Results of usability evaluation obtained from our questionnaire. This figure shows the final outcome of the survey carried out in cooperation with RC staff. For this survey, the six-item Likert scale-based System Usability (SUS) questionnaire was used. In order to numerically analyze the survey results, the Likert scale responses were translated to numbers using the following five-point scale: 1 = strongly disagree; 2 = disagree, 3 = neutral; 4 = agree; 5 = strongly agree. Based on the questionnaire outcome, average values (AVG) and standard deviation values (STD) were calculated and graphically presented
