Wearable haptic devices offer opportunities for subtle, always-available tactile feedback, yet many existing designs rely primarily on vibrotactile actuation, limiting the range of sensations that can be conveyed. This work presents a rotational haptic ring that applies electrostatic adhesion to modulate contact forces during rotation, enabling directional tactile feedback in a compact, ring-worn form factor. By controlling adhesion during rotation, the device can generate variable tactile sensations without relying on large actuators or external surfaces. This work-in-progress explores electrostatic adhesion as a mechanism for rotational haptic feedback, highlighting its potential for compact, low-profile wearable haptics.
