The System Usability Scale (SUS) is the most widely cited and most widely used of the User Experience Scales (UX). To date, there is no scientifically validated translation into French of this scale. This article therefore proposes to use a first French version of the SUS, the F-SUS, to measure its sensitivity and meaning. The sensitivity of the F-SUS was studied by applying it to 11 different interactive systems (websites, mobile application, expert systems), with 439 users. The scores of these systems were compared in order to verify that they were sufficiently differentiated. The measure of significance was to replicate the Bangor et al ( 2008) study, asking F-SUS respondents to qualify the system they were assessing using 7 adjectives. These adjectives were then positioned on the overall F-SUS score out of 100.
