Abstract: Currently the most common ergonomic experiments often do not have sufficient external validity. To overcome this negative factor it is important to develop formalised and analytical methods of studying human performance. In this work authors describe the morphological analysis of tasks offered by systemic-structural activity theory. Morphological analysis is a general method for non-quantified modelling of various objects. In systemic-structural activity theory it is a systemic qualitative description of the structure of designed and often not yet existing activity. Such morphological analysis facilitates farther quantitative analysis of the operators' performance. It allows not just to optimise the methods of performance but also to improve equipment and HCI design.
Keywords: systemic-structural activity theory; SSAT; experimental methods; analytical study; qualitative systemic analysis; morphological analysis.
