Could branding influence user interface interaction on emergency medical devices? Using eye-tracking technology to assess user's visual attention when viewing public access defibrillators

Abstract

Introduction: Public access defibrillators (PADs) are commonly used by untrained rescuers, who require graphical user interfaces (GUIs) which enable rapid navigation to the critical tasks. Branding may help users familiarise themselves with PADs, but whether it induces unnecessary additional cognitive processing or becomes a distraction is unknown. This study utilized eye-tracking technology to assess whether branding on PADs distracts the user from the power and shock buttons, which are critical Areas-of-Interest (AoI) on the GUI.
