HUMAN-TO-SYSTEM INTERACTION DEFINITION METHODS USED FOR ERGONOMICS ASSESSMENT

Abstract

The paper considers the application of various human-to-system interaction modeling methods used for ergonomics assessment. The existing human-to-system interaction (activity) modeling objectives and methods have been categorized. A simple case study demonstrates the capabilities and limitations of the structural activity modeling methods such as the generalized structural methods, the hierarchical and table-based problem solution methods, etc. It is shown that the structural functional analysis method is very promising for ergonomic assessment. It is shown that a less formal approach enables more creativity; however, in this case the results are more dependent on the expert’s qualification and experience in ergonomics and subject matter.
