    From ViewSonic Online User Guide Database

    This section will describe the general use and operation of the UPDD applications.

    UPDD Commander

    UPDD Commander can setup touch behavior definitions in all applications.

    Setup Touch Behaviors for All Applications

    The touch function options are based on the Mac trackpad. The Touch function relates to the processing of the touch events (tap, press, gestures, etc.) performed on the touch device. A common list of touch events and system actions are predefined and can be configured as suits.

    Setup Touch Behaviors for Specific Applications

    If the touch behaviors under All Applications are not enough for your use case, you can customize touch behaviors for specific applications. To activate, ensure UPDD Commander is open and go to: View > Show Hidden Application Groups.

    Touch Settings

    Function Description
    Interlock Indicates the touch priority given to the device.
    Low Pass Filter Smooths input and removes jitter from inputs subject to distortion.
    Interactive Touch Indicates that a press and hold will generate a right click. For MacOS, gestures need be set for right click processing if required.
    Assisted Double Click Time Assists double clicking by generating a second touch at the same location of the previous one. The second click needs to be within a certain time and distance (width) of the first click.
    Ignore Tip Switch When enabled the tip switch bit (AKA lift bit) is ignored. Normally used in conjunction with a non-zero value for liftoff_time_ms. Can also be useful if when dragging the device it occasionally generates unwanted pen up packets that you wish to ignore.
    Enabled Indicates touch is enabled. Can be used to disable touch for the device.

    Reset Settings

    Reset general/device settings back to the default settings. The option can be found under General in the left hand column.
