Deviation of normative pathEfficiency measurementsPERFORMANCE MEASURESHere, the performance measures are detailed. They are presented in tables for everytask and separated from participant and the kind of feedback received. For visualhapticfeedback (VH) and visual feedback (V).Differences in Time must not be taken into consideration due to the effectprovoked by the curves and cars coming in the other direction. When any of thesefacts occur, the driver waits to make the task.Task 1: Go to one item in the main menuTask 1Participant 1 Participant 2 Participant 3 Participant 4VH V VH V VH V VH VTime 12.37 2.50 1.58 4.40 3.97 3.65 2.62 4.39Speed 68.83 76.94 81.91 81.25 74.28 83.24 85.86 91.15Deviation ofnormative path0.047 0.078 0.250 0.149 0.070 0.172 0.033 0.139Table 4.2 Performance measures for task 10.250.20.150.10.05VHV0Figure 4.3 Deviation of normative path and media for task 1For task one, the media of deviation of normative path for the visual-hapticfeedback is lower than the ones for visual feedback. For the participant two thedeviation of the normative path for visual-haptic feedback is higher than the one forvisual feedback (figure 4.3).55
