Touch Controllers Reference Guide72
Pen or Finger
Syntax: <SOH>PF<CR>
Description: Sets the operational mode of a TouchPen controller to accept both pen
and finger input. Pen or Finger mode is also called automatic mode.
In Pen or Finger mode, the controller gives higher priority to the pen.
If the controller detects both pen and finger touches at the same
time, pen contact has higher priority. The controller acknowledges
only the pen touches and sends pen coordinate data to the host
system.
If the controller detects only finger contact, it sends the finger
coordinate data to the host system.
If you are using your finger and the pen touches the screen, the pen
overrides the finger input. In this case, the controller automatically
sends a finger liftoff coordinate when the pen touches the screen.
If you are using the pen and you lift the pen from the screen, the
system does not recognize finger (or hand) touch until after a
specified time delay.
This delay prevents accidental screen touches from being
interpreted as input. For example, if you rest your hand on the
screen while using the pen, you can lift the pen up and put it back
again without your hand touch being acknowledged. You can use
the Set Parameter Block command to change the amount of time
the system waits before acknowledging finger contact.
If a finger or hand is on the screen when the pen lifts off, the
system ignores the finger or hand until you lift your finger (or
hand) off the screen and touch the screen again.
