THE PRACTICE OF TRIANGULATION

摘要

Triangulation in the practice of geographical Navigation is a way of combining positional data, based on the assessed accuracy of that data, to derive the most probable position of an object. In Ergonomics, 'Triangulation' has little to do with triangles but much to do with the analyses of mires of collected qualitative and quantitative information. It involves the combination of information in such a way as to give substance and rigour to the results of ergonomic investigations. This is especially true if the study is concerned with real work situations under strong cost and time constraints and using only a few test subjects. The facets of work that can be examined through this form of analysis include system cognitive functions (MacLeod, 1998), design consistency, operators' work rules, their methods of system management & supervision, and their approaches to system control.
