Part 16
Touch Function
Mouse emulation
The touch panel in HT system works exactly like a standard PS/2
mouse within the (primary) screen display area when its driver is properly
installed. However, if the system is running under safe mode due to a previous
improper shutdown or for any other reason, most drivers are disabled in this
mode and the touch panel calibration may not coincide with the mouse pointer
or even completely out of work. It is recommended to
use an USB mouse or
USB keyboard in safe mode
.
All the below mentioned mouse emulation functions in the primary
display area can be manipulated through relevant software. The system can
give a beep when the touch panel is touched and can respond as if the left
button of a mouse is clicked at the point touched. If the point touched is
dragged across the screen surface, it can respond as if it is using the mouse
drag and drop feature. If the point is touched, released and touched within a
short time interval, it will simulate double-clicking left button of the mouse.
Emulating the click on right button of a real mouse is further illustrated in
paragraph below.
Touch terminal manager
Before using the PS/2 interface resistive type touch control panel, one
must be aware that if you connect any monitor to the VGA port of HT system
for extended secondary display application,
you can not apply any touch
control function for this secondary display
due to driver conflict concerns!
The operation range of a PS/2 mouse is also limited within the primary display
area.
A program named “Posiflex Touch Terminal Manager” is installed in
the preloaded Windows system for the user to maneuver versatile features of
the touch terminal with a PS/2 interface touch panel controller. This program
can also be obtained by download from the POSIFLEX web site. However, the
installation process of this driver for Win XP and Win 2003 Server requires
some careful attention to the notice messages.
With proper setup and selection on control items in “Posiflex Touch
Terminal Manager”, a drawing representing a 2-button mouse will appear on
the desktop. Touch the right button in this drawing. Any touch on the screen
after this action will result in a right button mouse click at the point touched.
After touching the left button in this drawing the screen touch will resume the
left button function. This program also controls the beep generated when the
touch panel is touched, the detail in right button click emulation, and also
provides touch panel re-calibration. In principal, the touch panel requires no
further calibration once properly set.
