Does folding improve the usability of interactive surfaces in future airliner cockpits? An evaluation under turbulent conditions and varying cognitive load.

Abstract : In recent years, many aircraft manufacturers have proposed inno-vative cockpit concepts based on touchscreens. Although having alarge number of advantages, this type of solution suffers from severelimitations in operational use, in particular, eyes-free interactionis nearly impossible and touchscreens are extremely complex touse during turbulent conditions. We examined the contribution ofphysicality to overcome these weaknesses by introducing a shape-changing touchscreen that offers folds on which the user hand canrest. This surface has been assessed in simulator during pilotingconditions that varied in terms of turbulences and mental workload.Results showed that the folds helped reducing physical effort bystabilizing the arm and hand. This physicality was also associatedwith better performance in the piloting task, as well as with bettersituational awareness of the state of the aircraft’s systems, mostcertainly because the shapes offered by the folds had better visualproperties (salience), making their monitoring less expensive interms of attentional resources.
