SADOC 4 belongs to a new generation of land and naval defense command and control systems equipped with technology based on evolving human-machine interaction paradigms. SADOC 4 is an update from the use of dedicated hardware devices (pedals and keyboards) to a multi-touch mode that reorganizes operator tasks and redefines the dynamics of access to commands and information. The system also employs ergonomic principles, reducing decision-making times and defining new working logics while respecting the same operational needs. The designers involved the end-users right from the beginning as the key to ensuring a high-quality user-centric product.
