Icdm: Integrated Cooperative Decision Making - In Practice, Leonard Myers, Jens G. Pohl

Collaborative Agent Design (CAD) Research Center

Multi-agent systems provide an attractive architecture for the implementation of complex systems. Much of the research is focussed on complete automation of the decision making process as a means of duplicating human abilities for working with new problems and environments. There as also a need for systems that employ the human as an agent and rely on human abilities for common sense and deep thought. The CAD Research Center at Cal Poly and CDM Technologies have significant experience in building systems of the latter type that assist human users in solving complex problems in planning, design and economics. This experience …

Cognitive Engineering For Intelligent Man-Machine Systems, Erika Rogers

Computer Science and Software Engineering

This paper discusses a methodology for cognitive engineering which provides a framework for the cognitive studies→intelligent system development→cognitive studies cycle. The methodology has been developed to address the problem of providing knowledge-based cooperative assistance in visual reasoning tasks, and is discussed in terms of its impact on three different application domains: diagnostic radiology, geographical information systems, and tele-assisted robot supervision.

Tele-Assistance For Semi-Autonomous Robots, Erika Rogers, Robin R. Murphy

Computer Science and Software Engineering

This paper describes current work on a cooperative tele-assistance system for semi-autonomous robots. This system combines a robot architecture for limited autonomous perceptual and motor control with a knowledge-based operator assistant which provides strategic selection and enhancement of relevant data. The design of the system is presented, together with a number of exception-handling scenarios that were constructed as a result of experiments wit.h act.ual sensor data collected from two mobile robots.

Visual Interaction: A Link Between Perception And Problem Solving, Erika Rogers, Ronald C. Arkin

Computer Science and Software Engineering

The approach taken in this research is to develop a cognitive model of how a human observer extracts information from a visual display and then uses this perceptual information in a decision-making task. Knowledge about this relationship provides information about the occurrence of perceptual events in the course of problem-solving activities, and suggests that perceptual assistance in the form of image enhancements is a useful supplement to the user’s own abilities. This knowledge is then to be embedded in an intelligent computerized assistant which is designed to facilitate and stimulate the human problem-solving process.

Visual Interaction In Diagnostic Radiology, Erika Rogers, Ronald C. Arkin, M. Baron

Computer Science and Software Engineering

The concept of Visual Interaction is introduced as the process which links perception and problem-solving such that problem-solving is affected by what is seen, and conversely, what is seen and perceived is affected by the current state of the problem-solving process. This paper describes the development of a cognitively-based model of the visual interaction process in diagnostic radiology, and shows how aspects of this model are being incorporated into the design and implementation of an intelligent computer-based radiological assistant. In order to achieve this, it is necessary to extract information about the nature and type of knowledge involved in this …

Visual Protocol Collection For The Enhancement Of The Radiological Diagnostic Process, Erika Rogers, Ronald C. Arkin, M. Baron, N. Ezquerra, E. Garcia

Computer Science and Software Engineering

This paper describes the Observation Phase of a research project that is designed to explore the nature of visual radiological diagnosis. It is concerned with the collection and analysis of visual protocol data in an effort to determine the salient image features that may impact on the different stages of the diagnostic process, both perceptual and cognitive. These features, once identified, will lead to the formulation of image enhancement hypotheses and the development of knowledge-based visualization techniques to assist the radiological diagnostic process.

Method For Automatic Level Matching In A Local Network, In Particular A Multicomputer Arrangement, Comprising A Bus System Having Lightwaves Guides, For The Purpose Of Collision Recognition, Hans Thinschmidt, Franz J. Kurfess

Computer Science and Software Engineering

A method is disclosed for automatic level matching in a local network, particularly for a multicomputer arrangement, comprising an optical bus system, for the purpose of collision recognition. Given a required level matching, the process is executed such that a fundamental phase is provided in which level matching devices respectively individually assigned to the computers are synchronized with one another. A first matching phase is provided in which all level matching devices simultaneously execute a process for setting a reference voltage to the lowest received level, whereby the sum of all attenuation components of the signal path at the receiving …

The Construction Of Two Prototype Multi-Storey Air-Supported Buildings, Jens G. Pohl, James Montero

Collaborative Agent Design (CAD) Research Center

To treat a multi-storey building as a large, inflatable container forces the architect to consider design and construction criteria foreign to the building industry at large. While satisfactory progress has been made in the development of theoretical solutions for problems dealing with the structural and planning implications of a hyperbaric building environment, the time has come to consider practical issues.

This paper discusses the design, construction and operation of two prototype, multi-storey, air-supported buildings. The first building was completed in November, 1972 at the School of Building, University of New South Wales, Australia, and the second building was completed in …
