Requirements for user interaction support in future CACE environments

Based on a review of user interaction modes and the specific needs of the CACE domain the paper describes requirements for user interaction in future CACE environments. Taking another look at the design process in CACE key areas in need of more user interaction support are pointed out. Three concepts are described through examples, dynamic data access, parallel evaluation and active documentation. The features of existing tools are summarized. The problem of how easily or `naturally´ the novel concepts are integrated is stressed
