Supporting Usability Evaluation of Multimodal Man-Machine Interfaces for Space Ground Segment Applications Using Petri net Based Formal Specification

International audienceThis paper describes the issues raised by the evaluation of multimodal interfaces in the field of command and control workstations. Design, specification, verification and certification issues for such Man-Machine Interfaces (MMIs) have been already identified as critical activities. This paper focuses on the issues raised by evaluation of their usability evaluation. We first present a formalism (Interactive Cooperative Objects) and its related case tool (PetShop) for the specification of such MMIs and then show how the models built can support the usability evaluation phase. As a case study we present a multimodal interaction for 3D navigation in a 3D satellite model
