TL;DR: Data obtained from eye movements can significantly enhance the observation of users' strategies while using computer interfaces, which can subsequently improve the precision of computer interface evaluations.

TL;DR: It was concluded that, based on the criteria applied in this study, epidemiologic evidence for manual materials handling as risk factor of back disorders is present, but largely based on cross-sectional studies with inherent methodological weaknesses.

TL;DR: The proposed methodology provides practitioners with a structured approach to select the best interface based on usability criteria and measures and is demonstrated in the interface design of a database system used to analyze trip cases information of nuclear power plant.

TL;DR: In this article, the authors examined the effects of aging on performance and preferences for two computer pointing devices (e.g. mouse and trackball) and found that older adults move more slowly than younger adults, particularly for distant targets, yet their movements were less variable.

TL;DR: In this article, the authors conducted an analysis on 25,291 manual materials handling (MMH) tasks obtained from 2442 reports from industrial locations throughout the US. The tasks consisted of 10,101 lifts, 7461 lowers, 1879 pushes, 1866 pulls and 3984 carries.

TL;DR: In this paper, the relationship among slip resistance, tile surface roughness, surface conditions and slipmeters used was investigated, and the results indicated that the effect of surface roughs on friction index depends on the slipmeter used.

TL;DR: In this paper, the influence of eye level and low monitor locations on the head and neck posture of subjects performing a word processing task was described, and it was shown that lower computer monitor placements may be beneficial.

TL;DR: In this paper, the characteristics of typical manual handling tasks (lifting, lowering, pushing, pulling and carrying) performed at 2442 industrial locations in the United States were tabulated and summarized into median composite tasks.

TL;DR: In this paper, the authors evaluate different methods to assess push and pull forces, describe measures of exposure to pushing and pulling, and consider measurement strategies for assessment of exposure of workers to push and pulling.

TL;DR: The anthropometric data collected in this project provide the designers and engineers the basis for designing safe, healthy, and comfort work environment and facilities for Taiwanese workers and can be analyzed and used for production and inventory planning to meet the market demand and reduce the costs.

TL;DR: The results demonstrate that pre-employment screening procedures for endurance capacity, based on readily accessible personal factors, have a low efficiency and guidelines for occupational shoulder loads in the investigated range should be constructed with consideration to the specific endurance properties of shoulder muscles.

TL;DR: In this article, the authors investigated the effect of the input devices on the performance of text editing with two different data input devices, a mouse and a track-ball, in 20 healthy VDU operators.

TL;DR: A rule-based inference model is proposed which is useful in product design development having complex relationship with human Kansei of any industry and can be made available to evaluation method for the analysis of reasoned results.

TL;DR: The results of this study can aid ergonomists in designing and evaluating product alternatives based on subjective data obtained by magnitude estimation.

TL;DR: In this article, the authors show that there is a dire need to train workers in manufacturing organizations and thereby improve the overall e!ectiveness and e$ciency of such organizations.

TL;DR: Assessment of exposure to manual handling, using a frequency-oriented log, appears to provide relevant information for designing back pain prevention policies in nursing.

TL;DR: In this paper, the authors examined the signaling property of color with signal words in warning messages to attract attention of users and to communicate the hazards associated with a product and concluded that shape or other graphical configurations may serve better than color to convey level of risk.

TL;DR: The authors found that the presence of a signal word and adding specific source information (telling who is giving the message) was found to increase credibility judgments and compliance intentions for alcohol, cigarette, and iron supplement warnings.

TL;DR: The study showed the specific kinds of problems that occur in an assembly plant, rather than nonspecific terms like overexertion injury, cumulative trauma disorder, etc.

TL;DR: In this paper, the effect of sound type, training cue and cue source on people's ability to learn and retain a set of twelve warning-type sounds was examined. And the results showed that the difficulty with which alarm type sounds can be learned depends not only on the type of sounds to be learned, but the way in which they are learnt.

TL;DR: In this paper, the authors compared the NIOSH substantiation approaches and the respective data of the literature sources: essential results referred to by NIOSH or NIOSH-authorized presenters are not included in or cannot be reproduced from the cited sources.

TL;DR: Results of studies on muscular activity patterns during movements which support the notion that chronic pain may be evoked by overuse syndromes at the muscular fiber level are presented.

TL;DR: In this article, an integrated Virtual Reality-based environment is developed for the analysis of assembly product and jig designs. But this approach is dependent on the experience of the tool designer and the limited visualization possible on commercial CAD systems.

TL;DR: In this article, a dynamic simulation model was developed for biomechanical analyses of lifting activities performed in the sagittal plane, which can be used to predict motions for various sagittal-plane lifting tasks.

TL;DR: Maximum acceptable force for wrist extension with a pinch grip is smaller than any of the other motions investigated so far, and has relevance to industry.

TL;DR: Comparisons of variables between fatal and nonfatal accidents in Korean manufacturing industries for the years 1991-1994 can be used to develop more effective accidental occupational death and injury prevention programs for manufacturing industry.

TL;DR: The CTD risk assessment model predicts CTD incidence rates or a relative risk potential for industrial jobs based on task and hand motion parameters which allows appropriate medical and engineering personnel to intervene quickly to redesign the risky jobs and thus potentially reduce the injuries and medical costs.

TL;DR: In this paper, the authors investigated the distribution of contact pressure and forces between the seated human subjects and a visco-elastic seat under vertical vibration and found that the maximum variations in the ischium pressure and the effective contact area on a soft seat occur near the resonant frequency of the coupled human-sear system (2.5-3.0 Hz).

TL;DR: In this paper, the effects of handle types of garden tools on ergonomic effectiveness, user satisfaction in terms of work performance, and subjective judgment of tactile feel and control were evaluated.

TL;DR: The study demonstrates the importance of quantification of joint loads in occupational risk assessment of the neck by calculating joint moments in combination with information on muscle activity and strength to estimate different tissue loading of significance.
