 During the evaluation of the mainstudy we noticed that we should have included the time of the two evaluation systems in the data collection in order to get a quantitative statement regarding the suitable alternative. Unfortunately this was missed and the ranking system, the likert evaluations and the ground truth data, i.e. the Fitts´Law tests were compared against each other. The data was used to determine that the overall result, i.e. for all 24 participants,​ the order of the mouse tracking speeds for the Likert Scale System and the Ranking System was the same. If the time of the respective evaluation had been determined, a statement could be made as to whether the ranking system delivers the same overall result despite a different time expenditure. The results of the individuals were also considered, a distinction can be made here, but some respondents indicated that the assessment of the Fitts´ Law test processing was difficult due to the small temporal difference in the results, i.e. the temporal difference is sometimes in the hundredths of a second range. During the evaluation of the mainstudy we noticed that we should have included the time of the two evaluation systems in the data collection in order to get a quantitative statement regarding the suitable alternative.
