A model for cognitive task load prediction: Validation and application
conference paper
This paper summarizes a Cognitive Task Load (CTL) model, which describes the effects of (envisioned) task allocations and support functions on operator performance and mental effort. The CTL-model distinguishes three load factors: the classical measure percentage time occupied, the number of task-set switches and the level of information processing. Recently, the model has been used to guide several system development processes. We present a validation study and an example application for the analysis of envisioned task distributions and support functions on a ship. This CTLanalysis provided requirements for dynamic task allocation and a first design of support functions that extend human capacities for the three factors of the CTL model.
