Investigating Multimodal Augmentations Contribution to Remote Control Tower Contexts for Air Traffic Management

Abstract : The present study aims at investigating the contribution of multimodal modalities to the context of Remote Towers. Interactive spatial sound and vibrotactile feedback were used to design 4 different types of interaction and feedback, responding to 4 typical Air Traffic Control use cases. The experiment involved 16 professional Air Traffic Controllers, who have been called to manage 4 different ATC scenarios into ecological experimental conditions. In two of the scenarios, participants had to control only one airport (i.e., Single Remote Tower context), while in the other two scenarios participants had to control simultaneously two airports (i.e., Multiple Remote Tower context). The augmentation modalities were activated or not in a balanced way. Behavioral results highlighted a significant increase in overall participants performance when the augmentation modalities were activated in Single Remote Tower context. This work demonstrates that some types of augmentation modalities can be used into Remote Tower context.
