User-centred design approach, CBRN recognition

Need

Human Design Group is assisting the Bertin Systèmes teams, on behalf of the DGA, in implementing a user-centred design approach to define CBRN collection and recognition products.

To provide the CBRN teams of the French Army and Air Force with hardened CBRN aerosol sampling and reconnaissance products adapted to the highly constrained operational context (CBRN uniform, climatic conditions, non-biologist personnel, etc.);

Involve operational staff in the definition of products by requiring the manufacturer, Bertin Systèmes, to implement a process of user-centred design.

Intervention

Human Design Group was called in to define and apply the user-centred design, carry out ergonomic studies in support of Bertin Systèmes' design teams and ensure that human factors requirements are taken into account in the design:

  • Definition of the human factors integration plan describing how the process of integrating human factors will be implemented. user-centred design;
  • Analysis of the future context of use and operational tasks as well as human factors issues on current procedures;
  • Design assistance for the integration of ergonomic requirements: product ergonomics and software ergonomics;
  • Leading user working groups throughout the design process;
  • Management of user tests on volume mock-ups and prototypes to evaluate and validate the solutions selected.

Results

  • Management of the ergonomic requirements of the DGA specifications through the implementation of the user-centred design;
  • Design support: physical and software HMI specifications, definition of the faceplate, illustrated user instructions and logos ;
  • Two user test sessions: on physical mock-ups (Air Force firefighters, BA Villacoublay) and then on prototypes (CBRN operational staff of the Land and Air Forces, Fontevraud);
  • Proven satisfaction among operational staff in terms of ease of use, leading to greater product acceptability.
