A Work Domain Analysis for Diabetes Management

Proceedings of the Human Factors and Ergonomics Society Annual Meeting 2003年第12期47卷 1516 - 1520页

作者： Laura K. Thompson Janna C. L. Hickson Catherine M. Burns Advanced Interface Design Lab Systems Design Engineering University of Waterloo Waterloo Ontario Canada

This paper discusses the results of a Work Domain Analysis (WDA) applied to the management of diabetes. The goal is to develop a conceptual framework to help diabetic patients understand and manage their disease. The results of the WDA will be used to design and implement mobile and desktop information displays that will be used by the patient and their health care team. This poses additional challenges in demonstrating if and how Ecological Interface design can be used to design medical information displays on various mobile devices. When applied to this medical domain, the usefulness of the WDA to the design of medical information displays becomes restricted because of the complex, interconnected processes involved and the limited amount of sensor data available. Alternatively, the Work Domain representation can be used as a teaching resource or used to define requirements for future monitoring technologies.

Atomically thin black phosphorus, also known as phosphorene, is an emerging two-dimensional (2D) material, which has attracted increasing attention due to its unique electronic and optoelectronic properties. However, the reduced thermal stability of phosphorene limits its suitability for high-temperature fabrication processes, which could be detrimental for the performance of phosphorenebased devices. Here, we investigate the impact of doping by Al and Hf transition metal adatoms on the thermal stability of phosphorene. The formation of Al–P covalent bonds was found to significantly improve the thermal coefficients of the Ag1, B2g, and Ag2phonon modes to 0.00044, 0.00081, and 0.00012 cm–1·°C–1, respectively, which are two orders of magnitude lower than those observed for pristine P–P bonds (~0.01 cm–1·°C–1). First-principles calculations within the density functional theory framework reveal that the observed thermal stability enhancement in the Al-doped material reflects a significantly higher Al binding energy, due to the stronger Al–P bonds compared to the weak van der Waals interactions between adjacent P atoms in the undoped material. The present work thus paves the way towards phosphorene materials with improved structural stability, which could be promising candidates for potential nanoelectronic and optoelectronic applications.

Mental Models and Ecological Interface design: An Experimental Investigation

引用

Proceedings of the Human Factors and Ergonomics Society Annual Meeting 2002年第3期46卷 270 - 274页

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

We studied the impact of Ecological Interface design (EID) displays on mental models using the DURESS II simulator. To assess mental models we used a card sorting exercise, a network building exercise based on the Abstraction Hierarchy, and a system behavior prediction exercise. Participants in the EID condition performed significantly better on the card sorting and network building exercises, but poorer on the prediction exercise. Our results are mixed, suggesting that EID may improve the understanding of means- end links and yet, not improve the ability to predict system behavior. The relatively limited experience of participants with the interface as well as our selection of knowledge elicitation techniques may have influenced these results. More research is needed to fully evaluate the impact of EID on mental models.

Usability Evaluation of a Mobile Ecological Interface design Application for Diabetes Management

引用

Proceedings of the Human Factors and Ergonomics Society Annual Meeting 2005年第11期49卷 1042 - 1046页

作者： Jordanna Kwok Catherine M. Burns Advanced Interface Design Lab Department of Systems Design Engineering University of Waterloo Waterloo Ontario Canada

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.

Mental Models and the Abstraction Hierarchy: Assessing Ecological Compatibility

引用

Proceedings of the Human Factors and Ergonomics Society Annual Meeting 2001年第4期45卷 297 - 301页

作者： Olivier St-Cyr Catherine M. Burns Advanced Interface Design Lab Department of Systems Design Engineering University of Waterloo Waterloo Ontario 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.
