Human computer interaction can be specified successfully using the concept of information resources and the formal notation of graph grammars. In order to achieve a precise and continuous specification process between the requirements and design stages, however, a suitable strategy for refining abstract specifications into more concrete ones correctly and consistently is highly necessary. In this paper it will be proposed to apply graph rewrite rules at a meta level to abstract graph grammar specifications of human computer interaction in order to achieve correct and consistent refinements of the specifications wrt important requirements. A safety-critical system concerning the interaction between the pilot and the flight management system on the flight deck of an aircraft will be used as an example. A graph grammar specification of this interaction at an abstract level will be refined wrt mode visualization by a graph rewrite rule at a meta level.
