While the underestimation of MIBREATHE durations might account for the task duration in the case of normal breathing, it may rather relate to the physiological arousal mismatch during MIBREATHE of the apnea swimming task.
Providing the desired and correct image information to the surgeon during the intervention is of crucial importance to reduce the task load and duration of the surgery, while increasing the accuracy and patient outcome.
The task duration was approximately 10 minutes.
The task duration was 5 minutes.
All PD+FOG suffered FOG during the task.
One-way repeated measures analysis of variances (ANOVAs) for each task showed that the task performances were similar across durations in the duration task (main effect of duration, F3,30 = 2.604, p = 0.070, η2 = 0.207) and across orientations in the orientation task (main effect of orientation, F3,30 = 2.506, p = 0.078, η2 = 0.200).
Task completion time, the average task duration for the six tasks in the IVIS condition, is plotted in Fig. 13.
Task completion time reflects the average task duration across the six tasks in the IVIS condition.
The participants were also instructed to fixate their eyes on the fixation point and ignore changes in the task-irrelevant stimulus features (i.e., orientation change in the duration task and duration change in the orientation task), as well as refrain from using a counting strategy to measure the durations in the duration task.
For both subjects A and B, different from the results of tasks 2 and 3, during the entire experiment duration, the angles of the robot arm in the task 1 are almost always the minimum in all of four tasks.
Although the task performances were comparable across different durations in the localizer scans, a one-way repeated measures ANOVA in the main scans showed a significant main effect of duration (F3,30 = 4.824, p = 0.007, η2 = 0.325).
