Determining the Minimal Deviation Limit for Haptic Feedback in Veering Correction during Blindfolded Walking

This paper explores the minimal deviation limit for haptic feedback in correcting veering during blindfolded walking. Participants were asked to walk in a straight line, with deviations from this trajectory triggering haptic feedback at predetermined intervals. Results revealed that haptic feedback significantly reduced veering, with the 1 m and 2.5 m deviations being the most effective. Factors such as leg dominance, left-right confusion, and gender did not significantly affect the outcomes. The cognitive workload was evenly distributed across the task, and participants perceived the tactile feedback as "about right" in all conditions. These findings suggest that haptic feedback is valuable in correcting veering in the absence of visual cues.
