The article discusses the performance of participants using a TBC controller in various walking speeds. It was observed that at slower speeds, participants exhibited significant variability in interaction torques and muscle activation, indicating inconsistent performance. However, as the walking speed increased to moderate levels, the performance metrics stabilized, showcasing improved human adaptation and consistency. This study highlights the importance of examining interaction portraits and individual adaptation strategies to better understand human-machine interactions in the context of assistive technologies.
The study reveals that participants exhibited significant performance inconsistency at ultra-slow and slow walking speeds, affecting both spatial and temporal dynamics, improving at moderate speeds.
As walking speed increased to moderate levels, a notable reduction in variability in interaction torque and muscle activation was observed, suggesting improved adaptation strategies.
