Studying the Perception of Vibrotactile Stimulation on the Arm via a Modular Wearable Sleeve

Résumé

This study investigates the perception of vibrotactile stimulation on the human arm using a modular wearable sleeve equipped with vibrotactile actuators. We examined three perceptual aspects: vibration localization, apparent haptic motion (AHM), and two-point discrimination (2PD). Our findings indicate that users can accurately identify the location of four distinct vibrotactile stimuli with over 95% accuracy across the wrist, forearm, upper arm, and shoulder. Additionally, participants demonstrated reliable perception of apparent motion, though minor misclassifications in directional cues were observed in the upper arm and shoulder regions. The two-point discrimination results revealed that spatial acuity decreases from the wrist to the upper arm, with the shoulder exhibiting better discrimination than expected. These findings provide preliminary insights for the design of wearable haptic feedback systems in applications such as rehabilitation, virtual reality, and assistive navigation.
