      The process of software development of human-computer interfaces
      is complex and expensive.  Many tools to automate the interface
      code generation have been proposed. The majority of these tools
      defines the behaviour of a system in terms of states and use
      conventional state transition diagrams (STDs) in order to describe
      dialogue control aspects.  The statechart notation extends STDs to
      overcome some of their drawbacks.  This paper shows the results
      gained from experiences of the use of statecharts in the
      development of user interfaces. These experiences led to the
      identification of improvements and additional constructs which are
      needed in order to make them more adequate for this specific usage
      in the even broader domain of distributed environments.
