Ergonomists and usability engineers encounter test method dilemmas with virtual work environments

Abstract

Today's ergonomists and usability engineers need a broad understanding of the characteristics and demands of complex sociotechnical systems in order to develop virtual work systems and mobile communication tools for workers. Familiarity with appropriate ergonomics tests and evaluation methods is a prerequisite of this understanding. The literature review about ergonomics methods was performed. Applicable, potential and inapplicable ergonomics test methods for virtual work systems have been identified, based on the validity analysis and case example. The large number of available methods is confusing for ergonomists and therefore a hierarchical top-down approach is needed for method selection. The issues highlighted in this paper may be useful for ergonomists and usability practitioners who are participating design processes in complex virtual work environments. © Springer-Verlag Berlin Heidelberg 2007.
