Computer integrated manufacturing (CIM) systems with a significant level of human-computer interaction are often inefficient. This is particularly problematical for those users who have to interact with multiple subsystem interfaces. These difficulties can be traced back to the fact that representation of the user in existing manufacturing models and systems is inadequate. An approach that increases user representation to improve CIM interface design is proposed, in which stereotype-based user and task models are used to specify a common user interface for each individual system user. An overview of the architecture is followed by discussion of an application domain (statistical process control) in which a demonstrator based on the architecture has been tested.

Human factors engineering research into human-computer interaction (HCI) needs means to easily and objectively study HCI. The Instrumented Interface Construction (IICON) Evaluator, and its associated IICON Data Taps, provide such means. Any X Window system user interface built using development tools for which appropriate IICON Data Taps exist (e.g., IICON Data Taps/TAE+5.2) can be automatically instrumented. Instrumented interfaces can then be used by subjects, recording a complete transcript of user actions. Once an operator's session has been recorded, it can be replayed on-screen as needed for further observation and analysis. These capabilities are extremely helpful for developing cognitive task models (i.e., user models) for analytic purposes, or for construction of Intelligent Agents to be embedded in the operator's computer-based workstation. Furthermore, with a complete objective record of all operator actions, IICON Evaluator supports a wide variety of research investigations of HCI.
