The paper discusses new trends in developing and implementing methods of workplace analysis. It presents a sample method of ergonomic workplace evaluation developed at the Poznañ University of Technology. The method is a response to the industrial sector's demand for tools supporting occupational risk assessment. The authors also present opportunities and benefits of applying the method in occu...

This paper presents a new gesture based approach for interactive ergonomics evaluation, and especially adaptation of physically disabled people’s workplaces. After a general survey of existing tools, we describe the requirements to perform ergonomic analysis for disabled persons by using a virtual reality approach. We specifically propose a framework unifying the synthesis and the analysis of a...

Occupational hazards exist, if the design of the work situation is not in accordance with ergonomic design principles. At assembly lines ergonomics is applied to the design of work equipment and tasks and to work organisation. The ignoring of ergonomic principles in planning and design of assembly work leads to unfavourable working posture, action force and material handling. Disorders of the m...

Introduction and Objective. Bleeding is an important complication in liver transections. To determine the safety and efficacy of Debakey forceps for liver parenchymal transection and its ergonomic advantages over clamp crushing method we analysed our data. Methods. We used Debakey crushing technique in 100 liver resections and analysed data for transection time, transfusion rate, morbidity, mor...

Improper application of an ergonomic analysis tool increases the likelihood of high-risk jobs not being detected, thus jeopardising worker’s health. Likewise, significant time and cost may be incurred by redesigning jobs improperly identified as high risk. Utah Intelligent Data Driven Ergonomic Assessment System (IDDEAS) is an expert system that aggregates the outputs of multiple analysis tools...

Human–machine-interaction studies complex communication and interaction principles between people and computers. HMI research is concerned with a wide field of related topcis covering the realisation, evaluation of interactive machine and computing systems. It furthermore covers knowledge representation, displaying techniques, signal processing, pattern recognition, human factors, haptics and r...

Operating a website with one hand on a touchscreen mobile phone remains a challenging task: solutions to adapt websites for mobile users do not address the ergonomic peculiarities of one-handed operation. We present the design and evaluation of the One Hand Wonder (OHW) – an easily-adaptable cross-platform JavaScript framework to support one-handed website navigation on touchscreen smartphones....

In manufacturing, control of ergonomic risks at manual workplaces is a necessity commanded by legislation, care for health of workers and economic considerations. Methods for estimating ergonomic risks of workplaces are integrated into production routines at most firms that use the assembly-type of production. Assembly line re-balancing, i.e., re-assignment of tasks to workers, is an effective ...

A comparison of 14 currently applicable wood harvesting systems was assessed with respect to ergonomic point of view. For this purpose, the research method, based on the Hodges-Lehmann rule and the integrated work-severity rate of single machinery, was developed for ergonomic evaluation of cut-to-length, tree-length and full-tree harvesting systems. Altogether, about 130 different parameters of...
