The introduction of greater machine “intelligence” to support users' attempts to continuously comprehend a machine tends to take place through displays and software. An important, but often overlooked, source of information is provided by the appearance of the machine. Use of an “intelligent” approach to simultaneous formation of machine surfaces, volumes and behaviors allows the designer to best distribute information content to “hard” and “soft” forms. RichardsonSmith has had the opportunity to build human factors/appearance strategies using this approach. Our emphasis has been to aid the user in learning how to operate the machine primarily by means of the application of shape, texture, color, typographic and dynamic control/display elements in a meaningful way.

Abstract Current prototyping frameworks are often prompt-based and heavily rely on designers’ experience. The lack of systematic guidelines in prototyping activities causes unwanted variation in the quality of the prototype. Notably, there is limited, or no prototyping framework exists that enables human factors engineering (HFE) guidelines be part of the early product development process. In this paper, a pre-prototyping framework is proposed to render human-centered design strategies to guide designers before the hands-on prototyping activity starts. The methodology consists of extracting key factors related to prototyping and human factors engineering principles based on an extensive literature review. The key elements are then combined to form the prototyping categories, dimensions (theory), and tools (practice). The resulting prototyping framework can be used to develop prototyping strategies consist of theoretical guidelines and practical tools that are needed during the prototyping of human-centered products. The framework provides systematic guidance to designers in the early stages of the design process so that designers, in particular novices in ergonomics and human factors, can have a head start in building the prototypes in the right direction. Finally, a case study is presented to demonstrate a walk-through and efficacy of the proposed pre-prototyping framework.

Vaccination Knowledge

This study was designed to investigate the knowledge, beliefs, and behaviors about rotavirus infection and its vaccination in a sample of parents in Naples, Italy. The survey was conducted between June and December 2018 among parents of children aged 3 months to 3 years. A total of 40.7% of the study subjects declared that they had heard about rotavirus infection and 60.8% and 59.2% were aware about the vaccination and of its availability in Italy. Parents with a child aged <1 year and those who reported the physicians as source of information were more likely to have heard about rotavirus infection and to know that the vaccination is available in Italy. More than half (56.4%) were worried that their children could have a rotavirus gastroenteritis and this was most likely to occur in those who have heard about rotavirus infection. Only 15.3% declared that they had immunized their children against rotavirus infection. Parents who considered it dangerous for their children to contract the rotavirus gastroenteritis, those who considered the rotavirus vaccine useful, and those who had received information by physicians were more likely to have vaccinated their children against the infection. More than half of the parents who did not immunize their children expressed their willingness to vaccinate them. Developing and implementing additional public education programs are needed for better knowledge toward rotavirus infection and vaccination and a high coverage among parents.

© 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group. Polarimetric Synthetic Aperture Radar (PolSAR) images are an important source of information. Speckle noise gives SAR images a granular appearance that makes interpretation and analysis hard tasks. A major issue is the assessment of information content in these kinds of images, and how it is affected by usual processing techniques. Previous works have resulted in various approaches for quantifying image information content. In this paper, we study this problem from the classification accuracy viewpoint, focusing on the filtering and the classification stages. Thus, through classified images, we verify how changing the properties of the input data affects their quality. The input is an actual PolSAR image, the control parameters are (i) the filter (Local Mean, LM, or Model-Based PolSAR, MBPolSAR) and the size of their support, and (ii) the classification method (Maximum Likelihood, ML, or Support Vector Machine, SVM), and the output is the precision of the classification algorithm applied to the filtered data. To expand the conclusions, this study deals not only with Classification Accuracy but also with Kappa and Overall Accuracy as measures of map precision. Experiments were conducted on two airborne PolSAR images. Differently from what was observed in previous works, almost all quality measures are good and increase with degradation, i.e. the filtering algorithms that we used always improve the classification results at least up to supports of size 7 × 7.

Despite the fact that keyboard issued commands (KICs) are more efficient than other command methods, experienced users often do not adopt them. In order to examine the factors underlying this phenomenon, a study is presented which investigated the relationships between users' level of knowledge with Microsoft Word, the importance they placed on the costs and benefits of using KICs, and how these factors related to the use of KICs in Microsoft Word. Results indicate that benefits are more strongly associated with the actual use of KICs than costs. The application of these findings to the human factors domain and the implication of the results to facilitate the adoption of efficient techniques and behaviors are discussed.

A major source of qualitative information in nuclear power plant control rooms is provided by the annunciator system. In many control room operations the alarm system is the initiating stimulus for operator response. Annunciators are an especially critical source of information in an emergency. For this reason, sound annunciator design and layout are crucial to efficient and safe nuclear power plant operation. Over the past few years, several investigators have determined that annunciator systems fail to fulfill the intended purpose. Human factors engineering principles often have been ignored or violated. Much work is needed to optimize the man-machine interface of annunciator systems. This paper discusses the importance of human factors criteria for consistency, accuracy, readability, position, and priority in the design of annunciator systems. The areas of functional grouping and prioritization, standardization of window nomenclature and format, and color coding are reviewed and evaluated. Additional problem areas in the design of an annunciator system are identified.

Objective Address the alarm problem by redesigning, reorganizing, and reprioritizing to better discriminate alarm sounds and displays in a hospital. Background Alarms in hospitals are frequently misunderstood, disregarded, and overridden. Method Discovery-oriented, intervention, and translational studies were conducted. Study objectives and measures varied, but had the shared goals of increasing positive predictive value (PPV) of critical alarms by reducing low-PPV alarms in the background, prioritizing alarms, redesigning alarm sounds to increase information content, and transparently conveying who initiated alarms. An alarm ontology was iteratively generated and refined until consensus was achieved. Results The ontology distinguishes five levels of urgency that incorporate likely PPV, three categories for who initiates the alarm (hospital staff, patient, or machine), whether it is clinical or technical, and clinical functions. Conclusion This unique collaboration allowed us to make progress on the alarm problem by making unintuitive leaps, avoiding common missteps, and refuting conventional healthcare approaches. Application Hospitals can consistently redesign, reorganize, reprioritize, and better discriminate alarms by priority, PPV, and content to reduce nurse response times.
