PQ Labs - and TablerTV displays, which use PQ Labs overlays - can use either the TUIO or Windows HID Touch protocol to transmit touch events to a PC. In fact, it is technically possible for a PQ Labs or TablerTV display to send a message using both protocols at the same time. Intuiface requires that only one protocol be used.

An indication that both protocols are being used simultaneously is if a single finger touch-and-drag on an image results in an image resize rather than movement of that image around the screen. Other odd behavior can occur when manipulating assets or drawing on the screen.

Unless you need to use TUIO for a specific application, we advise you to turn off TUIO events and use Windows Native Touch only.

Using Windows Native Touch only

This is the recommended method. To configure it:

1. Run the PQ Labs MultiTouch Platform control panel.
2. Uncheck the Tuio Support and FlashTuio Support options.

Using TUIO protocol only

This may be useful if you are using 3rd party applications also requiring TUIO. To configure it:

1. Run the PQ Labs MultiTouch Platform control panel.
2. Uncheck the Windows Native Touch option.

NOTE: To use TUIO with Intuiface Composer or Player you must modify an Intuiface configuration file. The directions can be found here. You will need to un-comment the section dedicated to TUIO protocol by replacing the following section:

 <!-- use any TUIO device 
 <Device Id="0" Type="TUIO" Name="TUIO">
 <Param Name="Screen" Value="1" />
 <Param Name="Port" Value="3333" />
 </Device>
 -->

with

 <!-- use any TUIO device -->
 <Device Id="0" Type="TUIO" Name="TUIO">
 <Param Name="Screen" Value="1" />
 <Param Name="Port" Value="3333" />
 </Device>
