Determine how specific interface design elements affect cognitive load and perceived usability in intensive care unit ventilators to reduce user error.
Developed experimental prototypes of an intelligent ICU ventilator interface using a participatory design framework.
Administered a feedback survey to 535 healthcare practitioners, including doctors, nurses, medical students, and caregivers.
Analyzed the structural model and hypothesized relationships using the partial least squares method.
Font, color, hierarchy, and control elements demonstrated significant effects on both cognitive load and perceived usability.
Aesthetic graphics, transitions, and animations were negatively associated with cognitive load.
Gestalt principles and interface interactivity were positively linked to perceived usability.
