Influence of Vibrotactile Signal Parameters on Human Perceptual and Behavioral Responses for Forearm-Wearable Devices

摘要

Wearable vibrotactile devices are increasingly used to communicate robots' states to humans, especially in scenarios requiring physical responses like reaching for handovers. For accurate information transfer, vibrotactile signal design is critical, particularly on the forearm circumference, where anatomical variations may influence perception and behavior. Designing such signals involves selecting appropriate parameter combinations while considering intra-individual and individual variability. However, the influence of signal parameters-such as amplitude (AMP), duration of stimuli (DoS), and inter-stimulus interval (ISI)-on perceptual and behavioral responses across forearm sections remains underexplored. This study addresses this gap by statistically analyzing the relationship between these parameters and human responses across two forearm sections. The findings provide insights for designing practical forearm-wearable vibrotactile systems, enhancing human-machine interaction in applications requiring rapid, precise responses.
