The Touch Options settings are:
On tablets without a physical touch on/off switch, the Enable touch input checkbox enables touch capability.
Double-Tap Time adjusts how fast you must tap for a double-click. Test your setting by positioning the cursor over the Test area and tapping twice.
Pointer Speed adjusts the screen pointer. Choose Slow to move the screen cursor at a slower rate with more finger motion. Choose Fast to move the screen cursor quickly with less motion.
Scrolling Speed adjusts the scrolling speed of the Scroll touch gesture.
Pointer Acceleration adjusts the acceleration level of the screen pointer. Choose a Low setting for a slower response to your finger motion on the tablet. Choose a High setting for a quicker response.
Note: Touch speed and acceleration settings in Wacom Tablet Properties are independent of overall system settings. Changes you make to settings in Wacom Tablet Properties do not affect similar system settings. However, changes made to overall system settings may affect your pen tablet settings.
