12/14/2006: HFES Talk

Greg A. Jamieson, Ph.D. will be delivering a talk on Thursday (12/14/06) at 1:30 in Olsson 002.

Dr. Jamieson is an Assistant Professor in the Department of Mechanical and Industrial Engineering at the University of Toronto and is a director of its Cognitive Engineering Laboratory. His research interests include the analysis of work in complex systems, the design of interfaces, and cognitive engineering applications in process control, finance, environment, and other emerging areas.

His talk is titled “Ecological interface design for the condenser subsystems of a boiling water reactor.”

Abstract:
Ecological interfaces provide support to operators during both anticipated and unanticipated events as they are designed to be (a) physically and functionally faithful representations of the work domain, and (b) compatible with human information processing mechanisms. A corpus of empirical evidence provides support for these claims. However, the Ecological Interface Design (EID) literature offers few proofs-of-concept at an industrial scale and fewer evaluations under representative conditions in the process industries.

In an effort to demonstrate that EID is viable in the nuclear domain, we have developed a proof-of-concept interface for supervisory control of a boiling water reactor. In this talk, I will describe the analysis and design path for the condenser subsystems of the interface, with specific reference to work domain modeling and the Skills, Rules, Knowledge taxonomy. I will also outline a simulator study conducted to evaluate the interfaces and present some initial results from that study.

05/31/2006: Web Conference Presentation

Yukari (Carrie) Enomoto will present a talk on "Effects of Decision Support on Cardiac Telephone Consultation Process" at 7:00 PM. It will be shown in Olsson 111.

Nursing Cordinators (NCs) at the University of Ottawa Heart Institute (UOHI) fields phone calls from patients who have been discharged and are undergoing home care procedures at a daily basis. The CARDIO project aims to provide tools for the Personal Digital Assistant (PDA) that NCs can use during the phone calls. The Ecological Interface Design (EID) approach is used to identify the information requirements to design the system. Major challenges of the telephone consultation process that are additionally identified by literature review and interviewing the NCs included visibility of patients, individual differences, and lack of standardized procedures. A combination of decision trees and visualization techniques is proposed to aid the process. Implementation of decision trees would help unload mental workload especially accesses to "knowledge in the head" as well as facilitate expert knowledge transfer to less experienced nurses. Visualization tools display integration of multiple-cues from patients in an abstract nature and can be accessed by users at any point of decision process. Preliminary experiment with static images showed that visualization tools helped the decision makers more when the judgement tasks were more complex. A new integrative tool was designed for the second experiment using simulated phone consultations taskes.

05/30/2006: Weekly HFES Seminar

UVA HFES is hosting a weekly seminar every tuesday at 1:00 PM in Olsson 111 where HFES students will be presenting topics related to their research.

The first presenter will be Brendan Hogan, who will be talking about airspace congestion pricing.

Congestion pricing (also called "value pricing") has been studied for a while in the context of ground transportation. It basically has to do with charging more for access to resources during peak times, so as to encourage a more even distribution of demand and a more efficient overall use of available resources. A variant on this is how hotels and airlines get away with charging higher prices during peak demand periods. It's just for revenue management as opposed to congestion management in the case of hotels and airline tickets, but it's a related concept that I'm sure you've experienced.

Congestion pricing in ground transportation is starting to be implemented in different forms in places like London, San Diego, and Minneapolis. If you are interested in some general background on the concept you could check out this webpage: http://www.hhh.umn.edu/centers/slp/projects/conpric/index.htm

In my seminar I'll talk about why this approach has not been used before (or ever really studied) in dealing with airspace congestion, and why I feel now is the right time to pursue this research path. I'll describe the general approach I have in mind to address the problem, and some of the challenges I expect to run into.

If you've read this far, and are curious about some of the issues that would be involved in an airspace congestion pricing situation you could check out this page courtesy our friends in Europe: http://www.eurocontrol.be/care-innov/public/standard_page/project2002_ircs.html

05/03/2006: Talk on Simulating Human Physiology in the Health Care System

David Ross will be giving a talk entitled "Simulating Human Physiology in the Health Care System" on 05/03/2006 from 1:30 - 2:30 in Olsson 005.

Modeling and simulation, and quantitative methods more generally, are established in many niches of medical science. PK/PD simulations support virtually all FDA applications. Clinical trials are grounded in rigorous statistical standards. The burgeoning field of bioinformatics has grown up around problems in gene sequencing. Computer simulations shape research in artificial heart valves, artificial limbs, cancer cell growth, blood chemistry.

In this talk, Dr. Ross will discuss the development and application of a different sort of computer simulation, one with an unusually broad scope: a simulation of the physiological essentials of members of a demographically realistic population. In these simulations, patients with simulated hearts and brains and endocrine systems get diseases, are treated in a simulated health care system, get simulated drugs, and in various other ways mimic the experiences of real patients. Dr. Ross with discuss the general structure of such simulations. He will give examples of the development of particular models used in these simulations, and will give an overview of some technical problems that arise in developing such simulations. Finally, he will discuss applications of these simulations to problems in drug research and health policy.

