Conception de l'interaction homme-machine et partage d'autorité: application aux systèmes de drones

This paper presents a systematic method for designing the Human-Computer Interaction for a variety of contexts. Elaborated for future Unhabited Air Systems (UAS), this method is based on the "authority sharing" concept (tasks allocation dynamically between the user and the computer system). Most of UAS consider only two modes for controlling and commanding the air vehicles: "full manual" or "full automatic". Several modes in-between can be defined. These modes, called "operative modes", are implemented in the system and activated depending on the evolutions of the context (e.g. breakdown management, dynamic re-planning or an increasing workload). Our method is the result of a classic task analysis for the HCI design and an analysis of the user/automaton capabilities ensuing from the automation domain. This paper details this method applied to a real use-case based on a feedback from past experience on the trajectory management in UAS.
