Touch Reporting Mode A method that determines the form used to send data from the
touch system to the host. In scan reporting, the touch system
reports a list of physical beams that are interrupted in each axis.
In coordinate reporting, the touch system reports x, y coordinate
values that identify the touch location.
touch reporting type A touch mode that determines when touch coordinates are
reported. Enter Point Mode reports only the coordinates at which
a finger or stylus enters the touch screen. Exit Point Mode reports
only the coordinates at which the stylus exits the touch screen.
Tracking Mode reports the coordinates of the entry of the touch
screen and all movement within the screen. Continuous Mode
generates reports at intervals from the time the screen is entered
until it is exited, even though the finger or stylus is unmoving.
Exit Point reporting can be added as a modifier to the four basic
reporting types.
touch screen A glass overlay containing a transducer and reflectors, placed
over the display surface. A transducer mounted on the edge of the
glass emits an acoustic wave. The wave travels along the reflector
array, is redirected across the overlay to the reflecting edge, and
returns to the array where it is reflected back to the transducer.
The first reflector will send a signal back first, then the second,
and so on.
Touch State Report A touch reporting type under SFP-II that reports touch
coordinates at intervals from the time a stylus enters the screen
until it exits, even if the stylus is unmoving.
touch system The collection of all the components that are necessary to detect a
touch and report it to the host. This collection usually consists of
the touch frame or screen, protective bezel, controller, and
software.
transducer The device that is mounted on the corner of the glass overlay of a
guided wave touch system and emits an acoustic wave.
Tracking Mode A touch reporting type under the SFP that reports the coordinates
of the initial touch on the touch screen, as well as all movement
within the screen. Add Exit Point can be added as a modifier.
virtual beam Imaginary beams that occupy the spaces between physical beam.
