OBJECTIVE This research directly tests the relationship between comprehension probability of highway signs and the extent to which they comply with three ergonomic principles of design: sign-content compatibility, familiarity, and standardization. BACKGROUND A recent study that evaluated comprehension of traffic signs in four different countries showed that comprehension level varies widely a...

Heuristic Evaluation is a well established method for evaluating a user interface (UI) of an interactive application [1]. This method belongs to the class of informal evaluation methods since the evaluation is performed on the basis of evaluator expertise and knowledge. One characteristic of heuristic evaluation is to guide evaluators by providing them a small set of predefined heuristics rathe...

The objective of this study was to explore the role of objects in integrating ergonomic knowledge in engineering design processes. An engineering design case was analyzed using the theoretical concepts of boundary objects and intermediary objects: Boundary objects facilitate collaboration between different knowledge domains, while the aim of an intermediary object is to circulate knowledge and ...

The Carpal Tunnel Syndrome (CTS) and associated risk factors for shocker manufacturing industries in Haryana were carried out. A comparison of CTS and other upper hand extremities amongst traditional and semi-ergonomic shocker manufacturing workers in actual industrial environment has been analysed through questionnaire and physical tests. Fisher’s exact test and ‘t’ test are used for statistic...

New technologies are changing the face of information services and how those services are delivered. Libraries spend a great deal of time planning the hardware and software implementations of electronic information services, but the human factors are often overlooked. Computers and electronic tools have changed the nature of many librarians' daily work, creating new problems, including stress, ...

The objectives of this study were to investigate the rate of cumulative trauma disorders (CTDs) in the upper body and to describe the associations of such disorders with ergonomic parameters in a group of data entry operators. A total of 173 data entry operators volunteered to take part in the study. Questionnaires were used to investigate their medical history. Diagnoses of CTDs were made with...

Der vorliegende Beitrag beschreibt das Projekt „Integriertes Ergonomic Customizing – ErgoCust“. Gegenstand des Projekts ist die konsequente Einbindung software-ergonomischer Ziele, Instrumente und Methoden in die unternehmensspezifische Anpassung neu einzuführender SAP-Software, um von Anfang an Usability der Software sicherzustellen. Dazu wird im Projekt in Kooperation mit der SAP AG zunächst ...

Activation of back musculature during work tasks leads to fatigue and potential injury. This is especially prevalent in dentists who perform much of their work from a seated position. We examined the use of an ergonomic dental stool with mid-sternum chest support for reducing lower back muscle activation. Electromyography of lower back extensors was assessed from 30 dental students for 20 s dur...

The purpose of the study was to determine the impact of an ergonomic program on perceived stress ratings, injury rates and patient care. After implementation of the ergonomic program, the perceived stress ratings by nursing staff were lower than those ratings at the control hospital and the patients felt more comfortable and secure during patient handling tasks than the patients at the control ...
