Testing the calibration
1. Touch random points on the screen and check that the cursor is located
underneath your finger.
2. Drag your finger across the screen. Check that the cursor accurately follows
your movements.
3. Touch each corner and along each edge of the screen. Check that the cursor
reaches the full image area and that you can touch and activate all icons and
menus across the entire screen
4. If any part of the test fails, calibrate the touch screen again.
Customizing the touch response mode
The touch response mode defines how your touch emulates the functions of a
mouse. For example, you can define a touch to produce a button down (pressing a
mouse button) or button up (releasing the mouse button). Touch modes also define
how your touch produces a mouse click and double click. The SmartSet software
allows the following touch modes:
Desktop (default)
The system moves the cursor to the touch point, but does not generate a
button down as long as you continue to slide your finger around the
screen. When you pause and hold your finger steady, the system generates
a mouse button down. You can now slide your finger around the screen.
When you lift your finger, the system generates a button up.
Drawing
The system moves the cursor to the touch point and immediately generates
a button down. You can slide your finger around the screen with the button
held down. When you lift your finger, the system generates a button up.
Button
The system moves the cursor to the touch point and generates a button
down and up (a click). To drag, slide your finger around the screen (button
down). The system generates a button up after your lift your finger.
Click The system moves the cursor to the touch point and immediately generates
a button down and up (a click). Click mode does not generate a second
button down, does not support drag, and does not generate a mouse event
on finger liftoff.
Liftoff The system moves the cursor to the touch point, but does not generate a
mouse button down. You can slide your finger around the screen and your
movements are followed, but the system generates mouse move events
only. Lifting your finger off the screen generates a mouse button down. The
system then waits for a system-defined time delay, and generates a button
up. The system does not support drag in this mode, but liftoff mode is
useful for applications that require greater accuracy.
Touchdown
The system moves the cursor to the touch point, generates a button down,
waits for a system-defined time delay, and generates a button up. The
system does not generate a mouse event on finger lift-off. The system does
not support drag in this mode.
