MtSensor Plug-in

The MtSensor plug-in manages global telestration and plug-in settings. The MtSensor plug-in is the scene plug-in that must be available for any MultiTouch feature to work. It is automatically added to the Scene if any of the Container or Geometry plug-ins that require it are inserted in the Scene. It can also be dragged from the Server Panel under Built Ins > SP > MultiTouchComp, to the plug-in tab under Scene Settings.

The MtSensor plug-in also provides a screen-wide telestration facility. It can be controller through plug-in parameters and buttons that are available for scripting.

Note: This plug-in is located in: Built Ins -> Scene plug-ins -> MultiTouchComp

This page contains the following topics and procedures:

MtSensor Configuration


  • Active: Enables/disables telestration input from user.

  • Minimum Telestration Width: Assigns minimum brush width based on pressure applied to sensor.

  • Maximum Telestration Width: Assigns maximum brush width based on pressure applied to sensor.

  • Color: Assigns a color for subsequent telestration drawing.

  • Id: Provides additional context in the handler script, specify a string that identifies any notifications dispatched by this plug-in. This is often included as an argument for the event so a common script may handle events from a number of plug-ins.

  • Set Shared Memory: Enables shared memory to be updated for the plug-in notifications if set to On.

  • Shared Memory Prefix: Sets a ‘prefix name’ to be prepended to the shared memory variables maintained by the plug-ins notifications. For plug-ins that maintain multiple fields each field name has the prefix prepended to it followed by a dot, so as to mimic member access to an object. For example, if the prefix is Obj, the fields field1 and field2 would be identified with the strings Obj.field1 and Obj.field2. The shared memory field ‘Obj’ is also maintained and is simply an integer that is modified every time any of its subfields is updated.

  • Shared Memory Type: Selects the shared memory area to update. Can be either Global, Scene, or Distributed.

  • SetDataPool: Shows ‘you wish’ plug-in notifications to set a DataPool variable.

  • DataPoolVariable: Shows the name of the DataPool variable one wishes to have set.

  • Init: Clears current telestration and make Telestration active.

  • Clear: Clears the contents of the attached telestration.


The MtSensor plug-in does not generate any events for the scripting engine. The scene-wide telestration feature emits the same events that the MtTelestrator plug-in emits.
