Abstract

Visual and auditory guidance in smart glasses suffers from distraction and noise sensitivity. To address these limitations, haptic feedback has been explored, and nose-pad vibrotactile navigation offers a promising approach, yet the effect of stimulus intervals is unexplored. This study compared cueing intervals of 0.3 s (high frequency) and 1.0 s (low frequency) in a direction-finding task. Results showed that the high-frequency condition reduced task completion time but exhibited overshooting tendencies and induced user discomfort. Although both conditions showed comparable workload and usability, participants reported trade-offs between responsiveness and comfort, suggesting context-adaptive intervals.
