Hi, here is a summary of what we discussed off-line already:
By registering a mitk::InteractionEventObserver sub-class as a micro service you can get notified about interactions, e.g. by casting the InteractionEvent object to an InteractionPositionEvent you can retrieve the position in the render window. It might be a good idea to decouple the event observation from the mapper by introducing a datanode property which contains the relevant position and is read by the mapper. That property can be set by the interaction event observer and the component which is in charge of instantiating the mapper would register the event observer as well and couple them through the data node property.
