New methodology to explore the role of visualisation in aircraft design tasks

Abstract

A toolbox for the assessment of engineering performance in a realistic aircraft design task is presented. Participants solve a multidisciplinary optimisation (MDO) task by means of a graphical user interface (GUI). The quantity and quality of visualisation may be systematically varied across experimental conditions. The GUI also allows tracking behavioural responses like cursor trajectories and clicks. Behavioural data together with evaluation of the generated aircraft design can help uncover details about the underlying decision making process. The design and the evaluation of the experimental toolbox are presented. Pilot studies with two novice and two advanced participants confirm and help improve the GUI functionality. The selection of the aircraft design task is based on a numerical analysis that helped to identify a 'sweet spot' where the task is not too easy nor too difficult.
