Building high performance interactive computer systems requires                 the understanding of the cognitive processes by which users                     interact with such systems.  Unfortunately, capturing and                       interpreting this information is very difficult.  Current user                  protocol collection strategies are either obtrusive or capture                  data at too low a level (e.g. individual key strokes).  Previous                work has shown that a formal cognitive grammar can be a powerful                tool in capturing and analyzing users' interaction.  Parsing a                  low level interaction protocol with this grammar can reveal the                 user's higher level cognitive strategies.  Unfortunately, such                  cognitive grammars are complex and very difficult to develop.                   The goal of this research is to develop a set of tools an                       procedures for creating cognitive grammars.                                                                                                                     The research has three components.  The first, is to build a                    computerized environment for developing cognitive grammars.                     Second, is to include in that environment facilities to capture                 and analyze user protocols.  And finally the implications of this               work in the study of human-computer interaction will be examined.
