Haptics Symposium 2024 • #haptics #haptics2024 • https://www.hapticssymposium.org/ • Feeling haptics with our fingerpads is how we achieve manual tasks (e.g., operate a needle or press buttons). Following this, research started adding actuators atop the users’ fingerpads to render haptic feedback for interactive virtual environments. Recently, many have moved away from thick actuators (e.g., vibration motors) and turned to electrodefilms with electrotactile stimulation—allowing users to still feel some sensations through the devices when touching physical objects (e.g., compliance or some macro features). However, we argue that thin devices are not enough to maximize the user’s dexterity. We evaluate how adding small holes to electrotactilefilms can allow direct contact and thus increase haptic permeability, resulting in: (1) improved perception of tactile features; and (2) improved force control in grasping tasks. We demonstrate an interactive experience using electrotactile devices added with holes. The users can perform physical tasks with high dexterity while still benefiting from haptic feedback.
