  • the digital library Integrated Task environment dlite
    ACM international conference on Digital libraries, 1997
    Co-Authors: Steve B Cousins, Eric A Bier, Andreas Paepcke, Terry Winograd, Ken Pier
    Abstract:

    We describe a case study in the design of a user interface to a digital library. Our design stems from a vision of a library as a channel to the vast array of digital information and doc ument services that are becoming available. Based on pub lished studies of library use and on scenarios, we developed a metaphor called workcenters, which are customized for users' Tasks. Due to our scenarios and to prior work in the CHI community, we chose a direct-manipulation realization of the metaphor. Our system, called DLITE, is designed to make it easy for users to interact with many different ser vices while focusing on a Task. Users have reacted favorably to the interface design in pilot testing, but a problem sur faced: we need a mechanism to teach new users about the metaphor and interface. We conclude by describing our approaches to this problem.

  • an animated direct manipulation interface to digital library services
    Human Factors in Computing Systems, 1997
    Co-Authors: Steve B Cousins, Ken Pier
    Abstract:

    The Digital Library Integrated Task Environment (DLITE) is a novel user interface concept for distributed document collections and services. It is an interaction prototype, not a polished graphical user interface, and is a front end to an evolving variety of distributed document services. DLITE is part of the Stanford University Digital Libraries research project. This videotape explains the principles of the DLITE design and shows the current implementation in action.

  • Ecological Interface Design for Petrochemical Process Control: An Empirical Assessment
    IEEE Transactions on Systems Man and Cybernetics - Part A: Systems and Humans, 2007
    Co-Authors: Greg A. Jamieson
    Abstract:

    Abnormal events in process plants cost the petrochemical industry billions of dollars annually. In part, these events are difficult to deal with because contemporary interfaces do not adequately inform operators about the state of the process. Laboratory simulator studies have shown that, in comparison with contemporary interfaces, ecological interfaces can lead to more effective monitoring and control behavior. However, ecological interfaces derived from work-domain analysis differ from more traditional human-centered interfaces that use a Task analysis to inform the design process. A companion paper demonstrated an ecological interface that integrates both work-domain- and Task-based information. A second ecological interface was created, drawing exclusively from the traditional work-domain-based analysis. Professional operators used the novel interfaces in an industrial petrochemical process simulator to monitor for, diagnose, and respond to several types of process events. Operators using the work-domain-based ecological interface completed trials more quickly and executed fewer control actions than their counterparts using the current process displays. Operators using the Integrated (Task- and work-domain-based) ecological interface also showed these benefits and, in addition, showed improved fault diagnoses and better performance scores. The implications and opportunities for introducing ecological interfaces into industrial control rooms are discussed.

  • integrating Task and work domain based work analyses in ecological interface design a process control case study
    Systems Man and Cybernetics, 2007
    Co-Authors: Greg A. Jamieson, Christopher A Miller, W H Ho, Kim J Vicente
    Abstract:

    In this paper, we present a case study wherein several work analysis methods were incorporated in the design of a graphical interface for a petrochemical production process. We follow this case from the application of the work analysis methods, through the consolidation of information requirements, to the design of a novel interface that integrates the requirements. The findings confirm earlier assertions that Task-based and work domain-based analysis frameworks identify unique and complementary requirements for effective information systems that are intended to support supervisory control of complex systems. It further provides the first industrial demonstration of ecological interface forms based on Integrated Task-and work domain-based work requirements.

  • Integrated Task and motion planning in belief space
    The International Journal of Robotics Research, 2013
    Co-Authors: Leslie Pack Kaelbling, Tomas Lozanoperez
    Abstract:

    We describe an Integrated strategy for planning, perception, state estimation and action in complex mobile manipulation domains based on planning in the belief space of probability distributions over states using hierarchical goal regression (pre-image back-chaining). We develop a vocabulary of logical expressions that describe sets of belief states, which are goals and subgoals in the planning process. We show that a relatively small set of symbolic operators can give rise to Task-oriented perception in support of the manipulation goals. An implementation of this method is demonstrated in simulation and on a real PR2 robot, showing robust, flexible solution of mobile manipulation problems with multiple objects and substantial uncertainty.