04/07/2006: Virtual Presentation

Steven Sloman's presentation "Causal Reasoning and Decision Making: Imagination and Choice as Interventions" will be held at 1:00-2:00 p.m. ET

A framework for reasoning about causality has been developed by Spirtes, Glymour, and Scheines (1993) and is reviewed in Pearl (2000). The fundamental idea is that people represent the world by decomposing it into autonomous causal mechanisms that support interventions. On this view, human reasoning is understood as a tool to support human action. I report studies showing that people are highly sensitive to the logic of intervention when reasoning counterfactually, a logic that cannot be reduced to a set of possibilities without a prior causal analysis. The application of the ideas to decision making reveals that good decisions depend on causal analysis and that preferential choice is a form of intervention. I report further studies revealing some of the conditions under which people's choices display this form of rationality.

03/29/2006: Virtual Presentation

Ben Shneiderman's virtual presentation "The Thrill of Discovery- Accelerating Information Exploration" will be presented in Olsson 111 at 11:00 AM.

Exceptional tools for information visualization are becoming more widely used to gain competitive advantages, but the best is yet to come. The next generation of interactive tools will enable communities of users to make successful business decisions even more rapidly. Advances to look for include: 1) systematic strategies for discovery that incorporate the increasingly powerful statistical tools and data mining methods, while accommodating missing and uncertain data. 2) increasingly diverse data types such as time series, patient histories, maps, and social networks, so users can handle a wider array of problems. 3) tighter integration into organizational workflows that amplify individual creativity with the catalytic benefits of social creativity.

These ambitious aspirations are already motivating researchers and inspiring developers. This webcast tours current efforts and proposes grand challenges. Please join us for this informative event.

02/23/2006: Seminar on How Fingertip Skin Microstructures Enhance Touch Sensation

Greg Gerling will be givning a seminar for the department of Mechanical and Aerospance engineering at 3:30 PM in MEC 305.

In this talk, we Professor Gerling describe how our fingertip skin enhances tactile sensation. Solid mechanics models are used to analyze how particular skin microstructures, nearby the slowly adapting type I (SAI) tactile receptors, affect the conversion of edge indentation into coded, neural signals. Results help better explain the SA-I receptors’ neural response and physiological position and may inform the design of electro-mechanical sensors that could interface with the neural system. Emerging from this work is a speculative but intriguing new model of the interaction of skin microstructures with SAI receptors: the lens analogy. This analogy suggests that fingerpad skin microstructure may serve to focus stress/strain to the SA-I receptors just as a convex lens serves to focus light to a point.

02/17/2006 1:00-2:00 pm: Virtual Colloquium

There will be a virtual colloquium on Culture, Expertise and Resource Conflict: Why Meanings Matter

This talk describes an approach to culture and cognition where within group variability is treated as signal, not noise. This view is illustrated for the case of conflict over natural resources among Native-American and European-American hunters and fishermen in Wisconsin. I argue that an analysis in terms of different utilities or super-ordinate goals fails to illuminate the nature of the conflict. Instead our observations suggest that differences in conceptual organization and mental models of nature give rise to meaning differences that mediate misperceptions and stereotyping.

It will be presented by Doug Medin, a Professor of Psychology, and Education and Social Policy at Northwestern University.

02/02/2006: ERICA and Chris Lankford to be featured on ER

ERICA(Eyegaze Response Interface Computer Aid) system will be featured in a February 2 episode of ER. Guest star James Woods, playing a patient suffering from ALS, will use the ERICA system to communicate throughout the show.  Eye Response Technologies chief technology officer and UVA grad Chris Lankford spent over a week on the set supporting the ER staff, controlling the equipment via a remote mouse and keyboard, and appearing for a moment as a hospital technician. ERICA, originally developed at UVA by Professor Emeritus Thomas Hutchinson, gives computer access to persons with disabilities allowing complete control over the computer through eye movement alone. More on ERICA.

01/09/2006: UVA HFES at AIAA Aerospace Sciences Meeting and Exhibit

Justin DeVoge will be presenting the following talk at the 44th AIAA Aerospace Sciences Meeting and Exhibit in Reno, Nevada:

Atmospheric icing plays a critical role in the daily responsibilities and decision making of airline flight dispatchers. To maintain safety, airlines must be sure that dispatchers are trained to a deep understanding of this topic. It is difficult, however, for current training programs to review icing to the depth that is necessary. In addition, systematically designed training products focusing on atmospheric icing do not exist for flight dispatchers. Flight dispatchers and instructors express the need for systematically designed icing training products standardized for flight dispatchers. The field of instructional systems design (ISD) offers methods for the creation of such products. In recognition of the need for flight dispatcher centered training products, this paper discusses the development of a preliminary icing training system for flight dispatchers, framed within a modern ISD model. It focuses on the higher and lower level instructional goals, the content to achieve these goals, and the evaluation materials and strategy to assess the training system.

10/10/2005: UVA HFES at SMC 2005

Matthew Bolton will be presenting the following talk at the 2005 Conference on Systems Man and Cybernetics in Waikoloa Hawaii:

There is a lack of educational technology to support cognitive systems engineering topics such as models of human performance in dynamic environments. This paper describes the Cognitive Systems Engineering Educational Software (CSEES) system, an integrated toolset designed to facilitate curricula related to human judgment and decision-making performance modeling and evaluation. CSEES provides students with the means to generate and analyze performance data using multiple methods. It also includes documentation and tutorials. Its flexible design facilitates adding new judgment and decision making task environments. The paper describes the initial system implementation as a Microsoft Excel addon, a preliminary evaluation as part of a graduate engineering course, and planned future work.
