specific pressure
thresholds can be set to emulate mouse
button clicks and activate different
touch events.
