  • Cognitive engineering of a new telephone Operator Workstation using COGNET
    International Journal of Industrial Ergonomics, 1998
    Co-Authors: Joan M. Ryder, Monica Z. Weiland, Michael A. Szczepkowski, Wayne Zachary
    Abstract:

    Abstract Many cognitive engineering methodologies for user-centered design involve modeling procedural knowledge; others deal with domain semantics or conceptual models. COGnitive NEwork of Tasks (COGNET) is a framework for modeling human cognition and decision-making which provides an integrated representation of the knowledge, behavioral actions, strategies and problem solving skills used in a domain or task situation, yielding a powerful cognitive engineering tool. A case study of the design of the user interface for a new telephone Operator Workstation is presented to illustrate the derivation of the design from the components of the COGNET model. The model does not directly convey any specific feature of the interface design, but rather a formal representation of what the user must do with the resulting interface. This information is then evolved through a set of transformations which systematically move toward design features, in a fully traceable manner. Relevance to industry With the increasing prevalence of technical systems in complex work domains, cognitive engineering is necessary in designing the user interface for those systems to promote efficient integration of person and machine. The cognitive engineering methodology presented here addresses that need.

  • Using a web-based query engine and immersive virtual reality to select and view 3D anthropometry in vehicle Operator Workstation design
    46th AIAA ASME ASCE AHS ASC Structures Structural Dynamics and Materials Conference, 2005
    Co-Authors: Andy Kckean, Vijay Kalivarapu, Judy M. Vance, Eliot Winer, Jerry Duncan
    Abstract:

    This paper presents the development and testing of a tool for designing vehicle Operator Workstations using 3D anthropometry. The tool consists of two major modules: 1) a webbased engine to query a large database of human anthropometry for selecting human Operators representative of a specified user population, and 2) an immersive Virtual Reality (VR) software application used to view the selected anthropometry in relation to vehicle CAD designs. This tool allows a designer to view and interact with fully immersive 3D representations of vehicle Operator enclosures and controls from typical CAD models along with digital human models selected from the anthropometry database. This environment allows visualization to aid in the trade-off decisions that come between ergonomic and functional (i.e. structural, electrical, etc.) design. The environment makes use of a webbased interface for the querying of a large anthropometric dataset with over 4500 participants. A designer is presented with a rich set of features to build, store, and manage queries using attributes such as height, weight, reach, gender, and occupation to locate pertinent subsets of subjects for a specific vehicle design. A list of subjects obtained from the query engine can then be sent to a VR environment for viewing with vehicle CAD data. This linkage makes the selecting and viewing of subjects seamless. A detailed description of the design problem being addressed, software development, and sample test cases are presented to demonstrate the intuitive nature and ease of use of the environment.

  • An Immersive Workstation Design Tool Using Three-Dimensional Anthropometric Data
    Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 2003
    Co-Authors: Melinda M. Cerney, Judy M. Vance, Jerry Duncan
    Abstract:

    With the recent completion of the Civilian American and European Surface Anthropometry Resource (CAESAR), a comprehensive set of three-dimensional anthropometric data has been made available to the design community. This paper presents the development of a virtual reality tool which makes use of three-dimensional CAESAR data in a fully-immersive, virtual reality (VR) environment. This advanced Operator Workstation design tool enables design decisions to be made in a three-dimensional setting, allowing accurate visualization of relationships among human landmark data and Workstation geometry. Methods for filtering and selecting data are presented. In addition, the utilization of landmark relationships specified by 3D data in an immersive, 3D design space are examined. The rationale, development, and implementation of this advanced Operator Workstation design tool are also presented.

