Tools
e Tools property page provides the following information and functions.
NOTE: Your touch screen is configured and calibrated at the factory. However, if you notice that
the calibration is not as precise as you would like, you can use the 4 Points Calibration and/or
the Linearization tool to provide a more accurate alignment of the touch screen.
• Graph of the Linearization Curve of the touch screen: For reference and
troubleshooting purposes. See its usage in the discussion of the Linearization
function.
• 4 Points Calibration: Calibration aligns the touch panel with the video screen. e
touch screen must be calibrated to allow for positional accuracy of the stylus or nger
touch inputs.
• Clear and Calibrate: Clears the calibration/linearization parameters and allows you to
perform the 4 points calibration again.
• Linearization (9 or 25 points linearization is set within the “Setting” tab): e
linearization function provides for more precise mapping of the stylus or nger touch
inputs. Aer linearization is completed, the linearity of the touch screen will be shown
in the Linearization Curve window.
• Draw Test: Used for accuracy and performance checking.
1 4 Points Calibration
e touch screen must be calibrated before it can work accurately. is function pops up a
new window to guide you through the 4 points calibration. You should follow the guide to
touch and hold the blinking X symbol in the calibration window until it does not blink to
make sure that the utility can gather enough data for computation. In addition, a time line
bar is shown in the bottom of the window to indicate time elapsed. If the touch screen is not
touched before the time line bar reaches the right end, the calibration task will be terminated
automatically.
2 Linearization
is function provides for more accurate touch screen positional alignment. e
linearization function pops up a new window to guide you through the 9 or 25 points
calibration. Conguring the function for 9 or 25 points calibration is accessed in the
“Setting” tab. You should follow the guide to touch and hold the blinking X symbol in the
calibration window until it does not blink to make sure that the utility can gather enough
data for computation. In addition, a time line bar is shown in the bottom of the window to
