      Synchronous user interface is a medium where all objects being
      shared on it can be viewed indifferently from the geographical
      location and its users can interact with each other in
      real-time. Designing such an interface for users working
      collaboratively requires to deal with a number of issues.
      Herein, our concerns lies on the design of control component of
      Human-Computer Interaction (HCI) and corresponding User
      Interface (UI) software that implements it. We make use of our
      approach to interactive system development based on the MPX -
      Mapping from PAN (Protagonist Action Notation) into Xchart
      (eXtended Statechart) - and illustrate it by presenting the case
      study of a collaborative application.