  • IROS - An examination of the STRIPE vehicle teleoperation system
    Proceedings of the 1997 IEEE RSJ International Conference on Intelligent Robot and Systems. Innovative Robotics for Real-World Applications. IROS '97, 1997
    Co-Authors: Jennifer S. Kay, Charles E. Thorpe
    Abstract:

    This paper describes a series of quantitative studies of a user interface for robot vehicle teleoperation. Supervised telerobotics using incremental polyhedral Earth geometry (STRIPE) is a teleoperation system for a robot vehicle that allows a human Operator to accurately control the remote vehicle across very low bandwidth communication links, and communication links with large delays. In STRIPE, a single image from a camera mounted on the vehicle is transmitted to the Operator Workstation. The Operator uses a mouse to pick a series of "waypoints" in the image that define a path that the vehicle should follow. These 2D waypoints are then transmitted back to the vehicle, where they are used to compute the appropriate steering commands while the next image is being transmitted. STRIPE requires no advance knowledge of the terrain to be traversed. This paper describes a series of tests of the STRIPE system. Conditions tested include different graphical interfaces, bandwidths, lenses, and rates of image compression.

  • CHI 95 Conference Companion - STRIPE: remote driving using limited image data
    Conference companion on Human factors in computing systems - CHI '95, 1995
    Co-Authors: Jennifer S. Kay
    Abstract:

    Driving a vehicle, either directly or remotely, is an inherently visual task. When heavy fog limits visibility, we reduce our car's speed to a slow crawl, even along very familiar roads. In teleoperation systems, an Operator's view is limited to images provided by one or more cameras mounted on the remote vehicle. Traditional methods of vehicle teleoperation require that a real time stream of images is transmitted from the vehicle camera to the Operator control station, and the Operator steers the vehicle accordingly. For this type of teleoperation, the transmission link between the vehicle and Operator Workstation must be very high bandwidth (because of the high volume of images required) and very low latency (because delayed images can cause Operators to steer incorrectly). In many situations, such a high-bandwidth, low-latency communication link is unavailable or even technically impossible to provide. Supervised TeleRobotics using Incremental Polyhedral Earth geometry, or STRIPE, is a teleoperation system for a robot vehicle that allows a human Operator to accurately control the remote vehicle across very low bandwidth communication links, and communication links with large delays. In STRIPE, a single image from a camera mounted on the vehicle is transmitted to the Operator Workstation. The Operator uses a mouse to pick a series of 'waypoints' in the image that define a path that the vehicle should follow. These 2D waypoints are then transmitted back to the vehicle, where they are used to compute the appropriate steering commands while the next image is being transmitted. STRIPE requires no advance knowledge of the terrain to be traversed, and can be used by novice Operators with only minimal training. STRIPE is a unique combination of computer and human control. The computer must determine the 3D world path designated by the 2D waypoints and then accurately control the vehicle over rugged terrain. The human issues involve accurate path selection, and the prevention of disorientation, a common problem across all types of teleoperation systems. STRIPE is the only semi-autonomous teleoperation system that can accurately follow paths designated in monocular images on varying terrain. The thesis describes the STRIPE algorithm for tracking points using the incremental geometry model, insight into the design and redesign of the interface, an analysis of the effects of potential errors, details of the user studies, and hints on how to improve both the algorithm and interface for future designs.

    Abstract:

    This report was developed to support improved bus procurement by public transit agencies, focusing on the bus Operator Workstation component of a bus. The project was designed to assist transit agencies and bus manufacturers in integrating improved and emerging technologies into current procurement practices and improving bus Operator Workstation design across the transit industry. The final deliverables for the project include this report, supplemented by six tools. The report provides an overview of the structure and content of the research, defines the role of each key stakeholder in the procurement process, and presents two types of training needed to support a well-prepared procurement team that includes bus Operators trained in their ergonomic needs. The report also presents important computer-aided design (CAD) and human modeling simulation models, now integral to modern bus procurement. Six appendices present detailed research results that complement the research report. The report is supplemented by three organizational tools and three design guidance tools that can be used by transit agencies during bus procurement. The organizational tools support the improvement of the bus procurement process and training for participants. The design guidance tools support current bus design technology. In updating the bus Operator Workstation guidelines, the research team sought to align the new tools, such as the Bus Operator Workstation Feature Guideline and the three-dimensional (3-D) Bus Operator Workstation Engineering CAD Model, with processes and practices now common in the commercial bus and truck industry. To assist in the communication of bus Operator Workstation requirements with individuals who are not trained in expensive and difficult CAD software, a Bus Operator Workstation 3-D PDF Model also was created. The six organizational and design guidance tools can be accessed from the report webpage at www.trb.org by searching “TCRP Report 185”.
