The work of this contract extends efforts on an intelligence testbed using the LOCATE Workspace Layout Tool. Work on plan recognition aspects of the testbed was extended in two ways: first, by creating an action, goal and plan hierarchy that permits LOCATE to match user actions to possible hierarchies, and second, by developing a generalisation of the goal and plan hierarchy through a decomposition into two-level, hierarchical recipes, which can be mixed and matched from various actions at the interface. Other work included comparing concepts used in the Al planning work in LOCATE to similar concepts in an Information Processing/Perceptual Control Theory (IP/PCT) model being developed at DCIEM; similarities and differences of the two approaches were identified and discussed. Ideas for generalising LOCATE's planning principles to development projects such as IPME and Safework (TRADEMARK), projects supported by DCIEM, were explored. Finally, the concept of building an interface analyser, to help automate customisation of intelligent aiding for other applications, was described and discussed.
