Healthcare applications for small-screen mobile devices are becoming increasingly common for medical professionals and patients. Even so, usability issues including navigation and screen clutter remain a challenge. Ecological interface design (EID) was used to design a patient-oriented diabetes management display for Java-enabled mobile devices, making it one of the first mobile EID (mEID) applications. This paper presents a usability evaluation of the diabetes management application, which compares the mEID display to a modified taskbased display (mEID+Task). The mEID+Task display integrates functional task characteristics such as frequency and necessity;menu structure, item ordering, item labelling, and input scheme were varied. Results showed that normalised trial completion times were moderately faster in the mEID+Task display than in the mEID display, while no differences were observed in trial completion accuracy. Furthermore, the mEID+Task display received higher preference ratings than the mEID display alone. The findings suggest that the usability of mEID displays can be improved by incorporating a task-oriented approach.

Most guidance documents on display design either provide a rigid design standard or a list of high level principles. I argue that neither of these approaches is adequate for a complex display design effort. We need instead to develop a category of higher level "display engineering" principles and methods that can consistently drive a professional display designer to best practices in display design. While this concept of display engineering principles still needs development, I will propose two example display engineering practices, graphical object sensitivity analysis and display design with a margin of safety as examples of what could be gained by establishing a systematic display engineering process.

As new technologies are introduced into the nuclear industry, there is increasing interest in replacing existing hardwired monitoring systems in nuclear power plant control rooms with innovative human-machine interface (HMI) graphical displays. However, investigations into past accidents at nuclear generating facilities have identified human performance limitations arising from HMI design as one of the most important factors in plant safety. Ecological interface design (EID) is a design methodology for HMI graphical displays that attempts to support operator performance for both anticipated and unanticipated events, which are often precursors to serious accidents. The university of waterloo and the university of Toronto are collaborating with the Norwegian Institute for Energy Technology (IFE) to examine the application of EID in the Swedish Forsmark 3 boiling water reactor nuclear power plant. This paper focuses on the design of advanced graphical displays for the turbine-generator systems.

Proceedings of the Human Factors and Ergonomics Society 45th Annual Meeting

作者： St-Cyr, Olivier Burns, Catherine M. Advanced Interface Design Lab Dept. of Systems Design Engineering University of Waterloo Waterloo Ont. Canada

This paper presents a new approach to understanding mental models for complex industrial systems. Using the Abstraction Hierarchy (AH) framework as a way to describe mental models, we propose an approach to assess ecological compatibility between an operator's internal mental model and a model of the environment. In order to do so, we have combined and built upon the previous work of Rasmussen (1979) and Moray (1996). We believe that this new approach can assess ecological compatibility and ultimately provide the operator with a more accurate and complete internal mental model that reflects the reality of the environment. We argue that Ecological interface design (EID) is a way to link mental models and the environment. Future work will be needed in order to assess ecological compatibility. This includes capturing and examining operators' internal mental models, and comparing them with models of the environment.

Proceedings of the XIVth Triennial Congress of the International Ergonomics Association and 44th Annual Meeting of the Human Factors and Ergonomics Association, 'Ergonomics for the New Millennnium'

Computer networks are pervasive and critical to the operation of today's businesses. While most of us take computer networks for granted, network managers who must configure, operate, and fix faults in computer networks face a daunting task that becomes more complex everyday. Ecological interface design has been shown to be a promising approach for complex systems such as power plants or petrochemical systems. Computer networks are a very different work domain characterized by rapid technological change, extreme decentralization, and the existence of "soft" components. This paper presents the first work domain analysis of this new domain creating an abstraction hierarchy for general signal transfer systems and general computing networks. It shows how the abstraction hierarchy can be applied to this new domain and presents the initial work on an ecological interface design for network management.

The objective of this study is to understand how the reason for use (RFU) or the indication for medications are used, its effects on the decision-making process, the implications, and the willingness among prescribers, pharmacists, and patients to share RFU information. Methods, semi-structured interviews were conducted to retrieve the information needed from a total of 60 participants. Results, pharmacists, prescribers, and patients generally have positive opinions about including RFU information in their communications. Conclusion, there is a general agreement among participants that sharing RFU information will improve patient safety. © 2019 American Psychological Association Inc. All rights reserved.

Autocalibration for Creating 2D/3D Displays on Complex Geometric Surfaces

引用

Information Display 2022年第6期38卷 31-37页

作者： Arnold, Katherine Fieguth, Paul Dennison, Andrew Vision and Image Processing Lab University of Waterloo Canada Systems Design Engineering Department University of Waterloo Canada Software Solutions Development Department Christie Digital Systems

Geometric calibration methods tend to rely on precalibrated cameras or real calibration targets. Here we explore the chal-lenge of achieving a sufficiently accurate projector system calibration for complex projection mapping tasks that can rely on neither precalibrated cameras nor calibration targets. Virtual scene models can take the place of a real calibration target for the purpose of providing scene information that is used to refine geometric estimates. Refinement of the display parameters aims to reduce the reprojection error, or the error between the theoretical coordinate (generated from the projection of the scene estimate coordinate by the estimated parameters) and the actual coordinate (obtained from pixel cor-respondences). For Christie installations, the final reprojection error of each pixel should be less than 1 pixel. Mystique was not always so capable. Christie’s research department, Christie labs, has a history of creating solutions for new projection concepts. Part of that strategy has been a long partnership with the university of waterloo, particularly the Vision and Image Processing (VIP) lab in systems design engineering. Graduate students study computer vision and machine learning—topics related to problems often at the heart of techniques—which can be used to bring new ideas, meth-ods, and solutions to Mystique and, by extension, to Christie’s customers. Years of investment in research and development, including partnership with the VIP lab and others, have enabled Mystique to handle challenges beyond any other projec-tor-alignment solution.

Cross modality label fusion in multi-atlas segmentation

Cross modality label fusion in multi-atlas segmentation

引用

作者： Kasiri, Keyvan Fieguth, Paul Clausi, David A. Lab Department of Systems Design Engineering University of Waterloo Waterloo Canada

ISBN: (纸本)9781479957514

Multi-atlas label fusion is a widely used approach in medical image analysis that has improved the accuracy of segmentation. Majority voting, as the most common combination strategy, weighs each candidate in the atlas database equally. More sophisticated methods rely on the intensity similarity of each atlas to the target volume. However, these methods cannot handle those cases in which the atlases and the target image are in different modalities. A new method for label fusion is proposed, based on a structural similarity measure, relying on the structural relationships of features extracted from an undecimated wavelet transform instead of explicit image intensities. The new label fusion method has been tested on simulated and real MR images;segmentation results are promising, and open the door to a wider range of multi-modal approaches. © 2014 IEEE.
